1. Product Description:
The general H-beam-based, the main structure of the unit as a unit, the unit by the column and beam combination for the door, there are no columns or even span, with the support between the mast and purlin connection.

2. Features:
● With light roof, not only can reduce the beam column cross-sectional size, the foundation is also reduced accordingly.
● Large double-slope roof that can be made into a ridge in multi-span buildings, which creates the conditions for long slope drainage. Set the middle column can reduce the span of the beam, thus reducing the cost. The middle column made of steel pipe up and down hinged swing column, small space.
● Lateral stiffness The purlins support ensures that the longitudinal rigid members are eliminated and the flange width is reduced.
● Rigid frame can adopt variable section, the section is proportional to the bending moment; when the section is changed, the height and thickness of the web and the width of the flange can be changed according to the need, so that it can be fully used.
● The webs of the frame can be designed with an effective width that allows part of the web to be destabilized and makes use of its buckling strength. Therefore, the ratio of web thicker than "Steel Design Code" (GB50017) provides for the large, you can reduce the web thickness.
● Vertical loads are usually designed control loads, but the role of wind loads should not be ignored when wind loads are high or buildings are high. In light-roofed gantry, the seismic action can not generally be controlled.
● support can be done lighter. The direct or horizontal gusset plate connected to the web, the tension bar can be used.
● All structural components can be made in the factory with high degree of industrialization. Component units can be divided according to transport conditions, the units are bolted in the field, quick and easy installation, civil construction less.

3. Use:
Widely used in industrial plants, airport garages, stadiums, warehouses, shopping centers and other industrial and civil buildings.
