Decorative Foil Blade & Z Blade Shutter Louver Description

The Foil blades are also extrusions made from 6063-T6 aluminum with a uniform wall thickness of .045. The blades have a hollow airfoil shape with a height of 2 1/8″ and a thickness of .437 at the center with a reinforcing fin in the center. The middle blade has a weld on the side frame on the backside of the shutter. Therefore, eliminating the possibility of the frame bowing outward in high wind conditions.

The “Z” blade louver extrusions, made from 6063-T6 aluminum, have a uniform wall thickness of .062. The blades are a single wall with angled ends to form a shallow Z shape. Each louver is captured within the side frame to eliminate the possibility of the frame bowing in high wind conditions.

Visible Welds

With decorative shutters, the corner welds on both the front and back are ground down and sanded to produce a smooth continuous corner joint, eliminating any visible signs of the welds.

Beautiful Exterior Finish of our Decorative Foil Blade & Z Blade Shutters

All exterior aluminum surfaces are cleaned and etched, then powder coated with a polyester super durable powder. We highly recommend pretreatment with an epoxy primer on all shutters in high salt environments. This multi-step process meets the performance standards required by AAMA specifications #2604. Eighteen high gloss standard colors are available. As an additional option, 25 low gloss (30% – 40% gloss) colors and the nonstandard RAL colors (mostly at 80% – 90% gloss) are also available. All shutters are powder coated after assembly.
