Our engineering core lies in eliminating sagging risks through "Structural Redundancy." First, we accurately estimate the door leaf weight. Second, we determine the number of heavy-duty hinges and the thickness/structure of the frame accordingly. We ensure the combined load-bearing capacity of the frame and hinges significantly exceeds the door's weight,...

Not at all. First, we clearly define size standards during the initial proposal phase. Most importantly, for such projects, we perform factory pre-assembly, integrating and testing the door leaf and frame as a whole before shipping to minimize onsite difficulty. If the site opening has changed (e.g., become larger), a simple adjustment to the opening wil...

For complex projects, we utilize a "Multidimensional Collaborative Mechanism" instead of relying solely on sales. Once a project’s challenges are identified, our technical, design, and installation experts form a dedicated support team. If necessary, we engage in deep alignment with your architects to refine solutions through detailed drawings, prototype...
