Stair Treads for your staircase from Pear Stairs

Pear Stairs is a leading UK supplier and manufacture of stair parts, stairs and staircases. We specialise in all things stairs and can provide stair treads.

Depending on the style of your staircase, your stair tread will change as well. We have a wide range available in all types of style and material. We have oak and hardwood staircase treads both available from our online shop.

What is a stair tread?

What is stair tread?  

The tread is the part of the step which is trodden on while climbing or descending the staircase. The tread and the riser together make one step; a series of treads and risers connected by a string and railing make a flight of stairs.

A Tread can be as simple as ‘the bit you put your feet on’, or it can form a part of the statement your staircase makes.

What is stair tread?  

A stair tread may incorporate ‘nosing’, a decorative feature applied to the edge of the tread and protruding slightly over the riser beneath. This can be used to cover end grain (the rough line left after cutting in to shape).

What is stair tread?  

Nosing may also be applied to hide end grain on the open sides of the treads on a cut string staircase (where the edge is visible).

Different types

All of our treads are available in the standard sizes specified in the descriptions below, or can be made custom to your specifications, ensuring compatibility with your staircase design.

Standard wooden staircase tread

Wooden Tread  

A simple rectangular tread for use on straight staircase designs.

Rectangular Tread  

For ease of installation, our standard tread is manufactured with a knotch on the underside, into which the top of the riser can be slotted. This is routed to fit risers 18mm wide; the standard width for all hardwood risers.

Standard Tread  

Where plywood risers are used, standard riser width will be 9mm. In this case, the remaining space in the slot can be filled with a wedge or a second piece of chamfered 9mm ply.

Standard Tread  

We sell pre-made standard stair treads of 21mm thickness and 268mm depth (the distance from the riser to the back of the step). These can be cut to the desired depth during installation if required.
Standard stair tread is supplied in 1m boards, which can be cut to size during installation.

Glass tread

Glass tread  

Pear Stairs are able to supply glass treads, which are toughened for strength and laminated for slip resistance.

Glass tread  

Glass treads can be combined with timber stringers and a timber balustrade to stunning visual effect, or paired with one of our glass balustrades to maximise the effect of the material.

Glass tread  

For a truly modern and minimalistic look, many choose to combine glass with stainless steel components, such as these stainless steel dowel risers.

Glass tread  

A glass stair tread gives the look and feel of a ‘floating’ staircase; but despite its weightless appearance, ours meet and exceed the load-bearing capabilities required by building regulations.

In fact, toughened glass is five times stronger than normal glass, and the laminating process increases this strength further.

If you are interested in purchasing glass treads for your staircase, please speak to one of our qualified designers.
 

Winder tread

Winder Tread  

A winder tread is a triangular tread which is designed to be used on winder or curved staircases, and cut to a narrower width on one side than the other.

Combining multiple winders enables a staircase to change direction without incorporating landings; this is desirable where space is limited, or may simply be preferred aesthetically.

Winder Tread  

We sell pre-made winders with individual turns of 30°. These can be cut to size during installation if required – in this case, you will need to cut the tread widthwise (the left edge in the picture on the left hand side), maintaining the 30° angle and nosing.

Winder Tread  

To accomplish a 90° turn, three winders must be used together.

The beginning of a turn is accomplished using a single winder. Our pre-made single winders are manufactured 1.7m wide, and cut to a 615mm tread depth on the outside edge (the edge opposite the turn). The width can be altered during installation, but the depth should remain the same to preserve the angle of the turn.

Winders can also be produced in measurements custom to your requirements.

Winder Tread  

The single winder is followed by a second winder tread which is sometimes referred to as a ‘kite winder’ – this is because it is kite shaped, with four sides.

The four sides of the kite winder are necessary to enable the kite to sit at the center of a turn in the staircase; this will normally take the form of a 90° corner in the string or a wall. The two outside edges of a kite winder are therefore cut at 90° from one another, allowing it to be slotted easily into place.

Our pre-made kite winders are cut to 1.23m wide and a total 634mm tread depth on the outside edge.

Kite winder  

The third and final winder required to complete a 90° turn is a second 30° winder.

Our pre-made third winders are cut to 1.22m wide and 615mm tread depth on the outside edge.

The width of any winder tread can be altered during installation, but the depth should remain the same to preserve the angle of the turn.

Winders can also be produced in measurements custom to your requirements.

Winder Tread  

A left or right turn can be incorporated into a staircase using left or right handed winder treads; for a left turn, left handed winders should be used; for a right turn, right handed winders should be used.

Whether the tread is right or left handed determines which side of the tread is narrowest; for example, on left handed winder tread, the narrowest side would be the left hand side.

Please make sure you know whether you require left or right hand winders before ordering from us. This is to ensure that the nosing and riser slot are positioned correctly on the treads you receive – were you to simply flip a right-hand winder over, the tread would be upside down, with slot on top and nosing below.

Winder Tread  

Each of our winder treads is manufactured with a nosed edge, meaning that nosings do not need to be purchased separately.

Bullnose tread

Bullnose  

A bullnose (also called a ‘bullnose step’ or ‘starting step’) is a decorative feature that can be added to the bottom of a staircase which is open on one or both sides. (‘Open’ means that the edge of the staircase does not butt up against a wall.)

