Cold-rolled ribbed steel as a construction steel, concrete structure incorporates national norms in these countries the weight of ribbed steel, cold-rolled ribbed steel bars have been widely used in construction, highways, airports, municipal, hydroelectric pipeline. 1994, the annual output of 4.5 million tons EC. In China's neighboring countries ribbed steel standard, Singapore and Malaysia have long been in the building and civil engineering works ribbed steel is widely used in the production line, the amount of annual use only cold-rolled ribbed steel bars in Singapore in more than 150,000 tons. Tensile properties of cold-rolled ribbed steel bars should be at least equal to 90% of the total number of trials or greater than the specified property values, the individual test results shall be not less than 95% of the specified property values. Cold-rolled ribbed steel welded mesh countries mostly in the form for the project, with a small amount of straight bars on site banding. Whether straight bars or welded mesh, have implemented industrial production ribbed steel bars, according to the construction schedule requirements in batches to the construction site, simply press the reinforcing steel bar chart placement, without any further processing.
