Since 2019, Marsh Alliance has proudly supplied Darling Downs Tarpaulins (DDT) with high-performance trace springs—a crucial component used in the construction of large-scale cattle shading systems across Queensland.
Based in Charlton, on the outskirts of Toowoomba, DDT is a proudly family-owned Australian business that has been designing and manufacturing high-quality tarpaulins, shade cloths, and protective covers since 1983. With a strong focus on agriculture, horticulture, and construction, DDT is known for producing weather-resistant solutions using premium Australian-made materials tailored to specific site needs.
Tackling Queensland’s Harsh Climate Head-On
DDT builds custom cattle shade structures to provide critical relief to livestock exposed to extreme heat. These large-scale solutions span thousands of square metres and are installed over paddocks where cattle graze. To ensure the integrity and longevity of these structures, a reliable, industrial-grade tensioning system is essential.
That’s where Marsh Alliance comes in.
We supply DDT with heavy-duty trace springs made from hard drawn galvanised spring wire. These springs are specifically designed to withstand corrosive elements such as heat, humidity, dust, and ammonia—conditions that are typical of Queensland’s livestock environments.
The Role of Trace Springs in Shade Structures
Though they may seem like a small component, trace springs play a vital role in the performance and durability of any shade cloth or tensioned fabric installation. Their function is to:
- Maintain constant tension despite expansion, contraction, or external movement
- Absorb shock and vibration from wind and environmental factors
- Prevent structural strain on mounting points and fasteners
- Extend the overall service life of the shading system
While trace springs are commonly used in tents, boat covers, pool enclosures, and awnings, the custom-built units supplied to DDT are made for high-load, high-exposure outdoor agricultural use.
Engineered for Endurance
The trace springs produced by Marsh Alliance are constructed from hard drawn galvanised spring wire, selected for its strength and exceptional resistance to corrosion. In the harsh outdoor conditions found across Queensland properties, this durability ensures that shade systems remain functional and safe for as long as possible, reducing the need for premature replacements or costly maintenance.
DDT on Working with Marsh Alliance
“We have been using Marsh Alliance as our sole supplier of heavy-duty trace springs for many years. Their products are superior in quality, and we can count on them to deliver on time. Our cattle shades are erected in a particularly hostile environment for products – with the heat, humidity, dust and ammonia creating a corrosive atmosphere – so we need an industrial-grade product to survive as long as possible.”
Building Stronger Agricultural Solutions Together
The partnership between Marsh Alliance and DDT exemplifies the impact that high-quality Australian manufacturing and dependable supply chains can have on agricultural outcomes.
Our ability to design and deliver precision-engineered components has enabled DDT to continue building shade systems that enhance livestock welfare, improve productivity, and withstand some of the harshest conditions in the country.
Together, we’re helping ensure Queensland livestock stay protected, and that the structures built to serve them are up to the task.
If your project requires durable, precision-engineered spring solutions built to withstand tough environments, Marsh Alliance is here to help. With extensive experience in custom manufacturing and a commitment to quality, we design and supply springs tailored to your exact specifications.
