Corten Steel

High-Strength Weathering Steel | ASTM A588 Grade B | Rust-Resistant Structural Plates

Corten Steel B Plates, also known as ASTM A588 Grade B Plates, are corrosion-resistant weathering steel plates with excellent strength and durability. These plates form a stable rust-like appearance when exposed to weather, protecting the surface and eliminating the need for painting. They are ideal for bridges, facades, containers, and outdoor structures.
