Rust Grade — Definition and Commercial Application

What are rust grades for steel? Grades A, B, C, and D explained — how they are assessed, how they affect shot blasting, and the difference between rust grade and blast cleanliness grade.

Turning a rust-grade observation into a useful project brief

A rust grade is a description of the initial steel condition, not a scope, price, method or finish specification. Photographs, accessible faces, old coatings, corrosion extent, repairs, access, working-area constraints and the intended next coating stage help turn the observation into a practical commercial discussion.
