Question 1

What is the difference between a utility rail and a standard handrail?

Accepted Answer

A utility rail is a plain rectangular section used as the structural top or bottom member in a balustrade frame. A shaped handrail typically has a moulded or rounded profile designed to be gripped by hand. Utility rails are used in pairs to hold spindles, with the shaped handrail sometimes fitted on top.

Question 2

Do I need to treat the cut ends of pressure treated decking rail?

Accepted Answer

Yes. Cutting exposes untreated timber below the surface. Apply an end-grain preservative or exterior wood treatment to all cut ends before fixing to maintain protection against moisture and decay.

Question 3

What length spindle spacing should I use with 38mm x 69mm balustrade rail?

Accepted Answer

UK building regulations require that gaps between balusters do not allow a 100mm sphere to pass through. For most domestic decking and stair balustrades, spindles are spaced at roughly 100mm centres, but always check the current Building Regulations Approved Document K before finalising your layout.
