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.

Built to Outlast Your Crops – 25+ Years of Proven Service Life
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.
The Science of Sacrificial Protection – Why Pre-Galvanized Wins
Unlike post-fabrication galvanizing that misses internal surfaces and cut edges, our process dips the steel strip before roll-forming. The result:
● Complete Internal & External Coverage: No hidden corrosion starting points.
● Self-Healing Edge Protection: Zinc naturally corrodes before steel, even at cut ends.
● Fertilizer & Chemical Resistance: Withstands ammonia, nitrates, and humidity without accelerated degradation.
Backed by China's Top 500 Manufacturing Powerhouse
