Semi-framed stainless steel and glass balustrade

Mirror Polished Vs Satin Brushed Stainless Steel Components for Exterior Balustrades

Posted on: 9th May, 2017

Exterior balustrades have become increasingly popular in modern architecture. They provide an essential safety feature for the increasing numbers of people who want to enjoy their outdoor spaces more, whether this be for dining, socialising, relaxing, or spending much valued family time.

Stainless steel and glass exterior balustrades not only provide a safety solution but also add an elegant and sophisticated finishing touch to any garden, patio, or terrace.  The functional benefit of safety combined with visual  aesthetics that add to the beauty of any building make stainless steel and glass exterior balustrades a worthwhile investment.  Outdoor living is often considered a top design priority for buyers and agents within the property market so there may be increased interest in your property and higher valuations at a time you do want to sell.  However, it is important that you choose the correct stainless steel finish for your own requirements and the environment where the balustrade will be installed.  Here we will discuss the similarities and differences between mirror polished and satin brushed stainless steel finishes to help you choose the best possible design for your balustrade.

The differences between mirror polished and satin brushed stainless steel

An important note to make is the type of finish you choose does not affect the grade of stainless steel.  Most of our exterior balustrades are manufactured using superior grade 316 stainless steel making them suitable for external use.  Our Mini-Post frameless glass balustrades offer further corrosion resistance, especially in coastal locations since they are manufactured with Marine Grade 2205 Duplex stainless steel.  However, there are differences in the manufacturing processes that create satin and mirror polished finishes which not only produce your preferred look, but also make one or the other more suitable for other considerations.  This will be discussed further below.

The manufacturing process of satin and mirror polished stainless steel

The satin finish is achieved by sanding the stainless steel in one direction using a grit belt followed by a softening and buffing process which creates a less shiny but glossy look.  Some consider this to be more suited to architectural projects where overall look is the most important factor as any wear and tear may not be as visible and many people prefer not to have too much reflectiveness.  However, it is important to realise that some level of variation should be expected with a satin finish due to the manufacturing process which also makes a satin finish more susceptible to corrosion in coastal locations due to salt particles in the air.  High humidity areas such as around swimming pools are also not suited to satin finish stainless steel and glass exterior balustrades because the grooves of the finish present increased risk of rust.

If exterior balustrades are required in a coastal location or high chloride area, we recommend our Marine Grade 2205 duplex Mini-Post frameless balustrade system.  However, if a framed design is preferred, our mirror polished Marine Grade 316 stainless steel balustrade components would also provide superior corrosion resistance.  Stainless steel and glass exterior balustrades with a mirror polished finish have a finer brushing and longer buffing process in manufacturing whereby a highly reflective surface is created.  Whilst this shiny surface is undesirable by some, it is of main aesthetic appeal to others.  Furthermore, the smoother finish enables easier maintenance and cleaning as there are no tiny crevices where dirt can become trapped.

To sum up, your choice in a satin or mirror polished finish for your stainless steel and glass exterior balustrade will depend on your personal preferences and individual circumstances for installation.  Despite this, the several benefits of using stainless steel in your design will remain the same either way.
