Galvanized Oblong Long Round Hole Perforated Metal Punched Sheet Customizable

Hot-dip galvanized layer provides long-lasting anti-corrosion performance, greatly reducing maintenance frequency for outdoor applications and cutting overall project cost. Oblong long round holes deliver higher flow efficiency than round holes, ideal for drainage ditches, ventilation grilles and air exhaust systems. Low carbon steel plate owns proper hardness and impact resistance, not easy to deform during construction and installation. All punching processes are digitally controlled, guaranteeing stable quality and uniform perforation across the entire panel. Flexible customization covers all specifications, and we provide one-stop processing solutions. As source manufacturer, we offer favorable factory prices, stable production cycle and flexible MOQ for both trial small orders and large bulk engineering orders.

Production Technological Flow:

Raw material inspection → Plate flattening → CNC long hole punching → Deburring & leveling → Custom cutting/bending → Hot-dip galvanizing → Finished inspection → Waterproof packaging & shipment
