Description |
| Material |
Commonly used materials include carbon steel, galvanized steel, stainless steel (such as 201, 304, 316, etc.), aluminum (1060, aluminum alloy 3003, 5005, etc.), brass, copper, etc. |
| Thickness |
Generally ranging from 0.3mm to 10.0mm. Different materials may have different common thickness ranges. For example, the common thickness of aluminum perforated plates is 0.5mm to 6mm, and the common thickness of stainless steel perforated plates is 0.5mm to 1.5mm, etc. |
| Hole Shape |
Louver holes (special elongated holes, similar in shape to louver windows) |
| Hole Size |
The size of the holes depends on specific requirements. For example, the length of the holes may be between 10mm and 50mm or even larger, and the width is around 1mm to 10mm. The specific size depends on the usage scenario and design requirements. |
| Hole Center Distance |
That is, the distance between the centers of adjacent holes, which determines the distribution density of the holes. The common hole center distance is around 10mm to 30mm, but a denser or sparser distribution can also be customized according to needs. |
| Open Area Ratio |
It refers to the ratio of the total area of the holes on the perforated plate to the total area of the plate, usually ranging from 5% to 75%. Different application scenarios have different requirements for the open area ratio. For example, the open area ratio for ventilation may be relatively high, while that for decoration or privacy protection may be relatively low. |
| Plate Size |
The width is generally less than 1600mm. The length can be in the form of coils or customized plate lengths. Common plate sizes include 1200mm×1800mm, 1200mm×2400mm, 1220mm×2440mm, 1500mm×3000mm, etc., but it can also be customized according to specific needs. |
| Surface Treatment |
Standard treatment, powder coating, spray painting, anodizing (for aluminum products), etc., to improve corrosion resistance, wear resistance, and decorative properties. |
