This is a A53 Galvanized Steel Schedule 40, 4"x 21' Pipe with a thread end. Electric Resistance Welded. (ERW) used for bending, flanging and standard welding jobs. Pressure tested complies with ASTM A 53 Grade B Type E (Electrical Resistance Welded). Galvanized steel pipe is compliant ASTM A53 specifications. ASTM A53 Steel is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications. Suitable for framework, gym equipment, awnings and much more. They offer versatility, simply cut to a custom measurement for your specific project needs with a metal saw. Coated in zinc, galvanized steel pipes are protected from oxidation and rust, which ultimately prevents deterioration of the pipe. They are a great option when you need to protect your steel pipes from a corrosive environment. The protective quality of galvanized pipe is created through a hot-dipping process, where the zinc then provides a protective layer that will rust away before any of the steel is affected. In terms of durability, a galvanized steel pipe can last well over 100 years, depending on the amount of corrosion exposure. Galvanized pipe maintains a wide range of benefits, suitable for use in highly corrosive environments. The semi-smooth, zinc finish of galvanized steel pipe provides a layer of protection that is not seen in other types of protective materials. The galvanized coating process protects the underlying steel from encountering corrosive elements that could deteriorate the steel and ultimately weaken its structural integrity. Main advantages of galvanized structural pipe include: Protects against corrosion and rust Increased structural longevity Overall enhanced reliability Affordable protection Easy to inspect Less repairs Rugged toughness Easier to maintain than standard painted pipes Protected by advanced ASTM standardization This pipe can be custom cut to lengths of your choice, please click "add cuts" to customize the exact measurements you need.
