Profiled steel plate yaxing gangban English name: profiled steel sheet
The thickness of the roof and wall is usually 0.4 to 1.6 mm; when used for bearing slabs or silos, the thickness is 2 to 3 mm or more. Wave heights generally range from 10 to 200 mm. When not reinforced, its height to thickness ratio should be controlled within 200. When a long roof panel is used, the slope can be 2 to 5%, and the deflection is not more than 1/300 (l is the calculated span length). Some of the waveforms currently used in construction are shown in the figure [Common Waveforms for Profiled Steel Sheets].
Because the original plate is very thin, the quality of the anti-corrosion coating directly affects the service life. In order to meet the processing and anti-rust requirements, the coated steel plate needs to be inspected according to relevant regulations. Under normal circumstances, the thin steel plate can also be coated with anti-rust paint after pressing according to the application requirements, or the original plate of stainless steel thin plate is used.
When the profiled steel plate is used as a panel or wall panel of an industrial plant, the amount of steel used per square meter is about 5 to 11 kilograms in general without insulation requirements. When there is insulation requirement, mineral wool board, glass wool, foam plastic, etc. can be used as the heat insulating material. The profiled steel plate is combined with concrete to form a composite slab, which can save the wooden formwork and can be used as a load-bearing structure. At the same time, in order to strengthen the bonding force between the profiled steel plate and the concrete, it is preferable to pre-weld the stud or press the two-way stiffener on the steel plate.
