Salt and water infiltration from the roadway above had badly damaged the tiles, leaving their backing plates so corroded they had to be removed in the 1980s.

Multiple design variations are possible but the most common example of a slide plate ( in structural applications ) has glass-filled PTFE bonded to a steel backing plate.
23.
Frangible bullets are often used by shooters engaging in close quarter combat training to avoid ricochets; targets are placed on steel backing plates that serve to completely fragment the bullet.
24.
Plastic armour was highly effective at stopping armour piercing bullets because the hard granite particles would deflect the bullet, which would then lodge between plastic armour and the steel backing plate.
25.
Backscatter will reflect particles off the backing plate of the active layer and will increase the rate; beta particle plate sources usually have a significant backscatter, whereas alpha plate sources usually have no backscatter.
26.
One of the two number plates off number E894 now serves as a backing plate to a doorknob at a staff club facility at Sentrarand Depot in Gauteng, which was built from two Class 5E1 shells.
27.
Although the construction details of the Chobham armour remain a secret, it has been described as being composed of ceramic tiles encased within a metal framework and bonded to a backing plate and several elastic layers.
28.
In addition the thin inner liner requires mechanical support to withstand the compressive loading due to the propellant's pressure; this support is usually provided by the side walls of the cooling channels and the backing plate.
29.
The backing plate can be made from steel, but, as its main function is to improve the stability and stiffness of the assemblage, aluminium is more weight-efficient in light AFVs only to be protected against light anti-tank weapons.
30.
They can also be used as the backing plate for the matrix itself, but this compromises the modularity and thus tactical adaptability of the armour system : ceramic and metal modules can then no longer be replaced independently.
