Top roof and wall thickness of 0.4 to 1.6 mm; or silo is used for load-bearing floor thickness of 2 to 3 mm or more. Wave height is generally 10 to 200 mm. When not reinforced, its height to thickness ratio should be controlled at less than 200. When using the full-length roof, the slope can be 2 to 5%, the deflection does not exceed l/300 (l To calculate the span length). Oil processing of the application in the construction of the waveform shown in Figure [pressure plate commonly used waveform diagram].
Pressure plate because the original plate is thin, anti-corrosion coatings directly affects the quality of life, in order to meet requirements of processing and rust, coated steel basis having the relevant provisions of the inspection. Under normal circumstances thin steel plate can also be used according to requirements by the pressure-type anti-rust paint and then painted or stainless steel sheet of the original board.
Pressure plate for industrial plant roof, siding when no insulation requirements in the general case, each square meter of steel is about 5 to 11 kg. There insulation requirements, the available machine for pellets, glass wool, foam, etc. for insulation. Combined pressure plate made of composite slabs and concrete, eliminating the need for formwork and as a load-bearing structure. At the same time to strengthen the pressure plate and concrete binding force, should be pre-welded on steel studs or oppression bidirectional stiffeners.
