Steel structure design, Peng Jian steel (certified), Shenzhen, Dongguan City, the steel structure is provided by Peng Jian Steel Limited. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) is specialized in the "Steel" business, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Xu. Steel structures attic should find the best professional before making a few points to note about the loft attic loft designed steel structure design. Construction to determine the level a little, lay horizontal, press construction. Attic steel material used to determine the price of steel, (span of more than 3.5 meters. The best use GB steel). Some unprofessional attic square steel company owners do recommend undesirable (inside and outside the steel can not fully rust. Easily oxidized steel contractor, relatively thin) should correct channel or beam. If the improper selection of steel, after the completion of the whole loft will flutter, white will crack. Construction to determine the level a little, lay horizontal, press construction. If the walls are hollow brick, the best overall channel lying in the wall 10 cm, both sides must be added to the column. Attic steel channel. Angle laying most plus size 610mm * 610mm Steel, based blockboard 1.22 m * 2.44 m given. Otherwise it will waste a lot of the board. Channels and angles must be welded in a plane. In the channel bottom welding, when the board will put the burden of not real, after soldering is absolutely necessary level. Cutting corners is best to use the slot and plug sockets method, flat, vertical-sided welding, rust is also very important, just the structure of the package inside to absorb moisture easily, San tide difficult (especially the bathroom above the attic). Best to make a change before making steel rust rust treatment after a good brush, must take the doors and windows open to maintain ventilation, the toxin paint exhausted weaknesses intensify propaganda in recent years, in the world there were several large destructive earthquake, so that the most important advantage of steel construction - seismic performance - stand out. However, a problem can not be avoided, steel residential construction costs are indeed higher than the concrete building. From the actual situation in China, the promotion of post-disaster reconstruction in steel residential recovery of the local economy is no pulling power of large concrete building, because steel housing is factory production, assembled at the construction site, you can save a lot of labor. In addition, for the building, as long as the country can achieve the release of seismic standards is safe, not because of the occurrence of the "5.12" Wenchuan earthquake, we put the building seismic standards too high, you want to build for our country conditions of residence. Japan, the United States of seismic standards of buildings higher than ours, which is determined by the state power. On the other hand is not because steel compression resistance, tensile strength is very good, an earthquake and other natural disasters; Japan, the US steel residential occupancy is relatively high, partly because they have strong economic strength brittle destruction, and the concrete structure will produce brittle fracture, and can not be reused. Steel residential important reason is not yet universal in our country is that people know little about. People do not care whether the steel residential industrial production, they are more concerned about building safety and comfort. Many people do not come into contact with steel housing, coupled with propaganda is not, leading them to believe that steel residential home uncomfortable.
