Shengjiu Group

What Shengjiu Group does

Shengjiu Group (生久集团有限公司) is a privately-held Chinese industrial hardware manufacturer founded in 1984 and headquartered at No. 1 Shengjiu Ring Road, Dayin Town, Yuyao City, Zhejiang Province. The company operates a 90,000+ square-meter integrated factory with approximately 2,000 employees and a portfolio of 300+ patents, producing two core product systems: (1) Industrial Lock Systems, comprising mechanical cabinet locks (plane, link, handle, cylindrical, panel, and latch locks), smart electronic locks (fingerprint, password, IC card, face recognition, Bluetooth BLE4.0, and 485 remote-unlock variants), and a full accessory set of hinges, handles, sealing strips, latches, and link rods; and (2) Thermal Management Systems, spanning DC axial fans, centrifugal blowers, and aluminum-brazed air-cooled, liquid-cooled, and phase-change heat sinks. Products carry certifications such as 1000-hour neutral salt spray testing for corrosion resistance and IP54 to IP67 ingress protection ratings for demanding environments.

The company monetizes through direct B2B hardware sales, serving five vertical end-markets: power supply (UPS, distribution cabinets), new energy (EV charging stations, energy storage systems), construction machinery (loaders, excavators, boom vehicles), transportation (ETC cabinets, smart street lamps, monitoring equipment), and information and communication (servers, inverters, telecom equipment). Pricing is quote-based rather than publicly listed, and the company supplements its direct-sales motion with a proprietary product-selection tool on shengjiu.com and a dedicated B2B e-commerce storefront at shop.shengjiu.com. No named end-customer logos are disclosed, and the company's own materials state sales into 100+ countries, suggesting a distributed industrial customer base rather than a few anchor accounts.

The go-to-market is sales-led with custom engineering support for thermal solutions integrated with locking hardware. No external funding rounds, M&A activity, or public ownership events are disclosed; Shengjiu Group operates as a founder-controlled private manufacturer. Vertical differentiation is achieved through application-specific solution pages and a broad accessory ecosystem, while the recent product launches (DS899-8A smart electronic locks, MS983-3-1-Y specialty-vehicle lock, HIPCU phase-change heat sink) and inclusion of "robot structural components" in the corporate tagline signal an intent to extend into connected locks, higher-value thermal technologies, and industrial-robotics parts.

Broad incumbents

• Assa Abloy: Swedish-listed global leader in locks and access solutions with substantial industrial hardware exposure. Broad incumbent with much larger scale and global brand presence that competes broadly in industrial cabinet and access hardware.
• Boyd Corporation: US-based thermal management solutions provider offering heat sinks, liquid cooling, and engineered cooling modules. Broad incumbent competing in the custom thermal solution space where Shengjiu is positioning its higher-margin offerings.
• Rittal: German manufacturer of industrial enclosures plus integrated climate control/thermal management products. Broad incumbent that overlaps with both Shengjiu's enclosure hardware and thermal businesses but serves customers primarily through complete enclosure systems.
• Delta Electronics: Taiwan-headquartered global electronics and thermal management major with large DC fan and heat sink product lines. Broader incumbent with overlapping thermal products but vastly larger scale, broader portfolio, and global brand presence.
• nVent (Hoffman): US-based manufacturer of electrical enclosures and thermal management solutions (under the Hoffman brand). Broad incumbent serving overlapping industrial OEM customers, with comparable products in cabinet hardware and enclosure cooling.

Direct peers
