Highway, municipal and factory area guardrails are exposed to outdoors for a long time, requiring column pipe materials to take into account anti-corrosion, impact resistance and installation convenience.

Common Pipes

• Corrugated guardrail column: hot-dip galvanized round pipe (such as Φ114, Φ140) or square pipe column

• Fence net, isolation grid column: galvanized round pipe with column cap and connector

• Surface can use hot-dip galvanizing or hot-dip galvanizing plus dipping/spraying double anti-corrosion

Solution Advantages

• Galvanized layer resistant to rainwater, salt spray and temperature difference, long service life

• Round column matches corrugated beam plate and anti-blocking block, good buffering performance

• Can be fixed length, pre-drilled, meeting large batch centralized supply
