ASTM A1085 Gr.A HOLLOW STRUCTURAL SECTION
ASTM A1085 is a standard specifically for cold-formed welded carbon steel hollow structural sections (HSS), with only a single unified steel grade (Grade A). Its core features are a controlled yield strength range of 345–485 MPa, clear impact toughness requirements, and strict dimensional tolerances, designed specifically for seismic, bridge, and other dynamically loaded structures.
BS EN 10210 S275J0H Structural Box Section
EN 10210 S275J0H (Material No. 1.0149) is a non-alloy structural steel for European standard hot-formed hollow sections, featuring medium strength, good low-temperature toughness, and weldability. It is widely used in structural components in construction, machinery, energy, and other industries.
EN 10210 S275 HOT ROLLED HOLLOW SECTION
EN 10210 is a European standard covering hot-finished hollow sections of non-alloy and fine-grain steels in circular, square, rectangular, or elliptical shapes. It applies to profiles that are either hot-formed or cold-formed and heat-treatment, and it is the preferred profile for load-bearing structures such as buildings and bridges.
RIGHT CORNER HOLLOW SECTION (SHS/RHS) are structural steel tubes with precise, 90°corners (inner radius (≤1.5t or 2t), offering enhanced aesthetic, architectural, and structural advantages over rounded alternatives. Produced via laser welding or specialized forming, they provide high strength-to-weight ratios for facades, furniture, and heavy equipment.
ST 37 Mild Steel Hollow Section
ST 37.2 steel tube is a widely used, low-carbon structural steel (DIN grade 1.0037/S235JR equivalent) known for good weldability, formability, and moderate strength, used in construction, shipbuilding, automotive, and general industrial applications for fluid transport, structural components, and machinery parts, available in seamless, ERW, square, or rectangular forms.
ASTM A500 Grade B and C structural steel pipes and tubes play an indispensable role in various manufacturing fields. As a top manufacturer in China, Tianjin Brisk Metalwork Co.,Ltd's production technology covers all sizes and thicknesses of ASTM A500, including pipes and tubes. ASTM A500 Grade B and C are typically used in applications that require high strength, structural efficiency, weight reduction, and improved durability. In any situation that requires high or low temperature resistance, A500 is usually the preferred material.
EN 10219 S355JR HOLLOW SECTION
EN 10219 S355JR steel tube / EN 10219 S355JR rectangular steel tube、EN 10219 Rectangular tube、EN 10219 S355JR HOLLOW SECTION EN10219 standard is for structural hollow section pipe used for construction pipe, bridge steel pipe, foundation steel pipe.
EN 10219 S460NH Rectangular Tube
EN 10219 is the European standard for cold-formed welded hollow structural sections. S460NH is a fine-grained, normalized weathering high-strength steel under this standard, with a core yield strength of ≥460 MPa and satisfactory impact toughness at -20°C, suitable for outdoor heavy-duty structures.Applicable scenarios: Bridges, plant frameworks, offshore platforms, rail transit, heavy outdoor components, especially suitable for corrosion environments requiring no coating or low maintenance.
