Tianjin Metallurgical Steel wire rope and Cable Group Co., Ltd is composed of advantage assets from five mainstay enterprises: The Second Prestressing Wire Co., Ltd of Tianjin Metallurgical Group, Silver Crane Metal Products Co., Ltd, Tianjin Tiansheng Steel wire rope Rope Co, Ltd, Huanzhong Wire Ltd of Tianjing Metallurgical Group and Tianjin Green Ecological Technology Co., Ltd. The main products includes the low-relaxation prestressed strand, low-relaxation unbonded prestresssed steel strand, low-relaxation unbonded prestressed hot-dip galvanized steel strand, prestressed wire, steel wire rope, coating wire, green grid and other five series with more than 1000 specifications and yearly production capacity of 700,000 tons. It stands in the leading position in China. Among them the yearly production capacity of low-relaxation unbonded prestressed hot-dip galvanized steel strand reaches 80,000 tons and 180,000 tons for the low-relaxation prestressed strand.
The location of production base for low-relaxation prestressed strand is of good development advantages. In the west is Jin-jing highway, in the south the Tianjin outer ring road, in the north Jingjintang expressway to Tianjin port. It enjoys very convenient transportation. Our company possesses strong technical forces. We have metal products experts with national title in charging of the technology management and product development. We have 12 technicians with senior professional titles, 45 technicians with secondary professional titles and 175 technicians with junior professional titles. Our company attaches great importance to the development trend of technology on prestressed products. We have recruited eight experts as technical advisers from the department and academy of national planning, research and design. We also join in many relevant social science groups dedicating in the promotion and manufacture of prestressed products, as well as the development of new products.
We have four production lines for low-relaxation prestressed strand in all, among which two were imported from Germany and Italy respectively. We are the first manufacturer to obtain the GALFAN patented technology and production license of ILZRO and introduce the GALFAN production line in China. In 2006, we invested ￥6,000,000 in importing the EMW galvanizing technology from New Zealand to apply it in hot GALFAN (zinc-5%aluminium-rare earth alloy coating) strand production line. In 2008, we invested ￥45,000,000 in introducing the RZ120-9 bull blocker from Italy and the ISF5 low-relaxation stabilizing production line. In 2004, we drafted the national standard (GB/T20492-2006) for zinc-5%aluminium-alloy coated steel core wire, steel strand commissioned by the National Bureau of Standards. It came into effect from February 1st in 2007. We have advanced equipments and complete test method. The support of wind, water, electricity and gas can meet the real production needs.
Now, the low-relaxation prestressed strand, steel wire rope and other products are applied in 30 provinces, cities, and autonomous regions (including Taiwan province) in China. Some of the products are even sold in South Korea and Thailand. They are widely used in construction field, such as long-span bridge, high building and cement product.
