About the Product
Stromberg HPGFRC (high performance glass fiber reinforced concrete) is a thin, light, strong material for wall panels and shapes for interior or exterior applications, wall cladding, soffits, spandrels and entire facades. It is available in smooth, textured or sculpted panels in both standard panel sizes and, on request, custom designs and sizes.
Features and Benefits
- Up to 20 times the impact strength of ordinary concrete.
- At 1/2" thickness, HPGFRC is 10 times lighter than ordinary 6" concrete panels.
- More freedom for designers, more options, less weight, and nearly unlimited customization options.
- Lower installation costs and less load on the structure.
- Space saving - thinner walls means more usable and leasable space.
- Reduced environmental impact.
- Panel sizes customized to your project.
- Completely non-combustible
- Durable enough to withstand hurricane-force wind loads, seismic loads, and fire.
- World's largest selection of pattern, color, and texture options...
- ...and of course the ability to create your own patterns or textures.

Uses and Applications
You can use HPGFRC both outdoors and in. Use it for building exteriors, wall-cladding, soffits, spandrels, accent panels, balcony surrounds, ceilings, and roofs. It can be used underwater and in severe freeze/thaw exposures.
Attachment
Installation
There are three basic attachment systems for HPGFRC:
- Z-clip system
- Aluminum z-shaped extrusions are attached to the substrate and these interlock with the mated clip on the back of the panel.
- Plate and Screw system
- Utilizes a concealed screw attachment at the joints between panels.
- Adhesive attachment system
- Utilizes structural silicone.
Typical Z-clip attached to an HPGFRC panel
In addition to the standard attachments, depending on your application, the panels can also be installed by cement mortar, by threaded inserts, or with traditional masonry techniques.
Joints
Joints between panels can either be a sealant joint or a rain screen system. Sealant joints use a backer rod and silicone. The rain screen system utilizes open, 'dry' joints.
Quality
HPGFRC panels are regularly tested, both internally and by independent testing labs with a battery of tests including strength, freeze/thaw resistance, anchor strength, consistency, and quality.
Neither fire nor ice have any effect on HPGFRC
Engineering
When needed, Stromberg's can provide stamped, signed engineer's drawings and calculations for the state where your project is located.
The Company
Reputation
The world leader in GFRC, Stromberg has produced GFRC for over 35 years. Stromberg GFRC has proven its quality thousands of times on successful projects around the world. Most of Stromberg's business (over 82%!) comes from satisfied return customers.
Stromberg panels utilize carefully tested and selected materials, trained production crews, and controlled production facilities. They are proudly made in the USA and have been approved and used on projects with the US Government, the US Navy, New York Transit, MTA, and many more projects across the USA and overseas.
Capacity
With a capacity of 50,000 square feet per week, no project is too large. Over 100,000 square feet of indoor production space and 15 acres of storage.
Shipping
Most projects ship by truck directly from our production facility to your jobsite. Typical transit time from our facilities in Texas is 48 hours for most projects in the USA. For Canada and Mexico, transit time is usually 4 days.
For most projects, panels are wrapped, palletized, and shipped by flat bed trailer to allow easy access for forklift unloading at the jobsite. Enclosed trailers are available on request.
