Extruded Aluminum Sunscreens are constructed using a variety of extruded aluminum shapes assembled with welded construction and post painted to the specified finish. The assembly can consist of stock shapes such as aluminum bars, tubes angles or channels or can be totally custom with shapes such as foils, fins or blades. Whatever the required shape, the extrusions are engineered to withstand design loads and provide maximum span capabilities. These systems are custom designed to meet each projects design requirement.

If the extrusion you are looking for does not exist, Protean will have custom dies cut to meet your design intent. There are limitations to die sizes so contact Protean for availability. Aluminum is preferred due to its weight and strength properties and is paintable after assembly, however, primed steel supports concealed within the aluminum extrusions are common when spans exceed material and assembly limitations.

Attachment
Extruded aluminum sunscreens are most commonly attached to the building structure using custom designed aluminum retainers or outriggers. These elements can also be stiffened with primed steel if span requirements exceed material limitations. These assemblies can be attached directly to the building structure, curtainwall, sub-framing, or other building cladding material. Each design is engineered to insure structural stability and compliance with design load requirements.

Finishes

• Extruded aluminum assembly available in spray applied 70% Kynar 500 finishes
• Anodized finishes are also available, however, welds will be visible and may be discolored compared to extruded aluminum due to variances in alloys
