How High Mast Light Poles Are Designed to Meet IS 875, IS 1893 & EN 40 Standards

Modern infrastructure such as highways, ports, airports, stadiums, industrial zones, and urban intersections demands advanced lighting solutions. These lighting systems must deliver high illumination levels while ensuring structural safety. In addition, they must comply with stringent national and international standards to guarantee long-term performance and reliability. A high mast light pole must perform reliably under heavy wind loads, seismic forces, and long-term environmental exposure.

Improperly designed high mast lighting systems can lead to structural instability, uneven illumination, frequent maintenance, and safety risks – especially in high-wind or seismic zones common across India and global markets.

This article explains how high mast light poles are scientifically engineered to comply with IS 875, IS 1893, and EN 40 standards, and how Utkarsh India, a leading high mast pole manufacturer in India, delivers safe, durable, and high-performance solutions through advanced design, testing, and manufacturing excellence.

Understanding the Standards Governing High Mast Light Poles

IS 875 – Wind Load Resistance

IS 875 (Part 3) governs wind loads on structures. For a high mast light pole, wind pressure is the most critical design parameter due to its height and slender geometry.

Key design considerations include:

Basic wind speed based on location
Terrain category and topography
Gust response factor
Shape and drag coefficients

Utkarsh India designs high mast lighting systems customisable up to 300 kmph wind speed, ensuring safety even in cyclone-prone or coastal regions.

IS 1893 – Seismic Load Compliance

IS 1893 addresses earthquake-resistant design. Tall lighting structures must absorb and dissipate seismic energy without failure.

Design alignment includes:

Zone-based seismic coefficients
Dynamic analysis of slender structures
Load combinations with wind and dead loads

Utkarsh India’s in-house engineering team uses PLS and specialised structural software to ensure every high mast light pole complies with IS 1893 requirements, making them suitable for seismic zones across India and abroad.

EN 40 – European Standard for Lighting Columns

EN 40 defines performance, durability, and safety benchmarks for lighting poles used internationally.

Compliance ensures:

Structural reliability under fatigue loading
Corrosion resistance
Dimensional accuracy and material integrity

Utkarsh India manufactures CE-certified high mast poles, aligning with EN 40 and enabling global exports to Nepal, Rwanda, Oman, Qatar, Sharjah-UAE, Togo, and more.

Structural Design Excellence in High Mast Lighting Design

Optimised Geometry and Material Strength

Every high mast light pole is:

Continuously tapered
Designed with a 20-sided polygonal cross-section
Fabricated from high tensile steel plates with a minimum yield strength of 355 N/sq mm

This geometry improves aerodynamic performance, reduces vortex shedding, and enhances load-bearing capacity.

Advanced Welding and Base Plate Design

One or two longitudinal welds (no circumferential weld joints)
Internally and externally welded base plates for uniform load transfer
Foundation bolts made from EN.8 grade / E250 steel, sized for site-specific loads

These design practices ensure structural continuity and long-term fatigue resistance.

Superior Corrosion Protection & Galvanisation

7-Tank Hot-Dip Galvanizing Process

Utkarsh India uses a 7-tank galvanizing process, ensuring:

Uniform zinc coating
Superior adhesion
Extended corrosion resistance

Coating thickness:

85 microns for plates > 5 mm
70 microns for plates ≤ 5 mm

Both internal and external hot-dip galvanization are applied, with optional external PU paint for highly corrosive environments.

Engineered for Longevity and Safety

High mast light poles are long-term infrastructure assets that must perform reliably under continuous exposure to environmental stress, electrical loads, and operational demands. Therefore, engineered to minimise risk, extend service life, and ensure uninterrupted lighting performance.

Design life: Standard 25 years (extended life available on demand)
Aviation safety: Two red low-intensity LED aviation lights on the luminaire carriage
Access door: Vandal-resistant, weatherproof, positioned 500 mm from mast flange
Earthing terminals: 12 mm hot-dip galvanised bolts on base plate stiffener
Lightning finial: 1.2 m hot-dip galvanised finial, with optional copper-armoured down conductor

These features ensure compliance, safety, and uninterrupted operation.

Testing and Quality Assurance: Ensuring Proven Performance

To guarantee safety, durability, and compliance, every high mast light pole undergoes rigorous testing and quality assurance processes at multiple stages of design and manufacturing.

Certified Structural Design

All structural designs are developed using certified and industry-approved software, ensuring accurate load calculations, stress analysis, and compliance with IS 875, IS 1893, and EN 40 standards. This approach eliminates design uncertainties and ensures predictable performance in real-world conditions.

Wind Tunnel Testing Approved by IIT-Kharagpur

High mast lighting systems are validated through wind tunnel testing approved by IIT-Kharagpur, one of India’s most respected technical institutions. These tests simulate real wind conditions, verify aerodynamic stability, and confirm structural behaviour under extreme wind loads.

Comprehensive Load Testing and Product Inspection

Each high mast pole is subjected to comprehensive load testing and detailed product inspection to verify structural strength, dimensional accuracy, and assembly integrity. This ensures that every unit delivered performs exactly as designed.

World-Class Testing Facilities

Utkarsh India operates state-of-the-art testing facilities, including advanced spectrometers for chemical analysis. These facilities ensure strict control over raw materials, welding quality, and galvanisation processes, maintaining consistent product quality and adherence to international standards.

Together, these customisation capabilities and robust quality assurance practices ensure that every high mast lighting system delivers long-term reliability, safety, and superior performance in demanding infrastructure environments.
