According to the latest surveys, most perforated sheets are produced with round holes. Why? Round roles are manufactured relatively more straightforward with aesthetic effects. The circular die for the punching sheet can last longer and is easy to manufacture, making the round hole perforated sheet cheaper than any other perforated sheet with other hole patterns. Therefore, the round hole pattern becomes the most popular shape.

Applications

Round hole perforated sheet offers the most comprehensive options of hole sizes, gauges, materials and sheet size for all types of applications. For example:

• Cladding and ceiling panels.
• Sunshade and sunscreen.
• Filter to sieve seed, stone and other bulk materials.
• Decorative banister.
• Protective fences of overpasses and machine types of equipment.
• Balcony and fence panels.
• Ventilation sheet, such as air-condition grilles.

The 316 Stainless Steel perforated Sheet sunshades and claddings can provide privacy for the building occupants without any view obstruction. Meanwhile, it features control of interior climate to reduce the air condition load and save energy to a large extent. Perforated fences and banisters secure the safety of people and keep enclosed machines and other properties from damage.

Round hole perforated sheet Hole pattern:

There are three ways of arrangements of round holes are adopted: straight type, 60° staggered type and 45° staggered type as shown in the following picture:

Generally, the 60° staggered type is the strongest, most versatile one with high cost-effectiveness.
