§1What this business is
GI strip is punched on a power press into barbed tape, crimped onto GI core wire and wound into coils of 2 ft, 2.5 ft or other diameters, then clipped into a spring form. The coils stretch out into an instant fence. Buyers are builders, factories, warehouses, farms, nurseries, railways, airports, defence and other government sites.
Capacity: 100 rolls a day, 30,000 rolls a year at full capacity (8 kg of raw material per roll). The report plans 50% use in year 1 rising to 70%.
