The cold-rolled ribbed steel bar is a steel bar with two-sided or three-sided crescent shape formed by hot-rolling wire rod through multiple cold rolling reductions, one pressing rib and eliminating internal stress. In 1968, Germany, the Netherlands, and Belgium developed successfully. Since 1973, it has been widely used in Europe (Germany, Austria, Italy, the United States, the United Kingdom, etc.) and has corresponding national standards. The International Organization for Standardization (ISO) has also established international standards.
UKO has been focusing on the production and processing of cold-rolled ribbed steel rolls (FO/CA/RT/RO/PR) for 16 years and is equipped with de-phosphorus sticks, straightening rolls, stress-relieving rolls, mandrels, and other steel wire rods. It can provide a one-stop service for customers and has ISO certification (GB/T 19001-2016 / ISO 9001:2015).
As a kind of construction steel, cold-rolled ribbed steel is included in the concrete structure specifications of various countries and has been widely used in construction engineering, highways, airports, municipalities, and hydropower pipelines. In 1994, the European Union produced 4.5 million tons per year. In China's neighboring countries, Singapore and Malaysia have long been widely used in construction and municipal engineering. The annual usage of cold-rolled ribbed steel in Singapore alone is over 150,000 tons. It can be seen that the market potential of cold-rolled ribbed steel bars is very large. UKO cold-rolled ribbed steel bars have been exported to no less than 80 countries. There are agents in Malaysia, Thailand and other places, quality service, and rolls. The high-cost performance of the UKO has won the praise of customers.
The strength grades of cold-rolled ribbed steel bars are roughly the same in all countries, both above and below 550Mpa, and the specifications are 4-9mm. They are used for ordinary reinforced concrete structures, such as cast-in-place slabs, foundation slabs and distributed ribs, and distribution of shear walls. Ribs, stirrups of beams and columns, etc. These ribbed steel bars rolled out by the cold rolling of UKO low-pressure sintering can be perfectly used in construction projects. The mechanical properties of steel bars specified in the international standard ISO10544-1992(E) are as follows: yield strength 500Mpa, tensile strength 550Mpa, elongation (standard gauge 5 times diameter) is 12% (Note: China's set elongation δ10 ≥ 8% Instead of δ5 ≥ 12%). The tensile properties shall be at least 90% of the total number of tests equal to or greater than the specified characteristic value, and the individual test results shall be not less than 95% of the specified characteristic value. Choose UKO professional cold roll suppliers to greatly improve your steel tensile properties and customize the ribbed pattern you want.
Most of the cold-rolled ribbed steels are used in the form of welded wire mesh, and a small number of straight steel bars are used for binding on the site. Among them, there are 19 welded wire mesh factories in Germany, belonging to 6 groups. Regardless of whether it is a straight bar or a welded wire, it is factory-produced and sent to the construction site in batches according to the construction schedule. The steelworkers need only lay them out according to the drawings, and no further processing is required.
UKO specializes in the production of hot and cold rolls, dephosphorization rolls, straightening rolls, drawing dies, over-line dies, and other wire tools, providing roll fittings for a wide range of wire equipment, greatly improving the production efficiency of cold-rolled ribbed bars and reducing raw materials and Machine loss. Our rolls are professionally tailored to provide laser engraving for our customers, and UKO customers have a lifetime after-sales service system.
