The standard Indian wall-top concertina fence is a 600 mm coil cradled in Y-angle posts, with lines of razor tape on the arms. This is how it goes together, step by step.
M.S. angle posts bent or welded into a Y are set into the top of the wall every 2.4 m or 3.0 m. Each arm carries horizontal lines of razor tape or barbed wire — nine in the common tender item — and a 600 mm concertina coil sits in the V between the arms, drawn out to 50 turns per 6 m and clipped to the horizontals. It is measured and paid per running metre.
| Item | Quantity (typical) | Note |
|---|---|---|
| Y-angle posts | 34–43 | at 3.0 m or 2.4 m centres, plus one per end and corner |
| 600 mm concertina coil | 17 coils | at 6 m of run per coil (50 turns per 6 m) |
| Horizontal razor tape / barbed wire | about 900 m | nine lines, plus allowance for tying off |
| G.I. clips and staples | as required | to hold the coil pitch and the horizontals |
| Concrete for post holes | as required | paid separately in most tenders |
Steel in the coil and horizontals alone is about 2.0 kg per metre of fence (weight calculator).
