Produced by modern factories, we independently control the entire process from steel strip selection to welding, forming, and flaw detection. Following ASTM and DIN standards, our testing equipment ensures firm welds and accurate dimensions.
We maintain a rich stock of welded pipes, covering common calibers, wall thicknesses, and materials. Conventional specifications are ready for immediate dispatch, greatly shortening delivery cycles for urgent needs.
We support personalized customization, adjusting parameters such as length, caliber, and surface treatments (plastic coating, galvanizing) to meet specific project environments and anti-corrosion requirements.
We provide 7×24 hours multilingual support. From sample delivery to order follow-up and customs documentation, dedicated managers ensure an efficient, worry-free process for all global clients.
Our welded pipes are widely used for liquid transportation (pump wells, gas, water), construction structures (greenhouses, fence posts), curtain walls, and machinery parts.
For export steel products, we primarily use sea transportation for cost-efficiency. Small or urgent orders can be shipped via air freight or land transportation.
As a pioneering enterprise integrating modern production with global trade, we offer a diverse range of products including Seamless pipes, Square pipes, Galvanized pipes, and Steel plates. Our advanced production lines operate with strict quality control and meticulous cost calculation to serve various industrial sectors worldwide.
A: We are ISO9001, SGS, and CE certified. We conduct pre-production sample testing and a final inspection before shipment. Third-party inspections are also welcome.
A: Yes, we provide free samples to customers worldwide. While the samples are free, the customer is responsible for the express shipping costs.
A: Delivery usually takes between 15 to 45 days. This may vary depending on the order size or specific customization requirements.
A: Steel products are typically bundled. For sensitive items like stainless steel, we use moisture-proof and anti-rust materials, including plastic films and rust-proof paper.
A: We generally accept T/T (Telegraphic Transfer), L/C (Letter of Credit), and Collection (D/P, D/A). Flexible terms can be negotiated based on specific order circumstances.
A: Steel prices are subject to cyclical changes in raw material costs. We recommend consulting our team with your specific requirements (grade, size, quantity) for the most current quote.
