Offcut waste rarely appears in a quotation but shows up in the annual scrap figure. A plant cutting brackets from 6-metre stock will strand short ends on every length unless the section is chosen with the cut pattern in mind, which is one reason cut-to-size supply from an Indonesia extruded aluminum manufactures factory often costs less overall than buying standard lengths and cutting in-house. Extrusion supports that flexibility because the profile is continuous, so any length is as valid as another, unlike a welded steel assembly fixed at manufacture.
PT Exalum Metal Indo extrudes at its plant in Tangerang, Indonesia, supplying industrial and architectural customers domestically and for export. The catalog of Exalummetal industrial aluminum products is organised by section number, a fixed profile reference that stays constant across orders, available in 6-metre standard lengths or cut square and deburred to specification. Six profiles cover most factory requirements.
1. Unequal Channel
Unequal channel guides panels along one axis while retaining them on the other, used as sliding track, capping, and light panel framing. 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, and section 32042 is much deeper at 50.80 mm against a 12.70 mm web, 0.182 kg per metre. Extruded as one piece, the internal corners have no fold or seam that can open under repeated panel movement.
2. Flat Bar
Flat bar is the everyday stock for machine bases, mounting strips, spacers, and structural straps. Section 10022 is 12.7 mm by 0.80 mm at 0.028 kg per metre, and section 10202 is 42 mm by 11 mm with a 2.00 mm radius, 1.242 kg per metre. The spread across the catalog is what makes flat bar efficient to cut, since a shop can match the section to the part rather than machining a heavier bar down to size.
3. Equal Angle
Equal angle stiffens 90-degree junctions across rack framing, machine guards, and shelving brackets. Section 20047 has a 19 mm leg at 1.00 mm wall, 0.100 kg per metre, and section 20026 is lighter at 12.70 mm legs and 0.85 mm wall, 0.056 kg per metre. Both cut cleanly with standard shop tooling, and because the angle is extruded rather than folded, the leg stays straight after cutting instead of relaxing along an old bend line.
4. Conveyor Profile
Conveyor profile, or T-slot extrusion, gives a factory a frame system that bolts together and comes apart again. Section 70330 is a single-slot rail at 1.20 mm wall, 0.647 kg per metre, and section 70010 is heavier at 2.15 mm wall, 1.589 kg per metre for bases under mechanical stress. Offcuts stay usable here in a way welded steel offcuts do not, since any length of rail still accepts T-nuts along its full face.
5. Rectangular Hollow
Rectangular hollow section keeps a frame square under off-centre load, suiting guarding, partitions, gates, and equipment enclosures. Section 45090 is 25 by 12 mm in a 1.20 mm wall at 0.230 kg per metre, and section 45184 is 60 by 15 mm in a 1.50 mm wall with a 0.40 mm radius, 0.585 kg per metre. Porthole extrusion closes the box seamlessly, so cutting anywhere along the length exposes a clean, consistent section.
6. Heatsink
Heatsink profiles draw heat from LED drivers, power supplies, motor controllers, and network equipment. Section 96004 runs a 1.00 mm wall at 0.378 kg per metre, and section 96009 is heavier at a 1.00 mm wall, 0.577 kg per metre. Heatsink stock is usually cut to component length and machined per model, so buying in standard lengths and finishing in-house suits most electronics production. Section details are listed on the Exalum product pages.
Standard profiles stay the efficient choice for factory supply because the dies exist, lead times are short, and every run matches the last. Which section fits depends on load, orientation, cut pattern, and the finish the application needs.
