About Royal Building systems

50 years of creating the best exterior possible

For us, to build and to remodel is to advance. So every year, for the past 50, we’ve done exactly that. We’ve advanced the aesthetics, versatility, performance and breadth of our products to industry-leading levels. Along the way, we’ve become a highly responsive resource for homeowners and pros—from inspiration and ideas to installation and sales support. See where we started and how far we’ve progressed.

The broadest selection of PVC trim and mouldings profiles

Industry-changing lines like Celect® Cellular Composite Siding and Zuri® Premium Decking
