Wo Sang has been trading in non-ferrous metal scraps since 1956, and we concentrated solely in domestic trading in Hong Kong during our earlier years. However, Wo Sang underwent expansion and established our branch office & metal scrap yard in Nanhai, China in 1990. After the establishment of our metal scrap yard, we purchased metal scraps from domestic trading companies in Hong Kong , and sold to domestic processors / factories after simple process of sorting and grading in China. In order to increase our sales volume & improve quality of material, we participated in international trading and initiated our direct purchase from suppliers overseas since 1997. As an accomplishment of our effort for quality control and honesty, we have maintained a great business relationship with our supplier overseas and scrap processors / factories in China. As of today, Wo Sang has not only possessed experiences of international trading between Mainland China and foreign countries; but we also act as bridge between suppliers overseas and local scrap processors in China since 1990.
