This specialized pipe combines three key features: a 4-inch galvanized seamless steel pipe (for strength and corrosion resistance), an integrated ground rod (for electrical grounding), and a plastic end cap (to protect against debris and moisture). It's widely used in electrical systems, telecom towers, and outdoor infrastructure-where reliable grounding and durability are critical. Common grades include Q235 and Q345, meeting ASTM A53 and EN 10216 standards.
