Wholesale Frost Cover: B2B Buyer’s Guide to Types, Quality, OEM, and Sourcing

If you have ever tried to coordinate 15 frost protection SKUs from four different factories—different GSM, different sizes, different packaging, different inspection standards, different ship dates, different return reasons—you already know the problem this article solves.

Frost cover is not one product. It is four product families that share a purpose—protecting plants from frost—but differ completely in structure, materials, quality risks, and sourcing logic. Treating 30gsm floating row cover the same way you treat a framed frost tent is how returns begin.

This article is the Frost Cover sourcing decision hub. At every point that needs depth, we link to a dedicated deep-dive—materials science, scenario selection, quality control, packaging and logistics, and real sourcing cases. What you get here is a decision framework, not an encyclopedia.

Who Needs Frost Cover—and Which Decision Matters Most

Garden centre autumn displays. Nursery overwintering crops. E-commerce seller return rates. Frost cover shows up in all of these, but each scenario needs a different product.

If you source autumn and winter plant protection for any of these channels, start by figuring out which type of frost cover you actually need.

Garden centres stock frost fleece as a seasonal SKU alongside bulbs, garlic, and autumn planting supplies. Nurseries need bulk rolls to protect their own crops. Distributors need full-range coverage for different customer demands. E-commerce sellers need lightweight, low-return SKUs. Hardware stores need peg-hook display packs. Professional growers need large-area coverage and reusability.

But here is the decision fork most buyers miss: which type of frost cover are you buying?

Type	Also Known As	Structure	Key Sourcing Parameters
Flat-lay fleece	Garden fleece, frost fleece, floating row cover	No frame; laid directly over plants	GSM, roll width, length
Plant jacket	Plant jacket, frost bag	Bag-style with drawstring or zip closure	Height × width, closure type, GSM
Framed frost cover	Framed frost cover, frost tent	Steel/fibreglass frame + cover + zip door	Tube diameter/wall thickness, cover material, vents
Pop-up frost cover	Pop-up frost cover	Spring wire frame, folds flat	Folded/expanded dimensions, spring durability

This classification is not an academic exercise. Flat fleece sourcing revolves around GSM and UV stabilisers; framed products carry their biggest risk in tube wall thickness and zip quality; jackets hinge on size matching and closure type. Get this wrong, and your inspection checklist is wrong from day one.

That is why the four-type framework exists.

If you need to consolidate different types from different factories into one container—that is exactly what we do every day.

Buyer and Channel Scenarios

Channel differences in frost cover are not just about price. Garden centres need peg-hole packs, nurseries need bulk rolls, e-commerce needs lightweight low-return items—same 30gsm fleece, three entirely different sourcing logics.

Garden Centre: Pre-autumn bulk orders, needs retail packaging and barcodes. 30gsm rolls are the core SKU—2×5m retails around £5–7, 8×1.5m around £10 (based on Amazon UK at time of research; check current market prices). 50gsm jackets and framed covers fill the mid-to-upper range. Display method drives packaging—peg holes or blister cards are essential.

Nursery / Grower: Focused on value and durability. Bulk rolls (3.2m width × 100m+), 50gsm or higher, UV stabilisation is non-negotiable. No retail packaging needed—plain pack is fine. High repeat-order rate; consistency matters more than the lowest single-order price.

Distributor: Range completeness is the competitive edge. Needs 17–80gsm full range plus framed products, multi-spec mixed orders. Strong OEM demand—own brand name, own packaging design. Margin comes from spec combinations, not per-unit price.

E-commerce Seller: Lightweight, easy to ship, low return rate. 30gsm rolls and multi-size 80gsm jackets are the workhorses. Single-item pack size and weight directly affect shipping cost. Negative reviews cluster around “underweight” and “zip failure”—one e-commerce seller (based on industry feedback) listed 17gsm insect barrier fleece as “frost protection”; customers used it at -3°C, plants were damaged, and the keyword “not frost proof” in reviews dragged search rankings down, with sales declining for three months afterwards. Both issues must be caught at inspection.

Hardware Store: Seasonal display alongside multi-category autumn/winter tools. Needs peg-hook display packaging with clear product information. Short buying window, tight restock cycle.

Product Types and Key Specifications

Flat-Lay Fleece: GSM Is the Core Decision Parameter

GSM (grams per square metre) determines insulation level, tear resistance, and service life. It is the single most important number when you source fleece.

Tier	GSM	Protection Level	Expected Life	Market Positioning
Good	17–25	Light frost + insect barrier; short spring use	1 season	Entry
Better	30	Standard frost protection—market’s best-selling spec	1–2 seasons	Mainstream
Best	50–80	Heavy frost + overwintering protection	2–3 seasons	Premium

30gsm is the dominant spec on Amazon UK, where 2×5m packs are the standard retail format. But note—30gsm is the supplier’s stated value, not a measured value. GSM overstatement is the biggest trust risk in fleece sourcing. A product labelled 30gsm that actually weighs 25gsm performs similarly in light frost, but under -5°C or prolonged freezing, the insulation gap translates directly into returns.

