Steel Commercial Door
The door leaf of the steel commercial door and the door frame are produced using cold rolled steel sheets that have been hot dipped galvanized with a thickness of 0.8mm-1.0mm and 1.2mm-2.0mm, respectively.
The zinc layer guarantees that the steel door has good corrosion resistance and can last at least 10 years under normal use.
We can add a layer of transparent stoving varnish to the surface of galvanized steel by spraying the powder in order to improve the corrosion resistance and aesthetic effect of steel doors.
If customers have other requirements, we can also apply various decorative effects by using different colors of paint.
After the stoving varnish, the surface of the steel commercial doors can be processed with wood grain transfer printing to make it look like a natural wood door.
The interior of the security steel door is generally filled with paper honeycomb material which is environment-friendly and lightweight.
If customers have fireproof requirements for steel commercial doors, we will replace the internal filling with magnesium oxide fireproof board. After this, the fire resistant steel commercial doors can resist up to 30 mins of fire conditions. According to the needs of customers, steel commercial doors can be processed to be fire resistant for 60 mins or even 90 mins upon request.
Steel commercial doors have excellent security, anti-collision and moisture-proof properties. They are typically used for evacuation channels for pipeline wells, equipment rooms, workshops, elevator control rooms, computer rooms, hospital wards, basements, etc. Furthermore, because of their better decorative effects, steel commercial doors can be used as the exterior doors for homes and offices.
It is worth mentioning that we can pack a layer of lead plate on the outer core of steel commercial doors to prevent electromagnetic leakage, because hospital CT rooms often give off radiation. Steel commercial doors can act directly as radiation-proof doors for CT rooms.
