Peng Jian Steel (map), steel production, steel supplied by Henan Peng Jian Steel Co., Ltd., Dongguan City. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) Guangdong Dongguan, steel leader, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Peng leader in steel construction with the staff warmly welcome all inquiries negotiations to create Peng Jian Steel a better future. 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. Steel material used to determine the attic, (span of more than 3.5 meters. Preferably with GB steel). Some do not recommend owners of professional attic with square steel companies do not desirable, (inside and outside the party can not fully rust-proof steel. Easily oxidized, relatively thin thickness) should correct channel or I-beam. If the steel improper selection, after the completion of the whole attic will flutter, white will crack. In that determine the level of steel construction metal housing, lay horizontal, press construction. As the walls are hollow bricks, 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 is 610mm * 610mm, according to Blockboard 1.22 m * 2.44 m given. Otherwise it will waste a lot of the board. Channel and angle welding must be 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 groove angle plug sockets method is best to use steel works, flat, vertical-sided welding, rust is also very important, just the structure of the package on the inside to absorb moisture easily, San Chao difficult (especially the attic above the bathroom). Best to make a change before making steel rust rust treatment after a good brush, must take the doors and windows open to keep the ventilation, the toxin paints exhausted between light steel inner walls and floor joists filled with glass wool, effective preventing the spread of the audio portion through the air, and for the impact of sound propagation through the solid steel plant drawings, constructed as follows deal: For household wall with two channel walls with wall studs constitute Erdao intermediate space; and for ceiling gypsum board with a small fixed keel, with an elastic structure with a small notch in order to effectively reduce the spread of solid sound between floors. Steel is the main structural steel production, is one of the main building structure types. Features steel is a high strength, light weight, stiffness of steel, so for the construction of large-span and ultra-high, super-heavy buildings particularly suitable; homogeneous and isotropic material is good, is ideal elastomers, best match The basic assumption in general engineering mechanics; material ductility, toughness, and can have a large deformation, can well withstand dynamic loads; construction period is short; its high degree of industrialization, can be high degree of mechanization of specialized production.
