Source:www.cn-psp.cnAuthor:河北森驰公司 Last updated:2025-05-27 11:23:45 Browse:

Metal perforated sheet is widely used in architectural decoration, industrial screening, protective barriers, and more due to its unique structure and versatile performance. Depending on application requirements, these sheets come in standard stock sizes or can be fully customized. Standard perforated sheets have fixed dimensions and are ideal for general use, while custom sheets are tailored to meet specific functional or aesthetic needs.

1. Material Selection
The choice of material for metal perforated sheets varies based on usage and environmental conditions. Common options include:
 
Stainless Steel: Grades like 201, 304, 316, and 316L are commonly used due to their excellent corrosion resistance. Suitable for humid or corrosive environments.
 
Aluminum: Grades such as 1060, 3003, and 5052 offer lightweight properties and oxidation resistance. Ideal for decorative and lightweight structures.
 
Galvanized Steel: Zinc-coated for superior rust resistance, suitable for outdoor use.
 
Manganese Steel: High wear resistance makes it suitable for high-abrasion applications like screening.
 
Cold Rolled Steel: Grade Q235B with a smooth surface; allows for painting or electroplating.
 
Hot Rolled Steel: Cost-effective and wear-resistant; can be hot-dip galvanized for improved durability.
 
Copper & Titanium: Used in high-end decorative or high-temperature environments.

2. Thickness Range
Thickness varies based on the material and application of the metal perforated sheet:
 
Stainless Steel: 0.1mm – 30mm
 
Aluminum: 0.5mm – 30mm
 
Galvanized Steel: 0.2mm – 6mm
 
Manganese Steel: 3mm – 30mm
 
Cold Rolled Steel: 0.5mm – 3mm
 
Hot Rolled Steel: 1.5mm – 30mm
 
Note: Minimum hole diameter for round holes should not be less than the sheet thickness. For other hole shapes, the shortest side should not be smaller than the material thickness.

3. Hole Types and Diameters
Metal perforated sheets come in a wide variety of hole shapes:
 
Round Holes: Most common; diameter range: 0.5mm – 100mm.
 
Square Holes: Often used for decoration or protective panels.z
 
Slotted (Oblong) Holes: Ideal for ventilation and drainage.
 
Hexagonal Holes: Combine aesthetics with functionality.
 
Custom Shapes: Such as star or plum blossom shapes for decorative use.
 
Embossed Diamond Holes: Frequently used for anti-slip flooring.
 
The hole diameter impacts both the open area ratio and the mechanical strength of the sheet. Typical open areas range from 10% to 50%.

4. Hole Pitch and Layout
Hole pitch refers to the center-to-center distance between adjacent holes. It is typically equal to or greater than the hole diameter. Common layouts include:
 
60° Staggered (Hexagonal Pattern): Enhances open area and strength.
 
90° Straight (Square Pattern): Common in decorative and industrial applications.
 
Custom Layouts: Designed to meet unique design and performance requirements.

5. Sheet Dimensions
Standard dimensions vary depending on the material used:
 
Stainless Steel Sheets: 1000mm × 2000mm, 1220mm × 2440mm, 1500mm × 3000mm
 
Aluminum Sheets: Typically 1000mm × 2000mm, 1220mm × 2440mm
 
Galvanized Steel Sheets: 1000mm × 2000mm, 1250mm × 2500mm
 
Custom dimensions are available upon request to meet specific project needs.
 
6. Surface Treatment
To improve performance and aesthetics, metal perforated sheets can undergo various surface treatments:
 
Stainless Steel: Options include 2B finish, brushed, electro-polished, or mirror-polished.
 
Aluminum: Anodizing, electrophoresis coating, and powder coating available.
 
Galvanized Steel: Powder coating in a variety of colors.
 
Cold Rolled Steel: Can be painted or electroplated.
 
Hot Rolled Steel: Often hot-dip galvanized, with zinc layers up to 80μm thick.
