Roof sheet is generally used for cold rolled steel sheet, galvanized steel sheet, color steel sheet and other different types of thin steel sheet, the thickness is generally 0.15 to 1.2 mm, and then after rolling, cold bending, its section can be V-shaped, U-shaped, etc., the section can also be trapezoidal or similar waveform, profile roof sheet is also known as building profiled steel sheet or corrugated steel sheet for short. The quality of anti-corrosion coating directly affects the service life of roofing sheet because the original plate is very thin. In order to meet the requirements of processing and anti rust, the coated steel plate should be inspected according to relevant regulations. When roofing steel sheet is used as panel and wallboard of houses in industrial factories, the steel consumption per square meter is about 5-11kg under the condition of no insulation requirement. When insulation requirements are available, mineral wool boards, glass wool and foam plastics can be used as insulation materials. The composite floor made of metal roof tile and concrete can be used as load-bearing structure without wood formwork. At the same time, in order to strengthen the binding force between profiled steel plate and concrete, it is better to pre weld studs on steel plate or press two-way stiffeners.

The remote maintenance and positioning system of the pump truck adopts the world's leading GPS satellite positioning technology, GSM/GPRS global mobile communication technology, GIS geographic information technology and computer network communication and data processing technology, and is developed on the basis of the existing GSM/GPRS public network. A set of engineering equipment remote maintenance and positioning system, its various performance indicators have reached the international advanced level. The system relies on 21+3 satellites distributed in space, which can locate the devices distributed throughout the country and even outside the country, and adopt GPRS technology to realize the monitoring and control of the terminal equipment, and can know the working place of any equipment at any time. Health status, and can be set, maintained, and operated remotely.
China's first GPRS pump truck remote maintenance and positioning system developed by Zoomlion Electric Branch has been officially networked. Four pump trucks and on-board pumps equipped with this equipment have been working on the site.
