What should buyers confirm before sourcing expanded metal sheet?
Expanded metal sheet quotation should start with material grade, raw sheet thickness, LWO, SWO, strand width, sheet size, raised or flattened profile, surface treatment, cut-to-size or edge requirement, quantity, packing, destination port and required documents. This route is suitable for one-piece diamond mesh sheet supply for walkway, guard, ventilation, screening and architectural infill uses.
Product Overview
ANJIA supplies expanded metal sheets manufactured from one-piece metal plates through stamping and stretching, with raised and flattened profiles available for industrial screening, platform, guard, ventilation, fence infill and architectural applications. The existing specification table already covers material routes, raw sheet thickness, LWO, SWO, strand width, sheet size, raised or flattened profile and common surface treatments.
This P1 upgrade keeps the confirmed specs, FAQ, video and single product brochure intact. It adds clearer buyer-first guidance for RFQ structure, profile comparison, surface treatment selection, packing, export document support and related metal sheet routes.
Specifications
| Specification | Common options | Quotation note |
|---|---|---|
| Material | Mild steel, hot-dip galvanized steel, 304/316 stainless steel, aluminum alloy | Confirm material grade based on anti-corrosion and load-bearing requirements of the application. |

How to Specify Expanded Metal Sheet for RFQ
To specify expanded metal sheet for RFQ, send the material grade, raw sheet thickness, long way opening, short way opening, strand width, sheet width and length, raised or flattened profile, surface treatment, color if coated, cut-to-size or edge requirement, tolerance or flatness expectation, total quantity, packing method, destination port, trade terms and required document package.
Expanded metal sheet should be quoted by material grade, raw sheet thickness, long way opening, short way opening, strand width, sheet size, raised or flattened profile, surface treatment, color if coated, cut-to-size or edge requirement, tolerance or flatness expectation, packing method and destination. Buyers comparing expanded metal with perforated metal sheet should confirm whether the project needs stretched diamond openings, punched holes, ventilation, guard panels, decorative panels or platform-related sheet supply before quotation.

Please provide material, raw sheet thickness, strand width, long way & short way opening, sheet size, surface finish and order quantity.
What surface coating options are available?
Hot-dip galvanized, electro galvanized, powder coated and PVC coated are available; custom finishes can be discussed based on application.
What material grades do you supply for expanded metal?
Standard options include mild steel, galvanized steel, 304/316 stainless steel and aluminum; custom materials are acceptable.
Can you supply custom cut-to-size panels?
Yes. Custom sheet dimensions and special shape cutting are available with technical drawings or samples.
Can I get samples before placing bulk order?
Yes. Small sample pieces are available for quality and size check; freight is collected by the buyer.
