1. Integration of design and function
In the high-rise steel structure, the structure has become an important factor in the composition of the image, the shape of the structure, components, nodes to a large extent restrict the image of the building, the design and function of the building and the structure can only be integrated, in order to make the building more functional so that the subsequent design links go on to create a high-rise steel structure building that integrates technology and art
2. Can meet the requirements of degree and super span
The internal organization of steel is uniform, close to isotropic uniform body, high strength, good plastic toughness, and the ratio of density and strength is much smaller than that of masonry, concrete, wood, etc., under the same stress, the steel structure has a small weight, so that it can be made into a large span and a high height building structure, and at the same time, the structure can be flexibly arranged
3. Fast construction speed
The components of the steel structure are prefabricated in the factory and installed on the site. The connection methods widely used in installation are bolt welding connection and bolt connection, etc., which greatly speeds up the construction speed and shortens the construction period. At the same time, the material processing and installation of steel structure buildings are integrated, which greatly reduces the construction cost
4. Green energy saving and environmental protection
Selected with other structures often produce a large amount of construction waste, and the use of steel structure steel can be recycled, construction materials can be effectively used, greatly reducing the generation of construction waste. With the enhancement of people's awareness of energy conservation and environmental protection, people pay more attention to green construction and green buildings, and steel structure just conforms to this trend, which is conducive to energy conservation and environmental protection
Steel girder assembling is used for larger span truss, light steel structure, section 1, H, mouth type mostly, the connection method has three forms of high-strength bolts, bolt welding combination and welding.Portal steel frame, variable cross-section inclined beam or multi-section, solid web welded I-beam cross-section or light H-section, portal steel frame inclined beam is divided into several units according to the transportation conditions, and the units can be connected with high-strength bolts through the end plates.
For the sake of structural stability, easy calibration and accurate installation, for multi-storey structural floors, the top beams should be fixed first, then the lower beams, and finally the intermediate beams.When the installation of columns and beams in a frame is completed, measure and correct this in time.
Steel structure anti-corrosion materials include primer, intermediate paint, top coat, thinner and curing agent.Commonly used are polyvinyl chloride, chlorinated rubber, epoxy resin, polyurethane, epoxy zinc-rich, etc.; commonly used colors are red Dan, medium gray, etc..
Fireproof coating
Process flow: operation preparation → fireproof coating dosing, mixing → spraying → inspection and acceptance of fireproof coating dosing, mixing: powder coating should be used with the allocation.Spraying: The order of applying the coating is generally first up and then down, first difficult and then easy, first left and then right, in order to keep the thickness of the coating uniform and consistent, no leakage of slurry, no falling shall prevail.
Wall panel installation
Acceptance of installation of color plates and flood panels on the wall of light steel structure of steel structure plant.

Roof drainage
Organized drainage is generally the rain roof drainage is divided into organized drainage and unorganized drainage (free drainage), Ben Chau clear thick island brother boundary rainwater drain down, the ditch that collects the rainwater is known as the gutter, gutter refers to the roof of the building
The other is the eaves of the horizontal groove below the gutter that eaves gutter, used to receive the roof of the rain, and then by the general can not calculate the floor area, can be based on when led to the ground.Eaves gutter is divided into outer eaves gutter and inner eaves gutter, the
Vegetable dew offerings, precipitation intensity and drainage speed to determine the size of the gutter ten small
In order to let the rainwater can be very fast very smooth flow to the ground drain, generally take the middle of the high two sides of the low row on both sides of the house to leave a downpipe holes, so that it can be connected directly through the pipeline at the same time after the flower
Installation of gutter picks
Gutters are first fastened to purlins, and after completing the roof panel installation, the picks are used to fasten the outside of the gutters to the roof panel, and the self-tapping nails (pull rivets) are sealed with structural adhesive.Stainless steel gutter is fixed with 2.0 galvanized iron sheet folded U-channel; color steel gutter is fixed with 2.0 galvanized iron sheet folded pieces.
Installation and fixing of rainwater hopper
The connection of the rainwater hopper should be fixed to the load-bearing structure of the roof.The connection between the edge of the rainwater hopper and the roof should be tight and leak-free.The diameter of the connection shall not be less than 100mm when the design does not require it.

Warehouse
A completed steel structure warehouse is a structure made of steel components that has been fully constructed and is ready for use. These warehouses are typically used for a variety of industrial and commercial purposes including storage, manufacturing, retail, and more. They are often constructed from pre-manufactured steel components that are bolted together on-site, but can also be customized to suit specific needs. Steel structure warehouses are strong, durable, and cost-effective, making them an ideal choice for many businesses.
Workshop
Prefab steel Structure workshop buildings are used for industrial production in which all steel structures are painted and then delivered to the project site for installation. And because the steel structure can be manufactured in the factory and installed on-site, the construction time is significantly reduced. Due to the steel it can dramatically reduce construction waste and is more environmentally friendly. Therefore, it widely used in industrial buildings and civil buildings.
Garage
Steel garage doors are made of heavy-duty, real-gauge steel, which is hot-dip galvanized in zinc to protect against rust. Steel garage doors can have multiple layers that each add strength. The layers often include insulation, cladding, steel and a composite overlay. The composite overlay will determine the look of your door.
