Steel plant how to corrosion? Steel design requirements indicated in the intensity level of steel, connecting material models steel plant maintenance, form and weld seam quality level and construction requirements. A grade of steel is not guaranteed impact toughness, the carbon content of omission delivery conditions, it can not be used for earthquake-proof and welded structures (This statement is not accurate, but the design people can accept, in fact, can not weld or solder, is the carbon equivalent decision rather than carbon content); in the actual project, in addition to the lower flange large span heavy duty crane girder steel butt and docking of large-span steel bridge tension member of this high quality requirements require a weld seam, other occasions rarely used one. Generally require two. For fillet welds, except in the case of penetration requirements (eg for a large fillet wheel pressure on the crane beam flange and web connections), its quality grade requirements two outside, usually with three other occasions level. First, steel residential building energy than conventional buildings to better meet the requirements of large bays separated by flexible, and by reducing the cross-sectional area of ??the column and the use of lightweight wallboard, improve area utilization, effective use of the indoor area increased by about 6 %. Second, the energy saving effect, using light energy saving wall standardized C steel, good steel, sandwich panels, insulation properties, good seismic degrees. Saving 50% of professional steel plant maintenance, three, the steel structures for residential buildings can take advantage of the ductility of steel, plastic deformation ability, with excellent wind seismic performance, greatly improving the safety and reliability of residence. Especially in the event of an earthquake, typhoon disaster case, steel buildings collapse can be avoided destruction. Fourth, the total construction light weight, light weight steel structure residential system steel plant processing factories, about half the concrete structure can greatly reduce the cost basis. Fifth, the construction speed, shorten the construction period than the traditional housing system, at least one-third of a 1,000 square meters just 20 days, before the completion of five workers.
