Specifications

  Qingdao Histro Steel Towers Co., Ltd. established in 2001. Our company has the ability of constructing and building broadcasting television towers, all series of communication towers, electric iron towers, microwave towers, and steel structures. Our output value was US$160 million in 2008.

     Our company is headquartered in Jiaozhou City, Qingdao, Shandong Province, and has branches in Beijing, Inner Mongolia, Chongqing and Xinjiang. Our production base takes up an area of 110,000 square meters with factory building of 30,000 square meters. We have total assets of over US$40 million including circulating fund of US54.5 million. There are 480 regular staff members in our company now, among whom 46 professional personnel have all kinds of economically professional titles including 3 senior engineers & 5 national first- class registered construction teachers.

Since our company was set up in Aug. 2001, we have built up more than 3000 broadcast communication towers with height between 50 and 200 meters in the whole country, as well as over 8000 power towers for transmission electricity. The indexes of the towers, such as vertical degree, reach or exceed the national standards.

    ISO9001 quality system and MBO can be applied. Security management consciousness must be heightened. A consistent total management with various systems would be formed to form a running-system which unites duty, power and benefit.

    In order to take up the production capacity, our company invests US$20 million in equipment. There are 4 digital controlled angle production lines, 1 numerical bending machine, 2 automatic connecting-plate machines, 2 digital controlled flame cutters, 80 welding machines, all kinds of drill machines and punchers, a 1:1 lofting platform, and other equipment in our company.

Since our company was established, an advanced lab has been set up. There are 15 professional staff members in the lab and the lab is equipped with universal testing machines, flaw detectors, elemental analyzers, and other equipment.

    Our company had been awarded as 'the Enterprise Observes Contracts and Keeps Promise' by the Industrial and Commercial Bureau of Qingdao from 2001 to 2012 in succession.

Production of steel-based structure is one of the main types of building structures. Steel is characterized by high strength, light weight, rigidity, and therefore for the construction of large-span and super, super-heavy-duty building is particularly suitable; materials, homogeneous and isotropic is good, an ideal elastomer, the most consistent with general engineering basic assumptions of mechanics; material plasticity, toughness is good, there is greater deformation, can well withstand dynamic loads; short construction period; its high degree of industrialization, mechanization can be a high degree of specialized production; processing of high precision, high efficiency , sealed good, it can be used for construction of gas cylinders, tanks and transformers.
The disadvantage is the poor fire resistance and decay resistance. The workshop is mainly used for heavy-duty load-bearing skeleton, by the power plant load structures, shell structures, high-rise tower and mast structures, bridges and libraries and other large-span structures, high-rise and ultra-high-rise construction.
