Perforated Metal Specifications and Custom Options
| Specification | Available Options | Why It Matters |
| Material | Carbon steel, galvanized steel, stainless steel, aluminum and other confirmed materials | Affects strength, weight, corrosion resistance and cost |
| Sheet Thickness | Customized according to material and application | Determines rigidity, weight and fabrication feasibility |
| Hole Shape | Round, square, slotted, hexagonal or custom patterns | Affects airflow, filtration, appearance and strength |
| Hole Size | Produced according to drawings or application requirements | Determines particle passage, visibility and ventilation |
| Hole Arrangement | Straight, staggered or custom layout | Influences open area and visual effect |
| Open Area | Customized according to airflow, light or filtration needs | Affects ventilation, weight and structural performance |
| Sheet or Panel Size | Standard or cut-to-size sheets and panels | Supports installation and reduces secondary processing |
| Solid Margins | With or without unperforated borders | Helps with framing, fastening and panel installation |
| Surface Finish | Mill finish, galvanized, painted, powder-coated or other confirmed finishes | Improves appearance and corrosion resistance |
| Additional Fabrication | Cutting, bending, forming, welding or edge treatment | Allows delivery of installation-ready parts |
Choose the Right Hole Pattern and Open Area
Round Hole Perforated Metal
A versatile option for ventilation, filtration, acoustic control, screening and architectural panels. Round holes can be arranged in straight or staggered patterns.
Square Hole Perforated Metal
Provides a clean, linear appearance and is commonly used for machine guards, screens, partitions and decorative applications.
Slotted Hole Perforated Metal
Suitable for directional airflow, drainage, material separation and applications requiring an elongated opening.
Hexagonal Hole Perforated Metal
Offers a distinctive appearance and can provide a relatively high open area for ventilation, light transmission and decorative use.
Custom Perforated Patterns
Custom hole shapes, spacing, margins and decorative layouts can be manufactured according to drawings and production feasibility.
Perforated Metal vs. Expanded Metal: What Are the Key Differences?
Perforated metal and expanded metal are both produced from metal sheets, but they differ in manufacturing method, structure, weight, and typical applications.
Perforated metal is manufactured by punching or laser-cutting round, square, slotted, hexagonal, or custom holes into a solid sheet. It retains the original sheet thickness and provides consistent openings, a flat surface, and precise open-area control. These characteristics make custom perforated metal suitable for filtration, ventilation, acoustic control, screening, and decorative applications.
Expanded metal is produced by simultaneously slitting and stretching a metal sheet into a raised or flattened diamond-shaped pattern. Because no material is punched away, it offers a strong, lightweight, and slip-resistant structure commonly used for walkways, stair treads, machine guards, platforms, and security screens.
Choose perforated metal when precise hole patterns, controlled airflow, or a smooth appearance are required. Expanded metal is generally more suitable for load-bearing, anti-slip, and protective applications. Buyers can explore both product categories through our wire mesh wholesale supply range.
Why Are Perforated Metal Panels Used in Architectural Design?
Perforated metal panels combine visual flexibility with practical functions, making them suitable for building facades, ceilings, sunshades, partitions, railings, canopies, and decorative screens.
Round, square, slotted, hexagonal, and custom hole patterns allow architects to control transparency, light, airflow, and visual effects. Hole size, spacing, open area, sheet thickness, and panel dimensions can also be customized to meet different design and performance requirements.
Materials such as aluminum, galvanized steel, and stainless steel perforated sheet provide options for different environments. Stainless steel offers strong corrosion resistance, while aluminum is lightweight and suitable for large facade or ceiling installations.
As a professional perforated metal supplier, Yangzhe can manufacture panels according to drawings, required hole patterns, dimensions, finishes, and installation needs for indoor and outdoor architectural projects.
