1. The scale of the building is large and it is easy to form a three-dimensional fire. Color steel buildings are usually large in size due to their high strength, light weight and ease of construction. In the event of a fire, a large amount of flue gas heat is transmitted through various pipes and passages, and it is easy to form a three-dimensional combustion situation.
2. It is easy to cause casualties. In the event of a fire, flammable polymer materials such as foam filled in PPGI corrugated roofing sheet for sale increase the concentration of toxic and harmful gases or impurities due to incomplete combustion, and the threat to humans is gradually increasing.
