Standards Compliance
Our galvanized round tubes meet the most stringent European and American standards — specifically EN 10240 and ASTM A53. Every batch is certified to these specifications, ensuring your wholesale clients receive products they can trust.
Surface Treatment
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 demonstrated a lifespan of up to 5,000 hours without showing any rust — most factory-made tubes only last 3,000 hours.
Manufacturing Process
- Cold-drawn forming: Computer-controlled machines form steel into round tubes with diameter tolerances of just ±0.1mm — every tube in a batch is identical.
- Pickling: Tubes are pickled to remove rust and scale, ensuring secure adhesion of the subsequent zinc coating.
- Hot-dip galvanizing: Each tube is immersed in a 450°C zinc bath to create the durable protective coating.
- Thickness inspection: Each tube inspected with a magnetic thickness gauge to ensure minimum zinc coating of 275 g/m². Non-conforming tubes are rejected.
- Precision cutting: Laser cutter cuts tubes to desired length (1–6m) with ±0.5mm accuracy.
- Pressure testing: Each batch pressure-tested at 1.6 MPa to check for leaks before packaging.
