Fire door fire limit has nothing to do with material
According to the fire door specifications, according to the fire resistance limit time of the different, wood fire doors and steel fire doors are divided into three fire door level, a fire door (fire resistance limit 1.5h), b fire door (fire resistance limit 1.0h) and c fire door (fire resistance limit 0.5h).
Wood fire doors and steel fire doors are better
Although say two kinds of doors can achieve standard of time of limit of certain fire resistance, but because of the reason of material, when happening fire, the combustion integrity of steel qualitative fire door, stability can be more wonderful.But under the precondition of the refractory time calculated by the hour, fire evacuation can use normally can completely meet the cost, so when choosing wooden fire door and steel fire door is more a practical use to select target, generally speaking, inside the main building is given priority to with wood fire door, steel fire door more external configuration.
