Fiberglass Purlins & Girts

Designed for High Load & Long Span Capability

Tuff Span™ Flanged Tube Beams are developed specifically for applications that require high load and long span capability plus corrosion resistance. This includes building structures, baffle wall columns, and support of tank cover decking. These sections utilize a custom design that optimizes structural properties and cost through innovative use of shape, glass fiber reinforcing, and manufacturing process. A common use is the secondary framing on pre-engineered metal buildings (PEMB), FRP, or fabricated structural steel buildings in new build or retrofit construction.

Tuff Span purlins & girts are designed for the harshest environments. Utilizing an iso-polyester or vinyl resin system provides outstanding corrosion protection and is fire retardant with a flame spread rating of 25 or less. The resulting combination of corrosion resistance, nonconductivity, and long span capability delivers significant end user benefits and life cost savings.

The flanged tube shape increases structural properties and contributes to easy installation.

Structural Performance

As a result of efficient design, 8F6 Flanged Tube Beams, at lesser weight and without bracing, carry more load than heavier FRP I-Beams and WF-Beams! 8F6 Flanged Tube, at 15% and 30% less weight, has greater load capacity than heavier FRP I-beams and WF Beams with bracing for single span conditions. For two span conditions, the 8F6 capacity is even greater.

Easier Installation

The flanged tube shape provides lateral stability eliminating the need for lateral bracing, plates or angles on primary framing, or sag rods. FRP components are lighter in weight and far easier to drill and cut in the field than steel components while not requiring hot work permits. These features provide time and cost savings to facilities.
