A long hole perforated sheet is essentially a metal sheet that features elongated holes or slots, which are created through a perforation process. These sheets are usually crafted from materials like stainless steel, aluminum, or mild steel, and they find their place in various industries where ventilation, filtration, or aesthetic appeal is needed.
The long holes not only boost airflow but also keep the structural integrity intact, making them perfect for architectural designs, air filters, security screens, and machinery enclosures. You’ll also spot them in speaker grills and decorative facades.
