Mendoza is one of the highest hail-frequency corridors on earth — netting there is infrastructure, not insurance. 45–50 gsm for stonefruit and berries, 50–60 for table grapes and apples, ordered 9–13 weeks ahead.
Mendoza sits in one of the highest hail-frequency corridors on the planet, and Chile’s Central Valley packs a huge share of the world’s table-grape and blueberry exports into the same latitudes. For growers and distributors in Argentina and Chile, anti-hail netting is not an insurance afterthought — it is standard orchard infrastructure, spec’d crop by crop and structure by structure. The short version: 45–50 gsm for stonefruit and berries, 50–60 gsm for table grapes and apples, panels cut to the block, ordered against the October–March storm window. Here is the regional spec.
Most hail markets buy netting after a bad season. The Andes corridor buys it because hail is a near-annual certainty: the storm cells that form against the mountains give Mendoza, San Juan and the Chilean Central Valley some of the most reliable hail exposure in commercial horticulture. Three consequences for buyers. First, netting is a capital line, not an experiment — orchards structure whole blocks for it from the start, with posts and wire designed around the net. Second, the buying unit is the hectare, not the roll — orders come as panel layouts for named blocks, which is why we cut panels to dimensions rather than shipping generic rolls. Third, the season is fixed: storms run October through March, peaking December to February, so procurement lands in winter and early spring — and a container that misses the window protects next year, not this one.
The grade decision follows the fruit and the structure, and our Argentine and Chilean orders cluster into a clear pattern:
| Crop | Typical spec | Why |
|---|---|---|
| Stonefruit (peach, plum, nectarine — Mendoza, San Juan) | 45–50 gsm | Seasonal panels on standard spans; light grades handle fast during a short window |
| Table grapes (Chilean Central Valley, pergola) | 50–60 gsm | Overhead drape on pergola structures carries wider spans and picking traffic |
| Apples & pears (Río Negro, Maule) | 50–60 gsm | Permanent or semi-permanent structures that stay up through the season |
| Cherries (high-value blocks both sides of the Andes) | 55–60 gsm | The highest-value fruit specs the strongest grade — one storm pays for the difference |
| Blueberries (Chilean south-central) | 45–50 gsm | Often combined with bird netting in the same program — one structure, two duties |
Every grade ships in 100% virgin HDPE with UV stabilization, 3–8 mm mesh, reinforced edges and knitted-in eyelets — the fixing points are where hail nets fail, so the edge is built as part of the knit, not sewn on after. Full grade logic is in the hail net GSM and mesh guide.
The structure decides the panel spec as much as the crop does. Mendoza orchards typically run post-and-wire overhead structures over stonefruit and pome blocks — panels are rectangular, tensioned flat, and sized to the bay between post rows. Chilean table grapes grow on pergolas, and the net drapes over the whole pergola roof — wider panels, more slack for the vine canopy, and reinforced edges because pickers work under and around the fabric for weeks. Blueberry programs usually combine a lighter overhead hail panel with bird-duty side netting on the same posts. When you send an inquiry, the three details that let us spec the panel correctly are block dimensions, post spacing and whether the net stays up year-round or comes off after harvest.
The math that drives this region’s buying is worth stating plainly because it explains the order sizes we see. Export fruit in this corridor sells by the kilo into premium programs — cherries and table grapes at the top of that scale. A single storm cell over an unprotected block does not just cut yield; it strips the export grade off the fruit that survives, turning premium cartons into juice or domestic-market fruit in one afternoon. Against that, a 40’HQ of hail netting covers on the order of 23–33 hectares and, at 5–8 years of service life, works out to a few seasons’ protection for the price of a fraction of one hectare’s export grade loss. Growers in the corridor do not evaluate netting as a cost line against profit — they evaluate the uninsured block as the risk position. That is also why the region’s distributors stock deep: their customers do not comparison-shop in October, they buy whoever has the panel on the yard.
The logistics pattern for the region is routine for us: MOQ 2 tons with mixed panel sizes, grades and even product lines in one container — blueberry programs routinely mix hail and bird netting in the same shipment, and distributors stock stonefruit and grape specs side by side. Production runs 25–35 days after deposit, ocean freight 4–6 weeks to San Antonio, Valparaíso or Buenos Aires, and the net clears customs as a standard industrial textile. For the December–February storm peak, the order-backward count from our hail net order timing guide applies directly: 9–13 weeks from deposit to protected orchard, which puts the order date for an early-December installation in late August or September.
OMB Textiles is a knitted HDPE netting manufacturer in Changzhou, China — founded in 2003, supplying anti-hail, bird and insect netting to orchard contractors, cooperatives and distributors across Europe, the Americas and Oceania. For Argentine and Chilean programs we cut panels to your block layout: 45/50/60 gsm, 3–8 mm mesh, reinforced edges with knitted eyelets, service life 5–8 years depending on grade and exposure. A 40’HQ carries 14–15 tons — roughly 23–33 hectares of orchard canopy at hail-net weights. Samples are free, you cover the courier. Send your crop, block dimensions, structure type and destination port via the contact page or WhatsApp — we reply within 24 hours with a panel layout and the latest order date that makes your storm window. The full spec range is on the anti-hail net product page.
50–60 gsm. Pergola drapes carry wider spans and weeks of picking traffic, so the mid-to-heavy grades with reinforced edges are the standard — 45 gsm is reserved for light seasonal panels on short spans.
No — knitted HDPE with a proper UV package shrugs off normal storms and keeps working for 5–8 years. Inspect after exceptional events: replace panels where impact points have torn, not the whole block.
Pergola drapes are cut wider than the row to allow canopy slack — typically the row width plus drape allowance on both sides. Send your pergola width and post spacing and we cut to the structure; single panels can run the full row length.
Count backward 9–13 weeks: 25–35 days production, 4–6 weeks freight, 1–2 weeks installation. Early-December installation means ordering by late August or September; orders placed in October typically land for the back half of the storm season.
Yes — mixed-product containers are standard for the region. Blueberry programs especially combine a 45–50 gsm hail panel with bird netting in one 2-ton-minimum shipment, each product with its own labels and packing.
