There is no decorative layer or a simple painted decoration on the exterior of the curing barn. The other is the light steel keel structure: the light steel keel serves as the structural load-bearing component, and the wall and roof are made of polyurethane color steel sandwich panels, which serve as enclosures and provide heat insulation functions, without a decorative layer. Neither of the above two structures belongs to the integrated structure, heat preservation, and decoration type, and the on-site construction is cumbersome, and a fully prefabricated construction method is not adopted.
