3. IMPACT BEAM REPAIR
The impact beam and bracket are necessary and important
parts in maintaining a survival space for passengers in a
side collision.
For impact beam, we use special high tensile strength
steel.
The high tensile strength steel maintains its special crystal-
line organization by heat treatment or alloy additives.
Since these parts were designed to exhibit a 100% perfor-
mance when they were in their original shape, if they are
deformed in an accident, or if the deformed parts are re-
paired and reused, they become unable to exhibit the same
performance as intended in the design.
It is necessary to replace the door assembly when impact
beam or bracket is damaged.
