MAKING MASS TIMBER ACCESSIBLE

Our company was founded in 1949 and continues to operate according to the Sterling family values to this day. Since we are always innovating and adapting to our customers’ needs, we were one of the first companies to begin manufacturing CLT and offered its unique benefits to the site access and industrial matting market.

Today, Sterling is still America’s largest CLT manufacturer with the capacity to produce 1,000 panels a day at our plants in Lufkin, Texas and Phoenix, Illinois. In 2022 we expanded to bring our exceptional operational capacity and wealth of experience to the building construction market, with PRG 320-certified structural CLT panels available at competitive price points and timelines.

HOW WE DO IT

Sterling Structural makes mass timber accessible. We’re committed to bringing mass timber’s benefits to the wider AEC community to support building projects both large and small.

SUSTAINABILITY MEETS AFFORDABILITY

Since roughly 75% of the carbon sequestered in a mass timber building is stored in its floor and roof slabs, increasing the adoption of mass timber for horizontal plate applications can significantly reduce the carbon footprint of your built environment. This approach provides flexibility for the utilization of a wider range of vertical support materials while making substantial progress in sustainability.

My experience working with the staff at Sterling Structural has been exceptional. Their dedication to delivering dimensioned products as specified, on time, and within budget gave me complete confidence. Sterling’s staff and efficient manufacturing process also made it possible for our small nonprofit to use mass timber for privately funded affordable housing, marking the first development of its kind in Northern Michigan. I am very pleased with their service and continue to use them without hesitation.
