For connection to a conventional steel or heavy steel welded joints and connections used bolt nut. For mild steel truss connections between each other truss in disposable screw self drilling screw or mild steel. Use disposable screw is recommended only because when used repeatedly, the drat of mild steel likely already damaged. This screw is used repeatedly when the sharpness of the screw eye is reduced.
Reinforcement in this connection are very important because in this connection the strength of lightweight steel roof structure. If there is a loose screw on the connection then the connection strength to be reduced. So keep in mind when installing the power of the screw. should not obscure the eye turning at the time of installing the screw too much because this could make a mild steel screw became loose. While the number of bolts on the connection can not be less than 2 fruits or determined by the design engineer and light steel structure is also influenced style truss rod of mild steel or expenses that are above the horses from the range of mild steel roof.
