About Us & Our Website

At Keystone Barn Supply, LLC "Keystone Barns" our goal and dedication is to help you with your barn project needs.  Even though we mostly specialize in selling modular horse sheds and barns, we also carry some other products, such as hardware, greenhouses and storges sheds.

We only work with few selected barn manufacturers that have proved themselves and have expertise to provide proper barn construction and good service.

In addition to offering different barns for sale, we can help you to locate those "hard-to-find" pole barn materials, stall materials, doors and barn hardware for your construction project.


It was back in 2001 when we sold our first Shedrow Barn on eBay.  Back then, we didn't even have registered company name or website.
We only made few hundred dollars, but liked the experience and idea of selling sheds.   About a month later, we figured, why not build a website and start selling different Amish built products?

And that's how it all started, we rushed to build a website, registered company under name "Unlimited Source Inc" and started looking for good quality products to sell.  In fact, we were one of the first few companies selling horse sheds, gazebos and many other Lancaster County Amish built products online.

Up until 2012 we tried to sell many different products on our website.   However, in 2012 we made a decision to drop most of items not related to horse barns and sheds.  So, in 2012 we decided to change our name to "Keystone Barn Supply, LLC." and consentrate more on modular barns and sheds - the product we know best.

Since 2001, our company tried to sell different kinds of Amish made product.  Below is the list of products we still sell and products we can help you to find or recommend a supplier.
