What Specifications Should Be Considered for Perforated Metal Panels in Engineering Projects?

Perforated Metal Panel Specifications for Engineering Projects

For engineering and construction projects, selecting the correct perforated metal panel specifications is essential for structural performance, installation efficiency, and long-term durability.
Improper specification selection often leads to on-site modification, increased cost, and project delays.

This guide highlights the key specification factors engineering procurement teams should consider.

1. Material Selection

Material choice depends on application environment and budget:

• Aluminum perforated panels: lightweight, corrosion-resistant, widely used for building facades and exterior screens

• Galvanized steel perforated metal: cost-effective for industrial and utility projects

• Stainless steel (SS304 / SS316): suitable for harsh or high-humidity environments

Material selection directly affects panel weight, lifespan, and overall project cost.

2. Panel Thickness

Thickness is a critical specification for engineering projects.
Common thickness ranges include:

• 1.5–2.0mm for interior and low-load applications

• 2.5–3.0mm for exterior facades and screening systems

• 3.5–4.0mm for large panels or high wind-load areas

Thickness selection should consider panel size, fixing method, and wind load requirements.

3. Perforation Pattern and Hole Size

Perforation pattern influences both performance and appearance:

• Round holes are most commonly used due to balanced strength and uniform look

• Larger hole sizes improve ventilation and light transmission

• Smaller hole sizes provide better visual screening

Engineering projects usually prioritize structural stability and open area control over decorative complexity.

4. Panel Size and Edge Treatment

Panel dimensions affect fabrication and installation:

• Larger panels reduce joints but require higher rigidity

• Folded edges or reinforced frames improve panel strength

• Edge treatment should match the selected installation system

Early coordination of panel size and edge detail helps avoid installation issues.

5. Installation Method Consideration

Specification selection should always align with installation method, such as:

• Frame-mounted systems

• Folded-edge cassette panels

• Direct bolt-fixed installation

Installation requirements influence thickness, hole pattern layout, and edge treatment.

Specification Coordination Leads to Faster Quotation

When specifications are clearly defined, suppliers can:

• Optimize material usage

• Recommend suitable thickness and patterns

• Provide a fast and accurate quotation

Clear specifications reduce revisions and accelerate procurement decisions.
