Grating, Expanded Metal & Perforated Buying Guide
Bottom line: Open-area products must be specified by product style and opening/bearing geometry—not simply “grating” or “mesh.”
What to put on the RFQ
Product familyBar grating, expanded metal, perforated sheet, welded wire or another product.
MaterialCarbon steel, galvanized, stainless or aluminum.
Opening / patternMesh, diamond, hole diameter, pitch or bearing-bar spacing.
Thickness / bar sizeSheet thickness or bearing/cross-bar dimensions.
Panel sizeRequired width, length and quantity.
Finish / load needCoating plus any project load or slip-resistance requirement.
How to avoid buying the wrong material
Start with the project drawing, approved material specification or actual service conditions rather than a generic product name. Dimensions, grade/specification, finish, length, quantity, processing, certifications and delivery requirements can all change what should be quoted.
For replacement or maintenance material, photos and measurements help, but markings, mill certifications, original drawings or manufacturer information are stronger evidence when available.
Send a cleaner RFQ
Attach the drawing, cut list or material takeoff whenever possible. Include delivery ZIP and required date so sourcing and freight can be evaluated.
