Interior floor expansion joint covers with a flush architectural finish
The Genotek interior floor range is the deepest in the catalogue: 43 aluminium expansion joint cover systems for gaps from 10 mm to 500 mm, spanning thermal, settlement and full seismic movement. Recessed pan systems accept tile, stone or screed so the joint reads as a narrow shadow line in the finished floor; surface-mounted plates suit retrofit and back-of-house areas where speed matters more than looks.
Load options run from pedestrian traffic in offices and hotels up to trolley duty in malls and hospitals. Every profile comes with matching wall transitions and corner units so the joint line stays continuous through the building, and aluminium construction keeps covers light, corrosion-resistant and easy to cut on site. Send us your joint widths and finish build-ups and we will confirm blockout sizes and recess depths before you pour.