Bullnose  

This means that the first step from the bottom of the staircase may be rounded, and wider than the other steps.

Bullnose  

This isn’t just cosmetically appealing; a wider base can mean a sturdier staircase.

Bullnose tread should be used with a bullnose riser. Together, the two components form one bullnose step.

Bullnose  

We sell pre-made bullnose treads of 265mm depth and 1.05m length. These are the standard dimensions; treads can be cut to size during installation if necessary, or produced custom to your specifications.

The pre-made bullnose treads in our shop are single bullnoses, designed for staircases which are open on only one side. Before ordering bullnose tread, you’ll need to know whether you require a left-handed or right-handed bullnose.

bullnose tread  

For a staircase which is open on both sides, a double bullnose is used. This is rounded on both sides.

Because a double bullnose tread cannot be cut down to size during installation, we don’t sell pre-made double bullnose treads in our shop.

bullnose tread  

Instead, we manufacture double bullnose treads ourselves, custom to your staircase’s measurements. If you require a double bullnose, please contact a member of our staff with your staircase’s exact measurements, and we will manufacture the tread to fit, in a timber of your choice.

We are happy to produce bespoke bullnose treads to your design specifications, such as the unique six-sided step opposite.

D-end tread

D-end tread  

A D-end step (sometimes called a ‘curtail step’) is a decorative feature, similar to a bullnose, that can be added to the bottom of a staircase which is open on one or both sides.

D-end tread  

D-end tread is designed to be used with a D-end riser; together, the two components form a single D-end step.

D-end tread  

Pear Stairs supplies single and double going D-end treads.

A single going D-end step is used when only a single entry step (the first step from the ground floor) is desired, and can be used in less spacious settings for an elegant appearance.

Double going D-end tread  

A double going D-end step is used when two entry steps are desired.

The single going D-end then sits on top of the double going D-end, creating a wider, more imposing staircase entry. This is called a ‘double D-end’ or ‘double curtail’.

Double going D-end tread  

We sell double going D-end tread of 245mm tread depth and 485mm going (the total step depth, on which the single going D-end step sits). This type of tread is available either left or right handed – it is important that you know which side the D-end will be on before ordering.

Whether the D-end is left or right handed is determined by which side of the staircase butts up against the wall.

Single going D-end tread  

We sell pre-made single going D-end tread manufactured to 260mm tread depth. This can be used on either left handed or right handed D-ends.

Both single going and double going D-end treads are supplied in widths of 1.4m, which can be cut to size during installation.

D-end tread  

Where a staircase is open on both sides, a double D-end (not to be confused with a double going D-end) is used – this is rounded on both sides.

D-end tread  

As a double D-end tread cannot be cut down to size during installation, all double D-end treads must be manufactured custom to your staircase’s measurements. This means that we can’t sell double D-end treads pre-made.

If you require double D-end tread, please contact a member of our staff with your staircase’s exact measurements, and we will manufacture the tread to fit in your choice of timber.

We can also manufacture bespoke D-end steps, custom to your design specifications. Examples of D-end steps we have produced for our customers are:

D-end tread  

This extra-large double going D-end step.

D-end tread  

This bespoke square-edged double going D-end step.

Spacesaver tread

Spacesaver tread  

Spacesaver tread is used with spacesaver stairs, are also called ‘alternating tread’ stairs and ‘paddle’ stairs. This type of staircase is designed, as the name suggests, to save space!

Spacesaver tread  

The tread on a spacesaver staircase is unique in design: Part of each tread is cut away on either the left or right hand, alternately. The climber ascends and descends the stairs by placing the left foot on the left hand tread, the right foot on the right hand tread, and so on.

When ordering spacesaver stairs, most of our customers specify which side tread they prefer to start with; left, or right. This makes it much easier to grow used to climbing spacesaver stairs, as most people have a foot they favour first when climbing a staircase. Try climbing your pre-existing staircase and make note of which foot you start with.

Spacesaver tread  

Spacesaver stairs can take some getting used to, require practice, and should only be used by people who are physically fit.

It is impossible to turn around on spacesaver stairs and both feet cannot occupy one tread at the same time; this is not ideal for residential use.

Additionally, Pear Stairs only supplies spacesaver staircases in hardwood. We believe this is safest, due to the high strain placed on each of the treads when climbed.

Spacesaver tread  

Where a spacesaver staircase is used, it must comply with certain guidelines:

  • A spacesaver staircase must not be used as the sole staircase in a dwelling.
  • A spacesaver staircase must only be installed in straight flights – winders are not viable.
  • A spacesaver staircase must be installed with a handrail on one or both sides.
  • A spacesaver staircase must not be the sole route of access to more than one room, which must not be the sole WC in the dwelling.
  • A spacesaver staircase must not be the sole route of access to a habitable room; i.e., a bedroom, lounge or other room which residents access often throughout the day.
 

Pear Stairs produces spacesaver treads to a minimum thickness of 32mm, for safety. As each spacesaver staircase is produced to customer specifications, tread width may vary, but we suggest an absolute minimum width of 500mm.

Our free staircase design tool – StairCreator will be able to show what different staircases can look like with varying stair treads.
