Custom Aluminum Extrusion from an Indonesia Manufacturer: 5 Profiles to Start With

Custom Aluminum Extrusion from an Indonesia Manufacturer: 5 Profiles to Start With

Tooling for simple aluminum extrusion shapes costs less and can be made faster than steel tooling. That difference can make custom cross-sections more practical for a factory to order, especially on projects that need a profile designed for a particular purpose. 

PT Exalum Metal Indo was established in 2009 and is among Indonesia extruded aluminum manufactures with a dedicated team to design and produce dies to customer specifications. Customers can also request billets in their preferred alloy series, so customization covers both the cross-section and the material. These capabilities support Exalummetal industrial aluminum products, which can be ordered to suit a project’s dimensions, specifications, and finish.

1. Flat Bar

Flat bar serves as electrical busbars, machined components, structural supports, and architectural trims. Customers may request full extrusion lengths or precision cuts, with clear anodizing, black anodizing, and custom colors available. 

Several flat bar sections are commonly utilized across various industries. Section 10204 measures 120.00 mm wide and 8.00 mm thick, with a corner radius of 2.00 mm and a weight of 2.592 kg per meter. That radius makes it a rounded-edge option, one of 12 in the catalog alongside 28 with straight corners. A 100-meter order weighs 259.2 kg.

2. Spandrel

Spandrel profiles are used for exterior soffits, ceiling panels, wall cladding, and gas station canopies. Exalum offers anodizing, powder coating, and mill finish, while a wood-grain appearance is available through sublimation powder coating.

Section 62040 is 135.30 mm wide, with a profile height of 5.50 mm, a wall thickness of 0.80 mm, and a weight of 0.345 kg per meter. Its corrugated cross-section has trapezoidal ribs, unlike the stepped flat-panel forms of Sections 62021 and 62050.

3. Equal Angle

Equal angle profiles can be used for corner protection, structural frameworks, architectural edging, shelving, and brackets. Finish options include standard mill finish, clear anodizing, and custom powder-coated colors.

Section 20091 has 40.00 mm legs, a thickness of 4.00 mm, and a weight of 0.824 kg per meter. Section 20092 is also 4.00 mm thick, but its legs measure 50.00 mm and it weighs 1.040 kg per meter. 

4. C Channel

C Channel, also called unequal channel, can protect the edges of plywood, MDF, glass, and composite panels. In industrial applications, it can also serve as a guide rail for panels and sliding doors. A custom die can add features such as drainage slots, fixing holes, and radiused flange tips.

Section 32042 measures 12.70 mm wide, with legs 50.80 mm high, a wall thickness of 0.90 mm, and a weight of 0.182 kg per meter. In comparison, Section 32053 is 101.60 mm wide and has legs only 19.05 mm high.

5. Heat Sink

Heat sinks are used to cool inverters, transformers, amplifiers, and telecommunications equipment such as 5G base stations. Their fins can be straight, flared, or serrated, and closely spaced, tall fins increase the cooling surface area. Before a die is made, Exalummetal’s engineering team can work with buyers to optimize fin geometry and base thickness.

Section 96003 is 50.00 mm wide and 60.00 mm high, with a wall thickness of 1.50 mm and a weight of 0.875 kg per meter. Section 96001 has nearly the same outside dimensions, at 49.90 mm by 60.00 mm, but its wall thickness is 1.25 mm and its weight is 0.799 kg per meter.

The lower cost of aluminum tooling creates an opportunity to order custom cross-sections from an extrusion factory. Flat bar, spandrel, equal angle, C Channel, and heat sink can each provide a starting point before you design a die of your own.

Start Your Custom Aluminum Extrusion Inquiry

After reviewing the profiles, share your requirements with an extrusion factory in Indonesia. Exalummetal accepts requests for custom dimensions, specifications, and finishes through its die and engineering teams. You can contact the company via WhatsApp at +62 811 9429 970 or email [email protected]. Shipping is available worldwide, including to the United States, United Kingdom, Australia, and Canada.

When making an inquiry, include the section number, cut length, quantity, and desired finish, such as anodizing or powder coating. If you need a new die, provide the cross-section specifications as well.
