Added SuccessfullyProduct Overview
Galvanized diamond mesh, also known as small opening expanded metal, is a precision-perforated metal sheet manufactured by creating dense, uniform small holes in thin to medium-gauge steel plate. Unlike steel grating, which relies on a load-bearing grid structure, this product focuses on precise opening geometry, flow resistance control, and protective screening. It is widely used for filtration, ventilation, machine guards, architectural decoration, and lightweight walkway applications where fine openings and consistent performance are required.
The galvanized surface provides excellent corrosion resistance, making it suitable for outdoor, humid, and industrial environments. The diamond-shaped opening pattern is formed through precision stamping, laser cutting, or chemical etching, ensuring uniform hole placement, no burrs, and excellent flatness. The material is available in carbon steel, galvanized steel, stainless steel 304 and 316, aluminum, and titanium to suit different corrosion, temperature, and weight requirements.

Manufacturing and Inspection
Manufacturing Process
Precision stamping, laser cutting, or chemical etching to ensure uniform hole placement, no burrs, and excellent flatness.
Inspection Items
Hole size and spacing, open area ratio, flatness, surface finish, and corrosion protection. Filtration-grade products require flow resistance and efficiency verification.
Typical Applications
Filtration and Screening
Filter element support, fine screening, liquid and gas filtration.
Ventilation and Heat Dissipation
Equipment guards, cabinet cooling, and building ventilation.
Protection and Decoration
Guardrails, balcony panels, sound-absorbing panels, and curtain wall perforated panels.
Platforms and Walkways
Light-duty walkways and anti-slip treads, with open area and slip resistance balanced for safety.
Food and Pharmaceutical
Stainless steel 304 and 316 perforated sheets for hygienic processing and screening.
Architectural and Interior Design
Decorative facades, ceilings, room dividers, and custom perforated panels.
Selection Guide
Load-Bearing Priority
Choose steel grating when structural load capacity is the primary requirement.
Precision Flow and Protection
Choose small opening perforated metal when precise flow resistance, fine screening, or protective enclosure is required.
Environment
For coastal or humid environments, choose stainless steel 304 or 316, or galvanized steel. For high sunlight and temperature variation, avoid plastic-wood composites and prioritize metal materials.
Precision Level
For filtration and screening, select micro-perforation from 0.3mm to 1.5mm with tight tolerances. For ventilation and machine guards, standard small holes from 1mm to 3mm are suitable.
Cost Consideration
Carbon steel is the most economical option. Galvanized and stainless steel increase cost in that order. Micro-perforation requires higher processing cost.
