A spiral steel pipe with an outer diameter of 325mm and a wall thickness of 7mm weighs around 67.6kg per meter.

A coil of spiral steel pipe is usually offered for sale starting from:

High production difficulty: The equipment and processes required for spiral steel pipe production may be beyond the capability of small-scale manufacturers. As a result, these manufacturers might sell spiral steel pipes in quantities starting from one, in order to reduce production costs. Custom services: Some spiral steel pipe manufacturers offer custom services, producing according to customer specifications. In such cases, manufacturers may provide a starting quantity of one to meet individual customer needs. Low market demand: In some markets, such as rural areas or remote regions, demand is low, and manufacturers might offer a starting quantity of one to cater to these markets. It's important to note that spiral steel pipes sold in quantities starting from one are typically more expensive due to higher production costs. Additionally, if bulk purchasing is required, it is recommended to choose manufacturers with scale and strength to ensure quality and reasonable pricing.
