Understanding Expanded Metal Sheet Stainless Steel
Stainless steel expanded metal sheets represent a versatile architectural and industrial material, combining structural integrity with functional design. These sheets undergo a precision slitting-and-stretching process, transforming solid coils into diamond-patterned mesh while maintaining 40-60% material yield efficiency. With global demand growing at 5.2% CAGR (2023-2030), manufacturers now offer grades including 304, 316, and 430 stainless steel to meet diverse environmental requirements.
Technical Superiority in Material Engineering
Advanced manufacturing techniques enable expanded metal sheets to achieve tensile strengths up to 860 MPa, outperforming traditional perforated metals by 35%. Key technical parameters:
- Surface hardness: 200-300 HV (Vickers scale)
- Thermal expansion coefficient: 16.5 µm/m·°C
- Maximum operating temperature: 850°C (continuous)
Electropolishing options reduce bacterial adhesion by 72% in food processing applications, while powder-coated variants maintain UV resistance for 15+ years in outdoor installations.
