Guardrail and Guide Rail Installation

In Ontario road work, guide rail commonly describes roadside vehicle barrier systems, while guardrail is also used broadly for vehicle or edge protection. The governing issue is the exact system shown on the approved design. Harrowgate installs the specified rail, posts, blocks, terminals, anchors, transitions, and connections as one complete assembly.

Post spacing and system geometry cannot be improvised around a conflict. Harrowgate locates utilities before installation and documents the obstruction. The road authority and designer then issue an accepted offset, foundation, spanning, transition, or system detail. We install that detail and capture the final position in project records.

Barrier height controls how the vehicle engages the rail and posts. Shoulder buildup, erosion, resurfacing, or incorrect post setting changes that relationship. Harrowgate surveys the controlling grade, installs posts and rail to the approved dimension, and rechecks height after shoulder and pavement work so the complete cross-section matches the design.

Inspection covers system type, component compatibility, line, height, offset, post spacing, embedment or foundations, blocks, splice direction, bolts, washers, anchors, terminals, transitions, connections, galvanizing condition, grading, and the clear deflection area. Harrowgate records and corrects deficiencies before requesting owner acceptance.

The road authority and designer select terminals based on the barrier system, approach conditions, speed environment, roadside geometry, test level, and available grading. Harrowgate procures and installs the approved terminal, including foundation, posts, anchors, cables, hardware, grading, and delineation interfaces. We do not substitute terminal components in the field.

Yes. Harrowgate establishes traffic and work-zone controls, removes damaged components, inspects posts and foundations, installs matching approved system parts, restores grade, and documents the repair. Impact damage often extends beyond the visibly bent rail, so posts, blocks, splices, anchors, transitions, and adjacent sections are checked before completion.

Provide plan and profile, barrier schedule, OPSD or project details, terminals, transitions, structure connections, traffic staging, utility information, grading, restoration, material requirements, and inspection criteria. Harrowgate prices the complete system and the civil work needed to install it, not only the visible length of steel rail.
