Brief analysis on the quality of keel and identify

  • Detail

Keel is a very popular decoration material in recent years. It can be used for ceiling, partition wall and strong fire prevention function. It can make all kinds of beautiful shapes with light steel keel. The ceiling keel is usually made of light steel and aluminum alloy, which has the characteristics of light self weight, high rigidity, good fire and earthquake resistance function, convenient processing device and so on. According to the profile section, there are U-shaped keel and T-shaped keel

many people are still unfamiliar with the keel, but friends who have done decoration know that the keel is a kind of building material used to support the shape and fix the structure. It is widely used in hotels and terminal buildings. Passenger stations, stations, theatres, shopping malls, factories, office buildings, reconstruction of old buildings, indoor decoration settings, ceilings and other places. The following editor will introduce the quality identification and types of keels

what is a keel

a keel is the skeleton and base material of decoration. It is only used as a building material to support the shape and fix the structure. It can be divided according to different materials, construction processes and decorative parts. According to materials, it can be divided into wood keel, light steel keel, aluminum alloy keel, steel keel, etc. According to different construction processes, there are load-bearing and non load-bearing keels (i.e. accessible keels and non accessible keels), etc. According to the use position, it can be divided into ceiling keel, vertical wall keel, floor keel (partition keel) and hanging keel

quality discrimination of keel

1. Surface rust prevention: this item includes detection indicators such as double-sided galvanized amount, double-sided galvanized layer thickness and coating pencil hardness. The amount of double-sided galvanization is an important index in the surface rust prevention inspection items. The national standard stipulates the amount of double-sided galvanization index of qualified ceiling keel ≥ 100g/m2。 Unqualified double-sided galvanization of light steel keel will greatly reduce the corrosion resistance and rust prevention ability of the product, thus shortening the service life of the product

2. Section size: this item includes the thickness, width, height, crimping width and crimping height of light steel keel

3. Mechanical properties: the project includes the static load test of bearing (main) keel and cladding (secondary) keel of light steel keel, as well as the wall static load test and impact resistance test of wall light steel keel. Static load test is an important index of mechanical property inspection items

types of keel

according to the use position, it can be divided into ceiling keel, vertical wall keel, floor keel and hanging keel

according to different decoration construction processes, there are load-bearing and non load-bearing keels (i.e. accessible keels and non accessible keels), etc

according to the different models, specifications and uses, there are T-shaped, C-shaped, U-shaped keels, etc

wooden keel is a commonly used material in decoration. It has many models and is used to support the external decorative board and act as a support

light steel keel is a very popular decoration material in recent years. It can be used for ceiling and partition walls. It has strong fire resistance. It can make all kinds of beautiful shapes with light steel keel

the ceiling metal keel is generally made of light steel and aluminum alloy, which has the characteristics of light self weight, high stiffness, good fire and seismic performance, convenient processing and installation, etc. according to the profile section, there are U-shaped keel and T-shaped keel. Rulong partition keel has the advantages of light weight, high strength, good corrosion resistance and so on. It can be used as the skeleton material of light partition wall. It is mainly used with paper gypsum board and its products, and can also be used with other plates such as GRC board, FT board, Aite board and other materials

editor's summary: that's all for the quality discrimination and types of keels. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
