Perforated Aluminium Sheet Singapore

Posted on April 29, 2026 by admin | 8 Views

Perforated Aluminium Sheet Singapore is an aluminium plate that has been punched or stamped with holes in different shapes and sizes. These holes create patterns that serve both practical and decorative purposes. The sheet keeps its strength while becoming lighter and more flexible in use.

In Singapore, perforated aluminium sheet products are widely used across construction, manufacturing, and design sectors. The tropical climate here makes aluminium a smart choice because it resists rust and handles humidity well.

Why Choose Perforated Aluminium Sheet in Singapore

Singapore’s hot and humid weather demands materials that last. Aluminium forms a natural oxide layer when exposed to air. This layer protects the metal from corrosion without extra coatings . That means less maintenance and lower long-term costs.

The material is also light. This makes transport and installation easier on job sites. Workers can cut, bend, and shape perforated aluminium sheet with standard tools. It welds cleanly and holds its form over time .

Another benefit is the strength-to-weight ratio. Perforated aluminium sheet gives solid structural support without adding heavy load to buildings or equipment .

Common Alloy Grades for Perforated Aluminium Sheet

Different projects need different alloy types. Here are the main grades you will find in the Singapore market.

Grade AA1100

This is a pure aluminium grade with 99% aluminium content. It is soft, easy to form, and highly corrosion resistant. AA1100 perforated aluminium sheet works well for decorative panels, signage, and sun shades. It is not meant for heavy load-bearing jobs .

Grade AA3003

AA3003 contains manganese, which adds strength compared to AA1100. It still keeps good formability. This grade is common for roofing, wall cladding, and general fabrication work .

Grade AA5052

AA5052 has magnesium as the main alloying element. It offers higher strength and better resistance to saltwater. This makes it suitable for marine environments and outdoor structures near the coast .

Grade AA5083

AA5083 is even stronger than 5052. It performs well in harsh conditions and is often used for structural parts, transport equipment, and heavy-duty panels .

Alloy Grade	Main Element	Strength Level	Best Use
AA1100	Pure aluminium	Low	Decoration, signage, facades
AA3003	Manganese	Medium	Roofing, cladding, general use
AA5052	Magnesium	High	Marine, coastal, outdoor panels
AA5083	Magnesium	Very high	Structural, heavy-duty applications

Temper Designations Explained

The temper of a perforated aluminium sheet tells you how it was treated after rolling. This affects hardness and workability.

H14 Temper

H14 means the sheet is half-hard. It has some strength but can still be bent and shaped. This is a common temper for general fabrication .

H32 Temper

H32 is a strain-hardened and stabilized temper. It offers better strength than H14 while keeping good formability. Many structural panels use this temper .

O Temper

O temper means the metal is fully annealed. It is very soft and easy to form into complex shapes. This is ideal for deep drawing or intricate designs.

T6 Temper

T6 applies to heat-treatable alloys like 6061. The sheet is solution heat-treated and artificially aged. This gives maximum strength for load-bearing parts.

Temper	Hardness	Formability	Typical Application
O	Very soft	Excellent	Deep drawing, complex shapes
H14	Half-hard	Good	General panels, cladding
H32	Half-hard, stabilized	Good	Structural panels, marine use
T6	Very hard	Limited	Heavy structural parts

Hole Patterns and Shapes

The hole design defines both the look and function of a perforated aluminium sheet. Singapore suppliers offer many standard options.

Round Holes

Round holes are the most common type. They provide balanced airflow and a clean look. The holes can be arranged in straight lines or staggered at 60 degrees .

Square Holes

Square holes give a modern, geometric appearance. They allow more open area than round holes of the same size. This pattern suits decorative screens and ventilation panels.

Slotted Holes

Slotted holes are elongated openings. They work well for filtering, sorting, and drainage applications. The slot direction can be aligned for specific flow needs .

Hexagonal Holes

Hexagonal holes create a honeycomb effect. This pattern is popular for architectural facades and ceiling panels.

Decorative Patterns

Custom patterns include diamond, triangle, oval, and fish-scale shapes . These are often used for feature walls and artistic installations.

Hole Shape	Open Area Range	Common Use
Round	7% – 83%	Ventilation, screening, acoustics
Square	10% – 80%	Facades, decorative panels
Slotted	15% – 75%	Filtration, drainage, sorting
Hexagonal	12% – 78%	Ceilings, sunshades, cladding
Decorative	Custom	Feature walls, art installations

Standard Sheet Sizes and Thickness

Perforated aluminium sheet in Singapore follows common industrial sizes. Custom cutting is usually available.

