Apart from developing its own products, FEAL is offering and the engineering to firms that need assistance in developing their own solutions, and constantly investing in new technologies of control products.

Development of products

Besides developing our own products, FEAL offers services to develop and design the system, which is closely associated with aluminum. Due to widespread use of Feal branches, and tertiary frame of our engineers, we can offer various services in order to obtain a quality finished product, and FEAL years of experience in working with aluminum.

Quality Control

Quality control we work according to the following criteria:

  • - Dimensional control
  • - Control of surface protection

Dimensional control

On measuring device ASCONA, we control the cross-sectional dimension of the profile according to drawing with accuracy of measuring 0.01 mm. Measurement results are shown in the measurement report generated by the device.

Devices for measuring surface roughness, check the surface quality of extruded profiles according to standard DIN 17 615 (Ra ≤ 3 ÷ 9 mm).

Creation of various elements and assemblies, which are produced on the line of machining and assembly line circuits, we control the operating requirements of the drawings.

Control of the mechanical properties of materials

Control the mechanical properties of the profile is done according to standards EN 755-2, which are:

  • - Determination of tensile strength (Rm)
  • - Determine the limits of flow (R0, 2)
  • - Determination of relative extension (A)
  • - Determination of hardness (HB / 2,5 / 625 / 30)
  • - The damping control seals

Control of surface protection can be divided into:

  • - control of anodized / anodized layer
  • - control electrostatic painted / coated layer

Control of anodized layer is made by Qualanod standards:

  • - Coating thickness) EN ISO 2360
  • - Dye spot test EN 12373-4
  • - Weight loss test EN 12373-7

Control of coated layer is carried out according to Qualicoat standards:

  • - Coating thickness EN ISO 2360
  • - Cross cut adhesion test EN ISO 2409
  • - Erichsen cupping EN ISO 1520
  • - Bucholz indetation hardness EN ISO 2815
  • - Mandrel bending test EN ISO 1519
  • - Impact test EN ISO 6272
  • - Gloss ISO 2813
  • - Calculation of colour differences ISO 7724/3
  • - Salt spray test ISO 9227
  • - Resistance to boiling water ISO 4628 – 2



FEAL in its range of services offers and testing and issuing certificates in accordance with the certification company ift Rosenheim. The way our test can be are: computer simulation conditions, or specific simulations in our own test center.

FEAL has successfully completed negotiations and signed the contract about certification of FEAL-s laboratory (test center) by IFT Rosenheim. The main purpose of the laboratory for validation of product quality is control of existing products as well as controls when developing new products. Laboratory has equipment that can perform testing of products (windows, doors and facades) to:

  • - Joint permeability according to EN 12207/1026,ASTM 283-04 and according to 12153/12152
  • - Watertightness according to EN 12208/1027, ASTM 331-00 and according to 12155/12154
  • - Loads to Wind Gust EN 12210/12211, ASTM 330-02 and 12179/13116

Test results can be used for informational purposes and to obtain documents attesting (certification by an independent institute in Germany ift-Rosenheim obtain this option) that can be used when issuing the CE mark for the export of goods into the EU.

Heat Calculations

After the training in Germany in the ift-Rosenheim and after passing the exam heat budget FEAL has obtained a certificate which is authorized to conduct heat budgets (UF) according to EN 10077-2.

The same calculations can be used when filling out the conditions for issuance of the CE-mark when exporting goods to EU member states. The certificate is valid for three years and includes periodic testing of knowledge of people a year are ahead of FEAL concerning the budget. To maintain a high level of knowledge in terms of thermal budget during the year to organize educational seminars in the ift-Rosenheim-in.


WinIso2D is a program used to simulate the thermal conductivity of the materials (typical cross section profile of the assembly). Calculations are based on the FEM-based method (the finite elements method) that allows a higher precision in the budget.

The result of analytical calculation of thermal conductivity of materials is largely similar to laboratory experiments, where the practice is necessary to prepare the sample window and then examine it.

As a final result of the analytical calculation are obtained through the heat transfer coefficient characteristic sections Uf and line losses Ψ psi. At the exit is possible to get the heat diagram that contains a complete picture of temperature streamline where possible to see where the greatest losses occurring heat.

Using the program is of great importance when creating the new series in which they can maximally improve the performance of new series in terms of thermal insulation.

The program is also used for the certified budgets Uf coefficients with the gain at the output document certified by the Institute ift-Rosenheim that they can be used to meet part of requirements for the issuance of the CE-mark when exporting goods to EU member states. In that way we give the buyer the opportunity to on the basis of input data (dwg drawings and descriptions of materials used in a typical cross-section) gets certified Uf budget for a very short time (up to a week).



Together with our project offices in Austria, Bosnia and Herzegovina and Croatia, we can offer expert consulting in the design of facades, all in compliance with European standards and certification of these products.

Together with our partners we develop, plan and implement creative ideas. Continuous dialogue allows us to apply our construction techniques, and provides a high standard of quality. Our willingness to fulfill customer requirements and the capacity in realizing high-tech solutions, makes us a very competent and reliable partners. We are customer oriented and flexible in approach. In addition to technical expertise in developing high-tech facade, or better said, "custom solutions" we enable delivers our own system components and complete solutions.

Our offer includes aluminum profiles for construction, ranging from simple to complex, large windows and facade elements for high-rise buildings with thermal break.

Own consulting, we are able to examine and attest, with the objective of complete and correct advice according to your query.



Osim konkretnih obuka, bilo u vlastitomu proizvodnomu pogonu, ili prilikom izvođenja radova, FEAL svojim kupcima koji su prepoznali njegove proizvode, nudi i specijalizirani program FEALSoft, za lakše kreiranje ponuda.

Fealsoft - program za podršku u izradi ponuda

Program omogućava izračun fasada FEAL (60K,60S,50FK,50PS ), prozora i vrata (T85,T65,T65 VS,T50,MILL 45,Z50,Z40) i a- grilja (G45,Z40,HARMO grilja ). Unosom pozicija zadatog objekta i odabirom vrste profila dobivamo vrijednost materijala pojedinih pozicija.

Program također daje mogućost izračuna količina materijala (profila ,okova i brtvi), rezne liste za uzradu u radionici, lista optimizacije, preliminarne statike za fasadne pozicije.

Sistemska baza podataka sadrži profile FEAL i odgovarajuće okove. Baza se neprestano može dopunjavati novim podacima prema potrebi. Imamo mogućnost unosa sistemskih okova za određenu vrstu prozora ili vrata. Ima mogućnost izrade pozicije u CAD-u okruženju i prenošenje u SOFT, optimizacije rezanja pločastih materijala (limovi,kompozitne ploče).
