Special welding techniques allow the production of thin and very light stainless steel sandwich panels with a wide range of potential applications in the shipbuilding industry. A three-dimensional truss-core is built up between top and bottom steel plates. The symmetric construction of the COREX panel allows an even load distribution in all directions. The panel elements are fitted with special end-fittings and welded together into larger sections. The first application now being introduced to the market is to use the COREX panels from MacGregor - the world's leading supplier of equipment to RoRo vessels - for fixed and hoistable car decks/ramps. As well as newbuilding installations, car decks based an COREX panel construction are particularly suitable for RoRo conversions. Car decks built from COREX panels have substantially reduced profiles and are about half the weight of conventional car decks. These advantages offer considerabie design freedom in terms of reduced lightship weight, reduced moulded depth and increased stability. Due to the manufacturing method the deck surface is very flat, smooth and without welding deflections. The primary advantages with a deck built from COREX panels are: (1) Low profile, of only 100 mm, (2) low weight, (3) flatness, (4) practically maintenance-free, and (5) shorter delivery time because of COREX modularity. Production of the COREX panels and fittings is carried out in a specialist MacGREGOR workshop. All material/components are within container size limits allowing low cost shipments for longer delivery distances. The car decks can be shipped pre-assembled or alternatively the final assembly can be carried out close to the customer. Technical data for a COREX panel car deck are given as follows: (1) Total structure depth: 100 mm, (2) total structure depth with clearance and deflections in stowed position: 100 mm to 140 mm, (3) total structure depth with deflections in working position: maximum 140 mm, (4) steel weight for fixed car deck: 0.45 kg/m2, (5) complete weight with fittings and hydraulic cylinders for hoistable deck: 0.52 kg/m2, (6) maximum distributed cargo load on deck: 200 kg/m2, and (7) free span at maximum load: 7 m.
