As a landmark super-high-rise financial complex in North China’s core city, the Tianjin International Financial Center sets multiple stringent requirements for decorative building materials in terms of fire resistance, weather resistance, deformation resistance, environmental friendliness, and lightweight design. Mogan Mountain has developed an integrated interior design solution for high-rise public buildings featuring a fire-retardant base layer specifically designed for northern regions and ENF antibacterial, paint-free cabinetry. This solution specifically addresses the challenges of North China’s dry climate with significant temperature fluctuations, high-rise enclosed environments, and high occupancy density, while balancing building fire safety, occupant health, and long-term durability. It has become a benchmark case for material selection in Grade A office towers and high-end star-rated hotel complexes within CBDs of northern Chinese cities, consistently demonstrating Mogan Mountain’s capabilities in supplying building materials for major national landmarks and its comprehensive capabilities in supplying building materials for large-scale public construction projects in northern China.
