Aluminium Door Thresholds

Our aluminium door threshold strips — also called door bars or threshold bars — create a hard-wearing, low-profile transition between two floors and cover the expansion gap at a doorway. Anodised aluminium outlasts plastic in high-traffic areas, so these strips suit doorways, hallways, kitchens and shop entrances. The range runs from slim 30mm strips up to wide 100mm threshold strips, in 1m and 2m lengths, with screw-fix, self-adhesive and push-in fittings.

Which aluminium threshold should I choose?

Fitting an aluminium door threshold strip

Measure the doorway and cut the strip to length with a hacksaw or mitre saw, then de-burr the cut edge. For a screw-fix bar, mark and drill the fixing holes, then screw down. For a self-adhesive door bar, clean and dry the floor, peel the backing and press firmly along the full length. Ramp strips are laid with the slope running from the higher floor down to the lower one.

Frequently asked questions

What widths of aluminium door threshold strip are available?
From 30mm up to a 100mm wide threshold strip, plus 13–26mm T-bars, in 0.9m, 1m, 1.86m and 2m lengths.

Do you sell 2 metre aluminium threshold strips?
Yes. Many widths are available in a 2m (2 metre) length as well as 1m, so you can cover wider or double doorways in one piece.

What is the difference between a door threshold and a door bar?
They are the same thing — "door bar", "threshold bar" and "door threshold strip" all describe the metal strip that joins and finishes two floors at a doorway.

Can aluminium door thresholds be fitted without screws?
Yes. Many strips have a self-adhesive backing, alongside screw-fix and push-in options, so you can avoid drilling into tiles or underfloor heating.

Which threshold suits uneven floor heights?
A ramp strip, which slopes gently from one floor level to the other for a safe, trip-free transition.

How do I cut a threshold strip to size?
Measure the opening, then cut with a hacksaw or fine-tooth saw and smooth the cut end. Aluminium cuts cleanly and easily.
