Design safety

All of our balconies have been designed according to the standards set out in BS EN 1991-1-1 with its UK National Annex.
There are no gaps greater than 99mm in any design (as per regulations to prevent the passage of a 100mm diameter sphere where children under 5 are likely to be present).

Glass

For our frameless Hilton range of balconies and balustrades we use 17.5mm or 21.5mm laminated, toughened, heat soaked and kitemarked glass.

For all framed glass balconies and balustrades in our range, the glass is 10mm, toughened, heat soaked and kite marked.

Certificates of conformity can be obtained for every piece of glass upon request.

It is strong, has good thermal resistance, and breaks into square fragments if broken. It is used in buildings for unframed assemblies (such as balustrades), structurally-loaded applications, and any other application that would become dangerous in the event of a human impact.

Steel

All of our mild steel balconies are made from mild steel conforming to BS EN 10025. and hot-dip galvanised to ISO 1461:2009 to prevent corrosion. This is essential to avoid rust, and provided as standard at no extra cost!

Franklyn balconies and balustrades are made from marine-grade 316 stainless steel. This grade of stainless steel is corrosion resistant and is designed for outdoor usage.

It’s essential to ensure you’re outdoor railings, balconies and balustrades are galvanized or a minimum of 316 stainless steel if you want to keep them rust free and looking good for years.

We offer a 10 year rust free guarantee on all our products, however you can expect them to look great for even longer!

Fitting and Installation

Your balcony will be delivered ready to install, complete with all fittings and bolt covers. They are designed to be easy to install by a builder, or experienced handyman or DIYer.

As we are a small (but mighty!) team, we don’t currently offer a fitting service.

If you need your balcony to fit exact fixing centres – just let us know and we can calculate the correct balcony size for you!

IMPORTANT DISCLAIMER – While we do offer complimentary fixing kits which are suitable for most builds, they should not be used unless approved by your builder or structural engineer– because every wall and structure is different – C&R Direct accepts no liability for the incorrect specification of fixings.

See our Fitting Instructions for more advice.

Comprehensive fitting instructions are available for every balcony on request!

Welding

All welds are to BS EN 1011-2.2001.

Loading Guarding to be capable of resisting a horizontal force of O.74KN/m minimum applied to the handrail, as outlined in Approved Document K, to be installed by specialist contractor.

Design load on each fixing =0.6kN (unfactored working load based on 1.5m wide structural opening size).

Below you can see a loading test in our workshop, on two small platform balconies. As you can see, a load of 1 metric tonne does not take the balcony to failure.

The balcony shown is a 2m wide 300mm Bently platform, and a 1.5m wide 500mm Bently platform.
The fixings used here are 8mm x 70mm stainless steel coach screws which are supplied with our Juliet balconies.
However, for a platform balcony we recommend a using a bigger 10mm diameter threaded bar.
