Considerations for use of Cor-Ten and weathering steels

Considerations for use of Cor-Ten and weathering steels:

1.The actual corrosion loss varies with the environment. For long-life, corrosion allowance must be considered.

2.Crevices and water/dirt traps should be avoided

3.Rust stains may run to adjacent surfaces and cause staining

4.Fasteners should be made of weathering steel

5.Specific low alloy welding rods should be used

6.For an even weathering result, surface blasting may be necessary

7.Weathering steels are unsuitable for use in marine and aggressive industrial environments
