How many clamps do I need to use?

Generally we use two clamps per sheet and approximately 1 clamp per metre. If for aesthetic reasons an extra long sheet is required we install extra clamps to it.

What length sheets do I need?

Our system was tested on 12mm glass sheets at 1200mm high and 2200mm long. We recommend this as the maximum sheet length with two clamps. Occasionally a longer sheet will be required and we install additional clamps.

Does this product comply with the Australian Standards?

The testing was carried out on the Frameless Glass Fencing System installed per the manufacturers installation instructions and in accordance with AS 1926.1 Appendix B and appendix C. The forces were applied per AS/NZS 1170.1 :2002. Table 3.3, A, B, E, C3. The Wind pressure test was carried out in excess of 1.5kpa on the above sized sheet. Accordingly when installed in accordance with the manufacturers installation instructions the system complies with the following Australian Standards. AS 1926.1 - Appendix B and C. AS 1288 - Glass in Buildings. AS 1170.2 - Minimum Design Loads on Structures. Wind Loads. In some 'windy' areas it will be necessary to reduce sheet sizes to meet those requirements.

What is the difference in the grades of Stainless Steel?

There are many grades of Stainless Steel, the majority of stainless steel items in this catalogue are either grade 304, 316 or 316L.

• GRADE 304: has good corrosion resistance and is one of the most commonly used grades of stainless steel.
• GRADE 316: Has a higher level of corrosion resistance. The grade 316 is often referred to as “marine grade”. Typical applications are boat fittings and architectural components for exposed coastal applications. The majority of products in this catalogue are grade 316
• GRADE 316L: Has similar properties to grade 316, however has an even higher level of corrosion resistance. The “L” stands for lower carbon.

What is tea staining?

Tea staining can be defined as the discolouration of the surface of stainless steel that does not affect the structural integrity or the longevity of the material. Tea staining occurs most commonly within about 5 kilometres from the surf and becomes progressively worse closer to the marine source. However, wind exposure, pollution levels and higher temperatures can create environments where tea staining might occur 20 kilometres or more from sea water. These same factors also increase corrosion rates of alternative materials.

How can I reduce the chance of tea staining?

Stainless steel is not maintenance free but maintenance friendly. When using stainless steel material outdoors you need to clean periodically, especially in aggressive environments like coastal areas or swimming pools. Washing regularly will reduce the risk of tea staining. For best results wash with soap or mild detergent and warm water followed by rinsing with clean cold water. The appearance of the surface can be improved further if the washed surface is wiped dry. There are a few products in this catalogue we recommend for maintenance and cleaning.

Can you offer any installation tips?

After installation the completed structure should be washed and inspected for imperfections or contaminants caused in the installation process. If discovered, imperfections should be cleaned off and polished with a suitable stainless polish. Hydrochloric acid, sometimes used to clean cement or mortar residues, should not be used on stainless steel as it will stain the surface and may start more serious corrosion.
