What finishes are available?
A. A variety of finishes are available with steel, including galvanized, paint over galvanized (powder coat or liquid), dulled and darkened galvanizing and weathering steel. Below-grade coatings are available for direct embedded poles. Click here for additional coatings information. Q. Our standard practice for deadending 3 phase construction is to deadend the outer phases on the arm and the center phase on the pole. When we do this we take advantage of the insulating properties of the wood. What happens when we go to a steel pole, do we A. In short, if your desired BIL or critical flashover voltage calculations include the insulating properties of the wood pole, then the results will be different with a steel pole. The differences can either be overcome by using different hardware (i.e. larger insulators, bigger air gap, fiberglass material change) or by evaluating the BIL of the steel installation and how it supports your overall reliability goals. We are happy to work with you regar
