Extrusions typically arrive in the form of handrails and window frames. Extrusions will always have an angle shape due to the extrusion process and can be either 6063 or 6061 extrusions. Depending on the source, there might be thermal break extrusion that has rubber/plastic down the center. This material must be sorted before shipping as it will most certainly result in a claim or downgrade.
There will likely be unpainted 6063 or 6061 material that can easily be upgraded within a truckload of painted extrusion.
