We supply plates in standard mill finish or polished and treated options, with services like waterjet cutting, laser cutting, saw cutting, and custom machining.

Common Applications

Stainless steel plate offers strength, durability, and corrosion resistance across many industries:

  • Chemical Processing: Tanks, vessels, and containment systems
  • Food & Beverage: Sanitary equipment, countertops, conveyors
  • Pharmaceutical: Cleanroom walls, tables, and support surfaces
  • Marine & Offshore: Hull components, decking, and support structures
  • Energy & Power Generation: Pressure vessels, flanges, and heat exchangers
  • Construction: Architectural panels, curtain walls, structural frames
  • Transportation: Railcars, truck bodies, and protective linings

Available Stainless Steel Grades

Grade: 304 Key Properties: Versatile, corrosion-resistant, excellent formability Typical Uses: Food processing, tanks, architectural panels
Grade: 304L Key Properties: Low carbon version, easier to weld with reduced carbide precipitation Typical Uses: Welded structural components, tanks
Grade: 316 Key Properties: Superior resistance to chlorides and chemicals (molybdenum added) Typical Uses: Marine and coastal environments, chemical plants
Grade: 316L Key Properties: Low carbon for better weldability in corrosive conditions Typical Uses: Pharmaceutical, marine fabrication
Grade: 309/310 Key Properties: High-temperature resistance Typical Uses: Heat shields, furnace parts
Grade: 321 Key Properties: Stabilized with titanium to prevent intergranular corrosion Typical Uses: Aerospace, high-heat structural parts
Grade: 17-4 PH Key Properties: Precipitation-hardened, high strength and hardness Typical Uses: Aerospace, energy, and high-load applications
