STADIUM MAST

The Stadium High Mast are usually mounted with floodlights, and seen in places like stadiums, race course, etc. where high concentration of light is required over a small area.
The height of the pole and the number of units of floodlight are dependent either on the necessity for the requirement of the area, or as per the specifications mentioned by the client concerned.

Design and Finishing

The high mast shaft, the base plate and the anchor bolts that are used to manufacture the stadium masts are went through analysis via software so as to design the same. The designing is done as per AASHTO standard, ‘Standard Specifications for Structural Supports for Stadium Lighting and Luminaires’. The usual design comes with a wind speed of 160KM/hour and Gust speed of 208 KM/hour. However, changes and customizations can be made as per client’s requirement.
The shaft and the base plate are conducted through hot dip galvanization as per the recent revisions of BSEN 1461, with a coating of not more than 120 microns, generally. The galvanization of the anchor bolts, nuts and washers are done as per ASTMA153. Once the galvanization process is completed, no more cutting, wielding or drilling is done to the finished product.

Materials and Shape

With dimensions and thickness complying with the structural and functional need.. The Stadium High Masts are constructed and designed with continuously tapered steel with polygonal shape of sixteen sides. Sheets of steel are folded accordingly to the required shape. And then with the help of an Automatic Arch Welding Machine, the sheets are welded longitudinally.
Depending on the height of the mast, shafts are constructed out of multiple segments. The length of each segment is not more than 14 meter with a minimum overlap of 1.5 times across the flat of the female segment. The shafts are then equipped with a fixed headframe at the top to hold the flood lights. The headframes are then inclined at an angle up to 15 degree for aiming the lights.

Key Features of our Stadium Mast
  • The Stadium High Masts are equipped at the top of the shaft with fixed platform and service ladders for maintenance purposes.To reach the platform, a power lift or a caged ladder with resting platform is used.
  • The bottom of the shaft is welded with ‘circular base plate with holes’, suitable for anchor bolts. The welding process is conducted by double fillet weld, so as to match up to the international standards.
  • Base plates open at the center to allow cables to connect.
  • Nuts and washers, with size and dimensions as per structural analysis, complements the anchor bolts to fix the base plate to the concrete foundation.
  • The shaft consists of a door opening, at a convenient height. The dimension of the door opening complies with the requirements of electrical equipments.
  • A rubber gasket is provided at the doorframe so as to make it resistant to adverse weather conditions.
  • Steel hinges are used to fix the door cover to the shaft.
  • An Earthing lug is provided inside the shaft at the door opening, with necessary bolts, nuts and washers.
