Kingsford Smith Drive: Stainless for the long run
Brisbane’s Kingsford Smith Drive upgrade saw Australia’s largest use of stainless steel reinforcement bar to date, transforming the structural performance of one of the city’s busiest roads.  

An initiative of Brisbane City Council and designed and constructed by Lendlease, the Kingsford Smith Drive upgrade involved widening the 7km road from four to six lanes between Theodore Street at Eagle Farm and Cooksley Street at Hamilton. This was achieved via a retaining wall built between 10m to 15m out into the Brisbane River. As a major road corridor, Kingsford Smith Drive links the Brisbane CBD to Brisbane Airport, the Port of

The spirit of the Anzacs is evoked in a new architecturally stunning, stainless steel walkway that unfolds around Newcastle’s cliffs and links Strzelecki Lookout to Bar Beach.

 The much-anticipated Newcastle Memorial Walk opened on 24 April 2015 on the eve of the Anzac centenary, and features spectacular 360-degree views of Newcastle city and coastline.

The 450m raised walkway forms part of Newcastle City Council’s ‘Bathers Way Project’, a $29 million foreshore development and revitalisation program to link Merewether Beach with Nobby Beach via a coastal walk. The total cost of the walkway was $4.5 million, $3 million of which was

Stainless Steel in Western Australia Subsea Applications

Stainless Steel in Western Australia Subsea Applications

Stainless steel is the material of choice for subsea hydraulic and control line applications because of its excellent corrosion resistance, material strength benefits and weldability.

 Subsea production in the oil and gas industry involves offshore, in situ equipment to facilitate the exploration, development, production and transportation of energy reserves from underwater fields. It is a viable form of oil and gas production, providing economic, productivity and environmental benefits.

Perth-based ASSDA Member and Accredited Fabricator Diverse Welding Services (DWS) recently completed detailed design and fabrication works on two major subsea projects operated by multinational oil and gas exploration and production companies.

Riverwalk Reborn

Riverwalk Reborn

Brisbane's New Farm Riverwalk is one of the city's beloved icons. Originally constructed in 2003, the Riverwalk was used daily by over 3000 cyclists, pedestrians and runners before it was washed away during the 2011 floods.

After a construction period of nearly 18 months, Brisbane City Council’s re-imagined New Farm Riverwalk has now opened to the public, connecting New Farm to the Brisbane City via the Howard Smith Wharf Precinct.

Engineered by Arup, the Riverwalk has a design life of 100 years and sits 3.4m above mean sea level on robust piles.

Critical to its design and life expectancy is

Grade 316 - the 'first step up'

Grade 316 - the 'first step up'

If a job requires greater corrosion resistance than grade 304 can provide, grade 316 is the 'next step up'. Grade 316 has virtually the same mechanical, physical and fabrication characteristics as 304 with better corrosion resistance, particularly to pitting corrosion in chloride environments.

Grade 316 (U NS S31600) is the second most popular grade accounting for about 20% of all stainless steel produced.

This article follows on from "304 -the place to start" in Issue 10 which is also available on ASSDA's website at www.assda.asn.au

Stainless Strengthens Walls

Stainless Strengthens Walls

The devastation of the 1989 Newcastle earthquake resulted in a revision of standards specifying building materials and products to be used in differing environments. 

One of the products that came under close scrutiny was wall ties (also known as brick ties).

Assessment of the damage after the earthquake found that many walls had 'peeled away' from building structures due to deteriorated wall ties.

A wall tie connects masonry to the structural backing which supports the wall. The most common wall ties are manufactured out of galvanised steel.

Australian Standard AS 3700 - 1998 revised the conditions under which wall ties

Duplex 2205 used for United Nations Navy Recompression Chambers

Duplex 2205 used for United Nations Navy Recompression Chambers

When the United States Navy required 35 lightweight transportable recompression chambers in the late 1980s, Cowan Manufacturing took up the challenge of developing the units. 

Cowan Manufacturing developed a prototype out of a virtually unknown material. It was duplex 2205 (UNS 31803) stainless steel.

No other manufacturer in the world was producing chambers out of 2205 and, after six years of negotiations, Cowan was sourced as the sole supplier of the chambers.

Cowan chose 2205 for its high strength, light weight and corrosion resistant properties. This enabled them to meet the Navy's requirements without the weight and corrosion problems of

Council Impresses With Stainless

Council Impresses With Stainless

When the Gold Coast City Council was seeking a stable and visually stunning medium for use on their Kirra Point board walk project, they looked no further than stainless steel!

Geoff Clemence, Design Coordinator, said Council engineers chose stainless steel for the upright posts and moveable hand rail system for safety, corrosion resistance and aesthetic reasons.

"Stainless is far superior to wooden handrails in terms of safety and lasting life and will require far less maintenance," Mr Clemence said.

"From an aesthetic point of view, the stainless steel fits in beautifully with both the concrete pavement and the timber board

Stainless Strength for Bridge Projects

Stainless Strength for Bridge Projects

The Tasmanian Government has embarked on a series of bridge renewal projects, using stainless steel reinforced pre-cast concrete to replace old timber structures.

The Barnes Creek bridge is the first of three to be rebuilt on Brunie Island, south of Hobart. It utilised 7.5 tonnes of grade 316 and duplex 2205 stainless reinforcing bar in a size range of 12 to 25mm supplied by ASSDA member Arminox Australia Pty Ltd.

The Tasmanian Department of Infrastructure, Energy and Resources specified stainless steel for the reinforcing to save on ongoing maintenance costs. The location of the bridge presents construction and maintenance challenges,

The superior strength of stainless steel has long made it the material of choice for prison toilet facilities. Innovative styling has now opened up a new market in public restrooms. Increasingly, venues are turning to stainless steel to make their facilities safer and reduce costs in the long term. 

Vandalism in public facilities is a widespread occurrence, with some pub and club owners forced to replace a toilet every few weeks. While the initial outlay may be higher for stainless fittings, the cost of replacing and installing a ceramic pan can be recouped after just one instance of vandalism. Unbreakable

Walking on Water

Pedestrians using Brisbane’s scenic RiverWalk when it opens next March will be strolling across 150 tonnes of stainless steel reinforcing, embedded in 287 concrete pontoons linked to form an 875 metre long walkway from the CBD along the river to New Farm Park.

Although the 5.4 metre wide walkway will feel like a single solid structure, it is actually made up of a series of 13.5 tonne concrete blocks, half of their bulk floating below the water level.

Stainless steel balustrades will preserve open views across to Southbank and back to the CBD while ensuring public safety. These combine subtly

Stainless Braves the Elements

Stainless Braves the Elements

Advanced engineering solutions are required to handle conditions found on offshore drilling and processing platforms. The saltwater environment is highly corrosive, the flare presents extremes of temperature and the force of winds and currents is constant. The most durable and reliable materials need to be employed, which is why stainless steel plays and important part.

An impressive project making use of stainless' strength and corrosion-resistance is the Bayu Undan Gas Project in the Timor Sea, 5OOkm north of Darwin (pictured). Here, stainless steel is used to line the 18" pipelines between the processing platform and the wellhead platform 8km distant
