We are committed to providing extremely reliable pultruded crossarms. “When the storm hits, is your grid; STORM STRONG®?" Our Fiberglass Reinforced Polymer (FRP) STORM STRONG® crossarms are RUS approved and have been engineered to meet the requirements of the National Electric Safety Code (NESC) and to increase grid reliability.
The FRP crossarms are lighter and stronger than wood crossarms. They will not rot or succumb to woodpeckers or termites. The fiberglass crossarms exhibit an extremely high dielectric strength and contain no hazardous chemicals or pesticides. Most utilities find that the fiberglass crossarms provide the lowest installed cost. Many times, two wood arms can be replaced with a single fiberglass deadend crossarm and fiberglass tangent crossarm.
Fiberglass deadend crossarms are available in 3-5/8” x 4-5/8” and 4” x 6” rectangular sections. Fiberglass tangent crossarms are available in 3-1/2” x 4-1/2”, 3-5/8” x 4-5/8”, and 4” x 6” rectangular cross-sections. The 3-5/8” x 4-5/8” FRP crossarms were developed to be the most cost-effective and structurally efficient FRP crossarm available on the market! Our published values have been developed and fully evaluated per the requirements of ASTM D8019-15.
Our deadend crossarms are available with or without hardware. It is common for utilities to specify the crossarms predrilled with deadend phase hardware including washers, double-arm (DA) bolts, eye nuts, and a prefabricated center mount. With design values published per the NESC code, our deadend crossarms are fabricated with CNC equipment under strict quality standards and contain a minimum of three layers of UV protection for superior, long-lasting performance. All material hardware and steel fabrications are hot dip galvanized per ASTM D153.
FRP crossarms and poles can now be modeled within O-Calc Pro. O-Calc Pro is a structural analysis software tool. Interested in designing your next FRP utility pole or crossarm with O-Calc Pro, learn more at http://www.osmose.com/o-calcpro.
