Galvanized Pipe Schedule (40) - 4 Inches
This 4-inch nominal pipe size (NPS) Schedule 40 Galvanized Steel Pipe provides superior corrosion resistance due to its hot-dip zinc coating. Conforming to ASTM A53 Grade B, it delivers 60,000 PSI tensile strength, making it ideal for structural columns and industrial fluid transport. In stock Los Angeles.
- Galvanized Steel Construction
- ASTM A53 Grade B Certified
- 60,000 PSI Tensile Strength
- Superior Corrosion Resistance
Galvanized steel pipe is carbon steel that has been hot-dipped in a protective zinc coating, creating a durable barrier against rust. This process ensures compliance with ASTM A53 Grade B standards, providing a minimum tensile strength of 60,000 PSI and excellent weldability. Note that the zinc coating must be ground away from weld zones to prevent hazardous fumes. Its robust, low-maintenance nature makes it a reliable choice for outdoor and high-moisture environments.
As a large-diameter pipe, this 4-inch NPS size is ideal for demanding applications. It is commonly used for main water lines, industrial process piping, structural columns in buildings and canopies, and for creating heavy-duty safety barriers and guardrails where significant strength and flow capacity are required.
