SIMO Securon Pi: an affordable knotted farm fence rated for 10 years

SIMO Securon Pi is for farmers and plot owners who need a strong fence now, on a budget, and want it to outlast chain link. It is rated for 10 years, against 2 to 5 years for conventional galvanised chain link (jali) in Indian conditions.

• Farms and plantations losing crops to wild boar (jungli suar), deer and stray animals, at 5 to 6 ft. Pi suits wild boar and smaller animals; for nilgai and cattle, SIMO Securon suggests the Zeta Nova knotted fence or the Alpha knotted fence at 6 ft. See farm fencing and how to protect crops from nilgai and wild boar.
• Commercial plots and general boundaries that need clear, secure demarcation. See plot boundary fencing.

Pi is not made in ZS-Knot (Anti Climb) or above 6 ft. For a factory, solar park or long perimeter, see Alpha, the grade with the longest rated life.

SIMO Securon Pi is rated for 10 years with correct installation. The evidence:

1. Coating. Zinc, 80 to 100 GSM, with topcoat, against 40 to 60 GSM on conventional galvanised wire.
2. Laboratory testing. Tested at NABL-accredited laboratories for tensile strength and coating mass. See how each grade is tested.
3. Salt spray. An estimate, not a test result: about 200 hours salt spray to red rust (estimated from the coating specification).

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

Choose Pi if budget matters most and wild boar or smaller animals are the problem. Choose Zeta Nova for a longer rated life, stronger wire and a zinc-aluminium coating, and for nilgai and cattle.

• SIMO Securon Pi is rated for 10 years, with Q-Knot wire of 850 to 900 MPa and a zinc coating with a topcoat.
• SIMO Securon Zeta Nova is rated for 20 years, with Q-Knot wire of 1150 to 1300 MPa and a zinc-aluminium (Zn-Al) coating. The coating, not the wire, is what gives it the longer rated life.

A Pi fence keeps animals out with Q-Knot, the fixed knot: a separate length of wire is wrapped around every crossing, so the knot cannot slip, and the deep-crimped line wires let the fence spring back after an animal pushes against it. The wires sit closest together at the bottom, where wild boar push, and wider apart at the top.

Pi is made at 5 ft and 6 ft only, in 100 ft (30.5 m) rolls. Pi suits wild boar and smaller animals at either height; where nilgai or cattle are the problem, SIMO Securon suggests Zeta Nova, with its Zn-Al coating, or Alpha at 6 ft.

A square acre is about 255 metres around, so it takes 9 rolls of Pi and about 51 posts (poles) at 5 m. For any field, divide the boundary length by the 100 ft (30.5 m) roll and round up:

At 2.5 metres, conventional galvanised chain link would need about 102 posts for the same acre. 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 Pi’s rated life, and the standard is the same as for every SIMO Securon grade. Posts go every 5 m on 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 QvikFixrr fence posts page.

Your own workers can install Pi: with a supply-only order, SIMO Securon can send a trainer to work alongside them, with instructional videos to return to. Or SIMO Securon’s crews can supply and install it. See fencing supply and installation services.

Over the life of the fence, SIMO Securon Pi against conventional galvanised chain link: Up to 30 percent more cost effective, and it is rated to last longer. Chain link costs less to buy, but it needs a post every 2.5 to 3 metres; Pi needs one every 5 m, so around half the posts, with less digging and concrete.
