The secret of Xi ' an slimming steel underground industry chain a ton of steel added 760 yuan

According to the Chinese voice of "news in the vertical and horizontal" report, steel bar is the skeleton of the building, the strong or not directly determines the quality of the building, and recently in Xian has been artificially drawn "thin body" steel, and such a thin bar but through the whole underground sales chain became a "standard" of the construction of steel.　　Xi ' an trade and Industry Bureau of Law enforcement officers in XI ' an some steel factory inspection found that many labeled 10 mm, 8 mm specifications of steel, the actual measurement results are completely different.　　According to the relevant provisions of the State on the reinforcement processing, plate round a bar to allow cold drawing of steel bar straightening and remove the rust on its surface, easy to use. According to national standard, the cold drawing ratio of the plate round one grade steel bar is not more than 4%. In other words, the diameter of 10 mm of steel bar can only pull to 9.96 mm, the inspection was found to be only 6 mm diameter of the super pull steel.　　Such steel does not guarantee the quality and safety of the building at all.　　Super Pull Steel is more than the national standard of tensile steel, fine steel toughness greatly reduced, can not meet the load-bearing standards, and the reporter investigation found that many without any formalities of the "Black processing plant", the annual production volume is not low.　　At present, this kind of steel bar processing in XI ' an is no more than 100 ultra-tensile steel This "industry" has been quite large, these "slimming" steel processing plants outside the Lanhuo, not to processing units charge processing fees, and even pay their extra "kickbacks and wouldn't" to improve the product market so-called competitiveness. And so huge access, is responsible for inspection of building materials, to ensure the quality of building safety supervision why ignore it?　　A factory owner told reporters that when the processing plant to the supervision of the "benefits", these "thin body" steel bar has become a qualified product into the site.　　Professionals to calculate a sum, from the specification of 10 mm of steel to 9 mm, a ton of steel will be more than 380 meters, and virtually value-added 760 yuan, if a little more revenue will multiply, this is the processing plants and builders why the Super tensile steel bar reason. However, this high profit is to reduce the earthquake resistance of buildings as a price.　　When a house is subjected to an earthquake and other large external forces, the steel bars that become "brittle" by excessive cold pull will suddenly break, causing the house to collapse rapidly. Xi ' an urban and rural construction committee has been to all the city site for the use of ultra-pull rebar, Shaanxi province housing and Urban and rural construction department said that will be strict violations of the responsibility unit and responsible person.
