Jiangmen steel structure: Lightweight steel roof slope is generally small, often below 6%, more rain in SOUTH roof area of ​​this structure leaking more common, there is a large area of ​​water leakage, light windows and roof drip binding sites and the like. The reason for the formation of water leakage reasons nothing more than self-tapping screws, color steel lap, roof tile, pumping heart rivets, color steel roof Exalted cause deformation and windows and other decorative lighting plastic parts rain shedding several reasons.

1, roofing screws and fasteners leaking
This phenomenon is more common, mainly in the double and single color plate color steel roof. During the construction process, tapping strength is too heavy, too light, since the screws missed, hit the ramp, can make it a self-tapping rubber gasket deformed, or the formation of a concave shedding, causing roof leaks and drip through the accumulation of cotton insulation, plot less to more, the formation of multi-point leakage. In addition, self-tapping malposition, miss color steel purlins under one of the important reasons is caused by leaky holes formed directly. This water leakage in a single layer color steel roof insulation system does not have the structure may not be obvious, mainly because of the rain through plate and purlin contact areas directly dispersed after leak, not necessarily fast drip.

2, color steel lap leakage
Horizontal and vertical lap joint lap joint, color steel lap leakage, if met Choi steel Wabo low or no rain over large Wabo, easy to form a large leak, leakage points and difficult to find, once formed easy maintenance. More common in the curved roof. The main reason is the overlap between the two plates is not tight, self-tapping not played in the formation of voids, etc.

3, leaking roof tile
Tile roof leaks. In the light steel roof construction, roof tile caused by the leakage is a more common phenomenon. During the rainy season, especially when a large amount of rain, the rain splashing through the lower ridge two color steel butt at the gap, forming a large area leakage.
Jiwa prevent leaks in the construction should be adopted to increase the length of the ridge flanging, every Wabo site notches, gluing the seams.
