Construction method folding Edit this paragraph 1, lap roof: roof overlapping sub-horizontal overlap and vertical overlap with the roof slope in the same direction, said overlapping vertical overlap, a direction perpendicular to the slope of the roof called the lap horizontal overlap. In the metal roof level lap first coat of grassroots waterproof coating, when it is still wet, the 20 cm wide woven polyester fabric sewn embedded therein, from top with grassroots paint full infiltration woven polyester fabric sewn, as well as all dry, then brushing a grassroots paint, brushing the last two surface coatings. Vertical lap roof coated metal roofing grass coating, when it is still wet, the 15 cm wide woven polyester fabric sewn embedded therein, from the grassroots paint top with woven polyester fabric sewn full infiltration, as well as all dry, then brushing a grassroots paint, brushing the last two surface coatings. 2, the metal roof projection (such as cable anchors, vents, fans, mouth, etc.): cutting the size and shape suitable woven polyester fabric sewn, according to the technical requirements of a good cut, coated with a layer around the projection grassroots paint, the cut Good woven polyester fabric sewn layered over it, and then from the top with the grassroots paint full infiltration of woven polyester fabric sewn to ensure that no bubbles, no wrinkles. Full dry and then brush a grassroots paint, brushing the last two surface coatings. Typical properties The main application of metal materials (steel tile, aluminum, stainless steel, etc.), lighting tile, aluminum panels, sun panels, stone, concrete and other strong bond, especially sealing, high temperature resistance, fatigue resistance and following the good performance good tensile strength and elongation, deformation and cracking of the interface adaptability UV protection, extend the useful life of the substrate aging resistance, weather resistance and corrosion resistance can be good with a strong acid-alkali resistance waterproof, burning, mold, bacteria, algae and other anti-flexibility, wide area suitable for -50 ℃ ~ + 88 ℃ of use, excellent flexibility at low temperatures is still possible human stampede, with the exception of trampling damage 1. Surface smoothness the appearance of superior quality; 2. easy installation, high efficiency, low cost compared to handmade; 3. Rockwool core material is a natural rock, iron blast furnace slag and other high temperature melting into wire, and then curing. Has better sound-absorbing, sound insulation and good fire resistance, the test proved that it has a fire resistance of 650 ℃, fire rating to A-level; 4. Interface tight conduction of heat is not easy; the furnace temperature 180 ℃, the outer plate a temperature below room temperature + 5 ℃. 5. poor load-bearing capacity. Rock wool sandwich fields of application] widely used in steel plants, simple activities room roof, wall, ceiling and air clean room partition 5. transport When the room dedicated wall plates, steel wall panels at the fulcrum pick the length of not more than 1.0 meters, in order to ensure that the material will not deform and wear. Once there are more than two meters above the wall, you must pick the appropriate plate and in its entirety the tying good at the end, in order to avoid the rear of a car shock wave caused by excessive deflection surface is damaged room wall. 6. The sheet handling when two while lifting to avoid damage to the surface of the oxide film or coating. Second, the room wall during the installation should pay attention to the following points: 1. Room wall during the installation process, should use special tools, construction workers should be in the construction room color plate color plate room before checking tool is a complete range, the specific content of the work needs to be checked is the main material and accessories are complete and not missing is intact It can be used for special measuring tools should be seized by custom and develop a good, if not meet the requirements should be timely replacement and maintenance. 2. Prior to installation, you should first clear the construction area, and check the site conditions with the design of the wall construction plans installation requirements, as well as fire and dust static shielding technology meets the conditions and regulations, need to refer to the following aspects:
