Mar 01, 2018 · Cast steel joints have been widely used in the bridge and ocean engineering such as Aasta Hansteen FPSO spar (Fig. 1(a)) and Hangzhou Bay Sightseeing Tower (Fig. 1(b)) [1,2].The application of the cast steel joints could avoid the welding at the intersection between tubular members, thus prevent the welding defects, residual stresses and thermal deformation caused by welding .
GB/T1591 Q345D Low Alloy High Strength Steel Plate, Coils High-grade Q345D steel plate, steel coil, angle steel, round bar is fully austenitic in nature. These offer excellent corrosion resistance at moist environments. In addition, these resist abrasion due to chemicals in reducing environments. These serve resistance to pitting and crevice cracking even at
Pedestrian Walkway Bridges Excel Bridge Manufacturing
MaterialsDeck TypesWhy Excel Bridge?Additional Resources & ConsiderationsYou have several materials to choose from when it comes to your pedestrian walkway bridge but it all comes down to what is best for your application. Each material has its benefits and restrictions. Here is a brief description of each:Weathering Steel:Weathering steel can be the perfect option in most cases because in can span up to 200 without intermediate supports and provides a nearly maintenance free / natural looking finish.
