Products Description

Our galvanized round tubes meet the most stringent European and American standards, specifically EN 10240 and ASTM A53.

We use hot-dip galvanizing technology, applying a minimum of 275 g/m² of zinc to each tube. Our tubes have been tested in a salt spray chamber and have demonstrated a lifespan of up to 5,000 hours without showing any rust. Most factory-made tubes only last 3,000 hours.

Factory Processing

We use cold-drawn machines to form steel into round tubes. These machines are computer-controlled, resulting in diameter tolerances of just ±0.1 mm. This means every tube in a batch is identical, making installation easier for your customers. After processing, we pickle the tubes to remove any rust or scale, ensuring a secure adhesion of the subsequent zinc coating.

Next, hot-dip galvanizing occurs: we immerse each tube in a 450°C zinc bath to create the durable coating we mentioned earlier. After galvanizing, we inspect each tube using a magnetic thickness gauge to ensure a minimum zinc coating thickness of 275 g/m². Any tube that doesn't meet our standards will be rejected-we never let unqualified product leave our factory. Finally, we use a laser cutter to cut the tubes to your desired length (from 1 to 6 meters) with an accuracy of ±0.5 mm. Each batch of galvanized round tubes is also pressure-tested-we inject 1.6 MPa of water into the tubes to check for leaks. Only after they pass all tests are they packaged.

Production Capacity

For wholesale customers, having a factory capable of handling large orders is crucial-and we have the capacity. We currently operate six fully automated galvanized round tube production lines. Each line can produce 1,000 meters of tube per day, bringing our monthly production capacity to approximately 180,000 meters.

If you need an order of 50,000 meters of steel pipe for a large customer, we can deliver it within two weeks-without waiting for material or delaying production. We also have a raw material warehouse that can hold 3,000 tons of steel coils, so we never run out of stock. We partner with a logistics company specializing in shipping to Europe and the United States and can arrange for containers to be shipped directly from our factory to your warehouse. We use an ERP system to track every order, allowing you to monitor production status at any time. Over the past two years, we've achieved an on-time delivery rate of 99.1%-we understand how crucial it is for you to receive your orders promptly. If you require custom lengths or diameters of galvanized round pipe, we can accommodate your needs-our machines can adjust sizes to produce pipes from 18mm to 1229mm in diameter.

Factory Commitment

We don't just sell galvanized round pipe-we want to build long-term relationships with our wholesale customers, so we make some solid promises.

First, we back every pipe with a three-year warranty. If any pipe rusts or leaks within three years (provided it's used correctly), we'll replace it free of charge. This warranty complies with EU consumer law, so your customers can buy from us with confidence.

Second, we promise transparent pricing with no hidden fees. We even offer a 3% discount on repeat orders-we value our loyal customers. Third, we provide 24/7 technical support. If your customers have any questions about installing galvanized round pipe or need specific dimensions, our team of engineers is just a phone call or email away. We can also send you technical data sheets and test reports to share with your customers – all the documentation they need to approve your product.
