Angola Prefab Steel Structure Warehouse Shed


Economic Prefabricated Warehouse

The project consists of four buildings. The main two-story building is fully controlled by air-conditioning and air-conditioning, and the Prefabricated Warehouse is equipped with internal and driving devices. Driven buildings use floor radiant heating for heating. The windows on the mezzanine on the east side provide a 24-hour view of the rolled doors inside.

The steel structure warehouse is a new type of building structure system, which is composed of the main steel structure connecting the H section, Z section and U section steel components, roof and walls, using various sandwich panels or corrugated steel color panels, doors and windows and other components. It can be single span, multiple spans, and multiple scenarios with different uses. Steel structure warehouses are widely used in warehousing, logistics centers, distribution centers, etc. As a new type of steel structure building system, steel structure warehouse has the following advantages:

1. Environmentally friendly and energy exchange;
2. The structure is fast and easy to install;
3. The wide span can be 60 meters without intermediate column;
4. Long life span up to 50 years;
5. The magnitude of the stability and earthquake is as high as 9 points.
