Custom Processing Options
Project-specific processing reviewed against your drawings
Processing options can be coordinated through selected in-house production or partner factories, subject to project requirements and confirmation; staggered, straight and custom patterns reviewed per drawing.
Processing options can be coordinated through selected in-house production or partner factories, subject to project requirements and confirmation; sheet sizes reviewed against CAD drawings.
Processing options can be coordinated through selected in-house production or partner factories, subject to project requirements and confirmation; forming, notching and rolling reviewed per project.
Hot-dip galvanizing, powder coating, anodizing, and electropolishing options can be coordinated upon request.

Frequently asked questions
Find technical answers on alloy selection, lead times, and custom fabrication specs.
We supply products in carbon steel (hot-rolled and cold-rolled), 304 and 316 grade stainless steel, and 3003-H14/5052-H32 aluminum alloys. Galvanized, electro-polished, and powder-coated surface treatments can be arranged upon request.
Have custom specs?
Technical supportSend your mechanical drawings, custom perforation patterns, or bar grating schedules directly to our team.
Quote timing and lead times are confirmed per project
Material documentation (such as mill test reports) can be requested at quotation; availability depends on the product and the producing factory.
Need help with a specification?
Send your material gauges, hole patterns, drawings, or standards references for your project. Our team reviews them and supplies perforated metal, expanded metal, bar grating, and checkered plate to your specification through selected in-house production and partner factories.
Drawings, hole patterns, and material parameters reviewed by our team.
Industry standards (ASTM, EN, GB, ISO, NAAMM) serve as benchmark references.
Material test reports available on request, depending on product and producing factory.
