The double-wing expansion room is also called the double-wing folding room. It uses galvanized high-strength square tubes, galvanized angle irons and other light steel materials as frames, anti-corrosion double-sided color steel composite panels as walls, and high-strength hinges are used to link the frames. After scientific calculation, it can quickly expand the space of the house. The space of the house after expansion is nearly 3 times larger than before expansion. 20-foot and 40-foot expansion rooms can be made, and they can also be customized according to customer needs. It is a kind of house with high technical content among the container houses for living.
The double-wing expansion room uses hinges to link the walls before compression, and the volume after compression is greatly reduced, which is convenient for transportation. It can be transported by truck or loaded in shipping containers for export.
The main reason why the exported expandable houses are favored by foreign customers is that there are relatively few double-wing expansion room manufacturers and double-wing folding room manufacturers abroad, and the cost of building houses is high. Purchasing from China, including product prices, shipping costs, and customs clearance costs, is also lower than their production costs.
The double-wing expansion room integrates water and electricity systems, toilets, showers, kitchens, etc., which can be installed before leaving the factory according to customer needs. In order to meet export requirements, all internal materials have been inspected by foreign testing departments. In terms of workmanship, the quality of the exported houses is very good. After all, the product quality is good, and the customer return rate is still quite high.



The double-wing extension house has many advantages
1: Easy to install. After being transported to the destination, it only takes 1 hour to assemble the house.
2: Convenient transportation. One 20-foot shipping container can be loaded. A 40-foot shipping container can be loaded with 2, which greatly improves the convenience of transportation.
3: Long service life. The service life of the double-wing extension house can reach 10 years. Because the frame uses galvanized anti-corrosion house pipes, the wall panels use galvanized thickened wall panels, and the hardware is also stainless steel anti-corrosion, so the corrosion resistance is better. At the same time, the weight of the house reaches 3 tons, which has good wind resistance. Even in harsh natural environments, the probability of damage to the house is relatively small.
