What is the difference between a Category A and a Category B Stair?

A Category A small private spiral stair is intended for use by a limited number of people who are generally familiar with staircase. For example, an internal stair in a dwelling serving one room not being a living room or a kitchen, an external access stair to an office not used by the public, or spiral fire escape stairs for a small number of people.

A Category B private stair in addition to a Category A stair can also provide the main access to the upper floor of a private dwelling.

You can find out more about how our staircase kits are Building Regs compliant on our Building Regulations page.

Floor to Floor measurement:  is there any guidance on how you get this measurement?

Use a tape measure or laser measure to measure the vertical distance between finished floor levels

This is the distance from the finished floor (e.g. paved patio) to finished floor (decking/landing).  You will need this measurement before you place your order so we can send you the right spiral staircase kit for your space.

Don't forget to specify the right base plate...

Why do I need to select clockwise or anti clockwise?

This determines which way you walk up the stair and where you step on and step off it.

It may be helpful to review our Technical Layout Diagram to determine where the exit will be.

Why do I need to specify whether the base plate is above or below ground?

If the ground is stable and you want to see the base plate to the stair choose above finished floor level/ground level. If the ground is not load bearing you will need to cast a footing in concrete. This would normally be below the ground or finished floor level and infilled to hide the fixings. If cast below ground level an additional column spacer is required.

Do you provide fixings for securing the top of the stair?

When you make a spiral staircase, you will require fixings in order to secure the top of the stair.  We do not supply these as they will vary depending on what you are fixing the stairs to. 

How much do your staircase kits weigh?

This will depend on the size of stair you order but most of our staircase kits weigh between 300 and 400kg.  With the maximum weight being 400kg.

Please consult your own structural engineer to ensure your foundation is adequate.

What material are your staircase kits made from?

Our kits are fabricated in steel with a nonslip pattern to the treads.
