Common grades include 304, 316, 316L, and 321. Pipes and plates together serve petrochemical, food processing, and construction applications. Source both from Congbang for streamlined procurement.
Angle bars provide structural support alongside stainless steel plates in construction projects. Available in 304, 316, and 316L grades, angle bars complement plates for frames and supports. Used in building structures, industrial equipment, and architectural applications. Combine plates with angle bars for complete structural solutions.
Custom stainless steel processing from customer drawings, including cutting, bending, forming, and welding. Equipped with advanced thermal cutting equipment such as plasma cutting, laser cutting, and waterjet cutting, along with leveling, slitting, and surface treatment facilities. Covering both cold and hot rolling processes to meet diverse industrial requirements for custom stainless steel components.
Professional stainless steel duct (SUS Duct) welding and fabrication service, producing both round and rectangular ducts. Custom-manufactured in various shapes, specifications, and plate materials according to project requirements. Material grades include SUS304, 316, 310, 321 and more. Surface finishes include 8K mirror, brushed, matte, and colored stainless steel. With excellent corrosion resistance, heat resistance, and airtightness, our ducts serve process exhaust, solvent exhaust, organic waste gas, humid heat exhaust, and smoke extraction systems.
Professional stainless steel plate mirror finish processing, offering three mirror grades: 6K standard polish, 8K fine ground, and 10K ultra-fine ground mirror finish. Protective film applied after mirror processing to prevent scratches during transport and fabrication. Brightness correlates with material thickness — thinner plates achieve better mirror effects, with 10K delivering the highest luminosity. Widely used in architectural decoration, elevator interiors, appliance panels, and other applications requiring premium surface quality.
