Pre-Galvanized Square Tubes are engineered to meet the growing demand for efficient, durable, and cost-effective structural materials. By applying a protective zinc coating before forming, these pipes provide enhanced corrosion resistance while maintaining excellent mechanical properties.
This makes them a preferred choice for projects where both performance and budget are critical.
These pipes are widely used in:
| Property | Description |
|---|---|
| Material Grade | Q195, Q235, Q355 |
| Surface Treatment | Pre-Galvanized (Zinc Coated) |
| Shape | Square / Rectangular |
| Length | Customizable |
| Coating Thickness | Typically 30–100 g/m² |
Pre-Galvanized Square Tubes are designed for ease of use in fabrication processes:
Manufactured by Yuantai Derun, one of China's top 500 manufacturing enterprises, these pipes are produced in facilities equipped with:
With global certifications including CE, DNV, and ABS, customers can rely on consistent quality and international compliance.
Farmers and greenhouse operators worldwide face one hidden cost: structural replacement. Tianjin Yuantai Derun's Pre-Galvanized Square Tube eliminates that expense. Our pre-galvanized RHS (Rectangular Hollow Section) is specifically engineered for humid, chemical-rich agricultural environments where untreated steel rusts within months and painted steel peels within years.
Unlike post-fabrication galvanizing that misses internal surfaces and cut edges, our process dips the steel strip before roll-forming. The result:
Yuantai Derun isn't a trading company—we're a manufacturer with 1,600 acres of facilities, 2,200+ employees, and 18 subsidiaries spanning logistics, trading, and production. Our pre-galvanized square pipes carry EU CE certification, BV inspection reports, and LEED green building credits—essential for international agricultural projects seeking sustainability certifications.
