We are capable of meeting the complex needs of our customer’s at any size agricultural operation, both production and processing.  We leverage the expertise of our highly trained and skilled workforce to complete your project on time and within budget.

Two Bins


If you’re in the market for a farm bin or a commercial-grade bin, Mercer supplies the GSI grain storage system to hold your type and level of grain production. Made of heavy-duty corrugated steel, we can design and install any combination of storage systems to meet your needs. We also offer a variety of wet holding tanks and hoppers to increase organizational efficiency while grain is being dried.


GSI manufactures the largest selection of advanced grain dryers in the industry, which is why R.W. Mercer Company has chosen to be an authorized supplier of GSI grain conditioning systems. From single-fan competitor dryers and in-bin aeration heaters to GSI’s-own patented X-STREAM™ and TopDry drying systems, Zimmerman and Farm for tower dryers, we are well-versed in implementing any grain conditioning configuration.  Efficiency in drying your grain gives you the best return on investment, and we believe that GSI equipment gives you that opportunity.


Whether you’re moving grain from harvest to conditioning or conditioning to storage, look no further than GSI’s grain handling systems. From small farms to large commercial operations, we can design and install a conveyance system to meet your needs. Bucket elevators, paddle conveyors, air systems or augers: we’ve got what it takes to move you—and your grain. Mercer is also a Lambton dealer for grain legs/pits/conveyors.
