S355J0WP Steel Plates for a Facade Panel Manufacturer in the Netherlands

In November, 2026, we delivered 80 tons of S355J0WP weathering steel plates to a facade panel manufacturer in the Netherlands, for a waterfront office building on the Rotterdam harbourfront.

The plates, 3 mm to 8 mm thick, are laser-cut and press-braked into cassette panels of varying widths. S355J0WP was chosen by the architect for its stable, even patina in the marine-influenced harbour atmosphere, and for its guaranteed impact properties at room temperature, which suit the cold-forming operations in the panel shop.

Before production, we agreed with the client on the copper and chromium window within the EN 10025-5 range, the surface condition (mill scale retained for a uniform weathering start), and the flatness requirement for cassette forming, because a wavy blank shows as shadow lines on a finished facade.

All heats were supplied with EN 10204 3.1 mill certificates, and the client's third-party inspector witnessed the chemical analysis at the mill. The plates were shipped in one batch to Rotterdam, packed on timber bearers with interleaving paper to protect the rolling surface.

The manufacturer reports that laser cutting and bending went without deviation, and the first panels are already on the building, starting to develop their patina. A second facade package for the same project is in quotation.

If you manufacture facade panels or architectural elements from S355J0WP or other weathering steel grades, welcome to send us your cutting list and thickness range for an offer.
