Fabrication focused on water erosion control
We specialize in custom-fabricated grates for spillway and storm sewer erosion control. Unlike general metal shops, every grate we build is engineered specifically to stop erosion cold—designed for the exact dimensions and flow conditions of your site.
How a grate gets built
Our process starts with your site and your drainage challenge. We review your requirements, fabricate a grate to your exact specifications, and deliver a finished product built to withstand outdoor water exposure and the conditions it will face.
