304 Stainless Steel Square and Rectangular Pipes

Our 304 Stainless Steel Square and Rectangular Pipes are premium austenitic stainless steel hollow sections manufactured to the highest quality standards. With the classic 18% chromium and 8% nickel composition, 304 stainless steel offers exceptional corrosion resistance, excellent formability, and superior weldability—making it the most versatile and widely specified stainless steel grade for industrial, commercial, and architectural applications.Manufactured through precision cold-forming and TIG welding processes, these square (SHS) and rectangular (RHS) pipes feature a smooth, uniform surface finish that meets the most demanding aesthetic and functional requirements.Available in a comprehensive range of surface finishes—mill finish, brushed (180–400 grit), mirror polished (#4, #6, #8), hairline, satin, and pickled & passivated—our 304 stainless steel square and rectangular pipes deliver outstanding performance in corrosive environments, food processing facilities, marine applications, and architectural projects.
