01 · PANORAMICA DEL PRODOTTO

Q235B checker plates carry a raised diamond pattern rolled directly into a hot-rolled carbon steel base. The pattern provides dependable anti-slip friction even when wet, oily or dusty, while the Q235B base keeps full structural strength for load-bearing floors and steps.

WHY CHOOSE Q235B CHECKER

Un materiale, un grado: solo Q235B. Uniform diamond pattern, consistent base thickness, weldable and cuttable, with mill certificates on every batch.
