Steel Building Specification
Steel Building Specification provide the basic information about the Prefab Steel Building, which include Warehouse, Workshop, Shed, and Garage Building.
Steel building is a structure composed of steel materials, which comprised of steel columns, steel beams, steel trusses, and other components. The parts usually connected by welding or bolts. Because of its lightweight and comfortable construction, it widely used in Workshop, Warehouse, Stadiums, and High-rise buildings.
Steel Building Specification- Portal Frame
The portal steel frame is a traditional structural system. The mainframe includes Steel Column and Roof Beam, and the secondary structure includes Bracing, Strut, Purlins, and tie rods.
The Structural of Portal frame divided into Single Slopes, Double Slope, Multi-span with multi-gable roof, Multi-span with double-gable roof, and Muli-span with the single slope.
Steel Building Specification - Type of Portal Frame
The portal frame structure is mainly composed of steel columns and roof beams, and the frame is a plane loading system. To ensure longitudinal stability, which column bracing and roof bracing will arrange.
The portal frame divided into several forms,
1. Typical portal steel frame.
2. Steel frame with the crane.
3. Steel frame with mezzanine structure.

Bracing Structure
The portal frame，purlin，Bracing system and the metal cladding rely on each other through reliable connection and support.
The main structure of the portal frame load-bearing structure divided into two types according to the kind of the rigid frame: the clear span structure without interior columns and the multi-span continuous structure with interior columns.

According to the specific project, it can also be used in single and multiple slopes, as well as in different spans and heights. Most of the foundation types adopt reinforced concrete independent foundations. According to the diverse requirements of the building for lateral displacement and deformation, from the perspective of saving steel, a variable-section beam-column, foundation hinge structure scheme, or an equal-section column variable-section beam, foundation rigid structure scheme can be adopted.
Bracing System
The main functions of the bracing system are:
1) The strut beam transmits the longitudinal horizontal force.
2) The horizontal bracing resists the horizontal force transmitted between the columns and roof beams.
3)Flange Bracing use to keep the stability of the outer plane
4) All bracing systems, together with purlin or wall girt and portal frames, which form a space system, which ensures the overall function of the space of the structure, bear, and transfers horizontal loads, and ensure the stability and convenience during the installation.

Purlin and Wall Girt
The main component types of purlins and wall girt are C-type or Z-type steel, and the size of the cross-section needs to determine through the load calculation. Compared with the Z-section, the mechanical properties of the C-section are quite different, C section steel connects to the portal frame bolted.
The Z-section can rigidly connect by substantial overlap, which can calculate as a continuous beam.
Therefore, in addition to door and window openings and other specialized areas, Z-sections should be preferred. The distance between the purlin and the wall girt usually not exceed 1.5 meters.
Application Range
The application of the portal frame light steel building, which includes single-story industrial buildings, includes Warehouse, Workshop, and Storage Building, Commercial Building includes Supermarkets and Exhibition halls, and Agricultural Building includes Metal Barn, Poultry, and livestock building.
Multi-stories Steel Frame
The multi-stories steel frame is composed of steel beams and columns and can withstand vertical and horizontal loads. The frame structure should meet not only the requirements of strength and stability but also ensure the overall strength of the frame.
The steel frame has ample internal space and flexible layout, which can meet the needs of different buildings, and the construction speed is fast. The steel frame structure mainly made of steel, which is one of the main types of building structures.
