How to prevent the corrosion of steel structure?
Steel structure has always been favored by people, but the anti-corrosion of steel structure is a problem .The
steel structure material itself has poor corrosion resistance, heat resistance and non-refractory. If engineering
application can not properly handle steel structure anti-corrosion and Fire protection issues ,which will directly
affect the safety and durability of the project.
1. Anti-corrosion measures for steel structures
(1)Hot dip zinc anti-corrosion treatment
In the atmosphere, the zinc layer can protect the steel for a long time, and the effect is good. The general effective protection time is about 10 years.
(2)Thermal spraying treatment
The thermal spray material used for steel materials is zinc, aluminum or zinc aluminum alloy.This layer of
coating not only provides physical isolation, but also prevents electrochemical reactions from occurring and
provides double-layer protection for steel materials.
