Simon Pepper, Managing Director of ASSDA Member SILA Global, provides an important update on shipping and logistics in the Australian supply chain.

To say the last few years have been unstable, uncertain, difficult, and perturbing would be an understatement. The worldwide impact and far reach of industry issues experienced remind us that we truly are a global economy, and an event on the other side of the world can severely affect the Australian supply chain. We are not out of the woods yet. 

Problems that occurred last year with freight rates, space constraints, rollovers, port closures and other delays are beginning

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

Standing the test of time

Stainless steel reinforcement (rebar) is increasingly being specified for its excellent corrosion resistance, long-term performance and economic benefits.

There are many advantages to using stainless steel rebar:

• Excellent durability, fire resistance and structural performance.
• Exceptional corrosion resistance in harsh marine environments, resisting chlorides and pitting corrosion.
• Extended service life and reduced life cycle costs.
• Minimal maintenance costs and therefore less disruption of service for refurbishment or replacement.
• Easy to cut and bend, good weldability.
• Cathodic protection is not required.
• Reduced concrete cover, minimising costs and delivering a more lightweight, higher tensile structure. Cracks are less

Stainless steel mesh has combined form and function in a patient-centred design to deliver a safe, outdoor sanctuary for recovering mental health patients.

Ancient civilisations understood the critical importance of daylight associated with human health, happiness, and wellbeing. Today, there is increased interest in green architecture, with natural light and air becoming a significant design consideration. Studies suggest that light and nature should be strongly considered when building new medical facilities, because of their positive effects on recovery.

Australian innovation driving sustainability

For over 30 years ASSDA Member Stormtech has been at the forefront of Australian innovation delivering stainless steel linear drainage solutions for the local and global architecture and design industries.

Stormtech is an Australian family business that began operations in 1989 and was established on the invention of a special drainage grate. Founder John Creighton was approached by an architect to help design a hobless shower for a wheelchair-bound client wishing to shower independently. Creative thinking and innovative engineering led to the birth of a unique stainless steel drainage design that delivered excellent surface water removal

Water quality plays a crucial role in the decontamination and reprocessing of reusable medical devices, and stainless steel has helped facilitate the standard required for their sterilisation. 

The release of AS/NZS 4187:2014 Reprocessing of reusable medical devices in health service organisations requires hospitals across Australia to comply with a range of stringent new requirements consistent with European and global standards for sterilisation processes. Its aim is to ensure reusable medical devices are adequately cleaned, disinfected and sterilised to protect patients and prevent infection.

Water quality is critical for sterile processing, and one requirement of the revised standard includes the replacement of non-compliant cleaning,

Everyone knows that stainless steel resists corrosion, but beyond that, an amazing range of half-truths and exaggerations have evolved - often misleading and sometimes simply wrong. This article examines some of the more common myths, explains why they are wrong, and more to the point, provides correct information.

MISCONCEPTION: There are only two types of stainless steel, 304 and 316. 

FACT: There are hundreds of stainless steels from high strength duplex 2205 supporting bridges, to furnace ducts of ferritic 3/5Cr12 and the high temperature 310, but the most common types are the austenitic 300 series.

Stainless steels were invented a little over

1934 marked the birth of the world’s first stainless steel passenger railcar in the United States, and today it represents over 80% of all passenger railcars in Australia. Stainless steels deliver a sustainable materials solution for the rail industry, offering excellent physical properties including formability and weldability, in addition to its high strength, durability and aesthetic appeal.

The typical lifespan of a passenger railcar is 30 to 35 years, however with a proper maintenance program, stainless steel railcars can last more than 50 years. While only requiring minimal maintenance, dirt and other surface contaminants from daily use can affect the

Stainless steel continues to be the material of choice for commercial kitchen equipment, meeting and exceeding the rigorous demands of busy food service operations.

The seaside town of Terrigal on the New South Wales’ Central Coast has welcomed a new addition to its foreshore with a scenic walkway using stainless steel.

The long-awaited Terrigal Boardwalk connects the existing pedestrian networks of the Terrigal Beach promenade and The Haven, providing a safe and accessible route around the headland. The new attraction provides social, health and economic benefits for the local community, allowing visitors and tourists to enjoy the public space and ocean front area.

The project was jointly funded by the Central Coast Council ($2.9M) and the NSW Government’s Restart NSW Regional Growth Environment and

Stainless steel is used for a wide range of structural applications including:

• Beams, columns, platforms and supports in processing plant for the water treatment, pulp and paper, nuclear, biomass, chemical, pharmaceutical, and food and beverage industries;

• Primary beams and columns, pins, barriers, railings, cable sheathing and expansion joints in bridges;

• Entrance structures, canopies, cladding and support systems for masonry;

• Security barriers, blast walls, hand railing and coastal structures. 

