The National Lime and Stone Company
551 Lake Cascade Parkway , Findlay, Ohio, United States

We’ve stood for quality, service, and value for over 100 years.

The National Lime and Stone Company is a privately held, family-centered company made strong by over a century of continuous operation. That’s why we're preferred by customers and are one of the largest and most trusted sources of crushed stone, sand and gravel, and mineral products in the country.

In addition to supplying products that support our nation’s infrastructure and basic industries, we produce significant quantities of specialty dolomite and calcium-based minerals for the glass and steel industries — and we're the largest supplier of dolomitic float glass stone in the nation.

While we're proud to offer some of the highest quality limestone products in the region, our greatest resource is our employees. National employees are limestone experts and, for decades, have been some of the most knowledgeable professionals in the aggregates and minerals industries. We strive to provide outstanding customer service and the technical support to ensure that our top-notch products are delivered when and where they're needed.

National is a 100% American company, founded on fair business and sound environmental practices. We strive to exceed our customers’ expectations in every way by delivering innovative, high-quality products at competitive prices.
