Real vehicle engineering. Practical door system solutions.
TLG SYSTEMS develops door systems, control units, electric drive solutions and vehicle engineering services for buses, minibuses, midibuses and commercial passenger vehicles.
Built on real vehicle project experience
TLG SYSTEMS is an engineering and manufacturing company based in Bursa, Türkiye. Our work is focused on passenger vehicle door systems, mechanical components, electronic control solutions and complete vehicle engineering support.
Our experience has been developed through real vehicle projects, production constraints and integration challenges on different commercial vehicle platforms. This background allows us to evaluate each system not as an isolated product, but as part of the complete vehicle.
We consider the chassis, body structure, passenger layout, door position, axle loads, electrical signals, service access, manufacturing method and regulatory requirements together.
Engineering experience across different vehicle platforms
Our engineering background includes passenger vehicle projects developed around several light, medium and heavy commercial vehicle platforms.
Product development and engineering support
We support coachbuilders, vehicle body manufacturers, bus and minibus producers and vehicle converters with configurable systems developed according to project requirements.
Door Systems
Single-leaf, double-leaf and sliding door systems developed for buses, minibuses, midibuses and special passenger vehicles.
