Floor & Floor-to-wall Expansion Joint Covers In Stainless Steel, Aluminium & Brass

The Latham Flat Lines Series NO BUMP expansion joint covers are specifically designed for applications where a bump in the floor can not be tolerated. These systems offer limited movement but ensure that there is no bump for beds or trolleys that pass over the cover. The systems offer thermal and structural movement and shrinkage and will accommodate limited seismic movement. Systems are available in stainless steel, aluminium, brass and various shallow cover plate inserts to complement most facets of architectural design, whilst incorporating the required movement element. Flat-Line Series floor and floor-to-wall expansion joint covers should be considered with Wall-Line Series wall and ceiling expansion joint covers.
