For this customer, We have established a stable 5-year partnership with a renowned U.S.-based steel pipe distributor. This client consistently procures fixed-specification ERW steel pipes from us, which are widely used in building structures. Over the years, our commitment to exceptional product quality and proactive service optimization has made us a trusted partner in their supply chain.

This time, the product required by the client is still hot-dip galvanized ERW steel pipe, The material is Q235B and the size is 48.3mm x 3.25mm x 7.32m. For a long time, the customers have been consistently purchasing this size of galvanized ERW steel pipe.

For this product, we usually follow two steps. First, we produce black steel pipe of the corresponding size. After that, we wait for the customers to complete the inspection. We will apply hot-dip galvanizing to the black steel pipe.

When we finish all of the process, we will take photos and videos to the customers for check. Once the customer confirms that the steel pipes are in good condition, we will confirm the shipping time with the customer's freight forwarder. Finally, the steel pipe are transferred to the Tianjin Port for shipping.
