Protection of Steel Structures with Paint Coatings in the Context of Environmental Pollution

The article presents important problems occurring in the operation of large-size steel structures protected by paint coatings. In our atmospheric conditions, corrosion cannot be avoided, even with use protective problem environmental pollution products and exfoliated then appears. When designing protection, durability protection is assumed based on corrosivity categories, but practice degradation coatings can occur much faster. premature peeling results, among other things, from its faulty application use. Steel structure repairs are usually carried out comprehensively, new requires removal damaged coatings, mainly sanding. As a result mechanical action abrasive material, old paints removed, which results very large amount waste that settles adjacent area. Due to age this often contains compounds such as lead, chromium or zinc, pose real threat natural environment around renovated buildings. article, observations directly exemplary renovation, actual scope emission was determined. This contribution further spectrometric studies determine exact area contamination identify heavy metals arising renovation
