The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste. After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material. 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. It can be loaded loose in 20â?? heavy duty container. Please feel free to contact us for further details.

Steel products refer to solid straight steel products with a certain section shape and size, including wire, profile and plate, which are formed by plastic processing except pipes. It can be divided into hot rolling, cold bending, cold rolling, cold drawing, extrusion, forging, hot bending, welding and special rolling according to the production method. It can be divided into railway, shipbuilding, mining, structure and construction according to its use. According to the material can be divided into carbon steel, alloy steel and stainless steel. At the same time, these steel products can be reprocessed to form semi-finished products or finished products to meet special requirements. We can according to the customer's different needs, according to the drawings or samples for reprocessing production.
