Security Palisade Fence – High Security and Stability Steel Fencing

Security palisade fencing, also called SP fence, is made from S235JR and it increases the difficulty to go through buildings. Compared with general palisade fence, SP fence has higher security and stability. SP fence only involves 3.0 mm thick corrugated W" section and 3.9 mm thick corrugated "D"section, not refers to steel angle. Besides, the height of the fence can be 3.0 or 3.6 m above ground. SP fence often used to protect schools, parks, churches, stadiums, industrial sites, railways, highways, premises, yards, companies and so on.

Specifications of security palisade fence:

• Material: hot or cold formed S235JR.
• Composition: pale, rail, post, and fittings
• Pale:
  • Pales section: corrugated "W"section 3.0 mm thickness, corrugated "D"section 3.9 mm thickness.
    • Triple head corrugated "W" section is often used for high security palisade fencing.
    • Corrugated "D" section is used for medium and low security palisade fencing.
  • Corrugated pale top shapes: round and notched; round only; plain; single pointed; triple pointed and splayed; triple pointed; splayed and returned.
  • Pales deflection: not exceed 10 mm at the middle of the span under 3.5 kN load.
  • Spacing of pales: 155 mm.
  • Width: 70 mm.
• Rail:
  • Rolled steel angle section.
  • Security palisade fences have three horizontal rails.
  • The bottom one rail should be located above 100 mm from the bottom of the pale.
• Pale to rail fixing methods: welding, bolting or riveting
• Post to rail connections: bolting, welding or slotting.
• Holes for fence post foundations:
  • Square hole (mm): 450 × 450.
  • Round hole (mm): 600 diameter.
• Addition security:
  • Burrowing:
    • Pales shall be extended by 150 mm and embedded in the concrete sill.
    • Pales shall be extended by 350 mm and buried in the ground.
  • Topping:
    • In order to gain higher security level, the top of the security palisade fence can install barbed wire and razor wire.
    • Besides, the security palisade fence also can be used by combining with small opening mesh fence, such as 358 mesh, expanded metal, and so on.
• Fittings: bolts, nuts, washers, cold swaged pin, hinges, drop bolt and slam plates, locking devices, fastenings.

Characteristics of security palisade fencing:

• High security.
• High durability and stability.
• Beautiful.
• Corrosion resistant.
• Easy to install.
• Easy to maintain.
• Long service life.

Various applications:

• Schools.
• Parks and churches.
• Stadiums.
• Industrial sites.
• Railways and highways.
• Premises, yards and companies.
• Access to buildings, sports and other facilities, etc.

Packaging:

• First, the pails, rails and posts are packaged separately by strings and in plastic films, then packaged on wooden pallet or steel pallet.
• All of fittings are packaged in box.
• In addition, the fence also can be packed in bulk.

Maintenance:

• Fence maintenance:
  • If necessary, the user can use soap and water to wash the palisade fence and gates.
  • Please don't use abrasive materials, for they will damage the protective surface of fence.
• Gate maintenance:
  • Ensure the bottom rail and stile locking bar is secure and intact.
  • Inspect the fixings and grease pins (hinges).
  • Check the gate is adjusted correctly and moves freely.
• Coating maintenance:
  Paint coatings usually need a redecoration cycle of 3 to 8 years.

Service life:

• The service life of security palisade fencing is usually between 10 and 30 years.
• In addition, the corrosive of the atmosphere where the fence is located and the difference of paint coatings influence the service life of security palisade fencing.
• In terms of coating, PVC has a stronger corrosion resistance than galvanized coatings.
