KSI Supply Company History

KSI started in 1992 with KSI General Contractors by Richard and Susan and their oldest son, Scott. They began with a focus on agricultural, metal building construction and concrete work, specializing in bunker silos, feed slabs and 16′ concrete walls. Then, in 1999, the trio officially incorporated KSI Supply. Starting with just a single container load of plastic the three worked hard to serve famers on their forage needs from start to finish.

Today, KSI Supply is RKW HYPLAST’s second largest agricultural plastic distributor in the world – serving customers all over the United States and Canada. We have exclusive access to key products that will save our customers time and money and bring added value to their forage. We pride ourselves in our service and keep a large variety of all of our inventory on hand for last minute needs. We have our own delivery trucks and do our very best to deliver product exactly when you need it at a reasonable price. At KSI we value all of our customers, no matter their size, and want to earn their business season after season by proving the superior quality of our products and service.
