Guard Rails

Sorry, we couldn't find any products matching selected filters, please try another selection.

Guardrail Functions

Guardrails can be used in a variety of places and for a number of purposes. They are generally used as a form of protection barrier, where they provide people with safety and separation from hazardous areas. Examples of guardrail uses include:

Situated next to roads and junctions for protection/boundary

Along staircases and outdoor steps for support/protection

Around the edge of balconies for protection

Along steep walkways for support/protection

Around play areas for protection/boundary

Outside schools for protection/boundary

The most common function for this particular type of guardrail is to provide safety for pedestrians in traffic populated areas. With so many vehicles on the road today, it is important that public pavements and highways are supplied with clear, strong divides, so that everyone can reach their destination safely. As pedestrian guardrails contain railings within their construction, drivers and pedestrians are provided with a solid barrier which does not obstruct visibility.

Styles and Structure

Depending on what you require your guardrail for, you can choose to have a guardrail which has a Sight Top or No Sight Top.

Guardrail without Sight Top is the basic choice of guardrail as it contains only infill bars.

Guardrail with Sight Top is perhaps the most popular choice of guardrail and along with infill bars; it has an additional gap in the upper part of the frame to supply a clear section for view. Infill bars can have either an in-line or staggered positioning within the guardrail structure and these will offer variations of visibility.

Guardrails are predominantly fixed by casting the vertical posts of a structure into concrete ground, although base plates may be requested instead if that is what you require. The structure is held together by bolts and is not difficult to install.

Guardrail Dimensions:

Height of frame (outer vertical posts) – 1372mm

Height of upper part of frame (with infill bars and/or sight top) – 940mm

Width of the frame (upper and lower horizontal rails) – 2000mm

Rectangular Hollow Section (RHS) of frame – 50 x 30mm

Width of Infill bars – 12mm


All of our guardrail structures are made from steel and meet BS EN ISO 1461:2009 galvanising standards. Galvanisation helps to minimise rusting of the guardrail as much as possible. We also offer a Polyester Powder Coating finish if you wish to inject colour into your guardrail; giving it a bolder appearance and a higher level of visibility. Powder coating is also very hard wearing and is able to last for a long period of time despite the effects of weathering. We can supply Powder Coating in a range of colour options.
