Weathered Steel
DMD Weathered Steel is treated to prevent runoff and staining before it ever hits the jobsite. Here’s the guide and resources to specify DMD Weathered Steel for your project.
When weathering steel bleeds, it stains. That’s why more designers, contractors, and fabricators come to Dissimilar Metal Design than any other company for preweathered steel. Learn more about how we prevent bleeding on weathering steel.
If not properly treated, weathering steel will bleed into concrete, cladding — everything it touches. It can take years to fully stabilize — unless you speed up the process in a controlled environment.
That’s exactly what we do.
Our proprietary preweathering system accelerates patina formation after fabrication but before installation, so the steel arrives stabilized and consistent. No runoff staining your hardscapes or soaking into porous stone.
