About Leagrid

Beijing Leagrid Technology Co., Ltd. was founded in 2019 and is headquartered in Beijing. Its engineering team draws on experience from established industrial networking and automation companies, and the business covers R&D, manufacturing and sales of industrial communication products.

Under licence from RUGGEDCOM (Canada), Leagrid manufactures industrial switch series built on RUGGEDCOM core technology and is permitted to carry the RUGGEDCOM INSIDE mark on the product nameplate. RUGGEDCOM builds high-performance networking and communication equipment for harsh industrial environments and was acquired globally by Siemens in 2012.

Building on that technology, Leagrid invests in domestically developed industrial communication products, covering industrial Ethernet switches, gateways and media converters, with custom development and OEM / ODM services available.

The company provides technical support across design, consulting and implementation, building secure, highly available and open industrial networks for smart infrastructure, smart grid and smart oilfield applications, as well as process control and factory automation. All products carry a five-year limited warranty.

Product direction covers industrial switching, protocol gateways and wireless access, selected against site conditions such as wide temperature, interference and long-term continuous operation.

Reusable configuration practices for ring redundancy, VLAN isolation, power and grounding shorten on-site commissioning.
