It's a service center inside, but we installed a folding door to separate the work space.

In the vehicle industry, it should be manufactured differently from the normal folding door lower rail. Small cars with a minimum of 1 ton to a maximum of 10 ton pass countless times a day, so normal folding doors cannot withstand the weight of heavy vehicles, resulting in high breakage rates. Therefore, it should be designed differently from normal lower rail and constructed and used as a car center type lower rail. Using wings wider than regular lower rails, the weight of the heavy vehicle is distributed, and the wings are heavier, which makes it easier to pass, and the damage rate is significantly reduced.

Each car has a different size, so the door must be big enough to allow both small and large cars to enter. Therefore, more than 90% of the advantages of folding doors are necessary. This great sense of openness makes it more convenient than any other door and makes it easier to get through.
