Louver Architectural Grating

Architectural Grating

Vertical/Horizontal

The unique flexibility of the "LG" series allows architectural freedom for both vertical and horizontal applications. Vertical applications allow for maximum air flow and resist the accumulation of snow, rain, dirt and debris. Screening of parking structures and visual concealment of unsightly ventilation or mechanical equipment is easily accomplished. Installed horizontally, the multiple tilt patterns provide options for sunscreens and building facades. Once again the high percentage of open area allows for important air circulation and the free passage of moisture.

Finishes

The natural corrosion resistance and beauty of mill finish aluminum can be enhanced with clear anodizing. Other popular anodizing options include light and dark bronze shades. Powder coating, epoxy and Kynar finishes are available in the complete RAL color palette. Properly applied, these finishes offer years of continuing service in colors designed to complement the look and feel of adjacent architecture.

Fabrication

"LG" series products are easily fabricated to any size and configuration. Radial or diagonal cuts accommodate "free-form" design beyond simple squares and rectangles. Louvers can be welded into component framework and quickly bolted to the supporting structure with limited field labor. All fabrication can be completed prior to coating, maximizing the integrity of the finish.
