What is LOFT Mezzanine Floor?
Huachengxing LOFT Mezzanine Floor, also referred to as LOFT Steel-Frame Floor, is a high-density compressed fiber board integrated within a steel support structure. It is commonly used as an intermediate floor system in duplex or loft-style buildings with high ceilings (typically 4.8 to 5.6 meters).

Thanks to its lightweight nature, high strength, and slim profile, this floor system helps create a sense of spaciousness, visual continuity, and an open, flowing layout. The result is a brighter, more expansive interior with an enhanced aesthetic and modern artistic appeal.

I. Production Process
Huachengxing LOFT Mezzanine Floor is made primarily from Portland cement, natural minerals, fibers, and paper pulp as key raw materials. The manufacturing process involves pulping, molding, high-pressure compression, and high-temperature steam curing.
