ASTM A36/A572 Grade ERW Carbon Iron Steel Coil for Infrastructure

YTDR Group is a trusted supplier of ASTM A36/A572 Grade ERW Carbon Iron Steel Coil, specializing in delivering high-performance structural materials tailored for global mega-infrastructure projects. Our products are engineered to meet the stringent demands of B-end clients including EPC contractors, engineering firms, procurement specialists, and distributors, with a focus on quality compliance, technical reliability, and supply chain efficiency.

Our ASTM A36/A572 Grade ERW Carbon Iron Steel Coil is specifically designed for critical infrastructure projects, serving as the core structural material for bridges, offshore platforms, high-rise building frames, highway guardrails, and power transmission towers. It is the preferred choice for clients pursuing cost-effectiveness without compromising structural integrity.

● Material Grade：ASTM A36 (low-carbon structural steel with optimal weldability and formability, yield strength ≥250MPa, tensile strength 400–550MPa) —— the most searched grade for general infrastructure; ASTM A572 (high-strength low-alloy steel, Gr 50/60/70 optional, yield strength ≥345MPa for Gr 50) —— a top choice for heavy-load projects requiring high structural rigidity. Both grades are optimized for long-term stress resistance, avoiding premature fatigue failure in harsh working conditions.

● Technology：ERW (Electric Resistance Welding) —— adopting a high-frequency induction welding process with a welding speed of 15–25m/min, ensuring uniform heat distribution at the weld seam. Unlike traditional arc welding, our ERW process eliminates slag inclusion and porosity in welds, with the weld joint strength 10–15% higher than the base metal (verified by third-party tensile tests). The precision rolling system also guarantees consistent coil flatness, reducing on-site rework costs for fabricators.

● Scope：Thickness: 0.8–12.7mm (customizable to 0.5mm for thin-gauge applications, 15mm for heavy-duty projects) | Width: 100–1500mm (max width up to 1600mm for large-area structural components) | Coil ID: 508/610mm (matching standard uncoiling equipment) | Weight: 3–25 tons/coil (adjustable to meet container loading limits, minimizing shipping costs).

YTDR Group offers flexible customization services to address the unique needs of different projects:

● Spec customization: Non-standard thickness (0.5–15mm) and width (80–1600mm) coils; special grade mixing (e.g., ASTM A36 + A572 composite coils for hybrid structures)

● Surface treatment customization: 3PE anti-corrosion coating, epoxy resin coating, or color coating according to project environmental requirements

● Processing customization: Pre-cutting to fixed lengths, edge beveling for welding convenience, threaded end processing for quick assembly

● Packaging customization: Export standard seaworthy wooden pallets, waterproof wrapping film, and rust-proof paper; marking of project numbers and specifications as required for easy on-site management.
