ZM310 self-healing coating now available in our farm silos
The pace of technological evolution in the agricultural sector is relentless, and Prado Silos continues to lead the way by launching an updated version of the farm silo. This innovative silo is designed to offer more secure, resistant and efficient storage, with key improvements such as the use of ZM310 coating for extra protection against corrosion, while also featuring an optimised design to improve performance. As a result of the incorporation of new accessories and cutting-edge materials, the new and improved farm silo provides a longer service life, combined with better performance and more efficient storage, offering a forward-looking solution for any agricultural operation
The farm silo represents a key product for Prado Silos. Today, this fundamental tool for farmers has been updated and adapted to the constantly evolving needs of the agricultural sector. Technological developments in our industry and shifts in storage conditions are calling for more efficient, durable and resilient alternatives.
Among the main improvements in this upgraded model it is worth mentioning the incorporation of the ZM310 coating on the entire structure, including roof and cylinder. This special alloy combining zinc, aluminium and magnesium provides up to five times better protection against corrosion than traditional zinc coatings (Z600 or Z450). Thanks to this strategic modification, the renewed version of the farm silo, representing the ultimate solution for farming, guarantees structural integrity even in the harshest environments, thus reducing the risk of deterioration and extending its useful life. After all, those are the key qualities that any agricultural operator looks for when purchasing a farm silo.
On top of this, the ZM310 coating not only provides better protection for the whole storage system, but also offers higher resistance to cuts and scratches thanks to the self-healing properties of this material, as further explained in our blog. This feature allows the exposed material to generate an additional protective layer, preventing corrosion and ensuring greater safety in terms of storage. This high-density layer covers equally the complete surface of the steel, including flat and curved panels – which is particularly relevant in metal silos, characterised by corrugated and folded surfaces in reinforcements and ferrules.
The new farm silo manufactured by Prado Silos has been specially designed to achieve maximum stability with less material consumption. With an optimised structure of steel rings and reinforcing supports, the silo is lighter while maintaining the same level of resistance, making it easier to assemble and transport and thereby reducing costs without compromising safety.
When operating in a farm, it is essential that the equipment can be installed easily, and this new silo design allows for a more dynamic and efficient on-site assembly compared to other options on the market.
Each detail of this new farm silo has been designed to ensure a smooth user experience with optimised conservation of the stored material. Key features include:
- Capacities adapted to each farm: From 2.8 to 46 tonnes (4 to 70 m³), meeting the requirements of all types of farms and agricultural operations.
- Security access ladder: Compliant with EN 14122-4 standards, made of S350GD Z600 steel, with a safety cage extending up to the eaves of the silo.
- Efficient pneumatic filling: Pipe and connector system with a 110 mm STORZ coupling, enabling safe and controlled filling.
- Guillotine damper: Available both in manual and mechanical versions, allows for precise control of material flow.
- Level viewer: Located on the hopper or roof, enables quick visual inspection of the stored material.
Semi-automatic lid: Operated by cable from the base of the silo, optimises access management to the interior. - Reinforced fixation plate: Supplied with chemical anchors for stable and durable support.
- Variable hopper outlet: Available in 305 mm and 400 mm options to suit different extraction systems.
- Access door located in the hopper: Ideal for maintenance and cleaning operations, with a seal preventing the infiltration of water.
The new farm silo from Prado Silos is more than just a storage solution — it’s a step forward in agricultural efficiency. With a design that blends advanced technology, top-tier materials and structural optimisation, this state-of-the-art agricultural tool offers outstanding performance and industry-leading durability, while helping reduce maintenance and maximise return on investment.
