Solutions for Your Industry, Ready for Your Choice
EN 10025 is Europe's primary standard for hot-rolled structural steels (full title: *Hot rolled products of structural steels*). Its steel tubes are predominantly categorized into three main series—S235, S275, and S355—covering general-purpose, medium-strength, and high-strength structural applications; they constitute the mainstream choice for structural tubing within the engineering sectors of both Europe and the global market.
We are supplying top-quality S355JR steel products in strict accordance withEN 10025-2 European standard, with stable performance, complete certifications, and sufficient stock for urgent orders. As a widely used high-strength structural steel grade, S355JR delivers exceptional mechanical properties and reliable processability, making it the first choice for heavy engineering and industrial manufacturing.
EN 10210 S355J2H HOLLOW SECTION
Our hot finished EN 10210 steel hollow sections are produced in line with EN 10210-1 (technical requirements) and EN 10210-2 (dimensional specifications), covering round, square, rectangular, and oval cross-sections, both welded (ERW) and seamless types. Made of non-alloy and fine-grained steels, these sections are available in a full range of steel grades to meet different project demands, including S235, S275, S355, and S460 series (such as S235JRH, S275J2H, S355J2H, S355K2H, S460NH).
50×50mm steel box section, also known as square hollow section (SHS), is a widely used structural component in construction, engineering, and decoration fields. It features uniform strength distribution, excellent torsional stiffness, and easy fabrication, making it a preferred choice for architects, builders, and engineers worldwide. We provide high-quality 50×50mm steel box sections with various specifications, reliable quality, and flexible purchasing options to meet different project needs.
Hollow Structural Steel Tubes (HSS) refer to high-strength welded or seamless steel tubing with a hollow cross-section, widely used as structural elements in buildings, bridges, machinery and various manufactured products. With the advantages of high strength-to-weight ratio, excellent torsional resistance, aesthetic appearance and low maintenance cost, our HSS tubes have become the preferred choice for engineers, architects and purchasers worldwide.
Square and rectangular tubes, also known as square and rectangular hollow structural steel sections, are economical cross-section profiles made from hot-rolled or cold-rolled steel strips through cold bending, high-frequency welding, and sizing. High-precision products can also be produced using cold drawing/redrawing processes. They are one of the most widely used profiles in modern steel structures, machinery manufacturing, and construction engineering.
JIS G 3101 SS400 HOLLOW STRUCTURAL SECTION
SS400 is a general-purpose carbon structural steel under the JIS G 3101 standard, with a core advantage of 400 MPa tensile strength, good weldability/ machinability, and low cost. It is widely used in non-critical structures such as buildings, machinery, and bridges, and is the global mainstream equivalent grade to Q235B, S235JR, and A36.
ASTM A500 GR.B HOLLOW STRUCTURAL SECTION
ASTM A500 GR.B is the most commonly used cold-formed welded structural steel pipe in North America, with moderate strength, good weldability/formability, and high cost performance, widely used in construction, bridges, and mechanical structures.
