A steel structure building is a metal structure fabricated with steel for internal support and for exterior cladding, as opposed to steel framed buildings which generally use other materials for floors, walls, and external envelopes. Steel buildings are used for a variety of purposes including workshops, storage, workspaces, warehouse, aircraft hangar, and riding arena. They are classified into specific types depending on how they are used. The base material of steel structure building is good quality Q235/Q345 steel. Earthquake conditions is 8 Degree earthquake conditions,Climate conditions -20°C-45°C,Snow load100 Kg/m⊃2;,Wind speed150 Km/h.

The steel structure building is composed of several different functional systems, mainly including: structure system（including main structure, roof and purlin system, wall and beam system）,maintenance system ( including roof panel, wall panel, covering and floor deck), door and window system(including door and window), ventilating system (including clerestory system and ventilators), drainage system (including gutter, rain-spout and awning), Truss, Cranes etc.
Steel structure buildings are generally framed structures and range from simple one-story buildings to multistory structures. There are three common types of steel buildings. All three types of buildings have one advantage in common - they are built with steel. Steel is so durable yet lightweight in the world.
Arch buildings have a self-supporting structure with no interior columns, beams or trusses. The exterior sheeting acts as the interior and exterior wall, ceiling and roof.
Arch-type buildings are limited in size. You can create as much length as you need by adding arched sections to the ends of the building. The interiors have clear open spaces, but the height is limited to the bottom of the roof curve or eave height. Peaked roof styles provide a bit more height in the center.
There are some disadvantages.
A single span rigid frame is constructed with one beam supported at either end. It is also known as a continuous frame. Rigid frame buildings are constructed with steel I-beams assembled into trusses.
Steel purlins are placed perpendicularly to the I-beams from floor to ceiling ever three to six feet. Insulation is placed and the interior finished.
The primary benefit of single span construction is unobstructed covered space without interior columns. The width can be expanded feet using tapered or straight columns without worrying about limited headroom at exterior walls.
A single span rigid frame is most often used for churches, office buildings, aircraft hangars and sports arenas; structures that require uninterrupted space and versatility of interior design.
The disadvantage of single span design is the structure often appears box-like and has minimal roof-pitch. The commercial appearance may require special zoning permits and it is not a do-it-yourself project. Single span construction often calls for cranes and other equipment.
Multi-span construction increases the potential size of the building nearly unlimited because it uses interior support columns for added strength. The columns can be placed wherever they are needed and are usually hidden within the walls. Rafters and beams can be tapered or straight, providing design flexibility.
A multi-span rigid frame is ideal when you require an expanded interior space and the presence of columns is not an issue. You can create immense space with endless design possibilities. Warehouses and factories are often built using multi-span rigid frames.
There are three different methods for the design of steel structures building i.e. simple design, continuous design, and semi-continuous steel design. We have a professional and normalized design team, through AutoCAD, PKPM, Tekla Structures (Xsteel), 3DS MAX and etc,we provide full designging and detailing service to all customers. we can design complex metal buildings like office buildings, shopping malls, apartments, retail shops, workshops, warehouses, sheep shed, riding arena, and so on. The professional working team has been the basement for us to devote ourselves to build a world brand "YILI Steel Structure".
A steel structure building must be designed and constructed so as to safely resist the applied load. The applied load consists of dead loads, live loads, and environmental loads. The dead load includes the self-weight of the steel structure and permanent fittings and equipment. Live load includes the weight of the steel structure's occupants and contents. Environmental loads include the effects of snow, wind, earthquake, rain, and flood. Additional loads may also be imposed by the self-straining forces caused by temperature changes, shrinkage, or settlement.
The design of a structural steel building must take into consideration the different combinations of loads that may be applied to the steel structure and also the variable nature of each load. To allow for this, load factors are applied to the nominal loads and several different combinations are checked. In each combination, one variable load is taken at its maximum lifetime value and the other variable loads assume arbitrary point-in-time values.
The deflection of members must be limited to ensure that damage does not occur in supported elements. This is particularly important in the case of beams supporting plastered ceilings and sensitive partitions and cladding. Vibrations must also be controlled.

Here's why multi-floor steel buildings are an affordable and convenient solution for your construction needs
Steel structure relative to the concrete structure, its shortage is bearing relatively poor, so the steel structure for wall materials requires more lightweight, obviously, the traditional block is very difficult to meet this requirement, lightweight partition board and steel structure building has become a perfect partner. There are three common types of panels used in multi-floor metal buildings. Each one has unique properties, depending on the kind of structure you're building or the kind of environment surrounding it. Here is a brief overview of each type of metal wall panel: single skin, metal composite material, and insulated.
Multi-storey buildings with metal wall panels single skin metal panels are also referred to as preformed or roll-formed panels. Most wall panels of this type can be installed horizontally or vertically in less time and with less of the cost of other metal panel systems. They can come insulated or uninsulated and can be made with protective coatings that help fight corrosion and fading. There are certain benefits to using single skin metal wall panels including:
This type of metal wall panel has been used in steel structure projects in North America for almost 40 years. These panels are formed by joining two thick metal skins to a core that is made of polyethylene or other fire-retardant plastic material and bonded under a specific temperature, pressure, and tension. The end product is a metal/plastic composite with greater benefits than just using a solid metal panel of the same thickness.
As the name suggests, this metal wall panel is made with an insulating foam center (typically expanded polystyrene or polyisocyanurate) sandwiched by two aluminum or steel metal face panels. They make an excellent choice for commercial or industrial buildings and climate-controlled facilities.
When deciding whether or not you should use IMPs for your job, environmental factors should be taken into consideration, as these metal panels need to be sealed properly to prevent water intrusion. Climate also plays a deciding factor, so take into consideration the humidity, temperature, and air movement of the location you plan to install these metal wall panels.
Insulated metal wall panels are great to use in some metal building applications because:
