5. Made of primary aluminum material and treated with Akzonobel powder coating on the surface, it features excellent corrosion resistance and strength, and can adapt to various complex environments.

6. During the opening and locking process of the compact door, it moves 8mm laterally, providing a stronger seal and resolving the contradiction between the sealing performance and the comfort of operation of ordinary sliding doors.

7. It adopts an upper lift and lower press design and a lower rail high and low rail design, which is not only waterproof but also wind-resistant, and has stronger drainage.

8. It is equipped with a full set of imported brand hardware, enhanced locking and upgraded sealing, which can reach the RC2 safety anti-picking level.