Other key parameters:

Parameter	Common Range	Buyer Significance
Roll width	1.0–3.2m	Determines coverage method and cutting efficiency. 1.6m and 2.4m are the most common retail specs
Length	5–2,000m	Retail 5–10m/roll; nursery 100m+ bulk rolls
Light transmission	≥70% (30gsm)	Affects photosynthesis—higher GSM means lower transmission
UV stability	1–3 seasons	Determines reuse cycles. Fleece without UV stabiliser becomes brittle after one winter

A UK garden centre purchasing manager told us that, in their experience, around 70% of frost cover returns come from zip failures on framed products—not from the fleece itself. That is why framed product sourcing parameters are far more complex than fleece.

But if your customers need something they can walk into—a structure, not just a sheet—the parameters change completely. Frame strength, zip quality, and ventilation become the decision drivers.

Parameter	Common Range	Buyer Significance
Tube diameter	16–25mm (steel)	Determines wind resistance. 16mm is insufficient in exposed areas
Tube wall thickness	0.5–1.0mm	0.5mm is the floor; below this, the deformation risk in wind is high
Frame material	Galvanised steel/powder-coated steel/fibreglass	Galvanised steel resists corrosion; powder coat looks good but can scratch; fibreglass is light but less strong than steel
Connection type	Bolts/clips/push-fit	Bolts are most stable; plastic clips embrittle in cold—a common failure point
Ventilation	Zip window/flip lid/none	Products without vents cause heat and moisture build-up on sunny days—plant rot
Anchoring method	Ground pegs/weight bags/rope	Pegs that are too soft bend—this is a high-frequency installation complaint

Materials, Manufacturing, and Good/Better/Best Positioning

Cover Material: PP Spunbond Nonwoven

The core material in frost cover is PP spunbond nonwoven (Polypropylene Spunbond Nonwoven). Production flow: PP granules → extrusion and melting → spinning → air drawing → web formation → thermal calendering → winding → slitting → packaging.

Two points in this process are most vulnerable to cost-cutting:

1. Raw material selection: 100% virgin PP vs. recycled PP or mixed material. Recycled material costs 15–25% less (industry experience estimate), but delivers inconsistent strength, visual differences, and batch-to-batch quality swings. It is hard to tell by appearance—you need to measure actual GSM and tensile strength at the sample stage. PP itself is not on the SVHC list, but UV stabilisers and other additives may be—request a REACH SVHC declaration from your supplier, or arrange third-party testing.

2. UV stabilisers: Additive cost is roughly 5–10% of total cost (industry experience estimate), but the difference is completely invisible. Fleece without UV stabiliser becomes brittle and tears after one outdoor season; with UV, it can last 2–3 seasons. This is the “invisible but most quality-critical” variable in fleece sourcing.

Tier	Raw Material	UV Treatment	Expected Life	Cost Difference
Entry	Recycled PP or mixed	None	Degrades in 1 season	Baseline
Mainstream	100% virgin PP	Basic UV	1–2 seasons	+15–25% (estimate)
Premium	100% virgin PP + additives	Enhanced UV	2–3 seasons	+30–50% (estimate)

Put simply: entry tier drives traffic, mainstream drives repeat orders, and premium drives reputation. Your channel determines which tier you choose. If you run a garden centre, start with mainstream 30gsm as your core SKU and add premium jackets as an upsell. If you sell online, mainstream is your floor—entry tier without UV stabiliser is a return risk you cannot afford.

Frame Materials

Material	Advantages	Disadvantages	Best For
Galvanised steel tube	High strength, corrosion-resistant	Heavier, higher cost	Large fixed frost tents
Powder-coated steel tube	Good appearance, corrosion-resistant	A coating can scratch	Retail frost tents
Fibreglass rod	Lightweight, flexible	Less strength than steel	Small/pop-up types
Spring steel wire	Foldable, compact storage	Fatigue from repeated folding	Pop-up types

Most Vulnerable Components—Your Inspection Priorities

1. Zips: Repeated opening + cold embrittlement → jamming/breakage. The top complaint on framed products.
2. Stitching: Wind stress → thread breakage → cover separates from frame.
3. Connectors: Plastic clips embrittle in cold → snap.
4. Ground pegs: Material too soft → bend/pull out.
5. Cover material: UV degradation → brittleness → tearing.

Quality Risks and Test Plan

Four product types, four different quality risk profiles.

