Bulk ordering changes what counts as a good profile. At single-container volumes, a fractional difference in wall thickness translates into real freight weight, and a section that drifts between batches turns into rework on the assembly floor. Buyers placing volume orders with Indonesia extruded aluminum manufactures are effectively buying repeatability as much as metal, since a die that has already run produces the same cross-section on the tenth order as on the first. Aluminum keeps the freight side sensible too, weighing roughly a third of steel for equivalent sections.

PT Exalum Metal Indo extrudes at Tangerang, Indonesia, supplying industrial and architectural customers in domestic and export markets. The catalog of Exalummetal industrial aluminum products lists every profile by section number, a fixed reference that does not change between orders, with 6-metre standard lengths and cut-to-size, square-ended, deburred options for buyers who prefer finished pieces on arrival. Here are the six profiles that make up most bulk industrial demand.

1. Conveyor Profile

Conveyor profile, or T-slot extrusion, gives a modular frame bolted through continuous slots instead of welded. Section 70360 is a double-slot rail at 1.20 mm wall, 1.095 kg per metre, and section 70010 is a single-slot rail at 2.15 mm wall, 1.589 kg per metre. For an integrator building the same workstation repeatedly, buying the rail in bulk and cutting in-house is usually cheaper than ordering cut lengths per project.

2. Unequal Channel

Unequal channel edges and retains panels while allowing travel on one axis, common in partition track, furniture capping, and glazed screens. Section 32042 is 50.80 mm deep against a 12.70 mm web in a 0.90 mm wall, 0.182 kg per metre. At 0.182 kg per metre it ships light, which matters when a container is filled with 6-metre lengths rather than finished assemblies.

3. Flat Bar

Flat bar is the stock every fabrication shop consumes steadily, cut into brackets, spacers, machine bases, and reinforcement. Section 10032 is 25 mm by 0.90 mm at 0.062 kg per metre, and section 10064 is 44.45 mm by 1.59 mm at 0.191 kg per metre. Ordering thin sections in bulk suits shops that cut to length as jobs arrive, since extruded bar arrives square and deburred rather than needing edge dressing like sheared strip.

4. Rectangular Hollow

Rectangular hollow section stays square under off-centre load where an open profile would twist, suiting guarding, gates, display systems, and equipment frames. Section 45092 is 25.40 by 12.70 mm in a 0.90 mm wall at 0.180 kg per metre, and section 45150 is 50 by 25 mm in a 1.20 mm wall, 0.470 kg per metre. The closed box has no welded seam, so bulk stock can sit in a rack for months without a joint line to check before use.

5. Heatsink

Heatsink profiles remove thermal load from LED drivers, inverters, amplifiers, and network hardware. Section 96010 runs a 1.00 mm wall at 0.313 kg per metre, and section 96001 carries 1.25 mm fins at 0.799 kg per metre for heavier continuous duty. Buyers producing electronics in volume often hold one or two fin profiles in stock and machine the base per model. Full section details are on the Exalum product pages.

6. Equal Angle

Equal angle handles corner bracing and edge protection across rack frames, signage structures, and machine guards. Section 20025 has 12.70 mm legs at 0.80 mm wall, 0.053 kg per metre, and section 20048 is heavier at a 19.05 mm leg with a 2.00 mm wall, 0.196 kg per metre. Across a bulk order the wall choice compounds, so specifying to the actual bracket load rather than one blanket size measurably reduces shipped weight.

Standard sections suit volume buying because the tooling is already proven, lead times stay short, and dimensions hold across repeat containers. Which profile fits depends on load, fabrication method, and the finish the end application requires.
