High Strength Steel Tie Rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as , grade 785, grade 830, grade 930, grade 1080 etc. Post Tension Bar,Tie Bar Construction,Post Tension Rods,Post Tension Bar For Bridge SHANDONG LE REN SPECIAL STEEL CO., LTD. , https://www.sdbrightsteelbar.com
I. Overview The U.S. Refrigerated Temperature Recorder is a series of data loggers designed for ultra-low power consumption and long-time temperature data recording. The product can be used to record temperature and humidity parameters at regular intervals in accordance with the configuration time interval, and can transmit the collected data to a computer for processing, drawing charts; widely used in agricultural laboratories, industry, environmental protection, health and epidemic prevention, storage and transportation, museums, Greenhouses and other fields. This product uses imported sensors, imported high-energy lithium battery power supply, low power consumption technology design, no external power supply, small size, small power consumption, high precision, can work continuously for more than three years. Powerful data processing capabilities: RX series temperature and humidity recorder is equipped with the supporting record data analysis and processing software, using the popular WINDOWS interface; can complete the setting of temperature and humidity recorder working status through a simple operation, complete the reading of temperature and humidity recorder history data, also The current measurement parameters of the connected recorder can be read. The read history data can be output in TEXT or EXCEL format, processed by MICROSOFT EXCEL program, draw line charts, pie charts, curve fitting and so on.
