Project Description


Anchor Steel

Resin hot-rolled steel bar with seven advantages

  • The most reliable and high-quality raw material protection : The company owns Australia’s high-quality mineral powder base and adopts a reasonable mix of high-quality raw materials to provide reliable raw material protection for production.
  • The most advanced and accurate inspection system : Using Bruker S4 X-ray non-contact fluorescence analyzer from Germany, universal testing machine and impact testing machine manufactured by Tess Industrial Systems in the United States, all raw and auxiliary materials and finished products tested in the factory were inspected to ensure accurate data for each link. The indicator is fully controlled.
  • The most stable and stable quality product : “JB” brand hot-rolled ribbed steel bar for resin bolts is the most stable steel used in the country. The product has excellent concentricity and verticality, is easy to process, has high strength, high elongation, and ensures maximum use of mines. Anchor reinforcement safety.
  • Fastest quality classification: Different grades of resin bolts with different specifications will be produced with hot-rolled ribbed steel bars, which will be categorized by the sales company according to customer needs, and provide the user with test data for each batch of products sent to ensure the accuracy of product analysis data. Sexuality and timeliness, to meet the different requirements of customers.
  • The most elaborate and rigorous production process : From the raw material procurement, testing, ingredients, smelting, rolling, sampling to classification according to customer requirements, transportation and other links have MES system and process card control, so that products have traceability.
  • The most standardized production process control : Adopting the leading domestic bar production line designed by China Metallurgical Co., Ltd., Beijing Ruixin Long Products Co., Ltd., the company introduced new technology from Germany and implemented standardized process control to make the product have full strength and high material utilization rate.
  • Most intimate and perfect after-sales service : The company has professional and technical personnel to solve the problems encountered by customers in the production process, to the quality of customer feedback, and make every effort to achieve the province within 24 to reach the scene, within 48 hours outside the province to reach the scene, to ensure that the first time to come to the customer service.
