Enhanced Fiberglass Crossarms
Ditch the wood. Build for the future. The demands on today’s grid are higher than ever—yet much of the infrastructure still relies on aging wood crossarms that rot, burn, weaken, and fail long before their time. Utilities are being asked to deliver unprecedented reliability with components that were never designed for a modern grid.
The enhanced UVMAXX™ fiberglass crossarm family changes that.
Engineered for extreme resiliency, rapid installation, and long-term performance, UVMAXX™ outclasses wood in every critical metric—strength, lifespan, safety, and total cost.
MacLean Power Systems is pleased to announce the expansion of the UVMAXX™ fiberglass crossarm system with the introduction of the PT, PF, and PK Series. These additions strengthen the long-life composite portfolio and provide utilities with more resilient, fire-resistant, and field-friendly options for modern grid construction.
The UVMAXX™ system includes advanced features such as radial beam construction for greater strength, a UV-protective outer layer bonded directly to the core, mechanically locked endcaps for long-term reliability, and a non-welded mounting hardware system designed for durability and consistent field performance. The result is a crossarm platform engineered for extended service life, reduced maintenance, and dependable performance under demanding conditions.
