Alloy and temper decide what an extruded profile can actually carry, and the difference between grades is larger than most specifications acknowledge. A 6063-T5 profile offers around 145 MPa yield strength with an excellent surface for anodizing, while 6061-T6 reaches roughly 240 MPa and suits load-bearing structures where appearance matters less. Buyers ordering from an Indonesia aluminum factory can select the grade against the duty rather than accepting whatever the stockist holds. Across all grades, aluminum weighs about a third of steel and forms its own corrosion-resistant oxide layer, so protection is built into the material before any coating is applied.
PT Exalum Metal Indo extrudes at Tangerang, Indonesia, serving industrial and architectural customers in domestic and export markets. The catalog of Exalummetal industrial aluminum products is indexed by section number, a fixed profile that repeats identically on reorder, which is what allows a manufacturer to hold assembly tolerances across separate production batches. Here are the six profiles that account for most industrial demand.
1. Flat Bar
Flat bar is the general-purpose stock cut into machine bases, mounting strips, structural straps, and electrical busbar work. Section 10026 is 20 mm by 3 mm at 0.163 kg per metre, and section 10033 is a solid 25 mm by 10 mm at 0.678 kg per metre. Because the cross-section is solid, drilling, tapping, and countersinking proceed without the wall collapse risk thin hollow shapes present under the same tooling.
2. Heatsink
Heatsink profiles carry heat away from inverters, amplifiers, LED housings, and base station equipment, using fin density to multiply the surface exposed to airflow. Section 96004 runs a 1.00 mm wall at 0.378 kg per metre, and section 96001 carries 1.25 mm fins at 0.799 kg per metre where thermal duty runs continuously. Tight tolerances keep the base flat against component plates, since even small gaps degrade transfer. Section details are listed on the Exalum product pages.
3. Unequal Channel
Unequal channel caps and retains panel edges while allowing travel on one axis, common in partition tracks, furniture capping, and light framing. Section 32052 is 38.10 mm across the web with a 25.40 mm flange in a 0.90 mm wall, 0.212 kg per metre. The differing flange heights let the concealed side take fasteners while the visible side stays narrow, which two folded sheet parts would otherwise have to achieve between them.
4. Rectangular Hollow
Rectangular hollow section keeps a frame square under off-centre load, which open sections cannot do as well, suiting gates, machine guards, display systems, and canopy framing. Section 45082 is 23.50 by 12.40 mm in a 0.80 mm wall at 0.150 kg per metre, and section 45204 is structural at 100 by 50 mm in a 2.50 mm wall, 1.962 kg per metre. Porthole extrusion closes the box without a seam, so there is no weld line to inspect or fail.
5. Conveyor Profile
Conveyor profile, called T-slot extrusion in North America, gives a bolted modular frame in place of welded steel. Section 70360 is a double-slot rail at 1.20 mm wall, 1.095 kg per metre, and section 70015 is heavier at 2.50 mm wall, 1.764 kg per metre. Pre-anodised and cut to length, the rail is ready straight off the saw, and accessories from gussets to panel gaskets drop into the same slots.
6. Equal Angle
Equal angle reinforces any 90-degree junction, from structural gussets to shelving brackets and corner guards in high-traffic plants. Section 20047 has a 19 mm leg at 1.00 mm wall, 0.100 kg per metre, while section 20043 steps up to an 18 mm leg at 2.00 mm wall, 0.184 kg per metre. Extruded from a single billet, the corner radius holds consistent grain rather than the residual stress a press brake leaves in a folded bend.
Standard profiles remain the efficient choice for industrial supply because the dies exist, quotations carry no tooling development, and dimensions stay consistent run after run. Matching profile, alloy, and finish to the application at design stage avoids rework later.
