We have long experience of producing special metal ceilings on a project-by-project basis. With capability of developing T-Grid automatic machine, we began supplying the various systems of suspended ceiling grids with high quality and precise specification from 1998. Wide range of T-Bar system from economy type to specified function grids meets the requirement from various markets. The test report of loading weight, tension and compression are made according to ASTM standards and certified by SGS Laboratory. At the early of 2005, we began perforated processing jobs for gypsum wallboards, calcium silicate boards and fiber cement boards. Various patterns and holes arrangement are available such as lines, blocks (or grids) and diagonals patterns design.
