Supply and installation of designer glass and stainless steel balustrades

Technical Information

Selecting Glass for your balustrade

Glass is a popular medium for a balustrade because it offers good wind protection and the least obstruction to scenic views. We recommend that if the view is to be maximized, one should choose clear glass but in some cases coloured body-tint glass or acid etched glass can provide screening for privacy.

Our varied range of glass balustrades differ in thickness; from 8mm glass infill panels for pool surrounds and utilizing 15mm glass for our unique frameless style. We ensure all our toughened glass is produced with a beveled edge bright polish. Where a bright highly polished finish is required on radius corners - use of a specialist CNC edging machine enables consistently accurate profiling.
See example of bright polished glass.

Toughened Safety Glass

Sometimes incorrectly referred to as "bullet proof" glass (which it is not) or its brand name Armourplate, it complies with the SABS Standard 0137 (Code of Practice for glazing materials in buildings). Since 1993 it has been obligatory to use safety glass in structural glazing and we only prepare quotations on Toughened Grade A Safety glass.

Toughened glass is made from annealed glass via a thermal tempering process. The glass is placed onto a ceramic roller table, ocsillating through a furnace that heats it to approx. 720 °C. In a separate process the glass moves into a cooling chamber which forces air drafts upon both glass faces, rapidly cooling and 'freezing' tension into the glass.

Toughened glass offers the highest resistance to impact, making it ideal for use in balustrades.

Toughened glass has:
Greatest impact resistance - 5 X the strength of window glass - is least likely to cut.

Compliance with Regulations

All balustrades for swimming pools and swimming baths shall have a height of; not less than 1.2 meters measured from ground level and shall not contain any opening, which will permit the passage of a 100mm-diameter sphere.

We have had our Floating and Frameless style of balustrade “impact and line load” tested. As a result of that test, we will only supply a letter of certification and sandbag test results for this style of balustrade, with a top mounted wooden or grade 316 stainless steel clip-on handrail fitted to the top of the glass - as required to conform to SANS 10160-2.

The Freestanding balustrade with 12mm TSG is certified for use without a handrail under certain conditions.

Stainless Steel

Stainless steel is protected from corrosion by a thin layer of chromium oxide. Oxygen from the atmosphere combines with the chromium in the stainless steel to form a passive chromium oxide film that protects the stainless steel from further corrosion. Any contamination of the surface by dirt, or other material hinders this passivation process and traps corrosive agents, reducing the corrosion protection. Thus some form of routine cleaning is necessary to preserve the appearance and integrity of the surface.
For all applications, Clear View Balustrades only incorporates Marine Grade 316 stainless steel in all our component schedules, unless otherwise stated.

Maintainance

Stainless steels can be cleaned by many different methods, dependant on the level of exposure and the period between cleaning intervals. It actually thrives with frequent cleaning and unlike some other materials, it is impossible to 'wear out' stainless steel by excessive cleaning(when done correctly. Stainless Steel performs best when clean - cleanliness is essential for maximum resistance to corrosion.

Stainless Steel's best friends are quite simply soap, or a mild diluted detergent, or dilute ammonia in warm water; applied with a soft cloth or synthetic sponge. Rinse well, dry with a soft cloth or drip dry. Avoid using coarse abrasive powders, metallic scourers or 'silver cleaners' as they contain rubbing compounds which will remove the passive oxide layer and leave the base material exposed or contaminated. Instead, simply and gently clean using products which are indicated with the phrase 'Suitable for Stainless Steel.' For more thorough cleaning and scratch removal, tubes of Marine Shine are available from most hardware stores and unlike other rubbing compounds, the wax base will allow the surface to naturally passivate. Just be prepared for some serious elbow grease and are armed with enough cotton rags!
