The ceiling keel is an important part of the ceiling, and they isomorphically construct the three-dimensional structure of the ceiling. This paper will introduce the difference between bright keel and dark keel to help readers better understand the ceiling keel.

Open keel: T-shaped keel

The open keel is the visible part between ceiling panels, and its cross section is inverted T-shaped, which provides support for the panels from top to bottom. There is a big gap between the decorative plates with keel, which is suitable for office area and convenient for future maintenance.

Hidden keel: triangular keel

Dark keel is the invisible part between ceiling panels, and its cross section is inverted triangle, which provides support for panels from bottom to top. The gap between the decorative plates of the hidden keel is smaller, and the sealing performance is better, so it is suitable for places that need moisture protection, such as toilets.
