Galvanized perforated sheet is a practical and aesthetically pleasing metal material widely used in construction, machinery, decoration, transportation, and other fields. It is made from steel or other metal sheets and undergoes a galvanizing process to enhance its corrosion resistance and prolong its service life. The "perforated" aspect refers to holes punched into the sheet, serving both functional and decorative purposes.
 
1. Common Specifications
1. Sheet Thickness:
Galvanized perforated sheets typically range from 0.5mm to 8mm in thickness. Popular options include 1.0mm, 1.5mm, 2.0mm, and 3.0mm. Thinner sheets are suited for decorative or lightweight applications, while thicker sheets are ideal for structural or load-bearing uses.
 
2. Hole Diameter and Pitch:
Hole diameters vary from 1mm to 20mm. The pitch (distance between hole centers) can be customized. Common combinations include 1mm/1mm, 2mm/2mm, and 5mm/3mm. A wide variety of hole shapes is available—round, square, oblong, hexagonal, etc.—to meet ventilation, light transmission, and aesthetic needs.

3. Sheet Dimensions:
Standard sheet sizes include 1000mm × 2000mm and 1219mm × 2438mm. Custom sizes are available, up to 1500mm in width and 4000mm in length.
 
4. Zinc Coating Thickness:
Zinc coating thickness affects the corrosion resistance of the perforated metal. Standard coating ranges from 30g/m² to 275g/m². For indoor use, light galvanization is sufficient; for outdoor or harsh environments, heavy galvanization is recommended.

2. Customization Options
To meet specific project requirements, galvanized perforated sheets can be customized in several ways:
 
1. Size Customization:
Sheets can be cut into custom shapes and sizes, such as rectangles, circles, and other forms based on design needs.
 
2. Hole Shape Customization:
Beyond standard shapes, you can choose star, cross, plum blossom, fish scale, louver shapes, and more to create a unique visual effect.
 
3. Surface Finishing:
Different surface treatments are available, such as powder coating, spray painting, or electrophoresis, to improve corrosion resistance and appearance.

3. Applications
Galvanized perforated sheets are highly versatile and used in a wide range of industries:
 
Architectural Decoration:
Used in facades, ceilings, partitions, and railings—offering both style and function.
 
Mechanical Equipment:
Commonly used as protective covers, filters, ventilation panels, and more.
 
Transportation Infrastructure:
Ideal for highway and railway noise barriers and anti-glare panels, improving safety.
 
Agriculture & Food Processing:
Applied in grain screening, drying systems, and ventilation to enhance productivity.
 
Furniture Manufacturing:
Modern furniture often incorporates perforated metal in chair backs, cabinet doors, etc., for added aesthetics.
