Hollow Rectangular Section Properties
A Brighter And Cleaner Surface
The surface of the pre-galvanized hollow rectangular sections produced by Yuantai Derun is very clean and bright. This is very advantageous in the design of structures where aesthetics are required.
Light Weight
Pre-galvanized hollow rectangular sections are lightweight because they are thin and hollow. This makes them a reliable metal building material for lightweight steel structures.
Good Anti-Corrosion Ability
Pre galvanized hollow rectangular sections have good anti-corrosion ability, thanks to their surface galvanized layer, which has good anti-corrosion performance and can effectively prevent the corrosion of steel by corrosive media. This corrosion resistance is mainly due to the protective effect of the zinc layer. Zinc forms a barrier on the steel plate, effectively preventing corrosion factors from penetrating and protecting the steel from corrosion.
Satisfactory Hollow Rectangular Section Weight
At Yuantai Derun, every pre-galvanized hollow rectangular section is genuine and weighs enough. We use two ways to calculate weight: rational weight and actual weight. If you have any questions about weight, contact your account manager.
