Light steel structure

The framework of light steel structure is a lightweight steel frame arrangement of the stem of a manufacturing system with assembly and calculations using the assistance of computer software. Materials used are high quality steel that is thin and lightweight. To prevent the occurrence of corrosion, the material is given galvanize or galvalum layer (layer of aluminum and zinc).
Elements of the roof structure is light steel trestle,row, and in the screw. Distance of light steel trestle, depending on the weight of the roof cover. The weight of the roof covering the distance of meeting its light steel trestle. For example by using the cover concrete tile roof, the distance between the light steel trestle can reach 1.4 m. Material thickness for light steel trestle ranged from 0.75 to 1 mm, while the thickness between 0.4 - 0.7 mm

The advantages of light steel roof structure, including:
a. Its light weight compared with the structure of the wood so that the burden should be borne by the structure under roof more.
b. Anti termite.
c. Fire-resistant.
d. It is not expand and shrink.
e. Installation faster than with wood because it is a structure of a series.

While the lack of light steel roof structure is, among others;
a. Need cover because underneath ceiling light steel structure cannot be in Expose. b. The form of the roof does not flexible like wood that is easily cut and formed.
c. Calculation of the structure must be appropriate and requires the careful supervision at the time of the error because a part of the structure will damage the other.

With the more expensive and difficult to get quality wood then use the framework of light steel roof is to be the right alternative. This is because the cost incurred for the roof structure is almost equivalent to the type of wood, depending on the model of the roof and the roof cover will be used. The more complex model of the roof and the weight of the roof will cover the greater costs.
