Shell Liners
We offer many choices in design and alloys for all popular mills, ranging from traditional wave styles to step liners, classifying liners and SAG mill liners.

Trunnion Liners
Not many foundries are capable of making trunnion liners. Columbia Steel is well suited for producing trunnion liners of any size and accurately machining them in our 70,000 square foot machine shop.

End Liners and Grates
We design and produce end liners for long, troublefree service life. Our grates are made of our special H79 high-strength steel which is tougher and harder than commonly used chrome-moly steels. Our grates made of H79 experience very little slot peening so mill throughput is not compromised.
