Corrosion-proof hardware

Where rust and corrosion have no chance!

Keriko Plast Ltd offers high-quality products with guaranteed anti-rust protection – МАСО TRICOAT.

This special treatment is designed by MACO specialists for window and doorframes in highly corrosive atmospheres.

Ambient influences and certain aggressive substances can cause premature corrosion of metal parts. Until lately, no adequate coating existed to resist those extreme factors.

Now MACO offers their customers the innovative TRICOAT treatment ensuring a durable and efficient protection of all surfaces. This new coating is unique for its startling results in corrosion testing.

Spheres of application

Metal hardware is subject to different atmospheric conditions and industrial pollutants that cause it to corrode and make it unusable. That is why MACO TRICOAT is an extremely versatile product and can be used as standard door/window hardware, too. It guarantees stability and durability. It is absolutely essential in conditions where galvanized surfaces prove to be insufficiently resistant to corrosion.

Thanks to its unique three-layered coating, the TRICOAT hardware ensures lasting and problem-free use with no risk of rusting or other defects on the metal parts of joinery whatsoever.

Great solution for the visible parts of hardware!

MACO TRICOAT is the best choice in a wide variety of cases. Keriko Plast strongly recommends its use in the following occasions:

  • Coastal and island locations
  • Locations with high concentration of lactic acid vapours (dairy farms and factories)
  • Locations with steady influence of chlorine fumes (swimming pools, baths)
  • Places with high humidity (basements, laundries)

The upper and lower hinges are the metal parts that are most exposed to corrosive influences. For this reason, a special powder-coating technique is used.

With the TRICOAT treatment, hinges are extremely resistant not only to corrosion but also to scratching, wetness and staining.

TRICOAT is available in light grey.

Thanks to its pleasant silver shade, MACO TRICOAT ensures a stylish optical effect. Windows and doors with this type of hardware look more attractive.

  • Pleasure and Comfort at Any Time of the Year

    – For your comfort at any time – For the pleasure to look at your new window and relish the cosiness, style and beauty it brings to your home and office   With the energy-saving, modern solutions from Keriko Plast, both for cold and warm weather, this is not only possible but also a proven fact – due to the triple glazing, the increased distance between panes, the high-quality materials and the all-season panes.   Few of us actually realize how much money is wasted because of old and ineffective windows. In fact, old technologies are the main cause for energy loss. Using old windows with PVC, aluminium or wooden frames produced and assembled in the 1990s can lead to unjustified expenses.

  • Cleaning Materials

    Keriko Plast offers cleaning solutions for white and foil-coated (coloured) PVC profiles. These chemicals are specially produced for this type of material and do not damage its surface. The main use of the solution is for the final cleaning and antistatic treatment of the manufactured product. The chemical removes the high static electricity from the PVC profiles and in this way reduces their tendency to attract dirt particles. The preservative VEKA solution has lasting effects and is used to treat window-frame surfaces against harmful atmospheric conditions.

  • Ventilation

    In relation to new energy-saving norms, more and more measures are taken for a better heat insulation. High insulation characteristics lead to reduced heating expenses, raw material economies, reduced harmful gas emissions in the atmosphere and less negative influences on the ozone layer. That is why the requirements for modern window and doorframes are for even better insulation properties and minimal heat loss. Due to the high energy-saving characteristics and tight sealing of window and doorframes, it is vital to ensure adequate ventilation. Depending on the specific situation, it is advisable to regularly let fresh air into the room if the windows are not opened often. Different smells, gasses, moisture and harmful chemicals affect not only your comfort but can also damage the structure and outer covering of the walls. Good ventilation has the following functions: - Ensures good air quality and healthy conditions - Prevents water condensation and fungal growth thanks to the improved air circulation Sanitary norms recommend between 10 and 25 m3 fresh air per hour per person. About 60 m3 of fresh air an hour is needed for a room with 3 people inside. For a house, the advisory average air volume coefficient is 0.5 h-1 (DIN 1946-6). It means that every hour half of the air inside should be refreshed, and to do this, special measures have to be taken. Normal ventilation through the window frames is not sufficient to meet the above-mentioned ...

  • Save 20%

    Energy Effectiveness Programme With the Energy Effectiveness Credit, you pay 20% less if you are an individual customer or 30% less for group projects. After you replace your old door and window frames, your heating bills can drop with 15%.   Why save energy in summer and in winter and how? There are two reasons to save energy. First, you can save the planet and, second, you can save your money. A third of all carbon dioxide emissions come from homes. Carbon dioxide plays a major role for climate change. In the last century, average Earth temperatures have increased by 0.6 centigrade. It doesn’t sound so serious but scientists expect a further climate warming in the 21st century between 1.3 and 5.9 centigrade. This temperature change can have dramatic consequences for our planet. Making little changes, we can contribute to reducing carbon dioxide emissions, helping to save our planet and improving our financial situation. As we try saving money in our homes, it is the most logical to look for the places where the most heat is lost. The average heat loss through the windows and doors of our homes is 10-15%. The Energy Effectiveness Programme ensures households and proprietors’ associations from all over the country the opportunity to take advantage and get a tied loan and also free financial help through the Bulgarian commercial bank network.
