Our factory is equipped with a large-scale automated cold rolling production line, employing a six-roll precision rolling process and continuous annealing temperature control technology to precisely control the thickness tolerance of the sheet metal (±0.02–±0.10mm). This ensures that the sheet metal surface is smooth, free of cracks, folds, and oxidation defects, with regular dimensions and high straightness, making it highly adaptable to subsequent welding, stamping, and painting processes. We also have ample production capacity and sufficient stock, enabling fast delivery of standard specifications within 5–10 days. Futures orders are efficiently scheduled for production, with delivery completed within 10–20 days. Leveraging the advantages of major departure ports such as Shanghai, Tianjin, and Qingdao, we optimize container allocation solutions to reduce shipping costs and ensure that orders are delivered to customers on time and with high quality.

Packaging Standards
Inner Packaging: Moisture-proof paper + plastic film
Outer Packaging: Galvanized iron corner protectors + steel strapping
Labels: Grade, Specifications, Roll Number, Gross Weight, Net Weight, Place of Origin, Standards
Payment Methods
Flexible payment terms available: T/T and L/C. For new clients, 30% advance payment for production, balance against copy of B/L. L/C is acceptable for large & regular orders to secure both parties.
Warehousing Management
Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.
All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.
Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.
Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.
Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.
We will provide full reception services to support the customers' on-site inspection of the goods.
Warehousing Management
A ten-thousand-ton standardized warehouse with grid-based zoning and system positioning enables rapid material retrieval and reduces the time spent searching for materials.
Inbound inspection: Verify the physical items against the inbound form, inspect the appearance, dimensions, and labels. Once confirmed to be correct, the materials are entered into the ERP system and processed for storage.
Logistics and Global Delivery: Self-operated fleet + contracted logistics partners; expedited service available for urgent orders.
International Shipping: Supports FOB, CIF, DDP, and other trade terms, covering 100+ countries and regions.
Process: Booking → Trucking → Customs Declaration → Loading onto Ship/Aircraft → Bill of Lading Issuance → Document Delivery → Destination Port Customs Clearance (Optional) → Last-Mile Delivery.
Provides door-to-door one-stop logistics with full tracking to ensure safe and timely arrival of goods.
After-Sales Service and Traceability: Delivery receipts, logistics information, and quality inspection documents are sent to customers within 24 hours of shipment.
Established a full product lifecycle traceability system, allowing tracking of production, quality inspection, warehousing, and transportation records.
