Hot dip galvanized steel pipe for builders
Product Overview
Zhuozhan high-quality carbon steel pipes are designed for scaffolding, formwork support, and general structural construction. Manufactured from Q235, Q345, and Q355B grades, these pipes offer excellent yield strength (≥235–355 MPa) and superior load-bearing performance.
To ensure the long-term durability of our pipes, we offer a variety of surface treatments, including hot-dip galvanizing (zinc layer thickness ≥ 80–120 μm, providing rust protection for over 10 years), cold-dip galvanizing, and painting, giving you the flexibility to choose the best solution for your project environment.
Each pipe is manufactured under strict dimensional tolerances (outer diameter tolerance ≤ ±0.5 mm), ensuring smooth assembly with scaffolding systems such as loop, cup, and frame scaffolds. Our pipes have been proven to last 3–5 times longer than untreated pipe, helping to improve site safety while reducing overall maintenance costs.
