Premium Quality Hot-Rolled Mild Steel Sheet & Galvanized Coils

Our Premium Quality Hot-Rolled Mild Steel Sheet Coils and Galvanized Steel Coils are manufactured to meet the most demanding industrial, automotive, and structural applications worldwide. Designed in strict compliance with international standards such as ASTM A653, EN10327, and JIS G3302, these steel coils deliver exceptional mechanical strength, superior formability, and reliable welding performance.

With an extensive material grade range—from commercial quality (Q195, Q235, Q345) to structural galvanized hot-rolled coils (SGHC) and cold-rolled equivalents (SGCC, DX51D)—we provide a highly versatile raw material solution. Whether you require thick hot-rolled mild steel plates or heavily zinc-coated galvanized coils for extreme outdoor environments, our factory ensures precise dimensional tolerances and flawless surface finishes to optimize your downstream manufacturing processes.

Key Advantages

Heavy-Duty Corrosion Resistance: Our galvanized coils feature a highly uniform zinc layer, customizable from 40 g/m² up to a massive 375 g/m². This guarantees decades of rust protection for outdoor infrastructure, heavy-duty vehicles, and high-tension towers.
High Precision & Strict Tolerance: We enforce rigorous quality control across our continuous casting and rolling lines, achieving a strict thickness tolerance of +/- 5%. This extreme precision prevents material jamming and wastage during your automated stamping or roll-forming processes.
Comprehensive Mill Processing Services: Beyond supplying raw steel coils, we act as your first-step manufacturing partner. We offer in-house value-added services including precision decoiling, cutting-to-length, bending, and welding, delivering ready-to-use materials directly to your assembly line.
Verified Export Reliability: With over 15 years of export experience and robust OEM capabilities, we understand international standards intimately. We provide comprehensive Mill Test Certificates (MTC) to guarantee the chemical and physical properties of every coil shipped.

Product Applications

The exceptional ductility and strength of our mild steel and galvanized coils make them the foundation for numerous industries:
Construction & Infrastructure: Essential for building galvanized steel frames, highway signs, protective gears, and high-tension electrical towers.
Automotive Manufacturing: Widely stamped and formed to produce highly durable car parts, including the bodies and chassis of trucks and buses.
Home Appliances: The preferred rust-resistant raw material for manufacturing the housings of washing machines, air conditioners, hair dryers, and other white goods.
Heavy Industry & Fluid Transport: Extensively utilized in pipeline transport systems, boiler pipes, mining equipment, chemical industry components, and metal pails.

Packaging & Delivery

Standard Export Mill Packing: Coils are heavily protected for maritime transit. They are wrapped in damp-proof kraft paper, covered by steel protector sheets, and strapped tightly with high-tensile steel bands to prevent edge damage or moisture ingress.
Coil ID Compatibility: Manufactured with standard inner diameters (508mm or 610mm) to ensure they mount immediately and perfectly onto your factory’s uncoiling/decoiling machines without requiring adapters.
Optimized Freight Solutions: Due to the dense weight of steel coils (3 to 30 tons each), we optimize loading via 20ft shipping containers to maximize payload limits. For large-tonnage procurement, we efficiently arrange bulk carrier vessels.
Fast Lead Time: Backed by our 70,000-ton annual capacity, standard orders are processed and shipped rapidly, typically within 10 to 25 days after the receipt of an advance payment (T/T or L/C).

Frequently Asked Questions (FAQ)

Q: What is the Minimum Order Quantity (MOQ) for your steel coils?
A: Our MOQ is 20 Tons, which perfectly equates to one full 20ft container to ensure the most economical ocean freight rate for you. Mixed specifications within the container are acceptable.

A: Yes. We strictly produce coils with Inner Diameters (ID) of 508mm and 610mm, which are the universal standards for decoiling equipment across North America, Europe, and Asia.

A: Absolutely. As a comprehensive manufacturer, we provide secondary processing services including decoiling, cutting-to-length, and slitting. We can ship flat steel sheets instead of coils if that best suits your manufacturing setup.

A: We continuously monitor the galvanizing bath and utilize digital coating thickness gauges during the run. We guarantee the exact zinc coating weight requested, whether it’s the standard 220 g/m² or a customized heavy coating up to 375 g/m².
