BS1387 Class A/B/C Galvanized Steel Pipe
BS1387, also known as British Standard 1387:1985, is a specification that outlines the requirements for seamless and welded steel tubes suitable for low-pressure conveyance of gas, water, and other fluids. The standard classifies these pipes into three categories: Class A, B, and C, based on their wall thickness and mechanical properties. Galvanized BS1387 steel pipes are further treated with a protective zinc coating to enhance corrosion resistance.
