Rather than new construction, silo refurbishment provides wear protection for the raw and construction materials industry
GrüLo COAT GmbH | Standnummer: P136
Bulk materials handling and processing subjects silos, hoppers, chutes and transfer points to high stresses. Factors such as abrasion, moisture, corrosion and mechanical wear can affect service life, material flow, operational safety and maintenance requirements.
At Steinexpo 2026, GrüloCoat GmbH will focus on refurbishing steel and concrete silos using its GrüloCoat Systems polyurea coating. Silos in quarries, gravel pits, recycling plants, concrete works and mineral processing facilities are subject to particularly high stresses. Abrasive bulk materials, moisture and corrosion can lead to erosion, caking and leaks of the material. This often raises the question: should we refurbish or build new?
GrüloCoat GmbH demonstrates that professionally carried out silo refurbishment is often a more cost-effective alternative to new construction. Replacing existing silos usually involves high investment costs, long lead times, and costs associated with dismantling and disposal, as well as production downtime. Polyurea coatings enable existing equipment to be used and extend its service life. Once the substrate has been prepared and any necessary repairs have been carried out, the coating can be applied swiftly. This allows maintenance windows to be utilised efficiently, reducing downtime and improving plant availability.
Polyurea provides impressive resistance to abrasion and corrosion, as well as elasticity and a solid, seamless finish. These properties help to reduce the build-up of bulk materials and improve material flow. Even in older plants where the walls are damaged, the coating can be used to repair them without replacing the entire structure. GrüloCoat GmbH also offers wall thickness measurements to aid decision-making, providing information on the condition of the silo.
GrüloCoat systems are not only suitable for silos, but also for tanks, hoppers, cyclones, screw conveyors and transfer points. GrüloCoat GmbH’s product and service portfolio also includes hose solutions for abrasive media and hot rubber linings for hoppers, baffle plates, chutes and slides. At Steinexpo 2026, GrüloCoat GmbH will target decision-makers, maintenance engineers, plant managers and technical managers from the mining, processing and building materials production sectors. Through direct dialogue, the company will demonstrate how plants can be effectively protected, downtime minimised, and existing systems optimised in a cost-effective manner.
