Aluminum Extrusion Applications

There are a couple instances when using aluminum would be better than using our rigid PVC extrusions. The two instances are for heavy weight-bearing applications and applications where there is high heat involved. Although rigid PVC is strong, it is not as strong as aluminum. It is also not as heat-resistant as aluminum. In these applications, please use aluminum instead.
