Carbon steel pipes are low carbon content, better overall performance, and better coordination of strength, plasticity and welding properties. The complex chemical and physical properties of the various grades of carbon steel pipe allow for a broad range of service usage. Carbon steel pipes are mainly used in building structures such as factory buildings, bridges, ships, and general pipelines for conveying fluids.

With the support of the most professional steel manufacturers and a large number of customers, we can not only provide you with ordinary steel but also help you find very personalized steels, such as special steel grades, Special sizes, special craft shapes, etc.

As a trusted partner, we have the products you need, when you need them. From full lengths to custom cut pieces, we can handle the job in a timely manner and to your exact requirements. We carry pipe in many different sizes, lengths and specifications. You can find product specs for our welded and seamless steel pipe in our catalogue.

North Steel adopts standard export shipping packaging and bundles steel strips according to the size of the carbon steel pipe. According to our delivery experience, a 20-foot container can hold 22 tons of carbon steel, and a 40-foot container can hold 25 tons of carbon steel. For larger orders, we use bulk vessels to transport you, and the price is cheaper. Also, we can customize the packaging according to the needs of customers.
