We founded the plant in 1992 to make sealing strips for aluminium windows, doors and curtain walls, and have built a reputation among the sealing strip makers of Haining. Originally Haining Longyuan Rubber & Plastics Factory, we moved to the Haining Economic Development Zone and became Haining Longyuan Sealing Strip Co., Ltd. to support our technical upgrade. Longyuan runs modern extrusion lines and a trained workforce of operators and technicians able to meet the order requirements of different customers. We mainly make custom sealing strips, window and door gaskets (push-in and slide-in types), glazing blocks, anti-collision blocks, insulating glass seals, curtain wall seals, seals for electric-bike doors and windows, and various special sections.
