Sand & Aggregates
River Sand For Construction
We sell river sand in large quantity , we have capacity to supply river sand to all over the world contact us for price and sample .
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size.
We are into river sand/vibro sand, armour rock, boulders and aggregates/gravel business in the Philippines. We have more than 18 quarries in the Philippines. We could supply in quantity for local and international markets.
Aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural state or crushed, according to its use and application
Supplier: Cast iron skulls, cast iron borings and turnings, steels skulls, eaf skulls, plate iron, mill scale, metal scrap, incinerated scrap (e46)
We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.
Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00
