Grade 1008 carbon steel perforated sheets have different holes, shapes, and patterns cut out of them that reduce weight and allow liquid and air to pass through. They have a low-carbon content, which makes them easier to weld, braze, and form than other grades of carbon steel. Typical applications include decorative structural components, sound suppression panels, filtration panels in noncorrosive environments, and barriers that provide visibility and aeration to enclosed areas.

Grade A36 perforated sheets have different holes, shapes, and patterns cut out of them that allow liquid and air to pass through. They’re strong, durable, and easy to weld and machine. They are often used for structural and architectural applications.
