Features & Benefits of Stainless Steel Perforated Sheet 1.22×2.44
- High opening rate: Opening rate can reach over 30%, with excellent air flow and light transmission.
- Light weight: Because of the high open area, perforated mesh is lighter than solid sheet of the same size.
- Corrosion resistance: Stainless steel and other alloys provide strong resistance to rust and chemical attack.
- Attractive appearance: Hole shapes and patterns can be customized to create decorative façades and interior designs.
- Easy processing: Sheets can be cut, bent, welded, rolled and further fabricated without losing integrity.
- Environmental protection: Metal perforated sheets are fully recyclable and reusable.
- Perfect filtrability: Widely used as sieves and screens for grain dryers, bee hives, wine presses, fish farming, hammer mills, window screens and industrial filters.
Stainless Perforated Sheet Hole Shapes
Available hole shapes include round, oblong, square, triangular, fish scale, bridge, diamond, pentagonal, hexagonal, octagonal, cross, nail, plum blossom, manhole, I-shape and many other custom irregular patterns.
