SIMO Securon Zeta Nova: a 5 or 6 ft knotted fence rated for 20 years

SIMO Securon Zeta Nova is for farms, plots and boundaries that need a fence to stop animals and to last. It is rated for 20 years, on the same high tensile wire as the Alpha knotted fence, with half Alpha’s minimum coating mass.

• Farms and plantations losing crops to nilgai (blue bull), wild boar, deer and stray cattle. For nilgai and cattle, SIMO Securon suggests Zeta Nova or Alpha at 6 ft; the graduated grid’s tight lower wires stop boar and small animals. See farm fencing.
• Plots, farmhouses and estates: a 5 ft Zeta Nova fence on QvikFixrr fence posts marks and secures the boundary without the civil work of a compound wall. Add RTHT barbed wire on top where security matters. See plot boundary fencing.
• Solar farms and industrial perimeters where a 20-year rated life fits the project, including the ZS-Knot 4 x 2 inch anti-climb grid where people are the threat. See solar plant fencing and industrial fencing.

SIMO Securon Zeta Nova is rated for 20 years with correct installation, against 2 to 5 years for conventional galvanised chain link (jali) in Indian conditions. The evidence:

1. Coating. Zn-Al 90/10, 120 GSM, with no wax topcoat: two to three times the 40 to 60 GSM on conventional galvanised wire. See how a zinc-aluminium coating protects steel wire.
2. Salt spray. Tested to 1,200 hours salt spray without red rust.
3. Laboratory testing. Tested at NABL-accredited laboratories for tensile strength (IS 1608, Part 1) and coating mass and adherence (IS 6745). See which tests apply to Zeta Nova.

The rated life holds with correct installation: posts free of rust, braced corners and ends, tension applied only once the concrete has cured, rolls stored dry before fitting, and fertilisers and chemicals kept off the fence.

Rated life by product

Product	Rated life
SIMO Securon Alpha	35+ years
SIMO Securon Zeta Nova	20 years
SIMO Securon Pi	10 years
RTHT barbed wire, Zeta Nova grade	15+ years
Conventional galvanised chain link	2 to 5 years

Zeta Nova sits in the middle of the SIMO Securon range. It uses the same Q-Knot wire as Alpha, 1150 to 1300 MPa, with half Alpha’s minimum coating; against Pi, it has stronger wire and a zinc-aluminium coating in place of zinc with a topcoat.

• Choose Zeta Nova for most farms, plots and farmhouses, and for 5 ft or 6 ft fences that must last. SIMO Securon Zeta Nova is rated for 20 years.
• Choose Alpha for a long perimeter around a valuable asset, where replacing the fence mid-life is not an option. SIMO Securon Alpha is rated for 35 years or more.
• Choose the affordable Pi grade if budget matters most and wild boar or smaller animals are the problem. SIMO Securon Pi is rated for 10 years.

Zeta Nova is made in 5 ft and 6 ft as standard, and to order up to 8 ft, in both SIMO Securon technologies: Q-Knot keeps animals out, and ZS-Knot keeps people out.

Choose the height by what you are keeping out: at least 6 ft for nilgai and cattle, 5 to 6 ft for wild boar and smaller animals, and 8 ft for a forest or wildlife boundary. An 8 ft fence needs custom posts, made for fence supply orders of 2 km running length and above.

A square acre is about 255 metres around, so it takes 9 rolls of Zeta Nova and about 51 posts at 5 m. Divide the boundary length by the 30 m roll and round up:

Bracing for the corner and end posts comes on top, and long, narrow fields need more fence for the same area. The fencing cost estimator works out the rolls and posts for your land, and fencing cost per acre explains each step.

Correct installation is a condition of Zeta Nova’s rated life, so SIMO Securon recommends supply and install by its trained crews. If your own workers install, SIMO Securon can send a trainer to work alongside them on tensioning, bracing and fixing, with instructional videos to return to. Posts go every 5 m on QvikFixrr GI angle posts, terminal and corner posts are braced in concrete, and the fence is tensioned only once the concrete has cured. Post sizes and foundation depths are on the fence posts and fittings page; the ways to buy are on fencing supply and installation services.

Over the life of the fence, SIMO Securon Zeta Nova against conventional galvanised chain link: 10 to 20 percent more cost effective, and twice the life. Chain link costs less to buy, but it needs a post every 2.5 to 3 metres; Zeta Nova needs one every 5 m, so a boundary needs around half the posts, with less digging and concrete.
