Mild steel is a popular option with lots of our clients. Normally, mild steel is treated to prevent corrosion but we did have one client who wanted something a little different. We worked with artists Matt Donovan and Hallie Siegel and Edinburgh Printmakers to create tiny laser cut letters using mild steel. You can read more about The Rust Garden on our blog. We are able to cut all grades of mild steel up to 25.0mm thick. See other types of steel.
