SiloMasters’ grain silos incorporate Magnelis® from ArcelorMittal

SiloMasters, renowned maker of agricultural storage solutions, has introduced Magnelis®, a high protection coated steel, into its grain silo range.

High-strength, high performance galvanised steel up to S450GD has always been a prerequisite for SiloMasters’ flat bottom and hopper silos. This steel, which has a high elastic limit, allows the manufacturer to reduce the weight of its silo products and accessories, which is advantageous for the logistics, assembly and handling of components, and which also extends the life of the products. Magnelis® is the natural next innovative step in performance for SiloMasters.


Introducing the Magnelis® ZM430 coating into its silo range has provided SiloMasters with the additional advantage of outstanding corrosion resistance, a self-healing effect ensuring excellent edge protection, and up to 25-year guarantees. The corrosion resistance of Magnelis® is three times better than galvanised steel, measured using outdoor tests.

Miguel-Angel Barrio, SiloMasters’ CEO comments: “extending the lifetime of our silos, especially in harsh environments, like ports, was our major objective. With Magnelis® ZM430 replacing HDG600 (Z600), together with the services of ArcelorMittal Distribución Iberia and strong technical support of ArcelorMittal Europe – Flat Products, we have a very powerful and convincing offer for our customers”.

The Magnelis® coating layer is unique in that the molten bath includes zinc, 3.5% aluminium and 3% magnesium. This compact layer acts as a barrier to corrosion, preventing the underlying steel from coming into contact with the ambient environment and giving the coating its excellent protection characteristics, even in deformed areas.

Quality is fundamental to SiloMasters’ vision to be the leading supplier of agricultural silos. Incorporating the Magnelis® metallic coating into its products will help ensure that this company can continue to innovate, offering the highest quality to its customers.

“ArcelorMittal’s accelerated tests and long exposure in real farm context have demonstrated the outstanding corrosion performance of Magnelis® for farms,” adds Miguel-Angel Barrio. “The product also meets the requirements of EC Regulation 1935/2004, so it is food safe,” he adds. “We are proud to make use of this innovative new material in our products.”
