Hong Kong Huaxing Shipping Co., Ltd. is specialized in the transportation of large quantities of sea sand.

      Sea sand is a kind of natural sand collected from beach or seafloor. Due to the erosion of sea water, the particles are smooth and hard, but they contain salt, shell and other impurities. The chloride salt in sand is very harmful to concrete and reinforced concrete. It must be washed with fresh water to make its content not exceed the relevant standard.
