Evergrowing Resources CO.,Ltd
Evergrowing Resources Co., Limited was Located in Nanjing, China.
We have engaged in import and export of all kinds of ferrous and
nonferrous materials all over the world. Because we are top agent
of several different steel mills in Asia and Europe, so we have
ability to offer best quality products and services to our clients.
Till now, we have supplied products and services in Asia, Europe,
Africa, North America and South America. Following the trend of
market development, we have built our special steel processing
center in Jiangsu, China to do further processing on the products,
such as heat treatment (QT, N, ANN), rough turned, CNC cutting and
etc. We have extended our industrial train and enhanced the ability
to provide the auxiliary item, and thus strengthened our market
advantage.
Evergrowing aim:
