As well as offering advice on building and planning regulations, qw can also talk you through your design ideas as well as the many glass balcony installation options available to you.


There are hundreds of grades of stainless steel available on the market, the majority of them for specialised applications i.e. nuclear, hygenic, extreme conditions, and oil exploration.

The two main grades that are used in balcony/ balustrading and general steel fabrications are T304 and T316 (Marine quality). Type 304 – A general grade used in catering equipment manufacturing, indoor balustrading, and fabrications where corrosion resistance is not the main criteria. This material will not physically degrade(rot away) however its surface will physically discolour in saltwater or coastal environments.

Type 316 – As above but has a higher chromium and nickel content thus giving it much better corrosion resistance in saltwater environments. This is predominantly the grade Tecmet use for the majority of external fabrication work.


Dull / Satin polishes – This finish gives a brushed effect to the finished fabrication. More familiar in the form of splashbacks, cooker hobs and catering equipment. This finish is suitable for any indoor fabrication work, and for external fabrication work provided it is not in a coastal environment(within 30miles from the sea). It can discolour in a short period of time. This discolouration can be treated to restore the original finish – done manually – which then negates the ‘maintenance-free’ aspect of stainless steel.

Bright / Mirror polished – This finish is similar to chrome in appearance (shiny and reflective). The advantage of this finish is that it is not prone to discolouration (unlike the brushed finish) so is the most suitable for coastal environments. Note: Mirror polished stainless still requires a wipe with a cloth every now and then to retain its full lustre.
