The core advantages of China's seamless steel pipe cylinder tubes in the international market are high cost performance, standard compliance, and stable supply chain.
In terms of procurement channels, our company directly connects with steel mills (such as China Baosteel, Baotou Steel, Hengyang, Tianjin Steel Pipe) to obtain lower prices.
High flexibility, one-stop service for both small and large orders. For small orders, we will give priority to finding inventory spot, and for large orders, we will work with steel mills to formulate production scheduling.
We provide FOB and CIF prices to help customers solve logistics, customs clearance and other issues.
34CrMo4 and 37Mn produced in China are 20%-30% cheaper than European products. We can stably supply large quantities of orders. We have mature qualifications and operational capabilities for familiarity and provision of standards. We also have long-term stable freight forwarders for freight companies.
