Plants
Safety is our number-one priority in the field of process engineering.
Joining elements that are used in power stations or refineries are not only subjected to maximum loads, they are also tremendously significant for the safety of the plant as a whole, as well as its environment. GLF produces and supplies special joining elements for the chemical industry, for plant engineering and for industries specialising in the construction of fittings, pipework, apparatus and receptacles, as well as for power stations and refineries. Our manufacturing programme includes screw and threaded bolts, double-ended studs, hexagon-head cap screws and hexagon-socket screws, parts manufactured according to drawings, as well as the relevant nuts and washers. These products are designed according to either DIN, ASTM or to customer specifications Application market:
