Stainless Steel Sheet Metal Plate

Engineered for structural integrity, our CNC-machined stainless steel brackets are manufactured from grade 304/316L (ASTM A240) with ±0.1mm dimensional tolerance.

Galvalume Steel:55% aluminum-zinc alloy coated steel plate (AZ150 standard), certified by ASTM A792. The zinc-aluminum eutectic structure forms a dense protective layer, and the salt spray test life reaches 3,000 hours, which is three times that of ordinary galvanized sheets. It is applicable to photovoltaic brackets (anti-PID certification) and coastal building envelope systems, with a maintenance cycle of over 30 years. Available in 0.3-3.0mm thickness, SPCC/SECC substrates are optional.

Galvanized Steel:Hot-dip galvanized steel sheet (Z60-Z275 coating), conforming to ASTM A653 standard. The continuous annealing process (CQ/DQ/HSLA grade) is adopted, and the yield strength is 280-550 mpa. The automotive sheet has passed the IF steel ultra-deep drawing certification (r value ≥2.0), and the home appliance sheet meets the RoHS environmental protection requirements. The adhesion test of the coating (ASTM D3359) reaches grade 5B.

Aluminum Coil/Pipe/Plate:Aluminum alloy material 3003/5052/6061, in accordance with the GB/T 3880 standard. The pre-rollable coated aluminum sheet for curtain walls has passed the AAMA 2605 certification (PVDF coating ≥25μm), with a thermal conductivity of 237W/(m·K). Aviation-grade 7075-T6 pipe has a tensile strength of 572MPa and is suitable for battery trays of new energy vehicles (IP67 protection).

Stainless Steel:304/316L stainless steel (UNS S30400/S31603), conforming to ASTM A240 standard. Medical-grade 316L has passed the ISO 5832-1 certification (Ni 10-14%), with a PREN value of ≥35. Special duplex steel 2205 (S32205) combines austenitic toughness (≥40% elongation) and ferritic strength (≥620MPa).

Aluzinc Steel:Aluminum-zinc-silicon alloy coated steel plate (55Al-43.5Zn-1.5Si), in accordance with ASTM A875 standard. The thermal reflectivity is ≥80% (tested by ASTM E903), and the heat resistance temperature reaches 315℃. The special model for photovoltaic frames has passed the 2000-hour ammonia corrosion test and is suitable for power station construction in areas with high salt spray.

Prepainted Steel:HDP/PVDF coated color steel plate (film thickness 20-30μm), QUALICOAT Class 2 certification. Color difference ΔE≤1.5 (CIE Lab standard), resistant to MEK wiping ≥100 times. The antibacterial model has passed the ISO 22196 certification (antibacterial rate ≥99%) and is suitable for the enclosure system of medical clean rooms.
