Key Components of Hi Secure 476 Components

Posts
Hi Secure 476 is designed to secure properties of varying scales, with its name in-spired by its hollow steel posts. These posts come in measurements of 50x50mm, 60x60mm, or 50x100mm, depending on the fence's height, providing the necessary strength to withstand pressure and force. The posts determine the fence's length and offer several mounting options:
- Over-length set in the ground
- Base plated for bolting onto concrete
- Cranked for wall mounting
- Covered with a plastic cap on top
- Extended with a 45-degree crank on top
- Extended with a double (Y) crank on top
Panels:
The mesh between the posts is known as a panel. These wire mesh panels are 2500mm wide, made with 4mm/5mm vertical and horizontal wires welded together, forming rectangular openings of 76.2x12.5mm with a special 2D profile for additional reinforcement. The standard panel heights are 950mm, 1450mm, and 1950mm, and can be stacked to create a fence up to 6000mm high.
To enhance security and prevent climbing, options include:
- 30mm projecting spikes
- 3 or 6 barbed wires
- 3 or 6 barbed wires with a concertina role
The tensile strength of the wires is a minimum of 500 N/mm², with the welding strength at least 50% of the total tensile strength of the wire, in compliance with EN 10223-7.


Fittings
The system uses rigid 40x50mm metal clips or 50x5mm flat bars along the full length of the post to secure the welded steel mesh panels. These fittings are bolted every 400mm using 8mm diameter round head bolts.
Gates
Matching single leaf and double leaf gates are available for the Hi Secure 476 fenc-ing system. These gates come with a variety of opening mechanisms and can be man-ually or automatically operated.

Finishing Options
Hot-Dip Galvanizing
All steel components shall be hot-dip galvanized in accordance with BS EN ISO 1461 to ensure superior corrosion protection and extended service life.
Powder Coating
For enhanced durability and aesthetic finish, components shall comply with BS EN 13438, involving hot-dip galvanizing followed by a high-quality powder coating process.
Marine-Grade Protection
For installations within 500 meters of saltwater or estuaries, a specialized marine-grade coating system shall be applied to provide robust resistance against salt-induced corrosion.
