Specification and quality problems of light steel keel

Partition keel refers to partition light steel keel, which are used as decoration by most families. In the followings, i will introduce some specification and quality problems of light steel keel to you.

Specification of light keel

The thickness of light steel keel is from 0.4 mm to 2 mm. In general, most people choose light steel keels when using paper plaster ceilings. Thin gypsum board using thin light steel keel, gypsum board thicker with a thicker light steel keel. There are two types of galvanized keel, cold galvanized and hot galvanized. Hot galvanized prices are higher.

partition keel

Should pay attention to the quality problem

1.Wall shrinkage deformation and board surface cracks: The reason is that the vertical keel tightly up and down the keel, did not allow expansion and contraction, more than 2 meters long wall does not control the deformation joints, resulting in wall deformation. A 3 mm gap should be left so that distortions and cracks due to temperature and humidity effects can be reduced.

2. Light steel skeleton connection is not strong, because the local node does not meet the construction requirements, the installation of local nodes should be strictly in accordance with the provisions of the map. Pinning spacing, location, connection method should meet the design requirements.

3. Wall coverings are uneven, and most of them are caused by two reasons: one is the lateral misalignment of the keel, and the other is that the thickness of the plasterboard is not uniform.

Metal Decoiler For Roll Forming Machine

All the roll forming machines need raw material to be processed and produce the finished product to sell. So the metal decoiler is a important part for the whole production line. The metal decoiler is  used to support the steel coil and uncoil it in a turntable way. It doesn’t need so much space. And it has many types for you to choose. There are cheap decoiler and fully automatically. Which one you want, we can provide you.

The parameters of metal decoiler for roofing sheet machine, it can be customized according to your requirements.

Passive uncoil pulled by roll forming system.

  1. Loading capacity: 1.5T
  2. Uncoiling width: 300mm
  3. Inner diameter: 450-550mm

There are three types for your reference.

1, Manual decoiler

manual decoiler

2, Hydraulic decoiler

hydraulic metal decoiler

3, Hydraulic decoiler with loading car

The feature of the hydraulic decoiler with car is that have functions compared the manual one.

Such as the press arm, loading hand and loading car.

Obviously, the loading car is the most different part beside the decoiler.

This loading car is controlled by the remote. It can move forward and back up.

Especially, the height of the car can be adjusted. So that the car can put the coil on the decoiler very easily.

The max. coil weight for the car is 10 Tons.

There are so many types for you check. They are easy to operate and our engineers can give you a training if you need. It is our pleasure to give you our professional advice. And we also have various kinds roll forming machine, if you have the requirements, please feel free to contact with us.



Introduction of light steel villa

In modern times, more light steel villa instead of traditional buildings. What cause this solution? Now i will introduce some information to you. Light steel villa compared to the traditional residential, has its outstanding advantages:

(1) light steel villas of light steel structure parts production factory and a high degree of mechanization, high degree of commercialization.

(2) Light steel villa construction site fast, will not affect the nearby residents conducive to civilized construction.

(3) The light steel villas’ steel structure buildings are environmentally friendly and sustainable products.

(4) light steel villa light weight, good seismic performance.

(5) Comprehensive economic indicators of light steel villa is not higher than the reinforced concrete structure.

(6) Compared with brick house, light steel villa can avoid waste of resources

(7) light steel villas because of the light steel structure of the wall thickness is smaller than the brick structure can increase the effective use of the area;

(8) Compared with reinforced concrete residential buildings, light steel villas can be reused after being made of steel with light steel structure, but concrete can not be reused. It will certainly be construction waste afterwards, resulting in environmental stress. Concrete will take 40 years to fully dry , So likely to cause indoor moisture, moisture, is not conducive to human health. However, light steel structure completely without concrete, so there is no such problem.

(9) light steel house seismic performance. Due to the earthquakes activities of left and right and up and down activities, the light steel structure that is screwed together forms a safe and stable box, and does not collapse or collapse of the floor due to the shaking of the earthquake and endanger personal safety.

(10) Light steel villa construction using dry construction method, will not cause waste of water information. And save costs.

Second, light steel villa floor structure

Light steel villa floor by the cold-formed thin-walled steel frame or composite beams, floor OSB structural board, support, connectors and other components. The materials used are oriented strand board, cement fiber board, and plywood. In these light floor can withstand the load of 316 to 365 kg per square meter. Light steel villa floor structure system weight is only one fourth to one sixth of the traditional domestic concrete floor system, but the height of the structure of the floor than the ordinary concrete slab 100 to 120 mm.
