Packing of Concertina Razor Wire from skyhall fence

The packing concertina razor wire need a lot of labor because each of the concertina razor wire coils is packed independently. The independently package is very necessary because of the shape razor blade will be crossed and can not be separated if the razor tough together. First, need to pack the concertina razor wire with water proof paper. The water proof paper can prevent the water go into the concertina razor wire coil if raining. Then wrapped the coil with plastic belt. The plastic belt is to prevent people’s finger from cutting when they carry it because of the blade is really sharp and dangerous. All these packing process need to be done by labor. After the plastic belt wrapped, we need to press a lot of concertina razor wire coils to be a bundle to save space for increasing loading capacity. Also the bundle can be much easier for folklift loading. Loading in bulk is also acceptable, but only suggest do loading in bulk when small quantity, or the loading capacity will be very small. (1)In Bulk: loading the concertina razor wire coils in bulk. (only suggested in small quantity) (2)Water Proof Paper inside + Plastic Belt outside + Press to Bundle: wrapped the water proof paper inside then plastic belt outside, press the coils in bundles. (suggested)
