Aluminium Flat Bar Sizes and Uses, Supplier in Singapore
What is Aluminium Flat Bar?
Aluminium flat bar is a long, rectangular piece of aluminium stock with a flat surface. Fabricators typically use it in strips or bars of different widths, thicknesses, and lengths. Because of its excellent strength‑to‑weight ratio, corrosion resistance, and workability, aluminium flat bar suits many applications from construction and signage to machinery parts and architectural detailing.
Key properties include:
- Alloy grade (e.g. 6062‑T6, 6082‑T6)
- Tensile strength (often up to ~310 MPa in certain alloys)
- Density (~2.70 g/cm³)
- Corrosion resistance, especially in humid or coastal environments (important for Singapore)
Common Uses & Examples
Construction and Architectural
Aluminium flat bars are frequently used in architectural framing, curtain wall systems, and window trims due to their clean lines, corrosion resistance, and lightweight properties. In Singapore’s residential developments such as condominiums in Bishan or mixed-use projects along Orchard Road architects often specify anodised aluminium flat bars for aesthetic finishes on façades or balcony railings. The bars can be cut, bent, or welded into custom forms for both interior and exterior applications.
Marine and Outdoor Applications
Given Singapore’s humid and coastal climate, aluminium flat bars are a preferred material for outdoor structures and marine environments. From boat ladders and gangways to signage frames and outdoor enclosures, flat bars made from 6082-T6 or 6061-T6 alloy are ideal due to their excellent resistance to corrosion. We’ve supported marine service providers in areas like West Coast and Tuas with custom-fabricated flat bars for pier structures and floating pontoons.
Industrial and Manufacturing Settings
In industrial estates like Tuas, Woodlands, and Jurong, aluminium flat bars are commonly used for equipment framing, structural supports, and automation machinery parts. Manufacturers rely on our CNC-machined flat bar components for robotic arm bases, conveyor brackets, and electrical enclosures. The precision and strength of 6061-T6 aluminium ensure high performance in demanding production environments.
Electronics and Appliances
Singapore’s electronics and tech manufacturers use aluminium flat bars for heat sinks, internal chassis structures, and mounting plates in devices such as air purifiers, smart panels, and IoT control units. We support companies in regions like Ang Mo Kio Tech Park with tight-tolerance fabrication, deburring, and anodised finishes to meet exact thermal and aesthetic requirements.
Custom Projects and Prototyping
From retail display structures in malls like ION Orchard to bespoke furniture designs by interior firms, aluminium flat bars provide a versatile material for designers and engineers. The Monster Builder often partners with design agencies and prototyping firms to produce one-off or small-batch aluminium flat bar pieces that combine strength, form, and finish for high-end applications.
In addition to flat bars, we also supply structural aluminium products like angle bars.
Aluminium Flat Bar Sizes
At The Monster Builder, we fabricate and supply aluminium flat bars in various sizes to suit structural, architectural, marine, and mechanical applications. Below are the most commonly requested sizes:
At The Monster Builder, we fabricate and supply aluminium flat bars in various sizes to suit structural, architectural, marine, and mechanical applications. Below are the most commonly requested sizes:
Standard Thickness Options (mm):
3 mm, 5 mm, 6 mm, 8 mm, 10 mm,12 mm, 16 mm, 20 mm, 25 mm, 40 mm
These thicknesses are ideal for everything from light-duty trims and brackets to heavy-duty structural frames.
Standard Width Options (mm):
12 mm, 20 mm, 25 mm, 30 mm, 40 mm, 50 mm, 75 mm, 100 mm, 150 mm
For structural or aesthetic work like window trims or cladding frames, widths of 25–100 mm are common.
Length Options:
1 metre, 3 metres, 5 metres, 6 metres (stock length)
We also custom cut aluminium flat bars to your required length (e.g. 1.2 m, 2.4 m, etc.) for minimising waste and reducing fabrication time.
Material Grades & Specifications We Work With
We handle a variety of aluminium grades and dimensions. Some examples:
- Common alloys: 6061‑T6, 6062‑T6, 6082‑T6 — strong, machinable and good corrosion resistance.
- Thickness range: from thin flat bars (~2‑3 mm) to thick bars (~40+ mm) depending on project requirement. (Competitors like TAI supply 3‑40 mm; we can match or exceed in terms of precise tolerances.)
- Width & length: custom widths (20‑100 mm or more), lengths up to several metres. We can cut, bend, or weld depending on need.
