Perforated Decorative Metal Sheet

Perforated decorative metal sheet is manufactured by stamping solid metal plates with round, square, slotted, hexagonal or custom decorative perforations. It is widely applied to wall cladding, ceiling boards, balcony screens, railing infill, cabinet inserts and building facade decoration. Aluminum sheets are preferred for ceilings and exterior sunshade screens thanks to low weight. Grade 304 stainless steel matches general indoor decorative projects requiring easy cleaning, while 316 stainless steel is selected for coastal or persistently humid environments. Galvanized and carbon steel substrates normally undergo powder coating after cutting and bending. These perforated sheets are delivered as flat blanks, cut-to-size panels or bent formed components following project drawings.
