We strictly adhere to ASTM A36, EN10025 (S235JR/S355JR), or GB/T Q235B/Q345B standards. All profiles undergo tensile and impact testing to guarantee yield and tensile strength compliance. Every shipment includes an original MTC, and we support on-site sampling and lab testing to ensure absolute structural integrity.

We commit to standard tolerance compliance (e.g., ASTM A6 or EN 10056). Our quotes clearly distinguish between "Theoretical Weight" and "Actual Weight" billing. We conduct multi-point measurements of web/flange thickness and height before dispatch, keeping tolerances within strict limits to ensure your structural calculations remain accurate.

Our profiles are processed through heavy-duty straightening machines, ensuring straightness exceeds standard requirements (e.g., curvature < 2mm/m). For 6m or 12m lengths, we perform dual-axis correction to eliminate twisting, ensuring every beam aligns perfectly on-site and significantly boosting your installation efficiency.

We offer Shot Blasting to Sa2.5 grade followed by Shop Primer coating. This prevents red rust during sea transit and provides a clean surface for immediate welding. With controlled Carbon Equivalent (CEV) levels, our steel offers excellent weldability, allowing for high-strength joints without pre-heating, reducing on-site welding defects.

We use high-strength steel strapping and can provide dedicated lifting points or slings. Inside containers or bulk holds, we employ timber dunnage for leveling and heavy-duty chain lashing for security. Edge protectors are added to flange tips to ensure that ends and wings remain straight and undamaged after weeks at sea.
