How much should sheet copper for general applications weigh per square foot at a minimum?

The minimum weight of sheet copper for general applications is specified to be 12 ounces per square foot. This standard is important for ensuring the durability and longevity of copper installations, particularly in plumbing applications where material strength and resistance to corrosion are crucial. Using heavier gauge copper, such as 12 ounces, provides additional integrity and reduces the risk of damage or wear over time, making it suitable for various plumbing functions, including pipes and roofing.

The chosen weight of 12 ounces balances the need for strength with practicality in handling and installation. It also aligns with industry standards established by organizations and codes that govern plumbing practices, ensuring consistency and safety in plumbing systems.

Weights that are lower, such as 8 or 10 ounces, would not provide the necessary strength, which could lead to issues in the field, such as warping, leaks, or other failures. The option of 14 ounces might offer more strength but may not be necessary for all general applications and could lead to increased costs.

Therefore, selecting sheet copper weighing at least 12 ounces per square foot is a critical guideline for maintaining the quality and reliability of plumbing systems.
