S355K2G1W weathering steel product technology and classification

Rust stabilization treatment method for S355K2G1W weathering steel: The rust stabilization treatment method uses a chemical method (rust liquid) to slowly melt the surface film of the S355K2G1W weathering steel to produce rust stability and form a uniform rust layer. The protective effect can suppress the rust that flows out of the weathering steel plate in the initial stage of use.

It takes at least 1 to 2 years to produce a stable and dense rust-red protective layer from a new S355K2G1W weathering steel, and it may take about 5 to 6 years for some dry areas.

Therefore, most S355K2G1W weathering steel on the market will use rust-promoting agents to accelerate the formation of rust layers, and attention should be paid to selecting appropriate rust-promoting agents and appropriate S355K2G1W weathering steel processing methods.
