Aluminum extrusion profiles from an established Indonesia extruded aluminum manufactures offer several advantages over mild steel and stainless steel in many industrial applications. Aluminum weighs roughly one-third as much as mild steel, helping reduce transportation and handling costs, while its naturally forming oxide layer provides corrosion resistance without the additional alloying elements that stainless steel requires. During extrusion, a heated aluminum billet is forced through a precision die, allowing complex cross-sections, internal cavities, and integrated fins to be produced in a single manufacturing step. Many of these features would require additional welding, forming, or machining if manufactured from steel.
PT Exalum Metal Indo has supplied Exalummetal industrial aluminum products from its extrusion facility in Indonesia for many years, serving architectural and industrial customers in domestic and international markets. The company manufactures a broad range of standard extrusion profiles with established die designs, allowing customers to reorder the same profile with consistent dimensions and repeatable quality across production runs. This consistency helps manufacturers maintain assembly-line compatibility while reducing the need for new tooling. The following are five of the most commonly specified aluminum extrusion profiles for industrial applications.
- Flat bar
Flat bar is the general-purpose stock a fabrication shop reaches for first, cut into mounting strips, machine base plates, and structural reinforcement. Around forty standard sections cover a wide range of width and thickness.
Section 10040 is 50 mm wide and 5 mm thick, 0.678 kg per metre. Section 10301, at the wider end, is 160 mm by 6 mm, 2.602 kg per metre, functioning as a lightweight structural plate without the minimum order requirements of plate stock.
- Spandrel
Spandrel profiles cover large exterior surfaces efficiently. So, it is used in cladding around loading bays, machinery enclosures, and facades where a flush, continuous surface matters. Their heavier wall construction handles incidental impacts without adding much load.
Section 62030 is 106.5 mm wide with a 9 mm return leg and 1 mm wall, 0.350 kg per metre, suited to areas that see occasional knocks during handling or use.
- Equal angle
Equal angle reinforces corners and edges wherever two surfaces meet at 90 degrees, from panel framing to protective guard edges. Sixteen sections cover a wide range of leg and wall sizes.
Section 20070 has 25.4 mm legs at 0.9 mm wall, 0.122 kg per metre. Section 20091 is more substantial, with 40 mm legs and a 4 mm wall at 0.824 kg per metre, robust enough for bracket applications without backing washers.
- Unequal channel
Unequal channel guides moving parts along one axis while retaining them on the other, most often as sliding tracks for partitions and glazed screens where space is limited but secure edge retention matters.
Section 32042 is 12.70 mm wide against a 50.80 mm depth in 0.90 mm wall, 0.182 kg per metre. That deep, narrow shape grips panel edges over long spans, something sheet metal cannot fold accurately.
- Heat sink
Heat sink profiles pull heat away from electronic components by exposing as much fin surface as possible to moving air, a role no other extruded shape fills as efficiently.
Section 96001 stands 60 mm tall and 49.9 mm wide with 1.25 mm fins, 0.799 kg per metre. Section 96003 carries slightly thicker 1.5 mm fins at 0.875 kg per metre, trading a little weight for better continuous thermal conduction.
Standard aluminum extrusion profiles remain the preferred choice for many manufacturers because they combine proven performance with faster procurement and lower tooling costs. From structural sections and architectural framing to industrial components and thermal management, these profiles support a wide range of applications while maintaining consistent dimensions across repeated production runs. Selecting the right profile depends on the application’s structural, fabrication, and finishing requirements, making early specification an important part of the design process.
