When a fire occurs in a building a SHD system assures a controlled abduction of smoke and heat from start of a fire. This gives the people in the building more time to escape and increases the time the fire brigade have to extinguish the fire. The ducting used in a SHD system needs to withstand high temperature load resulting in high stresses and big expansions. Array Industries designed and manufactured the SHD ducting for the Metro Oost line (MOL) in Amsterdam. Do you have questions about SHD ducting? Call Array Industries!
