Many people are relatively unfamiliar with the keel, but friends who have done the decoration know that the keel is a kind of building material that supports the shape and the fixed structure. Widely used in hotels, terminal buildings. Passenger stations, railway stations, theaters, shopping malls, factories, office buildings, renovation of old buildings, interior decoration installations, ceilings and other places. The following Xiaobian introduces the quality of the keel and the type of keel.
What is the keel
The keel is the skeleton and base material of the decoration, and is only used as a building material supporting the modeling and fixing structure. According to the material, construction process, decorative parts of the difference. According to the material, it can be divided into wood keel, light steel keel, aluminum alloy keel, steel keel and so on. According to different construction techniques, there are load-bearing and non-load-bearing keels (ie keel on the person and not on the keel). According to the use of the site to be divided, can be divided into ceiling keel, vertical wall keel, paving keel (wall keel) and hanging keel.
Keel quality discrimination
1. Anti-rust on the surface: The project includes testing indicators such as double-sided galvanizing amount, double-sided galvanized layer thickness and coating pencil hardness. The double-sided galvanizing amount is an important indicator in the surface rust prevention inspection project. The national standard stipulates that the double-sided galvanizing quantity index of the ceiling keel qualified product ≥ 100g/m2. The double-sided galvanized amount of the light steel keel is unqualified, which will greatly reduce the anti-corrosion and anti-rust capabilities of the product, resulting in shortened product life.
2. Cross-section size: The project includes inspection indexes such as thickness, width, height, hemming width and hemming height of light steel keel.
3. Mechanical properties: The project includes the load-bearing (main) keel static load test of the light steel keel and the surface (sub-) keel static load test, and the wall static load test and wall impact test of the light-gauge steel keel. index. Static load test is an important indicator in the test of mechanical properties.
Types of keel
According to the use of the site to be divided, can be divided into ceiling keel, vertical wall keel, paving keel and hanging keel.
According to different construction techniques, there are load-bearing and non-load-bearing keels (ie, the keel on the person and not on the keel).
According to its different models, specifications and uses, there are T-line, C-shaped, U-shaped keel and so on.

Light steel keel is a very popular decorating material for several years. It can be used for ceilings, partition walls, and has strong fireproof performance. Light steel keels can make various beautiful shapes.
The ceiling metal keel is usually made of light steel and aluminum alloy. It has the characteristics of light weight, high rigidity, good fireproof and anti-seismic performance, and easy processing and installation. According to the profile section, there are U-type keel and T-type keel. Such as dragon card wall keel with light weight, high strength, good corrosion resistance, etc., can be used as a lightweight partition wall material, mainly with the use of gypsum plasterboard and its products, can also be used with other boards such as: GRC board , FT board, Aetna board and other materials supporting the use of.
Editing summary: The quality identification of the keel and the type of keel are introduced here, and I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
