Open Stair Treads FAQs

What is a tread in stairs?

A stair tread is the horizontal part of the stair where users place their feet. In steel systems, these are typically removable and replaceable components that form part of the full stair structure

What is the difference between stair runs and treads?

There is no difference. Stair runs and treads are the horizontal sections of steps in a staircase. This is where people step.

Can I use open stair treads outside?

Yes. Open treads are well-suited to external use. The design allows water to drain away easily, and galvanised finishes provide protection against corrosion in exposed areas.

How many treads are on stairs?

They can be bolted into place using side plates with pre-drilled holes or welded directly to the stair stringer depending on the system design.

How long can stair treads be?

Any uniform combination of tread dimensions can be used in stairways at an angle to the horizontal within the permissible range.

What are the standard sizes for steel stair treads?

BM Steel supplies open stair treads in a range of widths and depths to suit standard stair frame layouts. If you need a specific size or fitting type, get in touch with our team.
