Protective Coatings
Specialist blasting and coating services supported by modern facilities and certified teams.
Our fully enclosed abrasive blasting and protective coating facility complements our project delivery services. Equipped with the latest technology and specially trained operators, Walz Group’s Protective Coatings division supports our project delivery teams with the latest abrasive blasting techniques and protective coating application.
Our well-appointed facility has broad capability to address complex project requirements. The paint yard is located adjacent to our fabrication facility and boasts a 60m x 20m workshop, complete with a 26m x 6m x 6m state-of-the-art blast chamber which ensures fumes are contained without harm to the environment.
Using the latest technology, Walz Group’s dedicated facility provides high pressure abrasive blasting within a fully enclosed grit chamber. We employ NACE accredited painting inspectors, and we’re Painting Contractor Certification Program (PCCP ) accredited. We’re proud of our track record of delivering high quality protective coating for all surfaces.
Walz were engaged by our client to complete necessary maintenance repairs and improvements to four 22m diameter thickener tanks, as part of their periodic API inspection requirements. The scope of work involved the replacement of corroded pipework, internal feedwells, structural repairs to the strakes, and full internal blast and paint.
Continuing our ongoing relationship, we were engaged by BMA to carry out the installation of Horizontal Belt Filter BF703 at its Goonyella mine in Central Queensland. It was our first time working back at the Goonyella mine in recent years and it was a great opportunity for our team to demonstrate our capabilities working alongside a new client team.
This work involved the urgent replacement of a heavily corroded footbridge at the Hay Point Coal Terminal. The new bridge had been fabricated, but was yet to be installed, and the existing structure was quickly deteriorating after the impact of Cyclone Ului. With high structural corrosion throughout the chords and stringers, the old bridge was not capable of withstanding a significant wind or wave event.
When the existing stacker-reclaimer stockyard machines (SR1 and SR2) at the Hay Point coal terminal started to approach the end of their life, BMA commenced the process of replacing them. With an anticipated lead time of two years for the new equipment to be manufactured and shipped to Australia, the machines needed work to be kept operational until the replacements arrived.
The Scope incorporates the fabrication and installation of new carbon steel pipelines (Bauxite Slurry line, Caustic line, CGW line) from the wharf to South Trees Island and from STI to the mainland via the causeway.
Cement Australia’s operations in Gladstone incorporate Australia’s largest cement kiln, capable of producing more than 1.6Mtpa of cement.
After working together successfully on previous projects, Wesfarmers Curragh Pty Ltd (WCPL) engaged Walz Group to support the installation of a new tailings retreat circuit to the Coal Preparation Plant 1 (CPP1) at its Blackwater mine in Queensland. We’ve worked at Curragh before and have gained a solid understanding of the mine’s operational requirements.
Formerly owned by Wesfarmers Resources, the Curragh Coal Mine (now operated by Coronado Curragh Pty Ltd) is located in Queensland’s Bowen Basin, 30km north of Blackwater. The main product from the mine is metallurgical (coking) coal for export.
The Dalby Ethanol Plant is Australia’s first grain-to-ethanol facility. Each year the plant converts nearly 200,000 tonnes of sorghum into 76 million litres of ethanol. The product remaining after ethanol distillation — known as sillage — is separated and concentrated using centrifuge and evaporation technology to form a high energy, high protein animal feed known as wet distiller’s grain. The soluble dry matter, known as syrup, is blended with the Wet Distiller’s Grain (WDG) and sold to the local animal feed market as Wet Distiller’s Grain with Solubles (WDGS).
BHP Mitsubishi Alliance (BMA) Goonyella Riverside Mine (GRM) replaced the rejects conveyor gantries and trestles as part of the Goonyella R10M Conveyor & Trestle Replacement project. This work was part of a planned upgrade to the existing R10M Conveyor required to rectify a series of identified deficiencies during a major 6 week outage.
To facilitate the acquisition of up to 50 additional Heavy Mining Equipment (HME), the BMA Saraji Mine (SRM) engaged Walz to build an extension to the existing workshop to include 4 additional Ultra-Class (UC) bays.
With stage 1 of the Wiggins Island Coal Export Terminal (WICET) completed, commissioned and fully operational in 2015, the construction barge wharf at the site was rendered redundant. After considering removal of the wharf, WICET decided it would be more beneficial to decommission and preserve the facility. This would keep the option of using it again for any further expansion works in the future.
Complete coating patch repairs on gantry stacker girders and associated structural elements from top of rail to 1m below rail level.
Quality and Compliance
Quality is at the core of our fabrication services. Our processes are governed by robust quality assurance systems, documented traceability and inspection regimes to ensure structural integrity and compliance with client and industry standards. Every spool and assembly is verified for dimensional accuracy, welding integrity and specification alignment before release.
Collaborative Delivery
We work collaboratively with clients, engineers and site personnel from design review through to fabrication and handover. This integrated approach ensures clarity of requirements, consistency in execution and responsiveness to changing project needs — giving clients confidence from workshop to site.
