Steel-Craft Aluminum SA6000 overhead doors mix smart design with lightweight construction. The SA6000 design has no vertical stiles, so sightlines are clean and the look is contemporary. Our Thermoclear® lites deliver maximum visibility and high light transmission, helping to brighten large shops and work bays.

Custom extruded rails and stiles make for very strong doors, and our engineering and leading-edge manufacturing processes add further strength. Intermediate and bottom vinyl weather stripping and rails help the door to function well in harsh climates.

The SA6000 comes in a wide variety of colours, and a full selection of custom paint colours is available. Thermoclear® lites come in five colours to ensure you get the look you desire. 


The Steel-Craft Aluminum SA6000 door features leading edge design elements combined with extremely lightweight construction. Full view sections featuring Thermoclear® with no visible vertical stiles delivers a clean look, with maximum visibility and high light transmission.

Note: The glazing material (Thermoclear®) used is ideal for humid environments, however it differs from glass in that it's not sealed, therefore condensation may form in the cellular walls when interior/exterior temperatures are such that dew point temperatures are created (usually in periods of cooler weather). This condensation usually disappears when warmer weather returns.
