Understanding 304 Stainless Steel Expanded Metal
304 stainless steel expanded metal
combines austenitic chromium-nickel alloy composition (18% Cr, 8% Ni) with diamond-pattern stretching technology. This cold-working process increases material coverage by 40-60% compared to solid sheets while maintaining 85% of original tensile strength (typically 515-720 MPa). Industrial surveys show 72% of buyers prioritize this material for outdoor applications due to its 1,500-hour salt spray resistance (ASTM B117 standard).
Technical Superiority Backed by Metrics
The material's 0.07mm/year corrosion rate outperforms carbon steel by 15:1 in marine environments. Thermal stability ranges from -200°C to 650°C, making it suitable for:
- Chemical processing equipment (pH resistance 2-12)
- Architectural sunshades (98% UV blockage)
- Food-grade conveyors (FDA Compliance 21 CFR 177.1520)

Real-World Implementation Examples
A petroleum refinery in Texas installed 2,400m² of 3mm thick expanded metal walkways, reducing slip accidents by 67% (OSHA 1910.23 compliance). In contrast, a Dutch water treatment plant utilized 0.9mm fine mesh (1.5×3mm openings) achieving 94% algae filtration efficiency.
Optimized Installation Methodology
Field tests demonstrate proper fastening (M10 bolts at 300mm intervals) increases load capacity by 40%. For curved surfaces, maximum bending radius should not exceed 8× material thickness to prevent microcracks.
304 Stainless Steel Expanded Metal's Market Leadership
Industry reports confirm 304 alloy constitutes 58% of all stainless expanded metal shipments globally. Its lifecycle cost ($0.03/year/m² maintenance) proves 28% more economical than 316L grade over 20-year periods for non-marine applications. This explains its dominant 72% market share in architectural and industrial sectors.
