Roof Design

What is Roof?

Roof of car is aimpotant element which protects passengers, Roof block the rain wind hail and,

snow.. They also catch most of the sunlight.

The integration of structurs and components into the roof of a steel car body was first attempted in the Ford THINK,

a small electric car. The front rail of this vehicle,

the structural member which runs over the top of the doors, is designed as a visible aluminium component

the extruded aluminium profile (alloy EN AW-6060) includes the A pillar and ends at the top rear end.

The length of the beam is about 2.2 m, the profile has a hollow cross section with flanges and it is 3-dimensionally formed

the beam upper face is exposed to the atmosphere and the surface is untreated.

To make this more stronger we supports by roof rails and bows, which joined by mean of

mastic material.

Roof Rails

A main design consideration is whether the roof rail is joined to the vehicle from the inside or
from the outside of the roof. Joining from the inside enables the use of Mastic material supports.

Roof rail support for mounting from the outside the vehicle with a removable cover

easily mounted when needed.
