What is the coefficient of friction of the glass filled slide plates?

What is the coefficient of friction of polish stainless steel slide plate?

The coefficient of friction of polish stainless steel slideplate is 0.1.

Stainless Steel Slide Plate

Can a steel section slide come in direct contact with a slide plate or do you always use two slide plates; where one is attached to support and the other is attached to the supported element?

The reason for the use of slide plates is to reduce thecoefficient of friction between two surfaces. So to use an unpolished steelsurface, defeats the purpose of reducing the coefficient of friction.
