Stainless Steel Mesh Catalogue

Steel & Tube Stainless are proud to introduce a range of quality stainless steel mesh and wedge wire grating systems.

This Catalogue has been created to aid in product selection, provide detailed product specifications and to assist you with the ordering process.

Our mesh is available in 304 and 316 grade Stainless Steel and can be used for:

• Balustrading • Interior Screens and Partitioning

• Exterior Facades • Awnings

• Sun Filters • Shop Fittings

• Wall Claddings • Sieves

• Walkways • Drainage Covers

There are of course many other potential uses for stainless steel mesh, so please feel free to contact us and discuss whatever your requirements may be. You really are only limited by your own imagination.

The information contained herein is subject to change without prior notice and should not be used as an infallible guide.

General Information

HOW TO ORDERShould you require further information or wish to order any of the products in this catalogue please contact your nearest Steel & Tube Stainless branch (as listed on the inside front cover).

STAINLESS STEEL COMPOSITIONStainless steel is a name given to a group of steel alloys that contain more than 10.5% Chromium.

Chromium has a high affinity for oxygen and forms a stable oxide film on the surface of stainless steel.

The film is called the “passive oxide layer’’ and forms instantaneously in ordinary atmospheres. The film is self healing and rebuilds when it has been removed. It is this film that gives stainless steel its corrosion resistance.

STAINLESS STEEL GRADESGrade 304 is made up of 18% Chromium 8% Nickel and offers good corrosion resistance. Grade 304 is the most common stainless steel grade produced and satisfies a broad demand for adequate performance at an affordable price. Whilst useful for interior applications, Grade 304 is not suitable for many marine or exterior applications.

Grade 316 is also known as Marine Grade Stainless Steel. Grade 316 has 2-3% added Molybdenum which improves its corrosion resistance. Grade 316 is particularly resistant to salt water corrosion, therefore making it ideal for most exterior applications.

CORROSION DEFINITIONWhen stainless steel is produced, the chromium forms an outer oxide layer. As long as this layer remains intact the stainless steel remains passive. Once the oxide layer begins to breakdown, the stainless steel becomes active and its corrosion resistance is reduced. Rust stain is the obvious visible evidence of corrosion activity.

STAINLESS STEEL ‘TEA STAINING’Stainless steel may suffer from a brown discolouration, or ‘tea staining’ over time. This problem mostly occurs within about five kilometres of the beachfront, and worsens closer to the source. Other environmental factors may also contribute to the problem such as wind exposure, pollution and elevated temperatures. This problem is visual impairment only, and does not affect the structural strength or life of the stainless steel product.

MAINTENANCE AND PROTECTIONWashing stainless steel can help to reduce tea staining, and should be an important project design consideration. Best results are achieved with a soap/mild detergent and warm water wash - followed by a rinse of clean cold water. See the table below for recommended cleaning frequency.

RECOMMENDED CLEANING FREQUENCY TABLEThis represents a recommended frequency for cleaning of grade 304 stainless steel under general conditions.

NB: Cleaning frequency may be less for other grades – but it depends on the surface finish and precise details of the structural design, its environment, cleaning methods and the expectation of performance.

Conveyor belt mesh is flexible enough to allow individually tailored designs to suit individual applications. The belts can be made 5 metres wide (plus) depending on the style and length required. Handling and installation techniques should also be well considered.

The wire can be round or flat and the crossing bars can be crimped (as in the illustration below) or straight.

Conveyor belt mesh is available on indent only. (Lead time approximately 8-10 weeks from placement of order)
