Henan Liaison Import&Export Co., Ltd (LIAISONSTEEL)was established in 2009,after 5 years development, our company have a mature export system. From the beginning of selling steel plates and pipes,then steel products’ primary processing which cover steel plate’s cutting,splitting, the pipe’s bending, until now we can do the steel fabrication on 680mm thick plate,customer’s high requirements improved LIAISONSTEEL’s growing. Because our qualified products and a timely delivery,we became a steel plate fabrication cooperator with customer from Africa, Australia, Singapore, Thailand and several countries from South America.
Our superiority:
Supplying abroad standard ASTM,EN,JIS steel plate and pipes.
Supplying plant construction materials such as H beam,I beam, U beam,C channel.
Supplying large-scale section’s welding.
Supplying clad steel plate.
Supplying steel plate or pipes’ fabrication be used for heavy equipment, water power station’s gate, industry mould, working table of machine tool,parts.
