Mast is a continuously taper polygonal cross section having one or more segment. It’s generally used for Area Lighting Purpose, Mounting National Flag, Signage Board, Stadium Lightning Purpose or other application like chimney etc. It has movable carriage for raising and lowering which is operated with a power tool motor through Winch gear box. It has capping unit comprising with Die cast aluminum Pulley. It is used for large area lighting with the minimum number of obstructions. UTKARSH High mast has design to withstand wind speed as per IS 875 (P-3):2015 and can be customized up to 300Kmph. All the mast has Hot Dip Galvanized by single dip seven tank processes. Mast has been designed considering minimum design life of 25 years.
