Galvanized square tubing is carbon steel tube that has been hot-dipped in a protective zinc coating, creating a durable barrier against rust. This process ensures longevity in outdoor or high-moisture environments. Manufactured to meet ASTM A500 Grade B specifications, this tube combines the strength of steel with excellent weldability, making it a practical choice for structural applications.
The 3-inch square profile offers substantial structural integrity, making it suitable for medium-duty frames and supports. Common uses include equipment frames, gate construction, handrails, carports, and structural members for utility trailers where strength and weather resistance are critical.
