Gypsum board ceiling side keel with a good side of the wood or supporting the light keel edge keel good?
Work with wood keel is good, the quality is still supporting the light steel keel is good, at least not easy to deformation, not raw insects (fixed time when a few points)
The edge of the wood keel good
Of course, is the use of supporting the light steel keel (edge keel) better, and the construction (operation) will be more convenient.
