Most factories still default to steel, but the running costs tell a different story. Steel rusts as soon as a coating is scratched, and its weight raises freight on every container. Aluminum forms its own protective oxide skin, weighs about a third as much, and stays dimensionally stable in humid conditions. It also cuts, drills, and taps faster, shortening changeovers on the shop floor. The real advantage, though, is the process. Extrusion pushes a hot billet through a shaped die, so your factory buys the finished cross section instead of welding one up from the cut plate, and every length arrives identical.
That is where Indonesia aluminum factory PT Exalum Metal Indo comes in. Extruding aluminum for years, Exalum Metal has built its name on tight tolerances, consistent alloy, and finishes that match batch after batch. Tooling is already cut for hundreds of sections, so repeat orders come off the same dies as the first. The Exalummetal industrial aluminum products catalog runs deep, but five families do the heavy lifting on almost every shop floor.
1. Flat Bar
Flat bar is the stock you cut down whenever your factory needs a bracket, a spacer, or a plate to bolt equipment onto, which is why it outranks everything else on reorder sheets. Exalum lists roughly forty sections in this family, and a section is simply one fixed profile with its own catalog number. Section 10031 is a slim 25 mm by 3 mm strip at 0.203 kg per meter, ideal for clamp plates and packers. Section 10100 covers the heavy end at 40 mm by 8 mm with a rounded corner, 0.865 kg per meter, which suits machine base plates and mounting feet.
2. Spandrel
Spandrel closes off the gaps your facility would rather not leave exposed, covering ductwork, cable runs, and structural voids with a clean panel face. Two profiles handle most of that work. Section 62021, the lighter type, measures 100 mm wide with a 5 mm return and a 0.8 mm wall, weighing 0.248 kg per meter. Where panels take knocks from traffic or handling equipment, section 62030 spans 106.5 mm with a 9 mm return, a 1 mm wall, and 0.35 kg per meter.
3. Equal Angle
An equal angle gives your fabricators a ready made right angle, so frames get squared, edges get protected, and panels get stiffened without anyone welding a corner from scratch. Exalum tools sixteen variants of it. The lighter one, section 20047, carries a 19 mm leg and a 1 mm wall at just 0.1 kg per meter, which fits panel frames and edge guards. Section 20092 is the structural choice, with a 50 mm leg and a 4 mm wall at over 1 kg per meter, used for brackets and corner supports.
4. C Channel
C Channel or unequal channel works as a retaining track, gripping the edge of a panel, a glazed pane, or a removable cover so it stays seated without extra fixings. One profile does nearly all of it. That shape carries the code 32042, running 12.7 mm wide and 50.8 mm deep with a 0.9 mm wall, only 0.182 kg per meter. Folding that same shape from heavy gauge sheet would cost more and never hold tolerance as well.
5. Heat Sink
Heat sink extrusions pull waste heat out of drives, power supplies, and control cabinets and shed it into the air, which keeps that equipment from failing early on a production line. The workhorse type is section 96003, a profile standing 60 mm tall and 50 mm wide with thick 1.5 mm fins at 0.875 kg per meter. Its listed perimeter of 446.256 mm serves as a good proxy for dissipating surface area, and the fins are solid enough to drill and tap for mounting hardware, unlike thin fin arrays that bend on the first install.
Standardizing your stock list with one Indonesia extrusion factory keeps maintenance simple, freight predictable, and fabrication consistent across every shift and site you run. Flat bar, spandrel, equal angle, C channel, and heat sink cover the bulk of what a working factory draws from stores, and each earns its place by doing a job a fabricated substitute does slower and less accurately.