Flat Fleece: Tearing and GSM Overstatement

Tearing is one of the main return drivers for fleece. Causal chain: underweight → low tear resistance → tears in wind → lost protection → plant damage → returns. Industry feedback: after a January storm, a batch of “30gsm” fleece tore across the entire order with a return rate exceeding 40%—post-incident testing showed actual GSM of only 23. At inspection, measure actual GSM (stated value ±5%), and run tensile and tear strength tests.

GSM overstatement is the biggest trust risk. A product labelled 30gsm that actually weighs 25gsm performs similarly in light frost, but under prolonged freezing, insulation falls short. Check method: sample weighing, calculate actual GSM.

Framed Products: Structural Weakness and Zip Failure

Wind collapse is one of the most serious complaints about framed products. Causal chain: thin tube walls → insufficient wind resistance → deformation/collapse in wind → cover tears → returns + negative reviews. Industry feedback: steel tubes labelled 0.6mm wall thickness actually measured 0.4mm; after one storm, the entire batch was returned. At inspection, measure tube wall thickness and run weighted wind resistance tests.

Zip failure is the fatal user-experience flaw. Causal chain: low-quality zip → repeated opening + cold embrittlement → jamming/breakage → no ventilation → plants rot from heat and moisture → returns. At inspection, run repeated open-close testing (recommended: ≥500 cycles without failure).

Jackets: Size Mismatch and Closure Issues

Wrong sizing is the most common jacket problem—too tall and it will not stay on, too short and it crushes the plant. A jacket labelled “standard” that fits a 60cm pot but not a 90cm standard—this is the sizing mismatch that generates “does not fit” returns. Drawstring too tight damages branches; too loose and it blows off in the wind.

Pop-ups: Spring Fatigue and Storage Difficulty

Spring steel wire fatigues after repeated folding, deforming so it will not fully recover. Folding and storage is a high-barrier operation for end users—an end user who cannot figure out how to fold it back into the bag after one use will not reorder next season.

Test Methods Overview

Test	Method	Pass Criteria
GSM	Sample weighing	Stated value ±5% (common industry tolerance; some suppliers specify absolute ±0.5g/sm—confirm with your supplier)
Tensile strength	Strip method, longitudinal/transverse	Agree on a specific standard with the supplier
Tear strength	Elmendorf tear method	Agree on a specific standard with the supplier
Light transmission	Spectrophotometry	30gsm ≥70%
UV weathering	QUV accelerated ageing	≥50% strength retention after 500h (industry experience estimate; confirm specific standard with supplier)
Zip durability	Repeated open-close	≥500 cycles without failure
Tube wall thickness	Thickness gauge	≥0.5mm

Note: Most fleece products have no unified international standard. Test methods and conditions must be agreed upon at the inspection stage; specific values should be confirmed with your supplier.

OEM, MOQ, Packaging, Freight, Lead Times, and Sample Approval

When you put your own brand on a fleece pack, the OEM process begins—and MOQ and lead times determine your sourcing window. This section looks like a parameter table, but every number is a boundary condition for a sourcing decision.

OEM Customisation

Frost cover OEM is simpler than most garden products—because the core material (PP nonwoven) is standardised, customisation is mainly about cutting size, packaging, and branding.

Customisation	MOQ	Lead Time	Notes
Private-label tag	1,000–3,000 pcs	30–45 days	Simplest OEM
Custom size cutting	1,000–3,000 pcs	30–45 days	Cut and pack to buyer spec
Custom colour	Confirm the colour masterbatch MOQ with the supplier	45–60 days	Must confirm the colour masterbatch minimum batch
Custom packaging design	1,000–5,000 pcs	45–60 days	Includes printing + sample approval
Framed product customisation	200–500 sets	60–90 days	Includes frame production + cover + assembly

MOQ Reference

Product Type	MOQ	Notes
Nonwoven rolls	1×20GP (approx. 4,000–5,000kg)	By weight; confirm with the supplier
Finished fleece (cut + packed)	1,000–3,000 pcs	By piece count
Framed products	200–500 sets	By set count
Colour/size mixed orders	Confirm	Varies by supplier; confirm with the supplier

On mixed orders: One container might hold 30gsm rolls, 50gsm jackets, and framed frost covers—from different factories, with different lead times and different standards. That is why Scarecrow built a warehouse: we receive goods from different factories, inspect them to your standards, and consolidate them for shipment. You deal with one integrated container, not four scattered shipping notices.

