Sand for building:
Our sand for building is explored from the deep riverbed under the red-stone alabamine mountain, the main contents of which are red-stone and yellow-white-stone alabamine rock, which is characterized by bright color, strong hardness, intensified resistance. With the clean deep underground water as the water source, sand for building is processed by 3 times removing clay, screening by grade, surface finishing and other special processes. Characterized by clean surface, circular and homogenous grain and low clay content, it is the best material of main reinforced concrete structure such as highway, bridge engineering and building construction industry.
