Last month I explained how fittings offered a more flexible and quicker solution than fabrication for the construction of handrail and guardrail systems. I’m going to continue this topic in this month’s Blog Post by looking at some typical designs, showing how easy it is to construct a barrier systems with fittings.
Best Practice in Design
When designing barriers, handrails and guardrails, systems must be designed specifically for the intended application and in line with UK regulations so that they meet the specified loadings. For example:
- 360 newtons per metre run for industrial use and non-emergency use
- 740 newtons per metre run for commercial use
- 1500 newtons per metre run for retail and public access applications
Load Table
Typical Layouts
Although there is a vast selection of fittings to choose from, in reality you really only need a small selection of different fittings in order to construct most barrier systems. The following are the most common applications using standard ‘off the shelf’ fittings:
The universal guardrailing solution
Unique 0° – 11° range for in-line construction. Non-handed fittings allow consistent alignment of grub screws.
Maximum strength, minimum installation time and cost
Complies with BS7818 clause 2.4. Each railing can be replaced individually, offering large cost savings when repairs are required
Ensuring Correct Installation
As with any system, there are some simple do’s and don’ts when using fittings in order to ensure that the barrier, handrail or guardrail is installed correctly and fit for purpose.
For example, uprights should be installed into brickwork with a standard fixing depth of 250mm deep and into a 150mm deep cored pocket for concrete applications. Once the upright is in position standard resin Part KF410 should be poured into the pocket.
NEVER bolt the system directly into brickwork and don’t use wall fixings as base fixings.
The Flexible Solution
The wide variety of fittings available means that systems can be easily constructed to meet specific applications ranging from slopes on bridge parapets and retaining walls to staircase access on the sides of motorways or railways. When it comes to barrier and guardrailing, constructing systems from fittings can save time, provide value for money and deliver and durable solutions.
