Field Notes on Galvanized Hexagonal poultry wire mesh

If you’ve ever patched a chicken run at dusk or lined a garden bed against nosy rabbits, you already know the quiet utility of mesh. Lately, I’ve been touring North China’s wire towns—Anping in particular—and the buzz around Galvanized Hexagonal poultry wire mesh is real. Costs are steady, zinc classes are getting heavier, and PVC coatings are smarter about ammonia and UV. In short: it’s no longer the commodity it used to be.

What it is (and what’s changing)

Classic reverse-twist hex netting woven from low-carbon Q195/Q235 wire, then hot-dip or electro-galvanized; optionally PVC-coated. Many customers say they’re shifting to heavier zinc—Class 3 per ASTM—because barns are harsher than they look. I guess that’s not surprising: humidity, bedding acids, and routine wash-downs add up.

Key specifications (typical)

Process and testing (the practical bits)

• Wire rod → drawing → annealing → galvanizing (hot-dip or electro) → weaving (reverse twist) → PVC coat (optional) → roll & strap → inspection.
• Testing: zinc mass by ASTM A90; salt spray by ASTM B117 (typical 240–480 h no red rust on Class 3); aperture tolerance checks; adhesion bend test.
• Certifications: ISO 9001 (factory QMS). Material traceability available on request.

Where it’s used

Yes, chicken and rabbit cages. Also: garden fencing, stucco backing, small animal enclosures, orchard tree guards, light-duty slope netting, and—surprisingly—craft displays at weekend markets. One contractor told me PVC-coated Galvanized Hexagonal poultry wire mesh outlasted painted panels under sprinklers by years.

Quick case notes

Hebei mid-size poultry farm swapped to Class 3 zinc 1" aperture Galvanized Hexagonal poultry wire mesh. After 18 months of wash-down cycles, lab coupons still passed 480 h ASTM B117 with only white rust. Another: a coastal landscape crew picked PVC black; 2-year field check shows no cracking, slight chalking only.

Customization tips

For burrowing pests, go smaller aperture (1/2") and thicker wire. For coastal sites, PVC over Class 3 zinc. For stucco, 1" with firm reverse twist. And label your rolls—future you will thank present you.

Note: Specs above are typical; real-world performance depends on exposure, installation, and maintenance. Still, properly chosen Galvanized Hexagonal poultry wire mesh is a long-haul workhorse.
