Tianjin BRISK STEEL focus on produce and supply hollow section and steel pipe

Our EN 10219 S355J0H square steel tube cover a wide range of sizes to meet diverse project needs, with detailed specifications as follows:

• Standard: EN 10219 (Cold formed welded structural hollow sections of non-alloy and fine grain steels)

• Material Grade: S355J0H

• Size Range: Square section: 15×15mm - 1200×1200mm; Wall thickness: 1.3mm - 50mm (customizable according to customer requirements)

• Length: Common lengths: 6m, 12m; Customizable length: 3m - 18m as per client needs

• Dimensional Tolerances: Outside dimension: ±1% with a minimum of ±0.5mm; Wall thickness: ±10% for t≤5mm, ±0.5mm for t>5mm; Squareness of side: 90°±1°; Straightness: 0.15% of total length; Mass tolerance: ±6% on individual length

• Surface Treatment: Black (self-colored uncoated), varnish/oil coating, pre-galvanized, hot-dip galvanized (optional, to enhance corrosion resistance)

S355J0H grade is renowned for its high strength and excellent low-temperature performance, making it suitable for harsh working environments. The core mechanical properties comply with EN 10219 standards:

• Minimum Yield Strength (Reh): 355 N/mm² (345 N/mm² for specific sizes)

• Tensile Strength (Rm): 510 - 680 N/mm² (490 - 630 N/mm² for specific sizes)

• Elongation (A): Minimum 20%

• Impact Toughness: J0 grade, meeting impact energy requirements at 0℃ (usually ≥27J), ensuring no brittle fracture in low-temperature environments

• Weldability: Excellent weldability with low carbon equivalent (Ceq ≤ 0.45), suitable for various welding methods without preheating, ensuring stable joint quality

• Packaging: Products are bundled with steel straps, with plastic caps on both ends to prevent damage during transportation; anti-corrosion treatment (varnish, anti-rust oil) is available as required, and packaging can be customized according to customer needs.

• Shipping: We have an efficient global logistics network, supporting FOB, CIF, CFR and other trade terms; products can be shipped to major ports around the world, with professional logistics teams to ensure safe and timely delivery.

• Standard Compliance: All products are strictly manufactured in line with EN 10219 standards, with CE marking, PED approval, and mill test certificates (MTC) provided to ensure compliance with global quality requirements.

• High Quality & Precision: Adopting advanced cold-forming technology, the products have uniform wall thickness, smooth surface, tight dimensional accuracy, and controlled corner radius, ensuring stable performance in structural applications.

• Versatile Applications: Widely used in structural engineering (building frameworks, warehouses, stadiums, high-rises), mechanical manufacturing, bridge construction, agricultural equipment, solar power stents, and transportation infrastructure, suitable for both indoor and outdoor harsh environments.

• Sufficient Inventory & Fast Delivery: We maintain a large inventory of various sizes, enabling immediate dispatch; the monthly production capacity reaches 10,000 metric tons, with a delivery time of 30 days against deposit or L/C at sight, ensuring on-time supply for your projects.

• Customization Service: We provide custom cut-to-length, size customization, and surface treatment services according to customer requirements, reducing on-site fabrication time and improving construction efficiency.
