Relation between Chinese standard and international standard – Wind turbine foundation anchor bolt assemblies products

1-1

        Wind turbine foundation anchor bolt assembly is one of Anyang Longteng’s star products, and brings a high percentage of profit in recent years. Within our domestic market, Anyang Longteng is the top 3  in this area. We have built business relationship with many wind turbine company, technology company, engineering company, installation company, etc. With more than 12 years experience and professional team, Anyang Longteng would like to share more information with people who might be interested. 

        For overseas customers who is interested in purchasing our wind turbine foundation anchor bolt and cage, one of their questions is, whether a Chinese factory meet the international standards, or even their own standards?

 

        So here, with our experience and technician’s research, we post a converse table between standards:
