Hollaender Manufacturing Company produces a wide array of architectural railing systems. These hand and guard railing systems can be designed to fit individual projects by engineers at Hollaender.
The Interna-Rail® KLEAR is a glass railing system, it offers transparency and visibility. The glass infill goes up to the 42" height requirement without a top cap on the glass: The glass is held at the post rather than the top and bottom, thus minimizing the number of horizontal rails in the system and maximizing visibility.
Interna-Rail® KLEAR posts are attached with a grab rail or handrail at 36" above the walking surface on level, ramp, and stair railings.
| ||Uniform load ||Concentrated load |
|Top Rails of Guards ||50 lb/ft. applied in any direction ||200 lb/lf. applied in any direction |
|Infill Area of Guards || ||Horizontal concentrated load of 50 lbf. applied to 1 sq. ft. at any point in system, including panels, intermediate rails, balusters, or other elements composing infill area. Load on infill area need not be assumed to act concurrently with loads on top rails. Glass infill shall have a safety factor of 4 |
|Handrails ||50 lb/ft. applied in any direction ||200 lb/lf. applied in any direction |
*Uniform and concentrated loads need not be assumed to act concurrently.
|Tempered Glass ||ASTM C1048, Fully Tempered, Condition A, Type 1 (Transparent Flat Glass), Quality Q3 |
|Glass infill panel ||3/8” or 7/16” laminated thickness with maximum spacing between posts to be 4 ft. |
|Resin panels ||acrylic 3/8” thickness from Lumicor or other architect approved vendor. |
While maintaining structural integrity, the glass railing provides more visibility than competitive railing systems since it does not use a top cap. No drill holes are required in the glass, resulting in a much lower cost per foot than other systems.
Materials and Finishes
|Posts ||Aluminum 6005-T5, 1 ½” IPS (48.2 mm O.D.) Schedule 80 Wall (clear anodized) |
|Rails ||Aluminum 6063-T6, 1 ½” IPS (48.2 mm O.D.) Schedule 40 Wall (clear anodized) |
|Fittings ||Aluminum 6063-T6 (clear anodized) |
|Base Flanges ||Cast aluminum |
|Fasteners ||Stainless steel 304 alloy |
The rails are made from clear anodized aluminum, resulting in a railing that is 25-50% less costly per linear foot than stainless steel. Finishes come in a range of patterns, colors, and textures. Aluminum systems can be anodized with clear and bronze options, or powder coated in almost any color.
