02 What is stainless wire used for?
Stainless wire is used for woven and welded mesh, conveyor belts, springs, fasteners, kitchen equipment, filters, braiding and architectural meshes.
03 What surface finishes are available?
Bright (cold-drawn), annealed (soft), soap-drawn, oiled and polished finishes are available.
04 What diameters are available?
Common diameters 0.1 mm to 12 mm. Custom diameters can be supplied.
05 Is 304 wire suitable for marine exposure?
For chloride or marine exposure, 316 / 316L wire is preferred due to its molybdenum content and improved pitting resistance.
