What factors are related to the galvanizing quality of Yuantai Derun square tube?

Galvanized square tubes offer corrosion resistance, decorative properties, paintability, and excellent formability. In recent years, their use in automobiles has been on the rise, becoming the primary form of automotive sheet metal. Countries around the world are researching ways to expand the variety and specifications of coated sheet metal, improve the coating process, and ultimately enhance coating quality, specifically ensuring coatability, corrosion resistance, weldability, and resistance to powdering and flaking. The quality of galvanized square tubes has always been a focus of public attention. During testing, the most important consideration is the performance of the galvanized square tubes. Factors affecting the galvanizing quality of galvanized square tubes include:

1. Operation Speed: The galvanized square tubes should be immersed as quickly as possible while ensuring the safety of the workpiece and personnel. This ensures a uniform film thickness across the entire galvanized steel tube. The lifting speed should vary depending on the tube structure, material, and length. Generally, a lifting speed of 1.5 m/min ensures good zinc reflux and surface brightness.

2. Tooling: Galvanizing tooling is very heavy during the galvanizing process.

Galvanized square tubes offer excellent strength, toughness, plasticity, and weldability, along with good ductility. Their alloy layer adheres firmly to the steel base, allowing them to be cold stamped, rolled, drawn, bent, and other forms without damaging the coating. They are also suitable for general processing, such as drilling, cutting, welding, and cold bending. The galvanized surface is bright and beautiful, allowing them to be used directly in projects as needed.
