Material Guide

Outdoor Grade 316 Stainless Steel – Stain Polish

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments.

There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required.

We recommend Internal grade 304 Stainless Steel Tube for indoor applications, or if less than 5km from the shore we recommend a Mirror Polished Tube finish to prevent salt grain ingress and staining.

 

Types of Stainless Steel Grades

300 Series—The most widely used austenite steel is the 304, also known as 18/8 for its composition of 18% chromium and 8% nickel. 304 may be referred to as A2 stainless (not to be confused with A2 grade steel, also named Tool steel, a steel). The second most common austenite steel is the 316 grade, also called marine grade stainless, used primarily for its increased resistance to corrosion. A typical composition of 18% chromium and 10% nickel, commonly known as 18/10 stainless, is often used in cutlery and high quality cookware. 18/0 is also available.


Stainless steel finishes

Standard mill finishes can be applied to flat rolled stainless steel directly by the rollers and by mechanical abrasives. Steel is first rolled to size and thickness and then annealed to change the properties of the final material. Any oxidation that forms on the surface (mill scale) is removed by pickling, and a passivation layer is created on the surface. A final finish can then be applied to achieve the desired aesthetic appearance. Glass Clamps are available in the following finishes:

Satin finish – a fine grain effect
Mirror finish –a highly polished finish

Q. What is the difference between Internal and External grades Stainless Steel?

Answer:

The most widely used stainless steel for railing is the 304 Indoor Grade, also known as 18/8 for its composition of 18% chromium and 8% nickel. 304 may be referred to as A2 stainless (not to be confused with A2 grade steel, also named Tool steel, a steel).

The second most used stainless steel for railing is the 316 Outdoor Grade, also called Marine Grade stainless, used primarily for its increased resistance to corrosion. A typical composition of 18% chromium and 10% nickel, commonly known as 18/10 stainless, is often used in cutlery and high quality cookware.

 

Q. What is 316 marine grade Stainless Steel?

Answer:

316 Marine grade stainless is a stainless steel preferred for use in marine environments to avoid pitting corrosion. The AISI number grade is 316 and refers to the chromium content. 316 grade contains 16% chromium, 10% nickel and 2% molybdenum. The "moly" is added to help resist corrosion to chlorides (like sea water and pool chlorine).

The salts in sea and pool water acts as a catalyst to the rusting process, therefore a higher quality stainless steel should be used in areas that will be repeatedly exposed to such conditions.

While 316 marine grade stainless steel is not completely rust-proof, the alloy is more resistant than household stainless steels, and therefore more durable.

Due to the highly corrosive environment found around pools and wet areas, all Elite Balustrade Systems Fittings products are made of the highest quality 316 marine grade stainless steel to ensure years of maintenance free performance [Click here for details of care and maintainance of Stainless Steel balustrades]

Provided the grade of Stainless Steel and the surface finish are correctly selected, and cleaning schedules are carried out on a regular basis, good performance and long service life will result.


Q. What is tea staining?

Answer:

Tea staining is discolouration of the surface of stainless steel due to corrosion. It is purely a cosmetic issue that has no affect on the structural integrity or the lifetime of the material. Tea staining occurs most commonly within about five kilometres of the surf and becomes progressively worse closer to the marine source.

However, wind exposure, pollution levels, local sheltering and higher temperatures can create environments where tea staining might occur 20 kilometres or more from the coast. The effect is much less severe around sheltered bays. These same factors also increase corrosion rates of alternative materials.

Lower grade stainless steel is far more susceptible to the issue of tea staining when used in harsh environmental conditions. To minimise problems, always ensure that stainless steel used in and around swimming pools and wet areas are no less than 316 marine grade.

Elite Balustrade Systems stainless steel fixtures and fittings for glass fencing are the highest quality 316 marine grade stainless steel and are guaranteed to give you years of trouble free performance. [Click here for details of care and maintainance of Stainless Steel balustrades]

 

Q. How do I remove stains from stainless steel?

Answer:

People are often surprised to discover that although stainless steel can in fact be stained. Although sometimes tricky, stains can however be removed. When stains occur, our best advice is to start with the basics to clean the surfaces.

Elite Balustrade Systems sell a cleaning and maintenance kits for Stainless Steel and Glass. These can be found by Clicking Here.

  

Q. Why should I use Stainless Steel fittings?

Answer:

In coastal regions, sea salt carried in the air and harsh chlorine salts in pool water can damage inferior steel or plastic fittings. Elite Balustrade Systems use only 316 marine grade stainless steel in these areas, which is extremely durable and hard wearing and resistant to salt and mineral damage as well being impervious to UV. If maintained correctly, it will last a lifetime. [Click here for details of care and maintainance of Stainless Steel balustrades]

 

Q. Does Stainless Steel need any special care?

Answer:

All Elite Balustrade Systems Stainless Steel Tube products are made with the highest quality 304 and 316 grade stainless steel. In general, maintenance requires nothing more than a wipe with a damp soft cloth to remove any corrosive build up from the surface such as salts and pollution. Never use an abrasive cleaner or any cleaner that contains chlorine or bleach.
