The difference between a dark keel ceiling and a bright keel ceiling

1.The dark keel is generally used in large-scale public decoration projects, while the general home decoration project mostly uses the bright keel.

2.The biggest difference between the dark keel and the bright keel is that the keel specifications and keel material, as well as the decoration construction procedures of the surface layer, the minimum specification of the main keel required by the dark keel is 50 light steel material, the secondary keel according to the actual use of specifications, the suspension bar requirements shall not be less than 40cm fire rating for class A, the construction device of the water and electricity line is required to be carried out, and the ventilation port must be reserved, the reason why the dark keel is "dark" is because its base and surface layer decoration design grade requirements are higher, after the keel is installed, Carry out the base decoration, fix the gypsum board on the paper surface, reserve the light trough, and then carry out the treatment of the surface decoration effect, these construction practices cover the keel, so it is called the dark keel.

3.The design requirements of the keel are low-grade, generally directly the base and the surface layer and one, the keel specification is 2mm light steel or solid wood material, the suspension bar is arbitrary, and the fireproof and thermal insulation performance is not so high.

The main difference between the dark keel and the bright keel is that there will be a clear veneer pressure strip between each veneer panel in the ceiling of general home decoration, and the stubble of each veneer can be identified at a glance, which is the so-called bright; The dark is equivalent to adding a seamless layer of the whole room-sized board to this veneer, giving people the feeling of being a structural layer, and it is difficult to distinguish whether it is a ceiling or a ceiling, which is dark.

Hello! The dark keel ceiling is generally used for hotels and families, where the keel is hidden, the surface is sealed with decorative plates, and then further processed to do various shapes. It can be painted in a variety of colors. There is a lot of follow-up work on the dark keel ceiling. But the effect is obvious. Strong installation.

Ming keel ceilings are generally used as integrated ceilings, which are commonly found in shopping malls and large public places. It is generally visible in the form of a grid, with clear lines of the keel and a fireproof board in the middle space. It is suitable for large areas and can also be used in the bathroom.

The construction is simple and there is no follow-up work.

The light steel keel gypsum board ceiling can not be seen after installation, so it belongs to the dark keel ceiling.

The light steel keel has a ceiling keel and a partition keel according to the use, and there are V-type, C-type, T-type, L-type and U-shaped keels according to the cross-sectional form.

The marking order of the light steel keel is: product name, code, width of the cross-sectional shape, height, thickness of the steel plate and standard number. If the cross-sectional shape is "C" type, the width is 50mm, the height is 15mm, and the thickness of the steel plate is marked with the ceiling keel

Light steel keel for construction DC50 15 GB11981.

Appearance quality: The shape of the light steel keel should be flat, the edges and corners should be clear, and the incision should not allow burrs and deformation that affect the use. The galvanized layer is not allowed to have defects such as peeling, tumoring, and falling off.
