Why PAS 125 and the Kitemark® are so Important

Boron Steel
Much has been written about the new range of Advanced High Strength Steel being used in Modern car design.

USIBOR-BTR-Boron are all the same grade of steel, just with a different name, depending which country it comes from. It is very strong but light in weight.

This steel will be found in the new Volvo XC90, Saab, BMW E60, Porsche Cayenne, VW Toureg and many other cars.

In general it is used to provide extra strength in the sill area, B Post, chassis areas, rear cross members and as roll over bars. It is difficult to repair and certain repair methods should only be employed.

However, whichever new car you are working with now or in the future it is very likely that you will find some Boron steel somewhere.

Not only are there are many other new steels all with differing strengths, there are also many new coatings which the steel has been treated with. Coatings such as Zinc, Bonazinc, Granocoating, Aluminated sheet metals etc. This all adds to the confusion over the steels as well as the difficulty in repair.

Spotwelding repairs
The High Strength Steel ZSTE 340 being used on all European cars today is lighter than normal steel, on account of the alloys that have been added during manufacture. It is designed to be light and very strong but it must not tear or fold easily in an accident.
