We have always firmly believed that when our customers purchase, the biggest pain point inside is the fear of buying the wrong one. For example, the standard is wrong, the steel grade is wrong, the dimensions are wrong, the dimensional accuracy is wrong, the delivery condition is wrong, and the surface condition is wrong. If it is a small detail wrong, it may mean that the material to buy is only a pile of steel scrap, the value of at least 80% loss. Therefore, we believe that pre-sales technical support is very important. We also expect our customers to place the same emphasis on pre-sale technical advice as we do in the entire supply chain management. Because we want our customers to buy right, not just buy the cheapest products.In the pre-sale technical support, we will thoroughly understand customer needs, fully communicate with customers, and discuss the most suitable procurement plan.
