Carbon Steel Steel Tube ASTM A53 API 5L DIN2448 St37.2 Round Black Seamless Steel Pipe for Pipeline and Structure
Carbon steel pipe is exactly what it sounds like - pipe made from carbon steel, a steel alloy containing iron and carbon. An incredibly durable material, carbon steel pipe is used in heavy-duty industries like infrastructure, shipping and chemical fertilizing.Carbon steel pipe is made of iron, carbon, and other elements. Black steel pipe is made of iron and other elements, but the main difference between the two is that carbon steel pipe has less carbon. This makes it harder and more brittle, but also allows it to be welded, machined, and formed more easily.

Based on various standard / different standard,
The surface requirements are not high can be ordinary bundled packaging after rainproof packaging The surface requirements are high, and have done positive or sprayed electrostatic film heat shrinkable packaging, wrapping paper packaging If the output requirement is particularly high, we will pack it in wooden cases or wooden brackets after the above packaging.
