Chain link fence installation: how it is done, step by step

Last updated

Chain link fence installation starts with braced terminal and corner posts set in concrete, then line posts every 2.5 to 3 m. Once the concrete has cured, line wires are strained between the terminals, and the mesh is stretched and tied to them and to every post. SIMO Securon installs it anywhere in India, or supplies your contractor.

A chain link fence, also called cyclone fence or jali, is a woven mesh held up by posts and line wires. The mesh has no knots to keep it rigid, so it needs a post every 2.5 to 3 m, and its strength comes from the posts at each end of a run:

  • Terminal posts at the start and end of each run, and corner posts where the line changes direction, set in concrete and braced, because they carry the pull of the mesh.
  • Line posts between them, every 2.5 to 3 m.
  • Line wires strained between the terminals: IS 2721:2025 asks for two line wires up to 2 m high, and three from 2.5 m.
  • The mesh, stretched along the run and tied to the line wires and to every post.

Chain link fence, elevation. A starting design for discussion, not for construction. Every job is built to the drawing agreed for it.

The post size, the foundation and the bracing depend on the height, the mesh, the wire and the ground, so each job is built to its own drawing.

  1. Set out the line. Walk the boundary, mark the corners, gates and changes of level, and agree the line. Mark the terminal and corner posts first, then the line posts every 2.5 to 3 m between them.
  2. Set the terminal, corner and gate posts. Dig their holes, set them plumb in concrete, and fit the bracing: a diagonal brace on each terminal, and corners braced both ways. Treat each gate post as a terminal, so the gate’s weight never hangs on the mesh.
  3. Set the line posts. Run a string line between the terminals, and set each line post to it, at the same height and plumb.
  4. Let the concrete cure. Keep it damp and wait at least 7 days with ordinary Portland cement (OPC), or at least 10 days with PPC or another blended cement, or in hot, dry weather: the curing periods of IS 456. Straining wires early pulls the terminals out of line.
  5. Strain the line wires. Fix each line wire to one terminal, run it along the posts, and strain it at the other terminal, then fix it to every line post.
  6. Hang and stretch the mesh. Fix the end of the roll to a terminal post, unroll it along the line wires, stretch it evenly so the diamonds stay square to the posts, and fix it at the next terminal. Join rolls by weaving a wire through the last diamonds of both, so the mesh runs on without a gap.
  7. Tie the mesh. Tie it to each line wire and to every post along its height, and check that it stands straight and taut between the posts.
  8. Fit the gates and any topping, then walk the line: check each post, each brace and the mesh, and clear the site.

Work safely: wear gloves, eye protection and safety boots, and never stand in line with a wire under strain.

Supply only, or supplied and installed?

SIMO Securon makes chain link and offers it three ways:

Service What it is Suits
Supply only The chain link, with QvikFixrr™ posts and fittings, for your contractor to install; SIMO Securon can train that team on site Buyers with a trusted contractor, or projects that tender installation separately
Supply and install SIMO Securon supplies everything and its crews install it, anywhere in India, under one contract Most buyers: correct installation is what rated life assumes
Turnkey Site survey, engineering design to agreed drawings, supply, installation, inspection and handover with documentation Large industrial, solar and infrastructure projects

SIMO inspects every order; external testing and third-party inspection are available on request, at extra cost. Read more on SIMO Securon’s installation services.

Rated life assumes correct installation: posts set and braced to the drawing, the concrete cured before the wires are strained, and the coating left unharmed. SIMO Securon makes chain link in its Alpha, Zeta Nova and Pi grades:

Grade Coating Rated life (C1 to C3, ISO 9223)
SIMO Securon Alpha Zn-Al 90/10, 240 GSM minimum 35+ years
SIMO Securon Zeta Nova Zn-Al 90/10, 120 GSM 20 years
SIMO Securon Pi Zinc, 80 to 100 GSM, with topcoat 10 years

Sites within 20 km of the coast, or chemically aggressive sites, need a site-specific recommendation. To look after the fence: store the rolls dry and off the ground before installation, keep fertilisers and chemicals off the mesh, and walk the line after storms.

Chain link needs a post every 2.5 to 3 m. A high tensile fixed knot fence stands its posts 5 to 6 metres apart, so a long boundary needs around half the posts, holes and concrete. Chain link suits a short run, an enclosure inside a site, or a specification that names it. For how a knotted fence is installed, see the fence installation guide; to see how many posts chain link needs on your boundary, beside a knotted fence, use the fencing cost estimator.

Tell us the boundary length, the height, the ground, the grade, where the fence goes, and whether you want SIMO Securon to install it or to supply your contractor. Add your drawing or specification if you have one, or book a call. For the sizes to ask for, see chain link sizes; for how chain link is quoted, see chain link fencing price.

FAQ

How far apart are chain link fence posts?

Chain link usually needs a post every 2.5 to 3 m, because the woven mesh has no knots to keep it rigid. Terminal, corner and gate posts are braced. A high tensile fixed knot fence spans 5 to 6 metres between posts, so it needs around half the posts.

Fixed knot fence

How long should concrete cure before the mesh goes on?

Keep the concrete damp and wait at least 7 days with ordinary Portland cement (OPC), or at least 10 days with PPC or another blended cement, or in hot, dry weather: the curing periods of IS 456. Straining the wires early pulls the terminal posts out of line.

How many line wires does a chain link fence need?

IS 2721:2025 asks for two line wires up to 2 m high, and three from 2.5 m. They are strained between the terminal posts and carry the mesh, so it stays straight between the posts.

What size posts does chain link need?

It depends on the height, the mesh, the wire and the ground, so the post size, its foundation and its bracing are set on the drawing for each job. Terminal, corner and gate posts are larger than line posts and braced, because they carry the pull of the mesh.

Does SIMO Securon install chain link?

Yes. SIMO Securon's crews supply and install chain link anywhere in India, under one contract. You can also buy it supply only for your own contractor, and SIMO Securon can train that team on site. Larger projects can be taken turnkey.

Is cyclone fence installation the same as chain link installation?

Yes. Cyclone fence is another name for chain link, so it is installed the same way: braced terminal posts, line posts every 2.5 to 3 m, line wires, then the mesh stretched and tied.
