Stainless Steel Duct Fabrication

Professional stainless steel duct (SUS Duct) welding and fabrication service, producing both round and rectangular ducts customized to project specifications. Material grades include SUS304, 316, 310, 321 and more, with surface finishes ranging from 8K mirror and brushed to 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.

• Flexible Shape & Specification Customization — Stainless steel ducts are available in both round and rectangular configurations. We custom-manufacture ducts in various shapes, specifications, and plate thicknesses according to project-specific requirements. Whether standard dimensions or non-standard custom specifications, we deliver products that precisely meet your technical requirements.

• Comprehensive Material Grade Selection — Our stainless steel ducts are available in a wide range of material grades including SUS304, 316, 303, 310, 310S, 301, 302, 304L, 316L, 321, 201, 202, 902, 904, 317, 430 and more. We recommend the optimal material grade based on operating environment and media characteristics, ensuring long-term stable performance under various working conditions.

• Diverse Surface Finish Options — We offer extensive surface treatment options including 8K mirror finish, colored stainless steel, matte finish, brushed finish, patterned finish, etched finish, titanium gold, snowflake sand, 2B, BA, and industrial heavy plate finishes. Each finish type addresses different requirements for aesthetics, corrosion resistance, and functionality in specific application environments.

• High-Airtightness Welding Technology — Professional welding processes including argon arc welding and plasma welding ensure superior airtightness. Our stainless steel ducts are suitable for systems with stringent airtightness requirements, including process exhaust, solvent exhaust, organic exhaust, waste gas exhaust (outdoor sections), humid heat exhaust, and smoke extraction systems. Every product undergoes rigorous airtightness testing before delivery.
