When sourcing metals in large volumes, several factors become critical, such as weight, corrosion resistance, and machinability. Aluminum excels in all these areas, making it a preferred material for bulk buyers. Its light weight, about one-third that of steel, allows more meters of product per shipment, and its natural oxide coating eliminates the need for galvanizing or repainting. Moreover, aluminum is easy to cut and weld, conducts heat and electricity efficiently, and retains scrap value at the end of its lifecycle.
If you are exploring options for an Indonesia aluminum factory, Exalummetal is a long-established player known for consistent quality and reliable delivery. Among the Exalummetal industrial aluminum products that attract bulk orders, five stand out as the most popular choices. Each product meets different functional needs across construction, fabrication, and electronics cooling, all backed by the same high-grade aluminum billets and production standards at their Tangerang facility.
1. Flat Bar
Flat bars are the top choice for many bulk enquirers because of their versatility. They serve as brackets, stiffeners, base plates, and busbar stock with minimal preparation. Exalummetal’s catalog includes fixed profiles, each with a unique section number, allowing buyers to specify codes, lengths, and tonnage precisely. For example, section 10030 offers a solid flat bar measuring 25.00 x 5.00 mm at 0.339 kg/m, ideal for bolted bracket fabrication. Thicker options like section 10205, sized 35.00 x 16.00 mm at 1.508 kg/m, provide more strength where needed. The flat bar’s adaptable dimensions make it a reliable choice for many metalworking applications.
2. Spandrel
Spandrel profiles are specialized for façade work, placed between glazing runs to conceal slab edges and utilities while preserving the curtain wall’s uniform appearance. Bulk orders are usually made per tower due to the profile’s architectural function. Profile 62030 has a span of 106.50 mm with a 9.00 mm return and a 1 mm wall, weighing 0.350 kg/m. A ribbed variant, profile 62040, offers a fluted face for extra stiffness across the span, measuring 135.30 mm wide at 0.345 kg/m. These profiles are pressed from dedicated dies to ensure accuracy and performance in high-volume facade projects.
3. Equal Angle
Equal angle profiles form two equal-width legs joined at a right angle, providing corner reinforcement, frame bracing, panel edges, and rack fabrication solutions. Sixteen types are available, enabling bulk buyers to select profiles by weight and size. Lighter types, like 20046 at 19.00 x 1.20 mm and 0.120 kg/m, are suitable for cabinet makers requiring long production runs. Heavy-duty angles such as 21021 measure 30.00 x 5.00 mm at 0.745 kg/m, designed for structural bracing under load. Their uniform shapes allow straightforward connection and support in various assemblies.
4. C Channel
C Channels, or unequal channels, come with preformed retaining grooves that save fabrication time. Available in five variants, these U-shaped profiles vary in dimensions to match specific clamping or edge-finishing needs. For instance, variant 32042 is deep, at 12.70 x 50.80 mm with a 0.90 mm wall, perfect where tall flanges are needed to grip panel edges. The wide format 32053 is 101.60 x 19.05 mm at 0.336 kg/m and can cover entire sheet edges without joints. This variety enables precise fit and finish for metal enclosures and frames.
5. Heat Sink
Heat sink extrusions are key components in electronics cooling, with fin arrays that dissipate waste heat from devices like inverters and lighting modules. The perimeter length of fins per meter is a vital cooling metric. Product code 96001 measures 49.90 x 60.00 mm with 1.25 mm fins, weighing 0.799 kg/m, delivering 444.736 mm of perimeter. It’s well-suited for cabinet-mounted power stages. For tighter spaces, code 96005 offers a compact 34.50 x 20.00 mm profile with 0.399 kg/m and 263.142 mm perimeter fin surface, ideal for enclosed drives needing efficient heat dissipation.
Together, these five aluminum profiles cover a broad range of applications for bulk buyer. Flat bars for fabrication, spandrels for facades, equal angles for reinforcement, C channels for panel retention, and heat sinks for thermal management.
