U steel support Mainly characteristic: bear big pressure, support time is long, easy installation and not easy to deform etc. Mainly application: mainly used in mine tunnel, second support of mine tunnel, and the support of mountain tunnel. It is used as the main profile steel of the compressible metal support of tunnel, U-shaped steel is widely used at domestic and overseas. However, the cognition of the performance and requirement of U-shaped steel are not consistent, therefore, the section shape, geometry and material of u beam are different. The model of u beam produced in China mainly includes 18U, 25U, 29U and 36U. The first two is the sixties product, belong to the waist position. The latter two is the eighties product, belong to the ear position. In GB/T 4697-2008, the model of 40U is added in addition to the above four models.
U shaped steel: U shaped steel is a kind of steel that the cross section is like the English letter U. Basic information Chinese name: U-steel support Application: Used in mine tunnel Characteristic: Bear big pressure Steel type: The type of the sixties Usually type:25U, 29U, 36U

The Tire derived Steel or Tire Wire Scrap is a light melting scrap obtained during the shredding and granulation process of used tires. Generally 10% - 20% of the weight of an old passenger car tyre usually consists of steel. An average shredding plant produces about 100-200 MT of steel tyre wire and its quality can vary according to technology, storing and management systems adopted by the producing plants. We can provide tire wire scrap that still contains up to 20% rubber/fiber. This percentage is detected by manual separation test. The material can be loaded loose in 40 HC container. For further details, please feel free to contact us.

Waste Specification: European Classification: E46 EWC Code: 19.01.02 Basel Code: B10 10 The material is loose steel scrap processed through an incinerating plant for domestic waste followed by magnetic separation, fragmentized into pieces and consisting partly of tin coated steel cans. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. Due to the scrap dimensions and the material conditions, this particular scrap, should be carefully evaluated first, by the end users, to confirm its adequate recovery ratio and its suitability to be re-melted in the electric arc furnace.
