Light Steel Frame

Construction in Indonesia in this time generally use various concrete material, brick, steel and wood. Each material have characteristic that good different each other of advantage and weakness.

Concrete and brick have massif structure, concrete are very sturdy and strong structure. Loss both the material is to big weight by itself.

Bina Nusantara 6

Wood very abundance in Indonesia, its cheap price relative but its loss short building age effect of natural decay of white ants problem and material.

Steel of Hot Rolled conventional have lacking of that is weight alone big structure and problem of rust.

Bina Nusantara 7

Especial consideration in chosen building material is precisely utilize, lightly is, free treatment also economic and efficient. For that structure materials alternative able to wear steel of cold formed or recognized with light steel.

Excellence of Light Steel:

1. Rustproof, Anti white ants and do not molder.With existence of coating, light steel profile will be rustproof.

2. Light but strength and is sturdy.Construct light steel easel only 9 – 10 kg/m2, lighter than wood easel (15 – 18 kg/m2) and steel easel (20 – 28 kg/m2)

3. High accuration and also quality of uniform..Light Steel profile come from chosen material with its clear quality and processed to use sophisticated machines with computer control, so that yielded by profile which is high accuration and quality of uniform.

4. Is not flammable and do not creep fire.Is not ligneous, steel will not burnt and creep fire. But strength melt him equal to steel of hot-rolled so that protection coming from gypsum needed to detain the make-up of heat accepted by steel.

5. Relative is not big and dwindle effect of weather.6. Easy to in installation.

Manufacturing and easy installation, because amputation of flimsy profile very quickly and tacking on using screw self-drilling. Light structure. But to get result of perfect installation have to remain to be conducted by past master.

7. Environmental friendliness.
