Blade Barbed Tape Parameters(1)

Blade barbed tape parameters primarily cover material, structure, dimensions, and protective performance. Here is a detailed breakdown:

I. Material Parameters

ape Material (Blade Material)

Hot-dip galvanized steel strip:Common thicknesses are 0.50mm and 0.55mm, made from Q195 or Q235 steel strip. Offers good strength and economy, suitable for ordinary environments.

Stainless steel strip: Such as 304 or 316 stainless steel. 304 stainless steel contains Cr 18%-20%, Ni 8%-10%, suitable for moderately corrosive environments; 316 stainless steel adds Mo 2%-3%, providing stronger corrosion resistance for coastal or industrial areas.

Plastic-coated steel strip:** The steel strip surface is coated with PVC (Polyvinyl Chloride) or PE (Polyethylene). PVC coating is wear-resistant and anti-aging, while PE coating has better low-temperature flexibility.   Coating thickness is typically 0.15-0.30mm.

Core Wire Material

Hot-dip galvanized steel wire: Diameters commonly include 2.2mm and 2.5mm. Zinc coating weight is generally above 60g/㎡ (standard grade) or above 90g/㎡ (heavy duty grade), providing good rust prevention.

Stainless steel wire:Typically matches the tape material, such as 304 or 316 stainless steel wire, offering overall corrosion resistance.

II. Structural Parameters

Blade Shape and Arrangement

    Blade shape: The main shapes are BTO (Twisted Blade - commonly spiral or linear twist) and CBT (Straight Blade - commonly flat, not twisted). Specific shapes include:

    BTO-22: Blade width 22mm, blade length 15mm, longitudinal spacing 34mm.

           BTO-60:Blade width 60mm, blade length 25mm, longitudinal spacing 100mm.

           CBT-65: Blade width 65mm, blade length 25mm, longitudinal spacing 100mm.

    Arrangement method:Blades are punched and formed from the steel strip, which is then twisted (for BTO type) or kept flat (for CBT type) and wound around the core wire(s) to form a spiral structure. The number of core wires is typically 3 or 4 for BTO-60/CBT-65, enhancing stability.

Coil Structure

• BTO type: After twisting, the blades point in different directions, forming a dense, sharp barrier. The coil diameter after closure is usually 450mm, 500mm, or 600mm.
  
• CBT type: The blades are not twisted and remain in the same plane, forming a sharper, knife-like cutting edge. The closure diameter is typically 500mm or 600mm.
