In 2015, one customer from Sri Lankan on Alibaba send an inquiry to purchase hot-dip galvanized bolts with nuts &washers, and stud bolt. The products are used for tap water pipes, it is one government project with high requirements. Suppliers must have 5S quality management system. Our company attaches great importance to the project, we supply many certificate documents and production workshops, testing equipment for inspecting, finally our company  passed the qualification certification.  

The certificates are as follows: ① raw materials ② mechanical properties of screws ③ hot galvanizing test report ④ SGS certificate

The customer realizes that our company is able to accept the project and ask for quotation. We considered several schemes, studied the raw materials, production process, heat treatment and hot-dip galvanized surface, and finally calculated the price from the customer. Send the sample to the customer first, and the customer will pass it at one time. We have professional testing equipment for hot galvanizing, and the coating has reached international standards; The nut should be reamed; Because hot-dip galvanizing is different from other surface galvanizing, we have strict requirements for factories.

The final customer's first order is 1X20FT, payable at sight. We strictly control the quality. Before delivery, the customer needs a third-party inspection. SGS successfully checked the order and delivered it successfully.
