Overview

Why Specify Perforated Metal Infill?

Our perforated infill panels are available in a wide variety of patterns. They are constructed of carbon steel that is e-coated and powder coated, powder coated aluminum, or stainless steel. Steel panels are 14 gauge, held within an 11 gauge steel hem, with three holes drilled in the bottom hem to allow water to quickly drain. Available for level or raked (stair) applications.

The no-frame option eliminates the fabricated hem around the outside edge of the panel — our most cost-effective infill panel system. This option is only available in level sections, with a maximum open area of 50%.

Aluminum perforated panels are available in the same hole patterns as steel, but the material is thicker at .125" with 11 gauge hems. Stainless steel panels are available for projects requiring superior corrosion resistance, with a #4 satin polish standard.

YMCA at CityWay

Architectural firm Browning Day, tasked with the design for the new YMCA at CityWay in Indianapolis, was looking for a railing design that was diversified enough to handle both glass infill panels and metal infill panels. A common railing design with different infill panels for both stairs and mezzanines would offer a wider range of aesthetics than one uniform infill panel system.

Frankie's Fun Park
Huntersville, NC

Frankie's Fun Park

Frankie’s Fun Park opened their fifth location in Huntersville, North Carolina and called upon ADW Architects to design the facility. The combination of amusement rides, exhibits, dining and outdoor accessibility required various railing designs and products. As a full-line manufacturer with complete engineering and design services, Hollaender Manufacturing provided railing for all of Frankie’s design and utility needs. Frankie’s needed a “one-stop shop” for their complete railing system needs and Hollaender’s mechanically fastened aluminum railing systems covered all their requirements. The design required Hollaender's aluminum Speed-Rail® 2-line queue railing, Speed-Rail® with perforated infill panels, Interna-Rail® ADA accessible ramp railings and Interna-Rail® with acrylic panels. Hollaender railing systems are showcased at Frankie’s other South Carolina locations in North Charleston, Greenville, and Columbia and continue to serve the staff and patrons of Frankie’s well.
