Light steel keels are commonly used in metal ceilings and construct structures, and manufactured by Different Shape False Ceiling Channel Roll Forming Machine. But there are many different specifications of light steel keels on the market today.
The next step is to introduce you to several specifications of light steel keel.
Light steel keel specifications are mainly 50mm, 75mm, 100mm and other specifications.In general, when carrying out paper-faced gypsum ceiling, light steel keel is needed, while thin gypsum board is used for thin keel.
For higher heights, you can choose the national standard specifications so that the light steel keel will have a stronger load-bearing capacity.
How to judge the quality of light steel keel?
Judging by the shape of the section
Light steel keel section can be divided into 4 models, U,C-type keel is called heavy keel, can be used for partition keel, while t, L-type keel will be slight less load-bearing, not used for ceiling above.
Judging according to the thickness of the keel
In judging whether it is quality light steel keel, you can look at the thickness of the keel, generally good quality light steel keel thickness in 0.6mm or more, and then through observation and touch, to determine the thickness of the broken aluminum buckle plate.
Judging by the galvanizing process
In order to prevent the light steel keel from rusting, the surface needs to be galvanized, so you can judge the light steel keel by the galvanizing process, if the galvanization does not fall off, pockmark, etc., it means that the galvanization layer of the light steel keel is better and can play a very good role in preventing moisture.
Judging by corrosion resistance
For high quality light steel keel, the raw material of light steel keel is made of hot plated plate as far as possible, which will be more solid, and the galvanized content of each side should be sufficient, so that the corrosion resistance of light steel keel is better.
We hope you find the above helpful.
