Zhongxin Chuangwei provides a precision clock to Shandong Desheng Iron & Steel Co., Ltd.

Zhongxin Chuangwei provides a precision clock to Shandong Desheng Iron & Steel Co., Ltd.

Recently, Shandong Desheng Iron & Steel Co., Ltd. issued a request for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑92S‑OGB clock server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the clock synchronization project from Shandong Desheng Iron & Steel Co., Ltd.

Shandong Desheng Steel Co., Ltd. was established in 2012 and is a large-scale steel supplier integrating steel processing, distribution, warehousing, and sales, with annual sales exceeding 300,000 tons. The company maintains long-term strategic partnerships with leading national steel mills such as Shandong Iron & Steel, Baosteel, Wuhan Iron & Steel, Taiyuan Iron & Steel, and Shougang, and serves as an esteemed distributor for Ansteel, Baotou Steel, Hebei Iron & Steel Group, Anyang Iron & Steel, Nangang, and Wugang, among others. The company maintains a steady inventory of over 10,000 tons.

Shandong Desheng Iron & Steel Co., Ltd. conducted an in-depth evaluation of the DNTS-92S-OGB clock server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the company expressed high satisfaction with both our product quality and after-sales service, proceeding to place a successful order and put the system into operation.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9 can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides precise standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors. Installation and operation of the DNTS‑9 network time server are exceptionally straightforward: simply connect the satellite receiving antenna and link the Ethernet port to a network switch to achieve time synchronization for all devices on the network.
