Datum SC, LLC is an industrial manufacturing company scaling precision off-site construction.
We manufacture OPA (One Precision Assemblies) — wall panels, floor panels, roof panels, and other engineered assemblies — built to exact tolerances in a controlled factory environment. By moving construction off the jobsite and into the factory, we deliver repeatable quality, faster build cycles, and precision that traditional on-site framing can't match.
Datum is the manufacturing partner in the CertainTeed OPA ecosystem, building assemblies for CertainTeed — North America's leading building-products brand and a Saint-Gobain company — to support developers and builders of single-family and multifamily housing.
As an AI-native manufacturer, we build on modern, technology-driven systems that make our production faster, smarter, and more precise.
Based in Greenwood, South Carolina.
