304L Rectangular Tubing is a low-carbon version of the popular 304 stainless steel, manufactured as welded or seamless rectangular hollow sections (RHS). The "L" stands for "low carbon" (≤ 0.035%), which provides superior weldability and eliminates the risk of intergranular corrosion after welding. Unlike standard 304, 304L can be used in the as-welded condition without requiring post-weld heat treatment (solution annealing). This makes it the preferred choice for welded

What Is ASTM A554? ASTM A554 is the American standard for welded stainless steel mechanical tubing in round, square, and rectangular shapes. It is specifically designed for mechanical and structural applications – not for pressure service (use ASTM A269 or A312 for pressure). Square tubes under ASTM A554 are produced as cold-formed welded tubes from stainless steel strips, then heat-treated and finished to meet mechanical property requirements. The standard covers multiple

Seamless stainless steel square tubing is a hollow structural section with four equal sides and no welded seam along its length. It is manufactured by extruding a solid billet of stainless steel into a hollow tube, then forming it into a square shape.The absence of a weld seam provides superior strength, uniform wall thickness, and excellent performance under high pressure and extreme temperatures. Our seamless square tubing is ideal for critical applications where reliabilit

Stainless steel hollow section square tube is a structural profile with four equal sides and an empty interior. This design provides a high strength-to-weight ratio, making it ideal for load-bearing applications while minimizing material usage. Our hollow section square tubes are manufactured from premium stainless steel grades and are available in both welded and seamless options. They offer excellent corrosion resistance, structural integrity, and a clean, modern appearance

The Stainless Steel Welded Square Tubing is manufactured from high-quality austenitic stainless steel coils, formed into a square shape, and longitudinally welded using advanced TIG (GTAW) or ERW processes. This product offers an excellent combination of corrosion resistance, structural strength, and aesthetic appeal. Its square profile provides superior load-bearing characteristics, ease of fabrication, and clean, modern appearance, making it the preferred choice for

Stainless steel square tubing is a hollow structural section with four equal sides. It combines high strength, excellent corrosion resistance, and a clean, modern appearance. Our square tubing is manufactured from premium stainless steel grades and is suitable for structural, architectural, and industrial applications. Both welded and seamless options are available to meet different project requirements. Product Specifications Parameter Details Standard ASTM A554, A312, A269,

What Is ASTM A500? ASTM A500 is the American standard for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is the go-to specification for structural applications where strength, weldability, and economy are required. Square steel tubes under ASTM A500 are produced as cold-formed welded tubes, then heat-treated to remove internal stresses and improve mechanical properties. The standard covers four grades: A, B, C, and

S355J2H is a European standard hot-finished seamless or welded structural hollow section specified under EN 10210-2. The "S" stands for structural steel, "355" indicates minimum yield strength of 355 MPa (at 16mm thickness), "J2" denotes impact testing at -20°C, and "H" signifies hollow section. S355J2H Rectangular Tube is widely used in load-bearing structures, steel frameworks, bridges, cranes, and heavy machinery where high strength, good weldability, a

ASTM A554 stainless steel square tube is a hollow structural section with four equal sides, manufactured in accordance with the American standard for welded stainless steel mechanical tubing. This standard covers welded tubes made from stainless steel grades specifically designed for structural and mechanical applications. Our ASTM A554 square tubes offer high strength, excellent corrosion resistance, and consistent dimensional accuracy. Product Specifications Parameter
