Thrie beam guardrail is manufactured from steel coil of a certain length. The steel plate is then punched, slotted to fit the thrie configuration. Common surface treatment is hot dip galvanized and plastic powder coated in yellow, green or other colors.

Thrie beam barrier can be straight or curved to suit different applications. Straight thrie beam barrier is often used as roadside barrier or median barrier to control the traffic. Sometimes modified thrie beam can be used as transitional part of concrete rail to W-beam rail.

Features & Benefits:

• Stronger than W-beam guardrail;

• Less maintenance after installation;

• No offset block needed.
