Extruded shapes can be simple or highly complex, and are generally of three types based on cross section view: hollow, semi-hollow or solid.


Aluminum shapes are formed using the extrusion process. The extrusion die design determines the cross-sectional dimensions and shape of the extrusion often referred to as the profile. Shapes can be simple or highly complex. Shapes are categorized as hollow, semi-hollow or solid based on the cross section view

Hollow Profile ... 
A profile any part of whose cross section completely encloses a void.

Semi-Hollow Profile ...
A profile any part of whose cross section is a partially enclosed void area of which is substantially greater than the square of the width of the gap.

Solid Profile ...
A profile other than hollow or semi-hollow.

Shapes are commonly designated as standard or custom. Standard structural profiles include: Angle Equal Legs, Angle Unequal Legs, Structural Angle Equal Legs, Structural Angle Unequal Legs, Channels, I-Beams, H-Beams, Tees, Zees, Bus Bar, Hex Bar, Square Bar and Rectangular Bar. 

All shapes that are not standard are designated as custom. Profile specific dies must be designed for all custom shapes. Forward a CAD drawing for a quote on your custom design. For design collaboration, please contact our engineering department.


Aluminum can be extruded to tight dimensional tolerances providing near-net shape design capability. With the near-net shape design capability, highly complex and intergral shapes can be designed, often replacing multiple component parts necessary with other materials. The near net design feature also reduces scrap generation during the fabrication process. The scrap generated is totally recyclable contributing to the overall cost effectiveness of aluminum extrusions.

Aluminum extrusions surpass all other structural materials in design, performance, reliability, efficiency, cost and repeatability starting with the net shape design capabilities to joinability, workability, machineability and finishability.

Shapes can be designed and Extruded to Fit. Two or more parts working in tandem to meet specific application needs.

No material can match the heat dissipation characteristics of aluminum. This quality combined with the capability to extrude tight tolerance, complex shapes makes aluminum the material of choice for heat sinks.

The ability to mix and match aluminum characteristics to meet end item requirements makes aluminum the most versatile metal available. Custom aluminum shapes can be designed to meet thousands and thousands of applications. Aluminum extrusions can incorporate holes, slots, or screw bosses longitudinally into the shape profile while holding tight tolerances. The shape profile can be as simple or intricate as needed to meet your application. In addition, aluminum is highly fabricatable and accepts many finishes.
