Who it is for
Mesh and fencing producers, agricultural and industrial manufacturers, and distributors sourcing galvanized, Galfan or coated steel wire to a specific diameter, coating and temper.
Standards, certificates & inspection
Manufactured and tested to ASTM A641, EN 10244-2, BS EN 10218 or your customer standard. Every batch is produced under an ISO 9001 quality management system and can ship with a mill test certificate covering diameter, tensile strength and zinc-coating weight. Third-party or pre-shipment inspection (SGS, BV or customer-appointed) is available on request.
See test reports & inspection and quality control & testing for the full documentation.
Frequently asked questions
What is black annealed wire used for?
Soft, dark low-carbon wire for packing, tying, bundling and general fabrication where pliability matters more than corrosion resistance.
Is it coated?
No — it is uncoated (light oil optional). For outdoor or corrosion-exposed tying, use galvanized binding wire instead.
What sizes and packing are available?
Roughly 1.6–12.5 mm in coils or small packs; diameter, temper and pack are confirmed per order.
