358 Mesh Hot Dip Galvanised Steel Security Fencing to Secure Perimeters

Anti Climb 358 Wire Mesh finds predominant use in fencing systems designed to bring maximum perimeter protection to a site. This style of mesh is universally accepted as the most secure form of high security welded mesh panel. 358 Mesh Fencing has significant inherent advantages over products such as chain link fencing or other forms of welded mesh fencing owing to its unique configuration. With razor wire coils above mesh panels, 358 mesh makes ideal port boundary perimeter fence.

358 high security mesh is supplied in a varieties of materials:

358 mesh panels hot dipped galvanised;
358 panels made from Galfan/ Bezinal (Zinc Alu) wire;
358 galvanized and powder coated perimeter security fencing panels.

Exported to:
Portugal, UK, Saudi Arab and other countries.

This system to be linked to the perimeter CCTV cameras and give an exact location of the trigger incident to the Security Control Room.

Gate Posts

Gate posts shall extend above the ground to match the height of the adjacent fence, and shall come complete with galvanised hinge pins and baseplates (These items shall be galvanised after assembly, but before arriving on site)

Any gap between a boundary wall post and a gate post shall be covered with a three-layer coil of galvanised razor wire.

Internal Boundary Fences

Internal Boundaries Fence

Internal fencing complies with the provisions of the Specifications and in particular BS 1722 Part 10: Specification for anti-intruder fences in welded mesh.

The internal fencing is Securimesh or similar. It is consisted by posts that are centred every 2.45m and has a height of 2.44m. The mesh centres shall be 76.2 by 12.4mm by 4mm thick. The foundations are constructed by concrete having minimum foundation sizes 300mm by 250mm by 900mm deep.

Posts are of circular hollow section suitable for heavy duty mesh as per Table 2 of BS 1722 Part 10 and the manufacturer’s recommendations. Posts galvanised with minimum dimensions 80mm x 60mm.

Intermediate straining wire restraints are installed at 1/3 points between the support posts securely concreted into the ground.

Temporary Fence in Chain Link or Weld Mesh

Temp chainlink fence extends from not more than 50mm above the top of the fence wall to a minimum height of 2.5m above ground level. Wire core diameter 3.5mm minimum diameter and wire size overall 4.75mm minimum diameter, mesh sides 50mm maximum.

The mild steel wire galvanised prior to the application of a bonded PVC coating. Mesh secured to top and bottom line wires with wire ties at maximum 150mm centres and to intermediate line wires at maximum 450mm centres, and then strained and secured at not less than 2.515 m centres by means of stretcher bars threaded vertically throughout the height of the mesh.

Galvanised ‘studding’ required for fixing the wire and not greater than 400 mm centres. The lower line wire is threaded through the mesh and a galvanised clamp plate. The plate is fixed to the fencing wall by nuts and washers located on the inside of the fence.

Line Wires to Mesh

The top “line wire” consists of two wires, one threaded through every other mesh, the other unthreaded. At least three other unthreaded line wires are provided below the top wires and equally spaced, the bottom wire being approximately 50mm above the bottom of the mesh.

All wires are galvanised mild steel sized in accordance with the fence manufacturer’s recommendations.

All line wires are attached to support posts by wire stirrups passing through holes in the posts, and strained at each straining point by means of winding brackets.

Straining carried out in accordance with the fence manufacturer’s recommendations.

Fence Gates

Internal Gates

Gate details for the internal boundariescomply with BS1722: Part 10, typically the gates are commensurate with the adjacent fencing, and are swing opening.

Gates are formed form circular hollow sections and shall be sized to suit the opening width. For openings over 2m width double leaf gates shall be used. Gate posts shall be from RSJ or UC sections as per Table 3 of BS 1722 Part 10.

A concrete gate sill of minimum size 250mm × 450mm deep is provided between gate posts, with the top surface at ground level and cast in sleeves for drop bolts. Adjacent surfacing is fully reinstated on either side of the sill.

Entrance Gates

Gate frames fabricated from rolled steel angle with mild steel panels, welded to the frame. Open panels are left clear of steel panelling. Mild steel bars 16 mm diameter minimum are welded across these open panels at not greater than 100 mm centres.

Each gate is topped with 3 lines of barbed wire and coiled razor wire fixed to extension arms on stiles and vertical braces. All steel shall be galvanised in accordance with BS EN ISO 1461. Where local limitations apply to galvanising, the gate may be galvanised in sections and assembled using galvanised bolts, nuts and washers, the bolt shanks being buried over after assembly to prevent loosening.

Single gates are used to fill openings up to 2m in width and double leaves of equal widths to fill openings up to 10m in width.

Gates are side hung vertically to give not greater than 50mm ground clearance at the meeting point. Double gates have 12mm maximum gap between meeting stiles. Sleeves for drop bolts shall be provided cast into a concrete sill.

The gates are provided with a vertical drop bolt on each leaf, a sliding bar lock with padlock eyes and a seven lever galvanised padlock with duplicate keys.

All hinges and other moving parts are greased before assembly and the whole gate securely supported whilst being assembled in position.

Gate House

A gatehouse is provided in the location given.

The floor level in the gatehouse shall be elevated such that the staff are at the same level as the truck drivers.

The building shall have an air conditioning system that maintained to a positive air pressure to prevent ingress of vehicles fumes into the gatehouse.

Windows to be fitted with security shutters.

Concrete Gate Sills

A concrete gate sill of minimum size 250 × 450 mm deep provided between gate posts, with the top surface at ground level and cast in sleeves for drop bolts. Adjacent surfacing is fully reinstated on either side of the sill.

Vehicle Gates

Vehicle gates are provided, as an automatic rising arm barrier with a bottom skirt. Operated manually and electrically.

Gates are constructed to match the height of the adjacent fence and manufactured from the same size steel tubes and mesh.

The bottom of the gates have a ground clearance of no more than 80mm. When closed, the space shall be not more than 25mm between the meeting stiles.
