Post-weld base plates" for W-beam guardrails are posts that have a base plate welded to the bottom of the post column. This assembly is then used to securely anchor the guardrail system to a rigid surface like concrete using anchor bolts, rather than being driven directly into the ground.

Welded Connection: The primary feature is that the guardrail post is pre-welded to a thick steel base plate, by certified welders to ensure structural integrity. This provides a high-strength, rigid, and permanent connection between the post and the plate.

Installation Method: These systems are designed for applications where in-ground installation is not possible or a non-penetrating system is required, such as on bridge decks, concrete floors in warehouses, loading docks, or mezzanines. The base plate typically features pre-drilled holes for anchor bolts, which secure it to the mounting surface.

Materials: Both the W-beam and the post/base plate assembly are made of hot-rolled steel and hot-dip galvanized for corrosion resistance, especially in outdoor applications.
