The Pre-Shipment Inspection (PSI) is one of many types of quality control inspections conducted by Lida Group. This inspection is done according to standard QC Test, or based upon customer requirements. Samples are selected and inspected for defects at random, according to these standards and procedures. For us, Pre-Shipment Inspection is an important step in the quality control process and is the method for checking the quality of prefab house manufacturers before they are shipped.

Being exceptional in producing top quality steel structure building, Lida Group has turned into a superstar manufacturer in the market. The glass green house is one of the main products of Lida Group. It is highly resistant to scratches or scrapes. It has passed scratch hardness tests to effectively resist scratching due to the friction or pressure from a sharp object. This product is able to go through heavy rains or hurricanes. It is hard to develop Lida Group without the assurance of quality of prefab houses. This product features a stable structure, which is not easy to collapse.
