21 m Lighting Tower

Description

Negin Noor 21 m Lighting Tower

The Negin Noor 21 m lighting tower is a polygonal steel structure for very large areas where effective height, glare control and safe maintenance access matter. Its body is made from steel sheet formed into a tapered polygon and fully hot-dip galvanized after assembly for lasting durability in humid, industrial and windy environments.

Features of the 21 m Lighting Tower

• Wider coverage with fewer poles at large sites such as stadiums, industrial grounds and open-air multilevel car parks.

• Full hot-dip galvanizing of the structure and connections for excellent corrosion resistance.

• Project-specific head selection: 360° circular for all-round coverage, or stadium-style for directional distribution and glare control.

• Safe, fast lifting: electric with a motor and gearbox, or manual for lighter heads.

• Customization based on regional wind speed, design illuminance, head weight and floodlight brand/wattage.

• Options for a base electrical panel, electrical protection, safety equipment and controls.

Lifting System: Electric or Manual?

• Electric version, recommended for 21 m: for higher floodlight quantities/wattages or frequent servicing. The head lowers quickly for fast cleaning and replacement.

• Manual winch version: for economical projects with a moderately weighted head.

• Safety in both versions: galvanized steel wire rope, durable pulleys, suspension guide, limit switches/safety locks and servicing instructions.

Head and Lighting Arrangement (LED / MH / HPS)

• Select the arrangement according to target lux, distribution pattern, mounting height and head weight limits.

• 360° circular head: for squares, multidirectional areas and large car parks.

• Stadium head: for directional lighting at loading platforms, industrial buildings and sports grounds.

• Typical Range at 21 m, Finalized After Calculation:
  • LED (SMD/COB | IP65): approximately 16 to 32 floodlights in common wattages of 150/200/300/400 W.
  • Metal-halide/sodium, 400 to 1000 W: varied arrangements are possible depending on head type and weight limits.

• Note: Floodlight quantity and wattage are determined solely by lighting calculations and the load capacity of the head and lifting system, balancing light, weight and safety.

Suggested Technical Specifications

• Overall height: 21 m, with multiple sections and overlap or flanged joints according to the design.

• Sections: tapered polygonal, with the number of faces suited to diameter and thickness.

• Material: structural steel with staged quality control.

• Final coating: full hot-dip galvanizing of the structure and steel accessories.

• Wire rope: galvanized steel with a grade and size suited to the design load.

• Inspection hatch: safe access to terminals and internal equipment.

• Base electrical panel: switches and protection including MCB/fuse, RCD, phase protection and a lockable switch, with a durable electrostatic finish.

• Optional equipment: lightning protection, aviation warning light, rain cap, suspension guide, photocell/timer/manual switch and monitoring sensors.

Foundation and Installation

• Cast-in-place or precast foundation with standard formwork and an accurate anchor bolt template.

• Anchor bolts are supplied according to design results for quantity, diameter and arrangement.

• Provision of a layout plan, anchor bolt template and installation details suited to project conditions.

Factors Affecting the Price of a 21 m Lighting Tower

• Structural design, including diameters, thicknesses and number of sections, suited to regional wind conditions and head load.

• Lifting type: electric for faster servicing, or manual to reduce initial cost.

• Head type and required lux level: 360° circular or stadium-style.

• Floodlight technology and quantity (SMD/COB LED or MH/HPS), wattage and beam angle.

• Accessories and controls: electrical panel, photocell/timer, lightning protection, warning light and other equipment.

• Foundation and installation: cast in place or precast, soil conditions and installation constraints.

Applications

Sports grounds and stadiums, industrial and logistics sites, large car parks, terminals, urban squares and large multipurpose areas.
