Quadrant engineering focuses on the design, fabrication/manufacture and installation of components, machinery and specialised equipment. some of this equipment includes electricalswitchgear, lashing screws, refuse bins and pallet inverters. We prefer never to compromise on quality. One of our first products was a specific type of lashing screw designed for the shipping industry. We tested the screws against a chinese version and found that they broke at 7.8 tons where ours broke at 14 tons, almost double the weight.
