The material is removed of rust, coatings or scales to the degree of purity SA 2.5-3. We use steel abrasives with a diameter of 1.6 to 1.8 mm. It is the optimal preparation before subsequent surface treatment. We mainly use an automatic blasting chamber with a capacity of 1,000 kg. We blast larger units manually in the blast chamber.
This is good for painting galvanized and raw surfaces. We use outdoor polyester paints especially from the Swiss manufacturer IGP. At the customer's request, we can spray in any RAL shade and the desired structure. The maximum dimensions of parts for Komaxit are 5 x 2 x 1.4 m, the weight of the painted part can reach up to 400 kg.
Wet coating is mainly used for dimensionally large constructions. We use paints by the producers Perge and Hempel, and others can be applied based on the client's requirements. For wet coating by high-pressure spraying, we have a painting booth and drying booth, substantially reducing drying times. We use approved coating systems for the railway directorate Správa železnic and the Road and Motorway Directorate. Wet coating is mainly used for dimensionally large constructions.
We perform three types of galvanization: hot-dip, spray or cold galvanizing. This involves applying molten metals with a stream of air to a pre-blasted material. The zinc layer is applied according to the type of galvanizing in the range of 5 to 150 µm. Hot galvanizing by spraying, called metallization, creates a rougher surface suitable for further application of covering and colored materials. If necessary, we also provide hot-dip galvanizing, which can serve as the final surface treatment.
The most commonly used trees – be they the Siberian spruce or tropical Brazilian cherry (jatoba) – are characterized, thanks to their hardness, by their natural resistance to rot, mold, fungi and insects. Therefore, they only receive an appropriate oil finish applied regularly. In general, teak oil coating must be applied when the surface of the wood becomes matte and rainwater droplets cease to remain on the surface and begin to soak into the wood. It is recommended to apply the first coat by the end of the first month of use of the product at the latest. This application should be repeated at least twice per year.
