Expansion joints refer to the gaps created during the initial design of a building when it is vertically divided into several separate sections due to factors such as temperature changes, uneven ground settlement, or earthquakes, causing the building's length to exceed the specified limit, or its planar shape to become irregular, or there to be significant differences in height. These gaps allow each section to deform independently, thereby keeping the building's vertical sections separate. Here, we showcase the ground cover expansion joints produced by Duoxin Expansion Joint Manufacturer.
