In the southern region, the most serious leaks color steel roof, metal roofing projects is particularly important, many owners will often react after last night still leaking water scene, the main reason is the construction of some easily leak location is not good cause risks, there are two points. First, because of the material properties of risks caused by leaking large thermal conductivity metal plate itself, when the outside temperature is changed greatly, due to environmental temperature changes due to temperature changes caused by shrinkage deformation of color plates and have a greater displacement at the interface, thus metal plate interface easy to produce parts hidden leaks. Special parts, due to the use of different materials to connect, such as steel parapet with great connections made through the ditch, with other parts of the roof light, due to the stress changes are not synchronized, resulting in leakage risks. Steel structure, since the structure itself in the role of temperature changes or wind load, snow load, etc. by an external force, the readily elastically deformed, the connecting portion is displaced to generate leakage problems. Second, the housing structure design or plate type defects caused leakage problems. In the fierce market competition, the construction side to undertake the task, and blindly reduce the cost, in order to save raw materials, structural design, reducing the slope houses, and even some less than 1/20, easy to produce water, causing the house leaks . Due to cost factors, the current pull-pressure light steel houses used by the majority of wave height lower plate (large effective area), and the width of a small lap, when the housing water, easily diffuse through the plate lap parts produce leaking. Geographical features in the structural design have not been fully considered defects caused by water: Currently in our light steel structure design, did not consider regional differences in climate and different waterproof measures, such as the rainy season in the south of waterproofing environment, coastal areas Season waterproofing and typhoons Environment Northeast snow melts waterproofing, and has its own structural characteristics, to use for the region waterproof material. Shenzhen fruit Seoul good waterproofing company main business areas: Where old and new concrete buildings to undertake professional water trap water shutoff (plant, expansion joints, high and low settlement joint, the parapet; exterior wall cracks, anti-leakage, Yupeng connecting joints, aluminum window frames leakage; day side, window, toilet, water towers, pools, swimming pool, elevator shafts, stairwells, basements) and other sporadic water trap with integral waterproofing.
