In the drawings railings are often used forged and pressed grape leaves, birch, there are many variations of the surface of the rod forging to give to the example of the kind “the vine” or “snake skin”. As a handrail either used bandwidth of 40 * 4 by wooden railings or metal laminate “classic” handrail or profiled tube 50 * 25 with laminated faces, or twisted in a plait of several bar rail. Recent years, a very popular figure “modern” – when the square (rare – round) rod unchain a smooth transition in the same plane, then turns to another plane, and again gradually unchain. Soft lines of “modern” fit virtually any design of interior and exterior home, with the well-being combined with plant motifs and classic pattern. After assembling the finished picture rails cleaned kartsovochnymi brushes from scale and rust, are processed in the blast chamber (which few companies perform this necessary for the treatment of iron stage), treated with acid (this step is passed by an overwhelming majority of firms) and covered with primer and a coat of paint in two phases, which ensures the safety of a decorative kind railing for years. Also, for giving effect to the colorful old layer is applied patina of different shades, highlights and highlights the brushed and the beauty of metal. There is a way to paint the metal in the powder chamber, where a special dye in the form dry powder consisting of epoxy resin and metal powder is applied electrostatically by the metal surface and a couple of hours put into the chamber with an approximate temperature of about 200 degrees Celsius, where baked in a very strong layer of paint coatings.
The undoubted advantages of this technology – a beautiful, smooth and durable coating that protects the metal on the considerable amount of time Cons – Failure surface treatment technology metal before painting forged railing, so that the powder layer has adhesion to the metal surface, and after just six months or a year begins to flake off under pressure formed inside rust. The minus also includes an easy skolkost powder layer under the influence of other metal objects and the inability to touch up on-site quickly. After completion of installation signed certificate of acceptance of delivery of works and warranty (in different firms at different stages), which in principle is needed only for paintwork, because the metal itself is worth many decades without a change in the absence of rust does not change its operating qualities.
