Jiangsu Lianzhong Metal Products (Group) Co., Ltd

Quality control is basic but the most important point for qualification of the steel pipes/tubes&fittings. Both advanced inspection&test equipment and device and skilled staff are involved in the systematic quality control procedure.

We carry out in-production supervision and after-production inspection for our pipes/tubes&fittings. We ensure that the products are produced,tested,and inspected strictly according to standard specification under supervision of our QA engineer during production. After-production inspection is carried out in house at our site by our own engineer with our own equipment&device.
