When considering bulk aluminum supply, several factors influence purchasing decisions beyond just price per kilogram. The actual cost per finished part over a production year matters most, and aluminum often outperforms steel in this regard. It machines faster, resists corrosion naturally, conducts heat and electricity efficiently, and its scraps retain value. These advantages attract industrial buyers looking for reliable, cost-effective metal products.

Indonesia extruded aluminum manufactures have been meeting this demand, with Exalum Metal standing out for its consistency and quality. As one of the trusted providers of Exalummetal industrial aluminum products, they offer a range of profiles pressed from certified billets to ensure tight tolerances over time. Here are five of their best sellers that dominate bulk orders.

1. Flat Bar

Flat bar aluminum is a staple in almost every fabrication shop, widely used for brackets, base plates, stiffeners, and busbar stock. The Exalum Metal catalog assigns each flat bar profile a specific code, removing ambiguity in repeat orders. For lighter applications, Section 10025 measures 19.00 x 0.90 mm, weighing 0.046 kg per meter. The versatile Section 10040 at 50.00 x 5.00 mm and 0.678 kg per meter suits general purposes, while the robust Section 10301, at 160.00 x 6.00 mm and 2.602 kg per meter, saves welding seams on broader brackets.

2. Spandrel

Spandrel aluminum profiles fill the solid band between glazing in curtain walls, hiding floor slabs and services while maintaining a sleek facade line. Project size largely dictates volume, often leading to single bulk shipments for large buildings. Type 62021 spans 100.00 mm, with a 5.00 mm return and 0.80 mm wall, weighing 0.248 kg per meter. For increased stiffness, Type 62040 features a ribbed surface at 135.30 mm wide and 0.345 kg per meter. These fluted profiles help conceal deflection and add structural integrity.

3. Equal Angle

Equal angle aluminum provides two identical legs joined at a 90-degree angle, making it ideal for corner reinforcement, frame bracing, panel edging, and rack construction. The catalog offers sixteen types, offering flexibility for various industrial applications. Type 20025 is a slim profile at 12.70 x 0.80 mm and 0.053 kg per meter, popular in furniture and enclosure manufacturing. Type 20080 is larger at 31.75 x 0.90 mm and 0.153 kg per meter, with a 127 mm perimeter that anodizes evenly, enhancing both appearance and corrosion resistance.

4. C Channel

C Channel aluminum or unequal channel profiles are U-shaped, with differing web and flange sizes. This design creates a natural retention groove for glass, panels, or boards, and can also house cabling. Exalum Metal produces five variants. The 32032 variant measures 25.40 x 12.70 mm with a 0.90 mm wall and weighs 0.119 kg per meter, frequently used for panel capping. The wider 32053 at 101.60 x 19.05 mm and 0.336 kg per meter suits applications requiring a single continuous edge on wide sheets, reducing the need for joint seams.

5. Heat Sink

Heat sink profiles carry fins and are designed to dissipate heat from power electronics, inverters, and lighting drivers. Thermal engineers pay close attention to the profile’s developed perimeter, a critical factor for heat dissipation. Code 96002 represents a large format option at 97.00 x 26.00 mm, with 1.20 mm thick fins, weighing 1.021 kg per meter and offering a perimeter of 689.313 mm, suitable for high heat load modules. Code 96005 is more compact at 34.50 x 20.00 mm, 0.399 kg per meter, and a 263.142 mm perimeter, often preferred for enclosed drives where space is limited.

Choosing the right aluminum extrusion profiles involves balancing mechanical properties, dimensions, and finish specifications. Together, these five aluminum extrusion profiles cover a broad spectrum of industrial needs. Flat bars serve general fabrication, spandrels conceal and strengthen facades, equal angles reinforce and edge structures, C Channels retain and organize panels or cables, and heat sinks manage thermal loads. Each profile is pressed from the same certified billet stock, ensuring consistent quality and dimensions even after repeated production runs at the Tangerang facility in Indonesia.
