Editor’s Note: This article is part of our UV Stabilizers Guide. Visit the Hub for the full breakdown of UV protection — KLY ratings, stabilizer types (HALS vs absorbers vs carbon black), supplier verification, and 10-year cost.
UV protection has a ceiling, and yarn weight sets it. A thin, low-GSM net has too much surface area for too little material — the surface degrades faster than any stabilizer can protect, no matter how much HALS you load in. Adding more UV additive to an underweight net is like adding more paint to rotten wood. Before you compare UV grades, compare grams per square metre. Buyers who only compare price per square metre are reading half the spec.
Can adding more UV stabilizer make a thin net last longer?
No. Past a point set by yarn weight, more UV stabilizer buys almost nothing. A stabilizer protects the polymer that exists. A fine, low-denier yarn simply does not have enough material to protect — its mechanical strength is already marginal, so once UV starts thinning the surface, there is little load-bearing core left underneath. You hit a physical ceiling. The honest fix for a short-lived thin net is not more additive; it is more material.
Why does low GSM cap UV life?
It comes down to the surface-area-to-volume ratio of the yarn. UV degradation is a surface-driven process — photo-oxidation starts at the exposed skin of each filament and works inward. A thin filament has a high ratio of exposed surface to internal volume, so a larger fraction of its cross-section is “front line” at any moment. A thicker filament hides more of its mass in a protected core.
- Less material bank to lose. The same micrometres of annual surface loss remove a far larger percentage of a thin yarn’s cross-section than a thick one’s.
- Mechanical margin starts low. A light net is already near its strength limit when new; modest UV thinning pushes it past failure under wind, hail load or handling.
- The stabilizer can’t outrun the geometry. HALS slows the rate of degradation; it does not add cross-section. When there is little cross-section to begin with, slowing the rate only delays an early failure — it doesn’t prevent it.
This is why a quality UV-stabilized HDPE hail net at proper weight reaches 8–10 years in the field[1], while an underweight net carrying the same UV claim can lose mechanical integrity within a couple of seasons of strong exposure[2]. The additive grade looked the same on both. The grams did not.
Two nets, same UV grade, different weight — what changes?
| Factor | Full-weight net (higher GSM) | What the UV grade can’t tell you |
|---|---|---|
| Material per m² | More yarn cross-section to protect | UV grade is a % of additive, not a quantity of material |
| Surface-to-volume ratio | Lower — more mass in a protected core | Two nets can share a grade with very different yarn diameters |
| Mechanical margin when new | Comfortable headroom over rated load | A grade label doesn’t state tensile strength |
| Effect of surface degradation | Small % of cross-section lost per year | Same additive, but far less life on the thin net |
| Realistic field life | Matches the rated KLY band | UV grade alone over-states the thin net’s lifespan |
🧪 Kevin’s Field Notes
The most expensive sentence I hear from a buyer is “but the other quote has the same UV grade and it’s cheaper.” Nearly every time I ask for the weight, the cheaper net is lighter — sometimes close to half the grams per square metre. The UV percentage is genuinely the same; the manufacturer just put that percentage into far less yarn. It holds up beautifully in the first season, which is exactly what makes it dangerous, and then it tears in the second. I now refuse to discuss UV grade until we’ve agreed on grams per square metre first.
How do I compare nets by weight, not just price?
Ask for grams per square metre (GSM) on every quote and put it in the same table as price. Price per square metre without weight is meaningless — it can hide a 30–40% material cut behind a matching UV claim.
- Request GSM (grams/m²) for every option and list it beside price and UV grade.
- Calculate price per gram, not just per m². A “cheaper” net that is 40% lighter is often more expensive per unit of material.
- Match weight to the job and climate — permanent, high-UV, high-wind installations need more grams, not just more additive.
- Confirm the resin too. Weight and purity together form the material baseline; see our companion guide on virgin vs recycled HDPE and UV.
The two-number rule: material before additive
Settle GSM and resin first; compare UV grade second. Those are the two numbers that cap what a net can ever achieve. UV stabilizer optimises a net that already has enough sound material; it cannot create durability that the material isn’t there to support. Once weight and resin are agreed, the UV stabilizer grade and the regional KLY rating that matches your location decide the rest. For the full picture, start at our UV stabilizers hub, and see what UV stabilizers actually do in HDPE.
Frequently Asked Questions
What does GSM mean for agricultural netting?
GSM is grams per square metre — the weight of net material in a given area. It is the most direct proxy for how much yarn (and therefore mechanical and UV-life headroom) a net contains. Higher GSM at the same structure means more material to protect and more strength margin.
If two nets have the same UV rating, are they equal?
No. UV rating is a percentage of stabilizer, not a quantity of material. Two nets can share a UV grade yet differ sharply in yarn weight. The lighter one fails faster because there is less cross-section for the stabilizer to protect.
Why not just add more UV stabilizer to a light net?
Because the limit is physical, not chemical. A stabilizer slows surface degradation but adds no cross-section. A thin yarn has little material to lose before it fails mechanically, so an extra additive only delays an early failure rather than preventing it.
How much GSM do I need?
It depends on the application, climate and expected wind and hail load. Permanent, high-UV installations need more weight than seasonal, sheltered ones. Match GSM to the job first, then confirm the UV grade and KLY rating for your region.
Should I compare price per m² or per gram?
Compare both, but price per gram exposes the trick. A net that looks cheaper per square metre can be more expensive per gram of material — meaning you are paying more for less, with a shorter life to follow.

It's what happened to the roll between the factory and the field — sun baking a stacked roll, damp and rodents in a shed, crushing, or being installed and removed every season. One grower sent me photos of a "UV-failed" net where the damage stopped in a clean line down one face: the roll had sat half-out of a doorway all summer, one side in the sun, the other shaded. The net was fine; the storage wasn't.
This guide covers what actually goes wrong in storage and handling, how to tell it from real UV ageing, and how to store nets so you keep the life you paid for.

Recycled HDPE carries impurities, catalyst residue and already-broken polymer chains. Those chains soak up UV stabilizer before the sun does its damage, and they seed the cracks that show up in year two. Same label, half the field life.
This guide covers how recycled resin drains stabilizer, how to tell virgin from regrind before you order, and why we run 100% virgin HDPE on every line.
