What Is a 40mm x 1800mm Threshold Strip?

A threshold strip (also known as a floor transition strip or door bar) is used to cover the joint between two flooring surfaces. These strips protect the edges of flooring materials while allowing floors to expand and contract naturally.

A 40mm threshold strip is one of the most versatile sizes available. It is wide enough to cover expansion gaps while still maintaining a clean, subtle appearance across doorways.

The 1800mm length makes these strips ideal for wider openings, hallways, or larger doorways where shorter trims may not provide full coverage.

Common uses include:

• Joining laminate flooring between rooms

• Transitioning from laminate to carpet

• Connecting vinyl flooring to tile or wood floors

• Covering expansion gaps in doorways

• Creating neat transitions between different floor levels
