The components such as customized Wave Type galvanized corrugated steel sheet produced in the prefabrication plant shall be transported to the site by means of transportation means. The choice of transportation mode shall be based on the size and weight of the components, the number of components and the distance of transportation, and the specific conditions of the existing transportation vehicles. Determine after comparison. It is generally transported by car and flatbed trailers, and the components are transported directly to the construction site.

During the transportation of the galvanized corrugated steel sheet, the components must be protected from deformation, non-dumping and damage; the transport road should be flat and solid, and the speed should be determined according to the road conditions to maintain a smooth running; the concrete strength of the reinforced concrete members should not be lower than the design strength level. 70%; the loading and unloading of the components should be stable, and the transportation should be fixed firmly to avoid dumping; the position of the component pads should be correct during transportation, and the loading and unloading points should meet the design requirements. Transportation work should be reasonably organized, and should be hoisted first and supplied according to the hoisting order.

After the components enter the site, they should be stacked according to the plan layout plan of the structure hoisting plan prepared in advance to avoid secondary transportation. Generally, large-scale components such as columns and roof trusses should be placed in accordance with the layout plan of the components in the construction organization. The small and medium-sized components are stacked at the specified positions. Generally, the beams can be stacked 2-3 layers and the Galvanized Corrugated Steel Sheet can be 6-8 layers.
