Dolphin Beam Fabrication Underway at Strubeam for Project in Wales

Our project in Wales is taking shape at our East Kilbride Strubeam facility with the fabrication of these 12.5te plated Dolphin beams formed out of 60mm*450mm wide flanges and 20mm thick web plate; all S355 steel. The 10No. Dolphin beams will cantilever 9m from plate girder columns and will support approx. 35Te of concrete terracing which will form the upper tier. The connection to the plate girder column is designed as rigid non-slip connection with M36 grade 10.9 Tension Control Bolts, 80mm thick inside flange plates and 15mm thick web plates. Connection back to the concrete core is achieved via a stub section matched to the dolphin beam geometry that is welded to the cast-in plates connected together with 22No. M36 grade 8.8 bolts and 40mm thick endplates. The fabrication of the dolphin beam involves single sided full penetration butt welding between the flanges and fillet welds to the stiffeners and web section.