Standard Sheet Dimensions

Most suppliers stock sheets in 4 feet by 8 feet size, which equals 1220 mm by 2440 mm . Other common sizes include 1250 mm by 2500 mm and 1500 mm by 3000 mm .

Thickness Range

Standard thickness starts from 0.5 mm for light decorative work. Heavy-duty panels can go up to 12 mm or more . Common architectural panels use 1.0 mm to 3.0 mm thickness .

Thickness Range	Typical Use
0.5 mm – 0.8 mm	Light screens, interior decoration
1.0 mm – 1.5 mm	General cladding, facades
2.0 mm – 3.0 mm	Structural panels, sunshades
4.0 mm – 12.0 mm	Heavy guards, industrial flooring

Hole Size and Pitch Details

Hole size and spacing are two key numbers when ordering perforated aluminium sheet.

Hole Diameter

For round holes, standard sizes range from 1.0 mm up to 100 mm . Small holes around 1 mm to 3 mm work for micro-perforation and acoustic panels. Medium holes from 5 mm to 12 mm suit ventilation and screening. Large holes above 20 mm are used for bold visual effects .

Pitch

Pitch means the center-to-center distance between holes. A smaller pitch packs more holes into the sheet. This increases open area but reduces material strength. A larger pitch leaves more metal between holes, adding rigidity .

Open Area

Open area is the percentage of the sheet that is hole versus metal. It ranges from about 7% for dense patterns to 83% for widely spaced holes . Higher open area means better airflow but less structural strength.

Hole Size Range	Pitch Range	Open Area	Best For
1 mm – 3 mm	2 mm – 5 mm	7% – 30%	Acoustics, fine filtration
5 mm – 12 mm	8 mm – 20 mm	30% – 60%	Ventilation, screening
15 mm – 30 mm	25 mm – 50 mm	40% – 70%	Sunshades, facades
40 mm – 100 mm	50 mm – 150 mm	50% – 83%	Bold design, light control

Surface Finishes Available

Raw aluminium has a mill finish, but many projects need extra surface treatment.

Mill Finish

This is the untreated surface straight from production. It has a natural silver look. Mill finish is the fastest and most economical option .

Anodized Finish

Anodizing uses an electrochemical process to build a hard oxide layer on the surface. This adds corrosion resistance and can be dyed in colors like black, gold, blue, or champagne . Anodized perforated aluminium sheet lasts longer in outdoor settings.

Powder-Coated Finish

Powder coating sprays dry powder onto the surface, then bakes it into a solid layer. This gives a wide color choice and strong weather resistance. It is popular for architectural projects in Singapore .

PVDF Coating

PVDF (fluorocarbon) coating offers the highest durability for exterior use. It resists UV rays, salt, and pollution. This finish is often used on high-rise building facades .

Brushed Finish

Brushed finish creates fine lines on the surface for a textured look. It hides fingerprints and scratches well. This suits interior decorative panels.

Finish Type	Durability	Color Options	Best Use
Mill	Standard	Silver only	Indoor, short-term
Anodized	High	Limited metallic tones	Outdoor, corrosion resistance
Powder-coated	Very high	Wide range	Architectural, colorful facades
PVDF	Maximum	Wide range	High-rise, coastal, extreme weather
Brushed	Medium	Silver tones	Interior decoration, feature walls

How to Choose the Right Perforated Aluminium Sheet

Picking the correct sheet depends on your project needs. Here is a simple checklist.

Step 1: Define the Function

Ask what the sheet must do. Is it for looks, airflow, filtration, or safety? This decides the hole pattern and open area.

Step 2: Select the Alloy

For indoor decoration, AA1100 is enough. For outdoor or coastal use, pick AA5052 or AA5083. For structural loads, consider higher-strength alloys .

Step 3: Pick the Thickness

Thin sheets from 0.5 mm to 1.0 mm suit light screens. Go thicker for panels that face wind, impact, or heavy handling.

Step 4: Choose the Finish

Indoor projects may use mill or powder-coated finish. Outdoor projects in Singapore should use anodized or PVDF coating for long life .

Step 5: Confirm the Size

Check if standard 1220 mm by 2440 mm sheets fit your layout. If not, ask for cut-to-size service.
