Chequer Plate Steel Stair Tread, Deep Front, 900 x 265 x 4.5mm, 50mm Up, 145mm Down

A solid chequer plate steel stair tread, 900 x 265 x 4.5mm, for staircases and fire escapes. It is one piece of 4.5mm chequer plate folded with a 50mm turn up along the back edge and a 145mm turn down at the front, so the front of each step has a deep, solid face that closes much of the open riser. It is sold as a DDA pattern tread. It goes in quickly on steel tread fixing cleats welded or bolted to the stringers. The price shown is for one tread, so count one for every step in the flight.

Why choose this tread

Nothing falls through. Solid plate keeps tools, fixings and debris from dropping to the level below, which open mesh treads cannot do. That makes it the better choice over a walkway, a doorway or any area where people pass underneath.

Raised pattern for grip. The raised chequer pattern gives boots more to bite on than flat plate, particularly in the dry. In wet, icy or oily conditions an open mesh tread drains better, so match the tread to the place it will be used.

Deep front face. The 145mm turn down gives a clear, solid face to each step and adds stiffness along the full width, so it reads as a proper step from below.

Quick to fit. It arrives folded and square, so there is no cutting, folding or site fabrication. Set the cleats level on the stringers, drop the tread on and fix it down.

Ready for your finish. Supplied as plain steel, so it can be galvanised, painted or powder coated to match the rest of the stair.

Where it is used

Fire escapes and external steel stairs, plant and mezzanine access stairs, loading dock steps, public and commercial access stairs where a deep front face is wanted, and replacing worn treads on an existing steel stair. It also makes a useful landing step or a stepped access on platforms and gantries.

Specifications

Choosing the right tread

Measure the clear width between the stringers, and allow for how your cleats sit. Then decide on the front edge: the standard 50mm turn down is the everyday choice, and the 145mm deep front is for stairs where you want a closed, solid face. Sizes and styles in this range are below.

Fitting and care

Weld or bolt a pair of cleats to the stringers for each step, level and in line, then fix the tread down through the cleats. Keep the rise and going the same on every step of the flight. Plain steel rusts outdoors, so galvanise or prime and paint it before fitting, and touch up any welds afterwards. Inspect it from time to time and keep the surface clear of moss and debris, which reduce grip.

The stair as a whole should be designed by a competent person, including its loading, rise, going and handrails. Meeting access rules depends on the whole stair, not the tread alone.
