KFK's metal sheet production uses multiple technologies for load bearing, decorative and architectural metal sheet processing.
Metal sheets can be used as components for unitized facades, decorative interior and exterior finishing sheets, metal claddings on facades, load bearing sheets and cold formed profiles, ventilated facades etc.
By using available Trumpf machines it's possible to produce most complexed flat and curved geometry metal panels with various finishing.

Welding of metal sheets, aluminium and stainless steel and grinding to smooth joints and corners. By welding its joints achives maximum visual appearance and water tightness of metal sheets.
Thermal cutting of low alloyed, stainless steel and aluminium sheets up to size of 4000 x 2000 mm.
Punching of thin metal sheets low alloyed, stainless steel and aluminium up to size of 6000 mm lenght, thickness up to 3 mm.
Cold forming of metal sheets in all flat shapes using Trumpf made bending machines. Bending of sheets in lenghts up to 4500 mm using force up to 230 metric tons.
Latest state-of-the-art technology glass production area of 6800 m2 in KFK's facility is constructed with high degree of automatization of production processes where impact of human error is reduced to a minimum. Glass products are 'jumbo' size up to 6000 * 3200 mm.
All production lines for each phase of glass processing are in one place, which significantly reduces time for multiple processing of glass panes or assembly of compound glazings.
Overall production is software controlled, enabling the traceability of production to a single unit of production.

Furnace for flat glass thermal toughening or heat strengthening for glass thicknesses 4-19 mm in jumbo sizes.
Incorporated automated line scanner determination of roller wave and edge deformation.
All thermally toughened glass can be additionally subjected to heat soak test, which significantly reduces the spontaneous breakage risk.
All single glass units processed in other KFK's glasswork lines can be assembled in double or multiple insulated glass units, in jumbo sizes and in thickness up to 100 mm, with the possibility of stepped-edge units.
Total production capacity of 200 000 m2 units per year in one shift (based on average unit size of 2,5 m2).
Ceramic ink digital prints standard or custom designed patterns or images in a over pressurized clean-room climatized environment.
Internal quality control acording to EN ISO 12543 standard series and CE marking acording to EN 14449 standard for laminated and laminated safety glass.
Each glass pane is washed automatically before entering the printing/enamelling process.

KFK's facade test facility is located in main KFK production factory Rugvica, Dugo Selo, near Zagreb. Basic and foremost meaning of our test facility is systematic checking, verification and quality control variety of facade system according to all proscribed regulations and standards.
All impact test we can provide in accordance with EN 14019:2004 and Tehnical note number 76 for the UK.
Soft body test may be caried out using the double tyre impactor as described in EN 12600 or a convas spherical/conical bag with a diameter of 400 mm and filled with 3 mm diameter glass sphere to give a mass of 50 kg.
Impact tests are carried out by allowing the impactor to swing in pendulum movement to hit the specimen normal to its face. The height through which the impactor swings is adjusted to give required impact energy.
A steel ball of 50 ± 1 mm or 60 ± 1 will be used
The ball shall be either:
- Dropped from a tower onto a horizontal surface, or
- Suspended as a simple pendulum and allowed to swing against a vertical surface
Specifiers can require that cradles are designed to limit severity of potential impacts to values given in tables 4 and 5 of Tehnical note No 75.
Basic and foremost meaning of our test facility is systematic checking, verification and quality control variety of facade system according to all proscribed regulations and standrads.
We are able to perform various tests such as:
AIR PERMEABILITY | test, method | EN 12153:2000 (ASTM E283) |
RESISTANCE TO WIND LOAD | test, method | EN 12179:2000 (ASTM E330) |
WATERTIGHTNESS | aboratory test under static pressure | EN 12155:2000 (ASTM E331) |
WATERTIGHTNESS | laboratory test under dynamic condition of air pressure and water spray | EN 13050:2011 (AAMA 501.1-05) |
SEISMIC MOVEMENT | test, method | (AAMA 501.4) |
For Sound Testing, we use the Brüel & Kjær Class I measurement system.
Laboratory measurement of the flanking transmission of airborne sound between adjoining rooms and measurement of airborne sound insulation facade elements, doors and windows.
We are able to perform various tests such as:
1. Laboratory measurement of the flanking transmission of airborne sound between adjoining rooms – Test method EN ISO 10848-2
2. Measurement of airborne sound insulation – Test method EN ISO 10140-2 (ASTM E90)
Unitized facade system is the best quality facade system currently available. Factory fabrication processes are in controlled environment with highly skilled experienced personnel and state of the art assembly and transport tools and machinery. With its 10 individual assembly lines whole assembly area is covered with vacuum lifters, cranes and rails for assembly lines.
Each facade assembly stage is under surveillance by one head of production and QC engineer in charge of specific project.
