High-performance machinery designed to meet the rigorous safety and durability standards of South Korea's metropolitan road networks.
As one of the world's most densely populated and technologically advanced metropolises, Seoul represents a unique paradigm in urban transportation. Under the Seoul Metropolitan Government's ambitious "Smart Seoul 2030" master plan, the city is rapidly transforming its road systems to support autonomous driving, enhanced pedestrian safety, and eco-friendly infrastructure. This massive technological shift places high demands on the quality, visibility, and durability of road markings.
Seoul's roads experience severe traffic loads daily, particularly along major arteries like the Gangnam Boulevard, Olympic Expressway, and the Gyeongbu Expressway entrance corridor. Combined with South Korea's dynamic seasonal weather—characterized by sub-zero winters requiring aggressive de-icing salts, and hot, humid summer monsoons—road markings are subjected to extreme physical stress. Consequently, municipal purchasing managers and local contractors are shifting away from traditional low-durability paints toward advanced thermoplastic and high-pressure cold-spray systems.
To prevent constant maintenance disruptions in a city that operates 24/7, road painting machinery must deliver rapid application, ultra-fast curing times, and exact line precision to comply with the Korean Road Traffic Authority regulations.
The road marking industry in South Korea is undergoing a revolution driven by three major market forces:
Our company is positioned at the forefront of this evolution, delivering high-precision machinery and premium consumables that directly address these metropolitan challenges.
Our parent factory, LXD, was founded in 2003, accumulating over 20 years of solid industry experience. In 2020, we established the Heavsty factory, introducing an intelligent workshop, advanced precision lathes, and an elite research & development team. Today, we stand as the largest manufacturer in the road marking sector in China, providing comprehensive, one-stop services covering research, industrial design, high-precision production, quality inspection, and global shipment.
With a specialized service and R&D team of 40 experts and a sprawling manufacturing facility exceeding 20,000 square meters, Heavsty has secured a leading position in the traffic safety industry. We are recognized for our keen market insights and strategic layouts, offering customized solutions to municipal governments and private contractors worldwide, including the highly demanding South Korean market.
Understanding the local urban layout is key to deploying the correct machinery. Our equipment is optimized for the specific challenges presented by Seoul's road layout:
For high-traffic districts, road marking projects must be completed overnight. The HW-12L Cold-Spray Road Marking Machine is highly favored for its rapid setup and precise line margins, allowing teams to mark miles of lanes and reopen traffic within hours.
Expressways demand thick, highly reflective, and wear-resistant thermoplastic markings that can withstand high-speed heavy vehicle traffic. Our high-capacity Thermoplastic Extrusion Marking Vehicles ensure uniform material application and optimal glass bead distribution for maximum night-time retro-reflectivity.
School zones require red and yellow colored safety markings with high anti-slip properties. Our dual-use cold spray systems are ideal for applying high-friction, vibrant warning coatings that reduce braking distances and protect children.
From preliminary planning to long-term maintenance, our integrated systems ensure high efficiency and durability.
Our solutions aim to optimize municipal transportation networks, improve traffic throughput, and maximize safety. Through data-driven scientific analysis and humanized design, we help build sustainable road systems for high-density metropolitan areas like Seoul.
We provide specialized consulting on line thickness, retro-reflectivity standards, and the integration of automated lane marking technologies compatible with future autonomous driving systems.
Proven reliability in demanding environments worldwide, from international airport runways to major metropolitan expressways.
Applied successfully at Kuwait International Airport. This state-of-the-art system removes thick rubber deposits and old markings using high-pressure water jets without damaging the underlying runway asphalt. The integrated vacuum system ensures immediate drying, minimizing runway closure times.
