SEMEX

What SEMEX does

SEMEX, S.A. DE C.V. (Grupo Semex) is a privately held Mexican manufacturer and integrator of road traffic control and intelligent transportation systems (ITS), headquartered in Guadalupe, Nuevo León. Founded in 1961, the company operates from an industrial complex of more than 10 hectares that houses in-house manufacturing of LED and incandescent traffic signals, proprietary traffic controllers, structures, horizontal road markings and its own PEEK and RAYOLITE product lines, alongside engineering and product development functions. It complements this hardware base with five integrated ITS solutions: centralized traffic signal control, public transport priority with AVL, urban CCTV monitoring, variable message road information systems and electronic traffic violation enforcement.

The company serves primarily government and municipal customers responsible for urban traffic management and road safety, with named reference deployments in Mexico and internationally including the City of Chicago, City of New York, City of Seattle, the Government of Canada, the Government of China and the Government of Saudi Arabia. SEMEX reports that it manages over 21,500 signalized intersections across more than 12 countries spanning the Americas, Europe, Asia and Oceania, and that it maintains a domestic fleet of 260+ mobile installation units.

Revenue is generated through hardware sales of traffic signals, controllers, structures, signage and markings, supplemented by professional services covering engineering, design, installation, training and maintenance. Pricing is custom and contract-based for enterprise projects, typically on multi-year cycles, while a small e-commerce storefront (tienda.semex.com.mx) addresses standardized product purchases. The company holds ISO 9001:2015, NOM-003-SCFI and NOM-001-SCFI certifications and ITE international certification for traffic signal quality, and operates six regional offices across Mexico in addition to its corporate headquarters.
