Northern Stock Water specialises in water development and irrigation products for farms, cattle stations and mines. Elsam Plastics is an Australian Standards-certified brand of metric and rural polyethylene pipe. The company wins contracts throughout northern Australia. It was the first company in the Northern Territory to produce concrete cattle troughs. To supply a complete product range, it started selling the parts needed to fit the troughs, such as poly and steel fittings, PE compression fittings and float valves. The company then imported a pipe manufacturing machine from Germany and started producing quality poly pipes in its NT factory.
