PUPI® tangents and crossarms are engineered for consistent strength and reliability. PUPI crossarms are engineered and manufactured using a fiberglass pultrusion process that minimizes material and process variation including three levels of weathering protection.
Proven fiberglass field performance in every climate.
Hundreds of thousands of PUPI fiberglass crossarms are at work in a wide range of environments throughout North America and around the world. From hot, wet and dry climates to extreme cold – not a single PUPI crossarm has failed due to environmental degradation.
PUPI Crossarms are GREEN Products.
PUPI fiberglass utility products are an environmentally-friendly alternative to wood. They are long-lasting, use recycled materials and require no harmful chemicals as preservatives. Click here to read our green fact sheet >

The advantages of fiberglass vs. treated wood:
Wood beams, although carefully specified to control defects, still show considerable natural variances and gradually deteriorate over time. Wood and fiberglass by comparison:
Treated Wood:
PUPI Fiberglass:
Heavy with strength variances
Lightweight with consistant strength
Deteriorates with exposure
Three levels of UV protection
Conducts electrical current
Excellent dielectric properties
Rigid with little deflection
More than twice the deflection
CCA and harmful chemicals
Environmentally safe materials
Potential for splintering
Non-splintering
Susceptible to insects
Impervious to insects
Susceptible to woodpeckers
Impervious to woodpeckers
Good deflection vs. fracture. Unlike the natural variances found in wood beams, PUPI fiberglass crossarms are known for their uniform and predictable strength – in any climate. Tests comparing an 8 ft PUPI crossarm and a similar size wood beam show that around 2,800 pounds wood deflects a little over an inch and fails. The PUPI crossarm under the same weight is structurally sound and hasn’t even reached half its load rate. PUPI fiberglass crossarms show predictable deflection that greatly enhances reliability and the ability to withstand transient and impulse loads in extreme conditions.
