Secondary steel pipe, often referred to as surplus or reject steel pipe, is repurposed from excess inventory, decommissioned projects, or inspected rejects that still meet structural standards. This pipe is typically more affordable than prime steel, making it a cost-effective choice for structural applications. While they may show minor imperfections, they are rigorously tested to ensure durability and functionality. Secondary steel pipe offers an eco-friendly option by reducing waste and promoting material reuse in various industries.
