Length of life
In the use of fire doors in the length of life is undoubtedly very important, after all, the installation of fire doors is also a very complex work, if the use of life is too short is also very undesirable. Steel fire door because its face plate is galvanized steel plate is easy to be oxidized, and stainless steel fire door its composition of elements containing nickel, chromium and other elements have a very good corrosion resistance, high quality stainless steel fire door is relying on good service life in the market development is very strong.
Two, in the strength of the fight against the explosion
High praise of the stainless steel fire door in against explosion strength also is very good, and the steel fire door is the big difference is the result of the material is different, steel fire door outside is galvanized steel sheet, if the fire is easy to flow through, and stainless steel fire door inside contain elements such as nickel, chromium corrosion resistance is strong, can very good against the impact of the stream.
Three, the use of regional differences
Because the raw material that stainless steel fire door USES is more environmental protection and relatively cheap, the airtight performance that adds stainless steel fire door is good, very good application was mixed in building of all sorts of building trade residential building. Steel fire doors are well used in hospitals and other buildings.
Generally speaking, the difference between stainless steel fire door and steel fire door is also different in the effect of fire prevention, plus the reason of the first two kinds of material itself is also different in the scope of use. As a result of stainless steel fire doors in the length of service life is relatively long, in the strength of the fight against the explosion is more ideal, is also used in the use of the area in the residential building more frequently.
