The structure includes several key components: razor wire, steel posts and frames, choice between chain link fence or anti-climbing 358 mesh fence, gates, and additional accessories.

A.Razor Wire

Raw Materials

Razor wire, a widely used security fencing material, is manufactured from several key raw materials:

  • Steel Core Wire: The core wire is typically made of high-tensile steel. This material is chosen for its strength and flexibility, essential for supporting the razor-sharp barbs and ensuring the wire retains its shape under stress.
  • Metal Barbs or Blades: The razor-sharp elements of the wire are usually made from galvanized steel or stainless steel. These metals are resistant to corrosion, which is crucial for outdoor applications where the wire is exposed to various weather conditions.
  • Galvanization Coating: To enhance durability and resistance to rust and corrosion, the steel core and blades are often galvanized. Galvanization involves coating the steel with a protective layer of zinc. This process extends the lifespan of the razor wire, especially in outdoor and harsh environmental conditions.
  • Stainless Steel (Optional): In some high-end or specialized applications, stainless steel may be used for both the core wire and blades. Stainless steel offers enhanced resistance to corrosion and weathering, making it ideal for use in coastal or harsh industrial environments.

Blade Type

The different blade types for Barbed Tape Obstacles (BTO) and Concertina Barbed Tape (CBT) each have their specific features and general dimensions. These types are designed for various security needs and settings. Here’s a detailed look at each:

  • Blade Thickness: Usually ranges from 0.5 mm to 0.6 mm.
  • Material: Typically made of galvanized steel or stainless steel.
  • Spacing: Blade spacing can vary but is often around 25 mm to 100 mm apart.
  • Coil Diameter: Varies based on type, generally between 450 mm to 980 mm for concertina types.
  • BTO-10(Barbed Tape Obstacle)
    Blade Length: 10 mm
    Designed for low-security applications
    Shorter blade length offers a basic deterrent
  • BTO-18(Barbed Tape Obstacle)

    Typically employed in military and high-level security areas
    Very large blades for maximum deterrence and injury potential
  • Nots: Can be installed atop walls or fences, or laid on the ground in a concertina coil format. Each blade type is designed for specific security needs, with the choice depending on the level of deterrence required. The larger and more aggressive the blade, the higher the level of security and injury risk it presents, making it suitable for more sensitive or high-risk areas.

B. Steel Posts and Frame

The structure of a frame steel fence, especially when designed to support razor wire, consists of several key elements, each with specific dimensions for optimal functionality and security. The common dimensions, expressed in millimeters (mm), are as follows:

  • Material: Typically made from galvanized or stainless steel, known for rust and corrosion resistance. While steel is common, other metals can be used. Steel frames typically have a thickness of 2 mm to 4 mm.
  • Supporting Posts and Brackets: These are used to install and support the razor wire at the top of the fence and gates. They must be strong and durable to hold the weight and tension of the razor wire.
  • Vertical Steel Posts: The main support structures. Their thickness can range from 2 mm to 4 mm, and their height varies based on application, often between 2000 mm to 3000 mm.
  • Horizontal Framing: Connects the vertical posts, with a typical thickness of 2 mm to 4 mm and length depending on the fence width.
  • Y Fence Post: The Y post top has a ‘Y’ shape, specifically designed for razor wire fences. Increases security by making it difficult to gain a grip or foothold. The Y-shaped top supports razor wire. The ‘Y’ portion usually extends 100 mm to 200 mm above the main post, with arms extending outwards by approximately 150 mm to 250 mm.
  • Corner Posts: Stronger and often larger than regular posts, corner posts provide additional support at the corners of the fencing, where tension is highest.
  • Nots: The frame’s function is to keep the razor wire effectively stretched and in place. The thickness and strength of the frame are adjustable; higher security areas require steel of greater thickness and strength. While common dimensions exist, they can be customized to meet specific security needs and environmental conditions.

C. Steel Fence Panels

Generally, razor wire fence is often used in conjunction with a chain link fence or an anti-climbing 358 mesh fence. This combination enhances security by pairing the deterrent effect of razor wire with the robust physical barriers provided by chain link or 358 mesh fencing.

  • Chain link fences are a popular choice for both residential and industrial areas due to their durability and cost-effectiveness. The two common types are: Standard Galvanized Chain Link Known for its durability, this type is widely used for boundary and security fencing. Its galvanization process makes it resistant to rust, making it a practical choice for various settings. PVC-Coated Chain Link type adds extra durability and aesthetic appeal to the standard chain link fence. The PVC coating not only enhances its resistance to weathering but also allows for a variety of color options. It’s commonly used in residential areas and public spaces for both security and visual appeal.
  • Anti-Climbing 358 Mesh, also known as “358 mesh fencing” or “prison mesh,” is a high-security fencing designed to prevent unauthorized access, ideal for prisons, military bases, airports, and industrial sites. Its name derives from its mesh pattern, with a 3″ (76.2mm) x 0.5″ (12.7mm) aperture and 8 gauge (4mm) wire diameter, ensuring a robust and durable structure. The small mesh openings effectively deter climbing, crucial for high-security facilities. While primarily used in prisons and military installations, its use has expanded to transportation hubs, power plants, and commercial areas requiring enhanced security.

D. Fence Gates

Razor wire fence gates, crucial in high-security fencing systems, are typically made from the same durable metal as the fence, often reinforced with additional razor wire layers for enhanced security. Available in various designs like swing and sliding models, they suit different entry types and operational needs. A key feature is the integration of razor wire at the top or other parts of the gate.

  • Material and Design: Made from strong metal, gates are often reinforced with razor wire. Swing gates and sliding gates vary in size, typically ranging from 1000 mm to 4000 mm in width for pedestrian and vehicle access.
