S355 Low Carbon Steel

S355 Structural Steel: High-Performance Solutions for Modern Engineering

S355 Low Carbon Steel

S355 is a versatile, low-carbon mild steel recognized for its superior strength-to-weight ratio. Delivered in its hot-rolled state, this grade is engineered to provide a minimum yield strength of 355 N/mm², making it the preferred choice for projects that require durability without excessive bulk.

Certified Quality Assurance

At Progressive Metal Manufacturing, we prioritize structural integrity and transparency. To ensure your project meets the highest industrial safety standards, all our S355 low-carbon steel inventory is fully traceable. Customers can request comprehensive Cast and Analysis certificates or BS EN 10204 3.1 mill certificates at the point of order. These documents verify the chemical composition and mechanical properties of the steel, providing the peace of mind required for high-stakes engineering.
