Customized Fabrication - Four-Legged Guardrail, Bridge Crash Barrier, Highway Fence, Multiple Materials

The selection of bridge guardrail types should first be based on the highway grade, considering factors such as safety, coordination, characteristics of the objects to be protected, and on-site geometric conditions to determine the collision resistance level. Then, choose the structural form based on the inherent structure, economy, construction, and maintenance. The installation methods include direct burying of posts, flange connection, and integrating the guardrail and bridge deck through tension reinforcement. Under permitted conditions, removable guardrails can be used.
