6 Aluminum Extrusion Products From a Leading Aluminum Manufacturer in Indonesia
Extrusion can produce shapes that no other forming process delivers economically. Pushing a heated billet through a steel die makes internal cavities, undercut slots, and dense fin arrays in a single pass, where steel would need those features cut, folded, and welded from separate pieces. That capability is the practical reason manufacturers buy finished profiles from an Indonesia aluminum factory rather than fabricating equivalents locally. The material helps too, weighing around one-third of steel and forming a protective oxide layer without galvanizing.
PT Exalum Metal Indo operates its extrusion plant in Tangerang, Indonesia, supplying industrial and architectural buyers domestically and for export. The range of Exalummetal industrial aluminum products is organised by section number, a fixed profile reference that stays identical on every reorder, so a frame extruded this year still accepts brackets cut from last year’s stock. Standard lengths are 6 metres, with cut-to-size and deburred ends on request. Below are the six profiles that cover most of what leaves the factory for industrial use.
1. Conveyor Profile
Conveyor profile, or T-slot extrusion, replaces welded frames with a system bolted through continuous slots. Section 70330 is a single-slot rail at 1.20 mm wall, 0.647 kg per metre, and section 70480 is a double-slot rail at 1.35 mm wall, 2.014 kg per metre for high-density automation mounting. Guarding panels seat directly into the slots with gaskets, so an enclosure can be added or reconfigured without touching the frame with a drill.
2. Equal Angle
Equal angle braces corners and shields edges across rack framing, machine guards, tile edging, and support brackets. Section 20025 has 12.70 mm legs at 0.80 mm wall, 0.053 kg per metre, and section 20046 carries a 19 mm leg at 1.20 mm wall, 0.120 kg per metre. Stock sizes range from 20 by 20 mm to 100 by 100 mm, and because the angle is extruded rather than folded, the corner has no work-hardened bend line running its length.
3. Rectangular Hollow
Rectangular hollow section resists torsion across its enclosed area, which open profiles cannot match under off-centre load. Section 45150 is 50 by 25 mm in a 1.20 mm wall at 0.470 kg per metre, and section 45144 is 40 by 20 mm in a much heavier 3.00 mm wall, 0.877 kg per metre. The small external radii on the corners help coating and anodizing cover evenly, a detail that shows up on facade and guarding work where finish quality is inspected.
4. Flat Bar
Flat bar is the first stock a fabrication shop cuts for brackets, spacers, machine bases, and reinforcement. Section 10038 is 25.40 mm by 1.59 mm at 0.109 kg per metre; section 10065 is far heavier at 60 mm by 6 mm, 0.976 kg per metre. How the bar is oriented changes what it can carry, since standing it on the narrow edge increases bending resistance dramatically over laying it flat, a point worth confirming before a bracket is detailed.
5. Unequal Channel
Unequal channel retains panel edges and guides sliding components, working as track for partitions, cabinet doors, and glazed screens. Section 31021 is compact at a 15.20 mm web and 9.10 mm flange in a 1.00 mm wall, 0.085 kg per metre. The uneven flanges are a design decision rather than a limitation, giving fastener depth behind the panel while keeping the visible edge slim.
6. Heatsink
Heatsink profiles move thermal load away from power electronics, LED lighting, and telecom hardware by exposing dense fin surface to airflow. Section 96009 runs a 1.00 mm wall at 0.577 kg per metre, and section 96002 is heavier at 1.20 mm wall, 1.021 kg per metre. Fin geometry comes in straight, flared, and serrated forms depending on the airflow available; the full section list sits on the Exalum product pages.
Standard profiles hold their place in volume manufacturing because the tooling is already proven, procurement moves faster, and every run matches the last. Which section fits depends on load, orientation, downstream fabrication, and the finish the application requires.
