What Composite Technology International, Inc., does

Composite Technology International, Inc. (CTI) is a privately held, family-owned manufacturer and distributor of millwork products and door components, founded in 2000 in Sacramento, California by CEO Griff Reid and his parents. The company designs, develops, and delivers mouldings, frames, jambs, pre-hung door components, and proprietary substrates (Radiata Pine, Taeda Pine, Falcata, Java Hardwood, LVL, ProtecDoor™ composite, SuperComp™ PVC) and finishes (Vindex®) to building product manufacturers, distributors, retailers, and builders across North America, Asia-Pacific, South America, and Oceania.

CTI's operations are anchored by a diversified global manufacturing network spanning six countries — the United States (Atlanta, GA domestic facility), China, Cambodia, Malaysia, Indonesia, and Brazil — operated through a mix of wholly-owned subsidiaries and joint-venture mills, with on-site quality engineers and Statistical Process Control enforced via proprietary smartphone apps. The company has invested over $26 million in capacity outside China in the past three years and launched the Door Components division in 2024 around the proprietary Apex Door System™. Patents (SuperJambs®, Jamboo®) and proprietary substrates and finishes form the technical differentiators. Revenue is generated through one-time hardware sales of millwork and door components, with quote-based pricing under multi-year contracts and no subscription or recurring component. Distribution is direct-to-customer via regional sales representatives and an inside sales team, with CTI managing the full logistics chain from mill to customer dock using integrated ocean freight tracking and inland TMS.
