Electrolytic steel plate is a kind of high quality metal material, the surface is smooth, flat, not easy to damage. Manufacturers in advance to be built in the place after investigation, according to the specific situation, the site to measure the size of the blanking, blanking in the production workshop, and then shipped to the site. Then the pair into the seat, the plate will be welded in the steel keel, joint site lighting. At the same time, all kinds of equipment will be installed into the reserved space of the steel keel. The surface coating of the plate is carried out on site. After the coating solution volatilizes to a certain extent, the clean operating room can be used normally. The operating room built by electrolytic steel plate is flat and smooth without lines. It is often made by welding multiple steel plates, with good air tightness. But, must want to consider the maintenance to circuit, gas conduit henceforth, because this wants to install maintenance cabin door, in square steel keel between, leave enough space, so that maintenance personnel passes. And, because the steel plate is heavier, so the overall structure, the building bearing requirements are also high.
