Composite PU utility pole estimated to have a minimum life span of 65 years

14-May-10
USA uses PU composite for utility poles. The composite PU utility poles in the USA erected in the post-World War II era, are over 60 years old, and still good condition as found out by Bayer Material Science. The poles are formed by filament winding process which places fiberglass on the axial surface of the pole with 0� winds. Typically, most winding processes compose angles of 7-8�. As with traditional filament winding, the process is automated and the fibers are precisely placed onto a mandrel. With the glass and polyurethane resin strategically placed, a pole wall thickness is no more than 12 mm and a maximum height of about 55 meters. The PU composite poles are tapered and hollow and can therefore be nested into compact bundles, saving space in transit and leaving more room for more poles to be transported to the job site. PU composite utility poles are expected to last as long as 125 years in most climates, and are engineered for a minimum of 65 years in the most challenging climates.

Resin System Inc from Calgary, Canada is one of the leading suppliers of composite PU utility pole. The company�s polyurethane composite utility poles have withstood a direct hit by a tornado in Texas and weathered harsh Scandinavian winters. The RStandard utility poles are the highest strength-to-weight ratio poles on the market, withstanding weather conditions where conventional utility poles have failed. Polyurethane raw materials from Bayer MaterialScience LLC are part of the formulation for RS� proprietary polyurethane composite, from which the poles are formed.

The poles are formed from RS� proprietary filament winding process which places fiberglass on the axial surface of the pole with 0� winds. Typically, most winding processes compose angles of 7-8�. As with traditional filament winding, the process is automated and the fibers are precisely placed onto a mandrel. With the glass and polyurethane resin strategically placed, a pole wall thickness is no more than 12 mm and a maximum height up to 165 feet. In addition to being a more eco-friendly alternative to wood, the polyurethane composite utility poles are expected to last as long as 125 years in most climates, and are engineered for a minimum of 65 years in the most challenging climates. The lightweight properties of our polyurethane composite combined with our filament winding process results in poles that are one-tenth the weight of concrete, one-quarter the weight of steel and one-half the weight of wood, which is another significant advantage.

With the polyurethane composite, costs associated with transportation, installation and storage are also reduced. The poles are tapered and hollow and can therefore be nested into compact bundles, saving space in transit and leaving more room for more poles to be transported to the job site. The RStandard poles can also be drilled in the field, meaning that crews can make modifications during installation, such as drilling in holes for climbing steps. The surface of the composite poles is resistant to staples and easily cleaned of graffiti. RStandard composite poles can be used as transmission and distribution poles to carry electric grids and as communication structures for various uses including wireless networks and microwave communications systems. Particularly comes in handy as the poles reach over 100 feet when fully erected. The RStandard poles are also field-drillable, meaning that crews can make modifications during installation, such as drilling in holes for climbing steps. Furthermore, the surface of the poles is resistant to staples and easily cleaned of graffiti
