Overview
Products are engineered according to their intended location and function, including exposed decks, tanks, machinery areas, cargo zones, service platforms and restricted-access compartments. The final design is established based on approved drawings, operational loads, environmental exposure, required tightness and the applicable project or classification requirements.
Depending on the application, equipment can be supplied as individual components or as complete assemblies incorporating frames, covers, hinges, locking mechanisms, seals, supports and installation accessories.
