3 INCH CORTEN STEEL CHANNEL DRAIN GRATES/COVERS

Corten steel exudes a sophisticated and timeless aesthetic reminiscent of cast iron but at a significantly reduced cost.

This metal undergoes a transformative evolution over time when subjected to atmospheric conditions. Initially resembling mild steel, it progressively ages upon exposure to water, developing a self-protective brown-orange coating that matures into a stable rust-like patina after enduring elemental exposure over a span of several years. The natural aging process can be expedited through regular application of water to the surface.

Please note that the channel and linear drainage covers should be recessed by 4mm below the level of the paving to reduce possible run off and staining.

Furthermore, we offer the option to pre-age the covers using our post-rust finish, which not only establishes the desired colouration but also seals the top surface for enhanced durability.
