Weathering steel develops a stable oxide layer that reduces maintenance painting in many outdoor designs. Buyers reference SPA-H, A588, or equivalent grades depending on the design code.
Design and ordering notes
Detailing matters: drainage, avoid crevices that hold water, and allow uniform exposure so patina forms evenly. On the purchase order, list thickness, width, length, and whether panels need pre-weathering or raw mill surface.
We supply corten plate for building and bridge components. Share your finish expectation and installation environment so we can confirm the appropriate grade and mill practice.
