Bridges made of concrete are going to expand and contract slightly for a number of reasons, including temperature changes, shrinkage of the concrete, settlement, and even the weight of vehicles. Bridge expansion joints are what allow the concrete to naturally expand and contract without cracking.
Metal expansion joints can withstand extreme temperatures and high pressures, making them ideal for applications in industries such as petrochemical, power generation, and heavy manufacturing
Metal bellows and expansion joints are used in heating, ventilation, and air conditioning systems to absorb thermal expansion and contraction caused by changes in temperature and pressure
Expansion joints play a crucial role in protecting the bridge from environmental forces. They allow the bridge to flex and adjust to environmental conditions