Lead Times

Type	Lead Time	Notes
Stock rolls (existing specs)	10–15 days	Nonwoven rolls
Standard production	30–45 days	Cut, sew, pack
OEM custom	45–60 days	Includes sample approval + production
Framed products (standard)	60–90 days	Includes frame + cover + assembly
Framed products (deep custom)	120–180 days	Includes new tooling + special specs + assembly

Sample Approval Process

1. Buyer provides spec requirements (GSM, size, packaging, branding)
2. Supplier sends samples (typically 7–10 days)
3. Buyer approves samples—do not skip this step. Measure actual GSM, check stitching, test zips
4. The approved sample is sealed and kept as the reference baseline for bulk production
5. Bulk production
6. Pre-shipment inspection
7. Shipment

Autumn–Winter Protection Season Sourcing Calendar

Miss the July ordering window, and your frost cover shelf stays empty for the entire autumn selling season. This is not exaggeration—from order to shelf, the shortest path takes 90 days; framed products need 180 days.

Frost Cover’s target selling season is Autumn 2026 and Winter 2026–27. The B2B sourcing window is July–September 2026.

Timing	Action
July	Confirm product specs and supplier; order samples
July–August	Sample approval, seal samples, and confirm OEM packaging design
August	Bulk production starts
September	Inspection, shipment
October	Arrival, customs clearance, warehouse-in
November	On shelf—autumn frost begins

Work-back logic: Order in July → 90–150 day lead time → arrive October → on shelf November. If you are sourcing framed products, lead time may be 120–180 days—July is the last viable window.

On lead-time coordination: Frost cover SKUs are numerous and factory-spread—rolls from one factory, jackets from another, frames from a third. Scarecrow can help you work backwards from your shelf date, coordinate factory timelines across product types, and make sure every SKU hits the window. Talk to us about your sourcing calendar.

Container plants are more vulnerable—their roots are exposed to air, making them more susceptible to frost than in-ground plants. This means jacket-type products aimed at garden centres need to be in position early in autumn, because the first early frost often arrives in October.

Miss the window, and the shelf is empty.

Buyer Checklist and Reading Path

Sourcing Decision Checklist

Before you send an enquiry to any supplier, confirm you can answer these questions:

• Which type of frost cover am I sourcing? (Flat fleece/jacket/framed/pop-up—not “all of them”)
• What is the target channel? (Garden centre needs retail packaging; nursery needs bulk rolls; e-commerce needs lightweight single items)
• Does the GSM choice match the protection need? (17–25 light/30 standard/50–80 heavy)
• Is a UV stabiliser required? (Without it, expected life is only 1 season)
• Are framed product tube walls ≥0.5mm?
• Has the zip passed ≥500 open-close cycles?
• Has the sample been tested for actual GSM? (Not just the stated value)
• Have OEM packaging MOQ and lead time been confirmed?
• Has the sourcing calendar been worked back 90–150 days from the selling season?
• Has REACH compliance been confirmed? (PP nonwoven must be free of SVHC substances—the ECHA SVHC list reached 253 entries as of February 2026; request a REACH SVHC declaration from your supplier, or arrange third-party testing)

FAQ

Q: Is 30gsm fleece enough for UK winters? 
A: For most of the UK, 30gsm provides standard frost protection for autumn and mild winter conditions. If your customers are in exposed or northern areas where temperatures regularly drop below -5°C, or if they need overwintering protection, 50gsm or framed products are the safer choice. The key factor is how long the frost lasts, not just how cold it gets.

Q: How do I verify actual GSM if the supplier’s number is unreliable? 
A: Take a sample of known dimensions, weigh it on a precision scale, and calculate GSM (weight in grams ÷ area in square metres). Compare the result to the supplier’s stated value. A tolerance of ±5% is common; anything beyond that is a red flag. Keep the tested sample as your reference baseline for bulk production inspection.

Q: Can I mix different frost cover types in one container? 
A: Yes—this is common practice, especially for distributors and garden centres that need a full range. The challenge is coordination: rolls, jackets, and framed products often come from different factories with different lead times. A consolidation warehouse (like ours) can receive, inspect, and repack everything into one shipment so you deal with one container, not multiple shipping notices.

Q: What is the most common reason for frost cover returns? 
A: Two issues dominate: GSM understatement on fleece (supplier labels 30gsm, actual weight is 25gsm or less), and zip failure on framed products. Both can be caught at the pre-shipment inspection stage—that is exactly what our quality inspectors check before your container leaves.

Q: Do I need a UV stabiliser for e-commerce products? 
A: It depends on your positioning. If you are selling a single-season, budget-friendly product, a UV stabiliser may not be necessary. But if your product description mentions “reusable” or “multi-season,” a UV stabiliser is essential—fleece without a UV stabiliser becomes brittle after one winter, and that mismatch between promise and performance will show up in reviews.

Q: When is the latest I can place an order for autumn sales? 
A: For flat fleece, the latest practical order date is around mid-August (30–45 day production + 25–35 day shipping = arrival in October). For framed products, you need to order by July at the latest—lead times of 60–90 days plus shipping push arrival into October or November. Order later than that, and you are relying on air freight or missing the season entirely.
