Assessing Your Site

Carefully Consider your Guardrail System

Some guardrails fit certain site conditions better than others and we recommend that you carefully consider which system is the most appropriate when making your selection.

View the information below or download the PDF on the right for more information on which guardrail is the most appropriate for your site.

STEP 1: ASSESS THE SITE

STEP 2: CHOOSE A SYSTEM

STEP 3: CHECK VISIBILITY

STEP 1: ASSESS THE SITE

As well as selecting a guardrail design for aesthetic reasons, it is important to consider how the chosen system will fit the proposed site. It is unlikely that any site is actually flat and that only straight runs of guardrail will be required - sites usually include hills, bends and awkward junctions around pedestrian crossings, and so on.

Guardrail may need to accommodate either inclines or a curved (or angled) kerb line, or a combination of both.

STEP 2: CHOOSE A SYSTEM

As the table below demonstrates, some guardrail systems fit certain site conditions better than others and we recommend that you carefully consider which system is the most appropriate when making your selection.

If the guardrail that you select will fit your site with ‘standard’ components only, this will shorten manufacturing lead times and generally speaking will be more cost effective. Also, spare components can be held in stock for replacement purposes at immediate notice rather than made to order - minimising inconvenience and vastly reducing maintenance costs. For a guardrail that requires special components, i.e. those denoted as ‘options’ in the table below, the opposite may apply.

KEY / EXPLANATION

STANDARD

These are common components, and may be held as stock items.

OPTION

These components are made to order, to precisely fit the site.

Site survey information (spot heights and relative positions of posts) is therefore required before manufacture can be commenced.

N/A

Guardrail not available in this configuration.

STEP 3: CHECK VISIBILITY

Further technical information on individual guardrail systems is available on request, including details of the maximum incline and minimum radius that can be achieved by standard components.
