Razor Wire Calculator & Barbed Wire Roll Coverage Calculator

How This Calculator Works

Openings are deducted first. Razor wire uses rows and coverage per coil. Barbed wire uses line count and roll length.

• Use Razor only when you need concertina coil quantity.
• Use Barbed only when you need barbed wire roll quantity.
• Use Razor + Barbed when both items are included in the RFQ.

Formula Notes

Effective run: total run length - opening deduction.

Razor coils: effective run x rows x allowance / coverage per coil.

Barbed rolls: effective run x lines x allowance / roll length.
