GFRC Spray Up Process

Glass Fiber Reinforced Concrete is made of a 1" thick cementitious skin, reinforced with alkali resistant glass fibers, and attached to a metal stud frame system. GFRC can be formed into ornate shapes, and its light weight provides many benefits for high rise buildings.

GFRC Architectural Precast Concrete Panel System

Panel Description

GFRC panels consist of a 1" thick solid concrete skin attached to a 16 gage 2" x 4" steel stud frame system. The overall thickness of this system is typically 6 ½". Studs are typically placed at 2'-0" on center and typically have 5/16" diameter galvanized steel pins welded to the steel frame and bounded to the concrete skin. The entire concrete skin and frame system weighs approximately 20 pounds per square foot. The maximum size of a GFRC panel is governed by the material properties, project requirements and shipping limits.

Architectural Design Capabilities

There are very few limits to the shapes and sections that can be achieved with a GFRC panel system. Some of the most ornate and decorative buildings in recent years have been made using GFRC panels. GFRC allows the designer to use deep panel sections without the weight of conventional precast. The lighter weight panels can minimize the cost of the building foundations, structural steel and panel supports. The metal studs of the GFRC panels may also be used to attach interior finishes. These aspects of light weight GFRC can amount to a substantial savings to the overall project cost. The mix design of GFRC typically consists of: white cement; sand; and a color additive to achieve the Designers desired look. Other materials such as black fleck can be added to create a different textured look. Multiple colors in the same panel can be done with GFRC.
