We are North America’s largest manufacturer of building products and materials.
Imagine a company capable of providing the modern building materials needed to build a community, even the bridges and highways to get you there. You have just imagined Oldcastle®. Surprised? We are North America’s largest manufacturer of building products. Yet we do a lot more than manufacture products. We’re partnering with national accounts, design-build firms and construction professionals to simplify the way buildings happen. So why has no one done this before? Simple, no one else can. Oldcastle has the largest manufacturing footprint, the greatest product breadth, and we are not in a category that we do not lead. If you are looking to simplify the construction process—welcome to Oldcastle.
