Sloanebuilt embraces Capral LocAl® lower carbon aluminium

Truck trailer and custom rigid body manufacturer Sloanebuilt has made an industry-leading move to Capral’s latest lower carbon aluminium on its new products

For more than 35 years, Sloanebuilt has been a leading manufacturer of custom rigid bodies and truck trailers for the local industry.

The 100 per cent Australian-owned family business prides itself on the design and manufacture of quality heavy vehicle trailers and its products are nationally renowned for their strength, durability and reliability.

However, with companies facing increasing pressure to prioritise decarbonisation and sustainability, Sloanebuilt’s dedicated leadership team is determined not to have the business rest on its laurels. Instead, it’s making industry-leading strides towards more sustainable aluminium trailer construction with a switch to LocAl® lower carbon aluminium from Capral.

The aluminium offers fleet owners and transport operators a cleaner and greener lower carbon option for their trailer builds.

Sloanebuilt recognises the significance of sustainable manufacturing in the transport industry and has taken proactive steps to integrate sustainability into its operations. In a major shift, the business has decided to switch 100 per cent of its aluminium purchases to Capral’s LocAl®, including extruded and rolled products used extensively in its aluminium trailer builds.

“Sloanebuilt’s commitment to supporting the Australian economy and using locally sourced materials is part of their ethos,” Capral Industrial Solutions NSW state manager Mark Murray says.

“I’m not surprised that Sloanebuilt is the first trailer manufacturer in Australia to switch to locally supplied lower carbon aluminium for its builds, making it a clear industry leader in this space.”

Capral says lightweight, strong and resilient aluminium has become an increasingly popular material for use within the transport sector. Through its innate ability to achieve payload reductions, aluminium, in particular, offers great potential for reducing carbon emissions by replacing traditional steel and cast-iron components with lightweight aluminium.

The weight of a vehicle’s body and chassis can be reduced by up to 50 per cent according to Capral, with this reduction directly translating to lower fuel consumption and carbon emissions.

The aluminium extruder says its versatility makes it a popular choice for trailer manufacturers nationwide. With aluminium energy-intensive to produce due to significant variations in the carbon emissions being generated by smelters during the production of primary aluminium, Capral says the industry may argue that some aluminium is considerably more sustainable than others.

The main contribution to the carbon emissions of aluminium comes from the electrolysis process used in aluminium smelting. According to Capral, around 60 per cent of the aluminium sector’s GHG emissions are from the production of electricity consumed during the aluminium smelting process.

The carbon emissions in primary aluminium production range from under four kg CO2e/kg Al to over 20kg CO2e/kg Al, largely dependent upon the energy sources used, with the current global average carbon emission for primary aluminium being approximately 13.9kg CO2e/kg Al.

In October 2022, Capral introduced LocAl®, a lower-carbon aluminium option available across locally extruded aluminium products. At eight kilograms of carbon emissions per kilogram of aluminium, the LocAl® Green offer has substantially lower carbon emissions than the current global average for primary aluminium.

The offer was expanded to include rolled products in November 2023, with Capral’s LocAl® aluminium plate now available. With a comprehensive lower carbon aluminium offer now open to Sloanebuilt, the business did not hesitate to make the industry-leading move to switch all of its aluminium purchases to this cleaner, greener option.

By choosing Capral’s LocAl® Green lower carbon aluminium, Sloanebuilt is demonstrating its commitment to reducing its carbon footprint while maintaining the high-quality builds it’s known for. This strategic move will allow Sloanebuilt to meet the increasing demand for sustainable transport options and set an example for the industry.

“We view this as an exciting and important move for Sloanebuilt,” Sloanebuilt managing director Fred Manaro says.

“Sloanebuilt trailers are used by some of the largest transport fleets in Australia, servicing some of the largest businesses in Australia across a wide range of industry sectors. As more and more businesses prioritise decarbonisation, the ability to offer a lower carbon option for trailer builds is becoming increasingly important.

“This is a simple change Sloanebuilt can make that has a huge impact on the total carbon emissions associated with our builds without compromising the quality, durability or performance of our trailers.”

Part of the Sloanebuilt quality commitment is that suppliers of materials and components used in Sloanebuilt trailers must pass stringent performance criteria, including durability, reliability and, increasingly, sustainability as critical factors in the team’s material selections.

In early 2023, Capral became the first Australian aluminium extruder to achieve Aluminium Stewardship Initiative Performance and Chain of Custody certifications for the extrusion, warehousing and distribution of aluminium products and services.

The certifications apply to all of Capral’s 26 facilities, composed of mills, distribution centres and trade centres, spread across every state and territory in Australia. These certifications recognise Capral’s commitment to responsible production, sourcing and management of aluminium products.

“It was great to see Capral achieve their ASI certifications,” Manaro says.

“This ticks a box for Sloanebuilt, giving us added assurance about the responsible sourcing of our aluminium.”

Sloanebuilt’s dedication to sustainability goes beyond just its choice of materials. The brand has also implemented various sustainable manufacturing practices, including energy-efficient processes, waste reduction initiatives and responsible sourcing.

By integrating sustainability into every aspect of its business, Sloanebuilt is setting a new standard for the industry and leading the way in environmentally conscious manufacturing within the Australian heavy-vehicle transport sector.
