What type of material is required for horizontal guardrailing?

The requirement for horizontal guardrailing is typically met with three-inch Schedule 40 steel pipe due to its strength and durability. This material is preferred because it provides robust protection and support in various environments, especially in the transportation and delivery sectors where safety is a key concern. The structural integrity of steel pipe makes it capable of withstanding impacts and harsh weather conditions, ensuring that it remains effective over time.

Other materials, such as wood, while historically used, may not provide the same level of durability and resistance to environmental factors. Cement, although sturdy, can be unyielding and is less versatile for rail installations. Plastic might be lightweight and resistant to corrosion but usually lacks the strength required to meet safety standards in guardrailing applications. Utilizing three-inch Schedule 40 steel pipe ensures compliance with safety regulations and enhances the overall safety of operations.
