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.

Passenger turnover volume reached 751.104 billion person-kilometers, an increase of 60.59 billion person-kilometers, an increase of 8.8%. Since the beginning of this year, the railway department has grasped the law of passengers’ outflows, rationally allocated transport capacity, and used spring transport, summer transport, and small and long vacations as favorable opportunities for incremental passenger transport, continuously strengthened passenger transportation, and successfully completed the Spring Festival and Summer Games and the New Year’s Day, the Ching Ming, and May 1st. During the Mid-Autumn Festival holiday travel, a number of passenger indicators have reached record highs. The driving effect of new lines such as the Beijing-Shanghai high-speed rail is increasingly prominent. In addition, the railway department also adjusted the train operation map, optimized the structure of passenger transport products, improved ticket sales, improved the service environment, and achieved an increase in passenger traffic.
In terms of freight, from January to September, the total volume of cargo shipped was 2,929.70 million tons, an increase of 21,597 million tons, an increase of 8%. Among them, the volume of goods sent was 2.9952 million tons, an increase of 215.51 million tons, an increase of 8%, which was 74.9% of the annual plan, over progress of 2.53 million tons.

This year, the railway sector strengthened market analysis in accordance with relevant macroeconomic policies of the country, increased effective source organization, increased transportation efficiency, organized balanced transportation, and strived to increase Increase revenue. Each railway bureau implements the idea of ​​all-around and one-player chessboard, strengthens the flow of traffic, increases the volume of transfer at the boundary, ensures the smoothness of the trunk line, and at the same time does a good job of regional circulation transportation, continuously improves the transportation efficiency, and organizes balanced transportation. In the first three quarters of the year, the national average daily loading capacity of railways completed 168,112 vehicles, an increase of 11,192 vehicles, an increase of 7.1%. While transporting passengers and cargo, the railway department actively overcomes difficulties such as tight transport capacity, numerous construction tasks, and increased inclement weather. It attaches great importance to the transportation of key materials related to the national economy and the people's livelihood, increases the intensity of transport capacity, and ensures electric coal, grain, and disaster relief supplies. Transportation. From January to September, the national railways sent a total of 167.66 million tons of coal, 101.14 million tons of oil, 70.27 million tons of grain, and 64.01 million tons of chemical fertilizers and pesticides.
In the first three quarters, the total number of passenger and cargo transportation production targets for the whole year increased significantly year-on-year, but it is still very arduous to complete the annual business target. In the fourth quarter, all units of the whole line will take strong measures to implement various production and operation tasks throughout the year in accordance with the deployment of the ministry's group on implementing railway diversification. In terms of passenger transport, the entire road takes the opportunity of serving passengers to be the first to compete for excellence, exerting new maps and new resource effects, optimizing the train development program, implementing various measures to facilitate people and the people, and actively expanding the passenger transportation market. In terms of freight, the entire road focuses on expanding the volume of bulk cargo and striving to regain traffic. It has fully utilized the cargo capacity of existing lines to develop bulk cargo transportation, high value-added cargo transportation, container multimodal transport and intercity express transportation. , Optimize and improve the structure of freight products. At the same time, all roads will strengthen key regional and key line transportation organizations, further increase the number of north coal and south transport, and improve the coordination mechanism of transportation organizations among railway bureaus and roads in the northeast, northwest and southwest regions, and optimize the allocation of regional transportation resources.
In the first three quarters of the year, the national railway freight volume exceeded the annual plan
According to the statistics department of the Ministry of Railways, in the first three quarters of this year, the national railway passenger and freight volume achieved a substantial year-on-year increase, and all exceeded the schedule for the year. This laid a solid foundation for the completion of the annual passenger and cargo volume task.
