Steel structures attic should find the best professional before making a few points to note about the loft attic loft designed steel structure design. In order to determine the level of construction steel works 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. Construction to determine the level a little, 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 method is best to use plug sockets, 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). Before making the best rust treatment to make a change after the steel rust brushed steel production, must take the doors and windows open to keep the ventilation, the toxin paints exhausted steel building design: 1, using professional design software (PKPM, 3D3S, PS2000, MTS, Xsteel, Tengen, MSTCAD, SFCAD, CAD, etc.) steel metal housing design, conduct program design, optimization design, detailing and deepen the design, construction design, construction secondary design! 2, to undertake industrial, residential and commercial building design and analysis of structures. Including industrial plants, warehouses, supermarkets, exhibition halls, greenhouses, light steel ceiling and roof, activity room, plus steel layer (sandwich) transformation, the transformation of reinforcement technology, canopy, grid, space truss, etc; civil buildings, villas, airports, railway stations, 4S car shop; steel structure, frame structure, a multi-layer steel structures, steel platforms, steel stairs, equipment rack, elevator shafts steel frame, non-standard structural engineering design, decorative frame design, billboard frame design, curtain wall design, sun room design. 3, the studio has excellent steel steel design team, from the well-known large-scale professional design institutes and steel company, has many years of rich experience in design and construction of steel structures, can be more perfect and efficient completion of each set of drawings , the ability to detect and resolve errors of omission blueprint design to reduce the cost of the entire project, to ensure that every project our customers 100% satisfaction. 4, professional grade steel design, a map and seal.
