PUPI® is the leader in fiberglass crossarms for the electrical utilities industry. Available for H-frame structures, PUPI transmission crossarms and braces are engineered for maximum strength and consistent performance in a wide-range of standard and made-to-order configurations.
With exclusive SunGUARD® UV resistant coating and TorqueGUARD™ bushings, PUPI crossarms are proven to withstand the elements better than wood, steel or other composite beams – in any climate! Our PUPI H-Frame product line has been deliberately designed to be easy and intuitive to install.
Our Series 5000 transmission crossarm is a one-to-one dimensional replacement for wood, but with a dramatically lower weight, twice the strength, and equal stiffness. Generally, this allows utilities to use existing industry hardware and installation practices.
By leveraging the strength of a fiberglass crossarm, utilities have the opportunity to optimize their designs to streamline construction, ease installation, and reduce first cost.
