Metal or steel door frames are structural elements designed for mounting door leaves into wall openings. They are manufactured from sheet steel, ensuring high strength, resistance to mechanical damage, and a long service life even in demanding environments. These properties make them suitable for standard interior and security doors in both residential and commercial buildings. <\/p>\n
The range includes two basic types based on the installation method:<\/p>\n
One-piece frames (Kooperativa, Chadim) \u2013 designed for wet installation (walling-in) during the rough construction phase. They create a solid, permanent bond with the wall, ensuring maximum stability. This type is ideal for new builds or extensive renovations where the frame can be installed before final surface finishes.
\nTwo-piece frames (Kooperativa, Chadim, Soleco) \u2013 designed for retrofitting into finished wall openings. They consist of two parts that join around the wall during installation, eliminating the need for masonry work. This makes them ideal for renovations and finished interiors where fast, clean installation without structural wall intervention is required. <\/p>\n
From a structural standpoint, the frames can be equipped with a sealing groove, preparation for door closers, or other modifications based on specific use. Variants are available for both rebated and non-rebated (flush) doors, allowing them to match various interior design solutions. <\/p>\n
Regarding surface finish, frames are standardly supplied with a primer (transport coating), which serves as a base for the final finish. This can be chosen according to project requirements \u2013 most commonly via painting or powder coating in RAL shades. Selected variants are also available in stainless steel. <\/p>\n
Kooperativa, Chadim, and Soleco metal frames represent a reliable solution for a wide range of projects \u2013 from residential interiors and administrative buildings to technical and industrial spaces where emphasis is placed on strength, functionality, and long-term durability.<\/p>\n","protected":false},"excerpt":{"rendered":"