Case studies of a range of structural applications are available at the case studies section of  www.teamstainless.org/resources/information-center-for-stainless-steel-in-construction.

This introduction to structural design in stainless steel aims to highlight differences between the

Stainless steel lanterns now adorn the streets of Melbourne’s Chinatown, celebrating the cultural character of the longest continuous Chinese settlement in the western world.

Chinese lanterns are a symbol of Chinese culture worldwide, initially used to provide light and later adopted for religious worship, decoration and celebration. Traditionally made from silk or paper, the City of Melbourne recently evolved the Chinese hanging lanterns featured on Little Bourke Street from cloth to stainless steel.

In extensive consultation with the Chinatown Precinct Association, the City of Melbourne and GHD (Structural Engineers) reimagined the classic lantern with a detailed design that preserved the

ASSDA Member and Accredited Fabricator Southern Stainless have taken outdoor entertaining to a new level with their custom-designed and Australian made stainless steel gas fire pit.

Alfresco living is a strong part of Australian culture, and Gold Coast based Southern Stainless saw an opportunity to bring warmth and elegance to the outdoor space with the use of stainless steel. Starting the design process in 2015 and with over 18 months of research and development, a stainless steel gas fire pit was born, meeting both Australian Standards and gas regulations. 

Elegant and simplistic in its design, Australia’s harsh coastal conditions

With a striking and innovative design evoking visions of the Singapore based Helix Bridge, stainless steel has formed an integral part in creating one of Sydney’s most exciting new structures.

Commissioned by Landcom as part of the Lachlan Line Precinct development project in North West Sydney’s Macquarie Park, the yet to be officially named cyclist bridge provides visual flair, safe accessibility, and excitement to the area. In an area with typically heavy traffic congestion, the project’s promotion of reduced car dependency creates a significant positive impact to the surrounding environment.

The design is the first of its kind in Australia,

When comparing hot and cold formed stainless steel, the first question you would ask yourself is: are there any chemical differences between the two? ASSDA has previously published articles on the various surface finishes including the few hot and multiple cold finished processes, however this article concentrates on the differences. 

Since the 1970s, most stainless steel is produced by melting in an Electric Arc Furnace (EAF) and then the molten stainless steel is transferred to an Argon Oxygen Decarburisation (AOD) vessel or, less commonly, a Vacuum Oxygen Decarburisation (VOD) vessel. These processes control impurities such as carbon, sulphur, nitrogen, hydrogen

World-class processing systems demand high quality products, innovative features, and long-term yield increase, all of which have been delivered through superior workmanship, engineering, and the use of stainless steel.

ASSDA Member, INOX Australia, was engaged by a Melbourne based stock and soup manufacturer to design the integral process, fabricate, install, and commission a beef, chicken, seafood, and vegetable stock processing system. The processing system is entirely fabricated in stainless steel as it has been essential to the project design and fabrication, being the material of choice in demanding hygienic environments that involve high heat. 

Exceeding their client’s expectations, INOX

A mainstay in the processing of sewage water in water recycling applications, stainless steel once again plays a critical part in working towards a sustainable future.

Western Water Treatment Plant (WWTP), south of Werribee in Melbourne’s Western District, is a critical asset responsible for processing around half of the city’s total sewage. The process requires a massive footprint, where a series of large lagoons use anaerobic (without oxygen) and aerobic (with oxygen) bacteria to sequentially break down and clean the feed water of solids and gases. The resultant recycled water is used for multiple non-drinking purposes, including irrigation and firefighting. 

Stainless steel is playing a vital role in delivering effective bulk water intake screens for Melbourne’s water supply.

Designed and manufactured in Brisbane, ASSDA Member Aqseptence Group Australia has recently delivered one of the largest passive intake screens in the Southern Hemisphere. Having produced more than 4,000 screens for the last  50 years, this latest milestone achieved a nomination in the hotly contested Process Industries category of the 2019 ASSDA Fabricator Project of the Year Award. 

In mid-August 2019, Aqseptence Group was engaged by a joint venture of John Holland and KBR to provide design and construct services for a significant capital

When used properly, stainless steel enjoys a strong and enduring reputation for visual appeal and structural integrity in a wide range of applications and environments. But, like all materials, stainless steel may become stained or discoloured over time, impairing the overall look. This brown discolouration - tea staining - has been identified in coastal applications in Australia and overseas.

In the late 1990s, the newly formed ASSDA Technical Committee researched the reasons for the brown discolouration. ASSDA’s work, in collaboration with the International Molybdenum Association, led to guidelines published in 2001 explaining the causes and remedial techniques. The work was
