What is a bright keel and a dark keel ceiling, and what is the difference between the two?

When it comes to light steel keel ceilings and wood keel ceilings, everyone is familiar with them, and they know a little bit about them. But when it comes to the bright keel ceiling and the dark keel ceiling, you may be a little confused and don't know what it is. Today, the editor will explain to you what is a bright keel ceiling and a dark keel ceiling, and what are the differences between the two, you can come and learn!

What is Ming Keel Ceiling?

The board used is directly placed on the keel, so the keel is exposed, and part of the keel can be seen, so it is called a Ming keel ceiling.

What is a dark keel ceiling?

Generally refers to wood keel, light steel keel and embedded ceiling keel, used for the overall surface process such as gypsum board, wood plywood + veneer and aluminum square plate.

The difference between the two:

1. Purpose

Dark keels are generally used in large-scale public installation projects, while open keels are mostly used in general home improvement projects.

2. Specifications and materials

The big difference between the open keel and the dark keel lies in the keel specification and keel material, as well as the decoration construction procedure of the surface layer. It is required that the fire rating should not be lower than 40cm, and the fire rating should be Class A. It is required that people can access the construction equipment of water and electricity lines, and vents must be reserved.

3. Design and construction

The reason why the dark keel is "dark" is that its basic and surface decoration design requirements are relatively high. After the dragon skeleton is installed, the basic decoration is carried out, the paper surface gypsum board is fixed, the light trough is reserved, and then the surface decoration is carried out. The processing of the effect, these construction practices cover the keel, so it is called the dark keel.

The design requirements of Ming keel are of lower grade. Generally, the base layer and the surface layer are directly combined into one. The keel specification is 2mm of light steel or solid wood material. The hanging bars are optional, and the fireproof, thermal insulation and thermal insulation performance is not required to be so high.
