A weld-free installation process has caught the attention of Victoria’s caving community.

Parks Victoria and ASSDA Member Stainless Tube Mills Fences Pty Ltd recently completed a visitor access upgrade for popular tourist sites, the Royal and Fairy Caves.

STM Fences’ patented assembly process for tubular panels allows for easy installation without the need for welding.

Ranger in charge of Buchan, Dale Calnin, said using this system meant installation wasn’t damaging to the caves’ sensitive environment. 

“The stainless steel balustrading looked fantastic and is a well presented modular system,” he said.

Mr Calnin said this process would be welcomed by the

Aussie Icon Immortalised in Stainless

A 200-year-old Australian icon has been immortalised in a new stainless steel home. The ‘Tree of Knowledge’ is cherished as the birthplace of Australia’s labour movement. It is believed that shearers gathered under the tree in 1891, striking for workers’ rights.

The $6 million timber and stainless steel memorial was officially unveiled earlier this year in Barcaldine, Queensland to house the remains of the tree following its death in 2006. ASSDA Accredited fabricator St Clair Sheetmetal supplied and installed 6.5 tonnes of mirror finished stainless steel cladding to achieve a highly reflective surface and

New Potential for Mirror Finish

A multi-award winning building design is using stainless steel to reduce its visual impact. ‘Zoo Booth’ is a small free-standing kiosk at Victoria’s Healesville Sanctuary and – thanks to its mirror finished stainless cladding – is very well camouflaged! The design concept came from Melbourne company TS1 Pty Ltd, who launched Transportable Design 1 (TS1) Pop-up Buildings in 2006.

For the unique application at Healesville, ASSDA member Stainless Sections provided grade 304, 1.2 mm stainless steel sheet, polished to a No. 8 mirror finish to reflect the organic surroundings. Stainless

stainless integral to design

A dam upgrade project in South Australia has achieved a world-first zero carbon footprint for water infrastructure and has used stainless steel as part of the unique design. The Little Para Dam upgrade incorporates a Hydroplus Fusegate System, with stainless steel fabrication carried out by ASSDA Accredited Fabricator LWA Engineering.

The Fusegates are similar to those built at Jindabyne for the Snowy Hydro in 2007, featuring a cast in-situ concrete design with stainless steel inlet wells and seal fixings in order to provide a 100 year design life and virtually no maintenance.

Strength and corrosion resistance vital

As wild fish stocks decline globally, the spotlight is increasingly being shone on humane stun and slaughter methods in the rapidly growing aquaculture industry. Stainless steel components fabricated by Pryde Fabrication (ASSDA Accredited) are an integral part of a Brisbane innovation that is leading the way internationally in a shift towards faster and more humane automated percussive stun methods.

Seafood Innovations International Group Pty Ltd has spent around 10 years developing fish harvest technology which enables fish to swim naturally until the second they are stunned, reducing stress on the fish and improving flesh quality.

Guidelines to Ensure Long Service Life

Design engineers frequently specify stainless steel in industrial piping systems and tanks for its excellent corrosion resistance. While stainless steel’s unique characteristics make it a standout leader in the durability stakes of alloys, it is not completely immune to corrosion.

Premature failures of the stainless steel can occur due to Microbiologically Influenced Corrosion (MIC). This corrosion phenomenon usually occurs when raw water used for hydrostatic pressure tests is not fully removed from the pipework and there is an extended period before commissioning of the equipment. The result is localised pitting corrosion attack from microbacterial

Stainless Technology Essential

Guaranteeing water supply in Australia is thirsty work. Western Australia’s new Southern Seawater Desalination Plant, currently under construction north of Bunbury, will help quench Perth residents and businesses with up to 100 billion litres of water a year. In such a highly-corrosive salt water environment stainless steel is a natural fit.

Sea water is pumped from the ocean and its high salinity is extremely corrosive. The desalination plant uses reverse osmosis to purify the sea water, essentially pushing it through a fine membrane at high pressure.

The first pass (first membrane) is the most corrosive environment which
