Structural Steel Strip Coil Suppliers – Strength You Can Count On

Structural steel is the backbone of modern construction, infrastructure, and heavy equipment. And when it comes to getting the job done right, structural steel strip coils offer a perfect combination of strength, formability, and reliability. These coils are hot rolled and then slit into narrow widths, making them ideal for framing, supports, and custom-fabricated components.

At Midwest Steel Supply, we specialize in supplying structural-grade strip coils to fabricators, OEMs, and builders across the U.S. Whether you need large truckload shipments or smaller cut-to-order volumes, our inventory is built to serve you quickly and consistently.

What Makes Our Structural Strip Coils Stand Out?

• Consistent Thickness & Width Tolerance: Precision-slit coils mean better fit and reduced waste during fabrication.

• Certified Material: All coils come with full mill test reports meeting ASTM and AISC standards.

• Custom Processing Options: We slit, cut-to-length, and package based on your specs.

• High-Strength Grades Available: From A36 to A572 and A992, we stock grades used in everything from warehouse construction to bridge building.

Our steel strip coils are ideal for structural shapes, stiffeners, base plates, bracing components, and even general industrial uses. Available in thicknesses ranging from 3mm to 16mm and widths up to 2000mm.

Applications Across Industries

• Structural columns and framing systems

• Cross-members and support beams

• Building trusses and walkways

• Manufacturing jigs, racks, and platforms

• Agricultural and construction equipment

We work closely with engineering firms, contractors, and manufacturers to ensure every order meets project specs and timelines.

HR Coils for Shipbuilding Industry – Built to Endure the Sea

Shipbuilding is a tough business. The materials must handle pressure, movement, and corrosion for decades. That’s why hot rolled (HR) coils remain the top material choice in shipyards around the globe. Their durability, weldability, and formability make them perfect for the complex structures of modern vessels.

At Midwest Steel Supply, we provide marine-grade hot rolled coilshttps://midweststeelsupply.org/product/hot-rolled-steel-strip-coils/ that meet strict global standards. These coils are ideal for everything from hull plating to deck structures, offering long-lasting performance even in extreme marine environments.

Why HR Coils Are Best for Shipbuilding

• Formability: Easy to bend, cut, and roll for curved and custom ship shapes.

• Strength: High yield strength to handle constant stress and load conditions.

• Corrosion Resistance: Available with pickled and oiled finishes or marine-grade coatings.

• Thicker Gauges: Offered in heavy thicknesses for structural integrity in hulls and frameworks.

Popular Grades We Offer

• A36 (ASTM) – A standard structural steel used extensively in marine and offshore applications.

• S275JR / S355JR – European standards with strong mechanical performance.

• Q235B / Q345B – Chinese GB equivalents offering excellent workability and strength.

We also support third-party inspections and provide full material traceability and mill test reports on all orders.
