What is sheet metal perforation?

Sheet metal perforation is the process of creating regular holes in metal sheets, which can have different shapes, sizes and patterns. These holes are usually arranged in a predetermined pattern (e.g., in rows, passing or otherwise). Perforation is performed to give sheet metal certain functional, aesthetic or technological properties.

Perforation features:

• Shape of holes: Round, square, rectangular, hexagonal, decorative (such as irregular patterns).
• Arrangement of holes: Regular (symmetrical) or irregular, in straight or staggered rows.
• Size of holes: From very small (e.g., less than 1 mm) to large (several centimeters).
• Degree of perforation: Percentage of perforated area in the total area of the sheet.

Sheet metal perforation methods:

1. Mechanical (perforation press):
   • The most widely used method in the industry, using dies and stamps.
2. Laser:
   • It allows precise cutting of any design, especially in custom production.
3. Hydro cutting (hydro cutting):
   • Used for complex shapes and materials that are difficult to work with.
4. Chemical (digestion):
   • Mainly used for thin sheets and delicate designs.

Applications of perforated metal sheets:

1. Ventilation and permeability:
   • In ventilation, air conditioning and filtration systems.
2. Design and Architecture:
   • Building facades, acoustic screens, suspended ceilings, balustrades, decorative elements.
3. Industry and Technology:
   • Screens in machines, guards, work platforms, acoustic panels.
4. Protective applications:
   • Security grating, machine guards, burglar protection.
5. Agriculture and food industry:
   • Machine components for sorting, drying or processing products.

Thanks to perforation, sheet metal can combine lightness with strength and functionality, making it an extremely versatile material.
