Your Trusted Supplier for High-Strength Structural Steel
Safety and structural integrity are non-negotiable in construction and heavy manufacturing. As a leading steel processor and distributor since 1998, Runfei Steel Group supplies premium structural grade steel capable of withstanding massive static and dynamic loads. Backed by our 300,000-ton annual processing capacity in Tianjin, we provide high-yield and high-tensile steel materials that offer excellent forming and welding properties. Every structural plate and coil we deliver is fully certified with Mill Test Reports (MTR) to guarantee chemical composition and mechanical performance.
Versatile Structural Grade Applications
We inventory and process specialized structural steel tailored for the world’s most critical industries:
-
Bridge & Infrastructure Steel: High-strength, low-alloy (HSLA) plates designed to offer superior toughness and fatigue resistance, ensuring the long-term stability of highway bridges and large-span architectural structures.
-
Automobile Structure Steel: Precision cold-rolled and hot-rolled structural coils featuring excellent deep-drawing and forming capabilities, ideal for manufacturing safe, lightweight automotive chassis and frame components.
-
Heavy Machinery Construction: Robust steel plates engineered to endure the extreme stresses found in the fabrication of cranes, excavators, and heavy-duty transport trailers.
Precision Processing & Global Export
We understand that large-scale fabrication requires materials that are ready to use. Operating from our 170-acre facility in the Tianjin Hangu Industrial Park, we offer comprehensive value-added services. We can accurately slit structural coils, cut plates to specific lengths, and perform precision blanking prior to shipment. With established export logistics since 2006, we ensure your heavy structural steel is securely packaged and efficiently shipped to over 60 countries.
Frequently Asked Questions (FAQ)
Q: Do you provide Mill Test Reports (MTR) for your structural grade steel?
A: Absolutely. Complete material traceability is critical for structural engineering. We provide official Mill Test Reports with every shipment, verifying the steel’s yield strength, tensile strength, elongation, and precise chemical composition.
Q: Does your structural steel offer good weldability?
A: Yes. Our high-strength, low-alloy (HSLA) structural grades are specifically formulated with controlled carbon equivalents (CEV). This ensures excellent weldability and formability without compromising the steel’s load-bearing capacity, reducing the risk of cold cracking during fabrication.
Q: Can you process structural steel coils into custom-sized flat plates?
A: Yes. With our heavy-duty cut-to-length and leveling lines, we can process large structural steel coils into perfectly flat, custom-sized sheets and plates, saving you significant time and labor costs on your production floor.
