Mild steel poles are durable, affordable, and versatile structures used for street lighting, utilities, and infrastructure projects. Made from low-carbon steel, they offer excellent strength, easy fabrication, and cost-effectiveness. With galvanization, they resist corrosion and deliver a lifespan of 25–50 years in Indian conditions.
Why Mild Steel Poles Matter
In modern India, infrastructure is the backbone of development. Whether it’s urban roads, highways, airports, or industrial complexes, poles play a vital role in supporting street lighting, utilities, and signals. Among all materials, mild steel poles stand out as the most cost-effective, durable, and versatile choice. From highways to residential areas, they ensure reliable performance while keeping costs under control.
What Are Mild Steel Poles?
Mild steel poles are fabricated from low-carbon steel containing 0.05–0.30% carbon. This composition makes them ductile, easily formable, weldable, and cost-effective. They are widely used across India for lighting and utility purposes due to their high strength-to-cost ratio.

Cost & ROI Analysis for Mild Steel Poles
Mild steel poles provide one of the best returns on investment in infrastructure projects. While aluminum poles may cost 30–40% higher, mild steel offers similar durability at a fraction of the cost. Over a 25–50 year service life, they deliver unmatched value.
Sustainability & Recycling Benefits
Steel is 100% recyclable without losing quality. Using recycled steel reduces CO₂ emissions significantly. For India’s large-scale projects, mild steel poles support sustainable development goals (SDGs).
Case Study: Indian Infrastructure Project Example
A recent NHAI highway lighting project adopted mild steel poles for a 60 km stretch. Compared to concrete, steel reduced installation time by 40% and ensured higher durability. With galvanization, the expected service life is 40+ years with minimal maintenance.
