CONICAL CURVED POLES
The conical bent poles in sheet metal are constructed by bending of circular trapezoid steel sheet S235JR (UNI EN 10025), then the longitudinal edges facing after bending are welded using automated certificate IIS.
At each pole are made the following processes:
- cable entry slot;
- application of pocket grounding;
- terminal board slot.
All poles, thanks to the taper of 10 mm/m ending at the top with a diameter of 60 mm suitable to the mounting of a street lighting.
Subsequently, the straight poles are subjected to cold bending on suitable matrices and by the action of an electric winch assume the required curvature.
The galvanization of materials is obtained by dipping into bath of molten zinc which thickness of the zinc coating is conform with UNI EN ISO 1461.
The poles are made in compliance with the UNI EN 40-5 and related regulations:
Dimensions and tolerances: UNI EN 40-2;
Materials: UNI EN 40-5;
Specification for characteristic loads: UNI EN 40-3-1;
Verification by calculation: UNI EN 40-3-3;
Surface protection: UNI EN 40-4.
Each post comes with adhesive label CE.
