About TLG SYSTEMS
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.
Who we are
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.
Our objective is straightforward: deliver practical,
manufacturable and serviceable solutions that work correctly
on the vehicle and remain reliable in real operating conditions.
