The company significantly upgraded the 32-year-old facility with state-of-the-art technology, advanced automation, larger batch capabilities and expanded production capacity to meet accelerating demand in roofing, metal building and OEM manufacturer markets.

The expansion adds a 60% overall increase from 2025 — and enables larger batch production. Sherwin-Williams says enhanced automation will also improve formulation accuracy, reduce any defects, increase consistency and strengthen the plant’s ability to meet lead-time commitments.

“Industry experts predict demand increasing across roofing and siding markets and this expansion bolsters our ability to deliver our products in less than five days, which is advantageous to our many customers,” said Drew Waldroup, Vice President of Sales for the Sherwin-Williams. “Increased capacity and automation also enhance our reliability, provide greater operational flexibility and allow us to collaborate seamlessly with other Sherwin-Williams manufacturing sites nationwide.”

The Bowling Green facility manufactures polyester coil coatings (PolyPREMIER™) designed for interior and moderate exterior applications such as lighting fixtures, appliances, garage and entry doors, and building products. These polyester systems deliver the toughness and flexibility required for reliable interior performance.

For exterior environments, the plant produces siliconized modified polyester (SMP) coatings (WeatherXL™), which offer enhanced UV resistance, gloss retention, and long-term weatherability for metal roofing, siding, agricultural buildings, and industrial panels. The expansion strengthens Sherwin-Williams ability to scale production and support growing customer demand.

Sherwin-Williams is a global leader in Coil and Extrusion Metal Coatings, serving coaters, roll formers, OEMs, and construction professionals worldwide with innovative, high-performance finishing technologies.
