Industrial fencing for factory boundaries, warehouses and data centres

Conventional galvanised chain link costs little at the outset, but its woven diamond is easy to cut and climb and it corrodes in 2 to 5 years. A compound wall resists climbing, but it means heavy civil work and a long build. Where the need is privacy or screening rather than security, a wall is the right answer.

Where a long industrial boundary faces animals rather than people, a Zeta Nova Q-Knot fence suits it; keep the 4 x 2 inch anti-climb grid for the stretches where people climbing in is the threat.

For factories, data centres and other high-security sites, SIMO Securon proposes the ZS-Knot (Anti Climb) knotted fence on the 4 x 2 inch grid, in Alpha, up to 8 ft, with RTHT barbed wire and concertina coil, surveyed and installed as one package. ZS-Knot in Alpha is rated for 35 years or more; in Zeta Nova, 20 years.

Only the 4 x 2 inch ZS-Knot grid is anti-climb: its stays sit 2 inches apart and its line wires 4 inches apart, so the openings are too narrow for a toe or finger hold. The 4 x 4 inch uniform grid and the 3 x 3 inch close grid are not anti-climb.

SIMO Securon makes ZS-Knot at 6 ft as standard, also at 5 ft in Zeta Nova, and up to 8 ft to order. A 6 ft fence fits the standard QvikFixrr 8.5 ft post with attachments for a topping; an 8 ft fence needs custom posts, made for fence supply orders of 2 km running length and above. The height is suggested after the site survey.

A complete ZS-Knot perimeter is the fence fabric plus QvikFixrr posts, clips, fabric locks and fasteners, RTHT reverse-twisted high tensile barbed wire and QvikFixrr concertina coil, supplied together as one matched system.

For security perimeters, SIMO Securon usually works as supply and install, or turnkey EPC:

1. Site survey: boundary length, levels, gates, existing walls and the threat you face.
2. Design to the drawings agreed with you: grid, height, topping and post layout.
3. Supply of the complete system: fabric, QvikFixrr posts and fittings, RTHT and concertina coil.
4. Installation by trained crews.
5. Inspection, then handover with documentation.

Lead times: About 7 days for standard rolls and 30 to 45 days for custom projects, from order confirmation. An 8 ft fence on custom posts is a custom project.

See fencing supply and installation services for supply only, with training for your own contractor.

SIMO Securon does not publish prices: they depend on the boundary length, height, grid, grade, toppings and terrain, and on whether SIMO installs the fence. With posts 5 to 6 m apart, the installed cost of a SIMO Securon perimeter comes out in line with conventional galvanised chain link, and installation runs around 40 percent faster. Chain link costs less to buy and suits low-risk boundaries; where people climbing in is the threat, specify the 4 x 2 inch grid.
