Import Composite Door — Buy in Bulk from Supplier in China

The composite door offered by Zhejiang Junwei Doors Industry Co., Ltd is a prefabricated entry solution that combines a steel core with a protective plastic coating. It is constructed from a surface‑spray plastics cold‑rolled steel plate, which gives the panel resistance to wear and impact. Dimensions are fully customisable to match a broad selection of opening sizes, and the design incorporates multiple locking mechanisms for enhanced security. The door also features high thermal‑insulation properties that help reduce heat loss in both residential and commercial buildings.

In the door industry, composite panels typically use a steel substrate of 0.8 mm thickness with a 0.5 mm plastic veneer, delivering a total panel thickness around 45 mm, which is regarded as standard for medium‑security doors. Standard fire‑rating for such doors is Euroclass B‑s2,d0, and a typical U‑value of 1.2 W/m²·K provides good energy performance. The finish can be powder‑coated in a wide colour range, and a typical warranty period of five years is offered by many manufacturers.

The doors are suitable for new‑build homes, office blocks and retail premises, where a balance of aesthetics and security is required. Zhejiang Junwei supplies the product with ISO and CE certifications and offers FOB or CIF shipping terms, while the minimum order quantity is not disclosed and should be confirmed directly. Packaging is designed to protect the panels during transit, using reinforced wooden crates or palletised frames.
