Selection of materials
Despite the threat of other materials, steel sheet maintains a
prominent role.
Steel plate remains a principal material for construction of
bodywork of a car
Main characteristics of the automotive plate must be
achieved implementing steel plates, aluminum or elements of
lightweight plastic

The use of plastics for this purpose has the following
inconvenients :
Difficulty in getting a good finish, but that tends to deteriorate
over time;
Conservatism in the use of steel;
Repair harder and more expensive;
Inconsistent quality in large series particularly when molding
techniques require labor-intensive; Some plastics are not recyclable (thermosets).

Aluminium

The main thing that leads to the use of aluminum for carryingout car plates based on
the considerable reduction in vehicle weight.
But the steel compared to aluminum has additional advantages
such as; lower material cost;
lower manufacturing cost;
use existing manufacturing techniques;
better weldability; better embedding;
Better ability to be painted.

Steel

Basically, the steel is still have the following advantages:
Relatively inexpensive material;
Can be shaped plastically in complicated forms;
Can be soldered in a a single block of high rigidity; Resistance to bending and torsion;
Ability to absorb energy in a state of plastic clash;
Can get good surface finishes with coatings and paints used.
These characteristics have to do partly with the high modulusof elasticity and the characteristics of strength and ductility of
the steels used.

BODY TRIM PACKAGES
Typical elements that may be included in a trim package
include:
Special paint, some with the appearance of pearl, others
showing color variations depending upon light angle Paint patterns using multiple colorstwo-toneor three-tone
(out of current favor)
Aluminum, plastic, or Stainless Steel trim to divide paint
regions (out of current favor) Applied graphics on Printed plastic sheeting with adhesive
backing

Road safety and environmental
benefits by IAP
Pin striping, usually applied as a dealer add-on using
special plastic tape and a removable backing
Plastic Bumpers painted the same color as the vehicle
body, rather than a matte black (now mostly included inthe base level vehicle)
Plastic rub strips to reduce paint and metalwork damage
from adjacent car doors that are carelessly opened
Interior upholstery materials specific to the package;leather in whole or part is often used in high-end trim
packages

Wood-patterned plastic or applied surfaces in the interior
or exterior; applied surfaces are out of current favor as
they require careful design and application and lack
translucency
Genuine wood trim, rare but used in some high-end
applications
Exterior Vinyl proof covers, simulating the appearance of
a convertible(out of current favor)
