What is the size of light steel keel
1. In the current decoration market, there are four main types of light steel keel wall materials, namely 50 models, 75 models, 100 models, and 150 models. And the thickness of the keel is basically 0.4 ~ 2.0mm, which mainly depends on the needs of your choice.
2. When galvanizing keel, it is either hot-dip galvanizing or cold-dip galvanizing, in which cold-dip galvanizing requires a lower price than hot-dip galvanizing. The components of the keel include the main keel, auxiliary keel, and other accessories. There are three main series: D38, D50, D60.
3. The components of the wall keel include horizontal and vertical keels, horizontal support keels, and other accessories. There are four main series: Q50 (C50), Q75 (C75), Q100 (C100) and Q150 (C150).
4. When distinguishing light steel keels, they are distinguished by their width, which determines the type of keel.

Generally light steel keel of good quality, on the surface of the galvanized layer, you can see a relatively clear snowflake pattern, but also has the advantages of hard feel and small gaps.
5. Judging by corrosion resistance
The raw material of the light steel keel is preferably continuous hot-dip galvanized sheet, and the galvanized layer should be very strong, and the galvanized content on each side must also be sufficient, so as to have better corrosion resistance.
Editor's conclusion: After reading the size of the light steel keel and how to judge the high-quality light steel keel, do you have a clearer understanding? We must be particularly careful when choosing the light steel keel, a very small Details can cause huge mistakes.
