The word steel, whether ordinary or lightweight 16mn beam, since the cross section dimensions are relatively high, narrow beam 20, so the cross-sectional moment of inertia of larger difference between two spindles wholesale beam, it can only directly for flexural member in its web plane or lattice consisting force member. For axial compression members or perpendicular to the plane of the web as well as curved components are not suitable, which it has significant limitations on the scope of application. Steel water gate is hydroelectric power stations and reservoirs to control water main steel structure, it will be part of long-term immersion in water beam, surface erosion by microorganisms (such as adsorption nail scorpion, which is acidic excrement). Another part of long-term exposure to the atmosphere, especially the waterline, surfing and water impact on floating debris, but also by the high tide, low tide influence, make this part of the steel surface regularly alternating wet and dry, are particularly vulnerable to rust. Now using wire spray zinc, aluminum spray process, greatly improve the corrosion resistance of the steel gate, anti-corrosion life than the original paint process employed increased by 5 to 6 times.
