Square & Rectangular Steel Pipes

Square tubes and rectangular tubes are steel structure tubes made of hot-rolled or cold-rolled steel strips, which are formed by high-frequency welding and hot-dip galvanized or cold-dip galvanized on the surface.

Available in a wide range of sizes, thicknesses, and surface treatments (black, galvanized, oiled, painted), our rectangular and square pipes ensure structural integrity, durability, and precise dimensions.

We supply high-quality square and rectangular hollow section pipes made from carbon steel (Q235, Q345, S275, S355) and alloy steel (20#, 45#, 16Mn, 42CrMo). Widely used in steel structure projects, machinery manufacturing, vehicle frames, and construction applications.

Product Advantages： * ✔️ Premium Material: Certified carbon & alloy steel with guaranteed strength * ✔️ Precise Dimensions: CNC-controlled manufacturing for accurate tolerances * ✔️ Excellent Weldability: Smooth surface and clean weld seam * ✔️ Surface Customization: Anti-corrosion galvanizing or coating available * ✔️ Large Stock & Fast Delivery: Regular sizes in stock for quick shipment
