Steel structure floating bridge, use similar structure frame with aluminum alloy floating bridge, but the material USES Q235b or Q345 steel mainly.Its advantage is that the structural strength is higher than the aluminum alloy, and the cost is relatively cheap, the disadvantage is easy to rust corrosion and the high maintenance cost.As for stainless steel material, basically few people use stainless steel as the main structure,first reason is the price of stainless steel material is more expensive than aluminum alloy, the second reason is the seawater corrosion resistance is not stronger than aluminum alloy. STEEL PONTOON Large steel pontoon, similar to the structure of traditional barges.We innovate on the traditional structure to make a new kind of steel pontoon bridge.weizhou project Network bonding
