Fire-rated metal frames are specially designed steel structures intended for the installation of fire doors. Together with the door leaf, they form a certified fire barrier that helps slow the spread of fire and heat between individual spaces, contributing to the protection of people and property. Thanks to their robust steel sheet construction, they ensure high strength, stability, and long-term durability even in demanding conditions. <\/p>\n
Two basic types are available based on the installation method:<\/p>\n
One-piece fire-rated frames (Kooperativa, Chadim) \u2013 installed by walling into the rough opening during the shell construction phase. This solution ensures maximum strength and stability and is ideal for new builds or projects requiring a solid and permanent installation.
\nTwo-piece fire-rated frames (Kooperativa, Chadim) \u2013 designed for retrofitting into a finished opening. They consist of two parts that join around the wall during installation. This allows for quick and clean installation without the need for masonry work, which is particularly advantageous for renovations. <\/p>\n
The frames are standardly equipped with a seal groove, which is crucial for the correct function of the fire barrier and also improves acoustic properties. The design can include preparation for a door closer or other technical modifications according to the specific project and door type. <\/p>\n
In terms of surface finish, the frames are usually supplied with a protective primer that serves as a base for the final finish. This can be customized as required \u2013 most commonly by painting or powder coating in RAL shades. <\/p>\n
Kooperativa and Chadim fire-rated steel frames are suitable for apartment buildings, office buildings, schools, hotels, and other facilities where fire safety requirements must be met. They represent a reliable solution for projects where the emphasis is on functionality, safety, and the long service life of the entire door system. <\/p>\n","protected":false},"excerpt":{"rendered":"
