Street Light Pole Standards in India: which IS codes matter and what each one covers

Why standards matter when you buy a pole

A standard is a shared rulebook. When a tender says “as per IS”, every bidder is expected to price the same thing, and the buyer has a clear way to check what arrives. When a quote names no standard at all, the buyer has only the supplier’s word.

The trouble is that one pole project touches several different documents. One covers how bright and how far apart the lights should be. Another covers the steel tube. Another covers the coating. None of them replaces the others. Mixing them up is the most common reason a quote does not match a tender.

This guide does not copy the standards, which are published by the Bureau of Indian Standards (BIS). It tells you what each document is about, quotes only what we could read in the published text, and shows where to look for the rest. For the rest of your planning, our height and spacing guide and our foundation design guide go deeper on layout and the base.

The map: six questions, six documents

Table 1 lists the documents that come up most often in street light pole work. They sit at different points in the job, which is why Drawing 1 shows them in a line. A road lighting designer starts at the left. A pole manufacturer works in the middle. An inspector or a buyer checks the right.

These are national documents, and each has editions and parts. The editions we read are named in this guide. BIS may have issued newer editions, so always confirm the edition your tender or your engineer names. Our street light pole range and tubular pole range pages list what we make. The tubular pole page says that, where project specifications require it, manufacturing follows IS 2713 and IS 1161.

Road lighting: what IS 1944 says about height and spacing

The road lighting code is IS 1944 Parts I and II (1970), published by BIS as a first revision. Its scope says it gives guidance to public lighting authorities on planning, installing and maintaining public lighting, and it deals only with electric lighting. It states that its classification is one of lighting and not of roads, so a road is grouped by the lighting it needs.

The code then gives rules of thumb for the layout. Drawing 2 shows the four arrangements it names. The choice depends on the road width compared with the mounting height.

Check a layout against the code ratios

Enter your mounting height, the type of luminaire and the road width. The calculator applies the three rules above. It is an arithmetic check on the 1970 text, not a lighting design. Your lighting designer or your tender sets the real limits.

For the full method, including how to test your own layout, see our pole height and spacing guide.

Junctions, bridges and special sites

Not every site is an ordinary road. IS 1944 has separate parts for places where the lighting problem is different. IS 1944 Part V (1981) is titled “Lighting for Grade Separated Junctions, Bridges and Elevated Roads (Group D)”. It also helps designers choose between conventional column lighting and high-mast lighting at junctions.

IS 1944 Part VII (1981) is titled “Lighting for Roads with Special Requirements (Group F)”. Its scope covers roads in the vicinity of aerodromes, railways, docks and navigable waterways, and it calls for prior consultation with the authorities concerned.

If your site is a flyover, a bridge or a road near an airport, say so in your enquiry. These sites usually need a specific design, and the pole is only one part of it.

The pole and the tube: IS 2713 and IS 1161

The pole is built from a steel tube, and the tube has its own document. The BIS summary of IS 1161 gives the title “Steel Tubes for Structural Purposes – Specification”. Its scope covers hot finished welded, hot finished seamless, and electric resistance welded or high frequency induction welded plain carbon steel tubes for structural purposes. You can read the IS 1161 summary on the BIS site.

IS 2713 is the document for the pole itself. It names the pole designations that tenders use, such as the 410 SP series. Our 410 SP table guide shows how to read those names, and our MS vs GI comparison explains the material choice.

Our site states that, where project specifications require it, manufacturing follows IS 2713 and IS 1161. We read that as a statement about how we work, and we suggest you ask any supplier to confirm in writing which standard and which edition apply to your order.

Coating, wind and the ISI mark

Coating and wind are the two things that decide how long a pole lasts in the open. IS 4759 covers hot-dip zinc coatings on structural steel, so a buyer who wants a galvanised pole can ask which coating standard the supplier follows and how the coating is checked. Our site says each pole undergoes hot-dip galvanising and that powder coating is available as an option.

IS 875 Part 3 covers wind loads on structures. A tall pole with a heavy fitting catches more wind and puts more load on its base, which is why a structural engineer should check the pole and the foundation together. Our foundation design guide shows what the base drawing should contain.

The ISI mark is a separate matter. The ISI mark article on Wikipedia says it certifies that a product conforms to an Indian Standard, that BIS runs it, and that it is mandatory for some products and optional for most. If a supplier says a product carries the mark, ask for the licence details and check them with BIS.

Standards finder: what to name in your enquiry

Pick the situation that matches your project. The finder shows which document to name and gives you a few lines to paste into an enquiry or tender query. Nothing is stored. The text is built in your browser, and the lines come from the sources linked in this guide and from our own product pages.

How to write standards into an enquiry

Good standards language is short. It names what you need, the part, the edition and the proof you want. Use the list below before you send an enquiry, and ask every bidder the same questions.

• The road group and the mounting height your lighting designer has set.
• The layout: single side, staggered, opposite or axial, with the pole spacing.
• The pole design and the document that names it.
• The tube standard and the edition.
• The coating standard and how the coating is checked.
• The wind speed or wind zone used for the design, and who checked the base.
• The proof you want: test reports, licence details or an inspection plan.
• The delivery cost, time and GST on each line. Our price guide and HSN and GST guide explain those lines.
