Design , Engineering & Maintenance

With origins dating back to the late ‘90s, Canterbury Balustrade Ltd has supplied and installed balustrades to thousands of projects and has extensive experience in this field.

ENGINEERING

The ‘safety of the end-user’ is our number one priority. Engineering plays an integral part of balustrade design, as the product must be able to withstand the loads stipulated in the New Zealand Building Code. Product is not only designed with experienced and engineering expertise, it is also physically tested.

Producer statements are available for all our Balustrade designs and can be assembled to suit your specific project needs. 

SERVICE & SUPPORT

We believe that it is not just all about the product, but that service and support to the customers, architects, designers, councils and fabricators is also very important. We strive to make dealing with Canterbury Balustrade Ltd an enjoyable experience.

APPLICATIONS

Balustrades have been designed to suit a wide range of applications,from private residences to commercial developments, including such diverse projects as high-rise apartments, motels, retail premises, offices and municipal facilities.

MATERIALS

ALUMINIUM

The principal members of all Eclipse Vogue Balustrade systems are made from 6000 series extruded aluminium alloys, which have been selected for their strength, finish, and corrosion resistance. The suitability of aluminium as a durable metal in external environments, even when unprotected, has been confirmed by some 30 to 40 years of performance history. Aluminium also provides an excellent substrate for surface finishing systems to adhere to. Some minor items, such as end caps, are made from cast aluminium using primary billet. Fasteners are also either made from aluminium (eg.- rivets), or stainless steel for maximum durability. All fixing anchors are made from stainless steel. The use of these materials, combined with observance of the Care and Maintenance Instructions will ensure a long-lasting product.

STAINLESS STEEL

The principal members of custom fabricated balustrades are made from various options of 316 or 304 grade stainless steel material sections, these provide durability for interior or exterior use  and the option of a high shine or a brushed finish.

MILD STEEL

The principal members of custom fabricated balustrades are made from various options of mild steel material sections including ornate wrought iron styles. Various finishes are available on request to suit interior or exterior use. These include powdercoating and or painting with or without galvanic protection.

GLASS

Canterbury Balustrade Ltd provides a wide choice of glazed balustrades, which are very popular due to their minimal obstruction of view. Glass for balustrades must comply with section F2 of the New Zealand Building Code. Toughened Glass: This is called for a product specifications. It is very strong, but if broken it fragments into relatively small and harmless pieces. On very rare occasions it has been known to break either spontaneously or from a sharp blow on an unprotected edge. Laminated Glass: Laminated glass while being stronger than ordinary glass does not have the same desirable properties as Toughened glass, and is not preferred as a first choice.

SURFACE FINISHING

INTRODUCTION

One of the advantages of Aluminium as a material is that it provides an excellent substrate for surface finishing. Aluminium is therefore the preferred choice of material where coloured coatings are required. The main coating method used is “Powdercoating”. Anodizing is also available but with a much more limited choice of colour.

POWDERCOATING

Powdercoatings are applied as a powder, electrostatically charged to provide a uniform film thickness, followed by baking and final oven curing, resulting in a tough, smooth, and even coating. This process is performed in factory controlled conditions, and consistently gives a more uniform and superior finish compared to wet coating. Powdercoatings also have excellent adhesion to pretreated aluminium. The use of solvents for cleaning powdercoated surfaces should be strictly avoided.

ANODIZING

Anodizing is an induced thickening of the natural protective oxide film on the metal’s surface, and not a coating in the usual sense. The resulting film is clear, hard, extremely corrosion resistant, and capable of being coloured. Colour options are however relatively limited, with Satin (Natural aluminium colour), Medium Bronze and Dark Bronze being the main colours economically available for balustrades. Some accessories, such as cast endcaps, cannot be anodized, and must be powdercoated in a co-coordinating colour. The depth of the anodized film can be varied to suit the application. The use of abrasives for cleaning should be avoided as they can damage the anodic layer beyond repair.

CARE & MAINTENANCE

Instructions are made available to every purchaser of the Care and Maintenance of balustrades. It is important that building every owner observes these recommendations to obtain the durability required in the NZ Building Code.

Maintenance

Safety barriers shall be maintained in a structurally sound condition and, where applicable, self-closing gates and other components required for the protection of children shall be kept operable. Defects shall be remedied immediately they are apparent.

Surface Finish

While surface finishes do not last forever, observance of these instructions will maintain their appearance and significantly extend their useful life. Observance of these instructions is also required to achieve Durability performance and for surface finish warranties to be valid (where applicable). They apply to both anodized and powdercoated surfaces.

Care and Protection

Protect the balustrades at all times from contact with:

  • Wet cement or plaster, paint splashes, chemicals, solvents, stains and fertilisers. If contact does occur, remove the contaminant immediately and wash as described below.
  • Copper, brass, lead, mild steel, CCA treated timber, cement or concrete less than 1 month old, and water which has contacted any of these substances.
Cleaning

The balustrade and its fixing points must be cleaned down at least every six months. In areas where pollutants are common such as industrial or geothermal areas, and for all sites within 1 km from the sea or in any sea spray zone identified by Section 4.2 of NZS 3604:1999, cleaning must be carried out more frequently as required, but not less than every three months.
