Julong Holding is a Beijing-based provider of intelligent integrated solutions to institutional customers in China. The company designs, procures, installs, and integrates systems that help organizations manage and secure large, complex facilities — covering security, fire protection, parking, access control, broadcasting, surveillance, toll collection, and emergency management. Julong's customers are primarily public-sector and institutional organizations, including public universities, transportation operators, banks, and healthcare organizations. Julong wins business through direct invitation to quote or competitive tender processes. The core business — roughly 95% of revenue — is project-based engineering work, where Julong executes fixed-price contracts covering planning, design, procurement, system integration, installation, and testing. A small but recurring operation and maintenance segment provides ongoing support services for installed systems. Revenue scales with the volume and size of contracts won, and since contracts are fixed-price, cost discipline on subcontractors and equipment procurement drives margins. Customer concentration is high, with the top five customers accounting for roughly 93% of revenue, making deep institutional relationships central to the business. Julong's growth strategy focuses on cross-selling within existing relationships and pursuing new customers through competitive tendering, while also investing in proprietary software and hardware R&D — including smart building access control and lighting control systems — to reduce reliance on third-party technology.
