The correct answer is: Building codes

The use of cast iron steel pipe in many commercial buildings is largely influenced by building codes. These codes set specific standards for plumbing and mechanical systems, ensuring safety, durability, and functionality within structures. Cast iron pipe is known for its ability to handle high pressures and its excellent sound-dampening qualities, which makes it a preferred choice in commercial settings. Moreover, the durability and fire resistance of cast iron contribute to compliance with various building codes that mandate the use of certain materials to ensure safety and longevity in construction. These regulations play an essential role in the selection of pipe materials to meet the requirements established for commercial buildings, which often seek to combine functionality with adherence to safety standards.
