1.We have a variety of steel pipe production lines:
① 12 galvanized steel pipe production lines;
② 6 hot-rolled pipe production lines.
All the operation are controlled by computer automation and other advanced equipment. Meanwhile, our production process strictly conforms with the quality management system of ISO9001. At present our company is planning to build another new plant, committed to further expand the scale of production and processing, in order to better service more potential customers in the long run.
2.our warehouse is a kind of indoor installation which can prevent rain from eroding steel pipes. After production of steel pipe, we also have a indoor package so as to protect products without rain erosion. All these measures are taken into consideration in the interest of our customers. Under the harsh environment such as rainy or snowy, we can also handle our products including packing because all the activities with regard to steel pipes are processed indoor. So no matter what happened your order can be placed according to our original plan which can avoid a delayed delivery date.
