Influence to ecologies and climate on corrosivecondition of the metallic constructions

There are different factors that influence corrosive processes, main of them are climate and ecology. Corrosion of the metallic constructions, roofs and different parts of construction projects often leads to their collapse, human victims and material losses. This article gives the analysis of corrosion causes, leading to reduction of metal's section. It also includes the research of annual corrosive speeds of some constructional materials being in contact with different substances that are usually part of motor-car or industrial emission. Given recommendations on the evaluation of corrosive speed, monitoring of rods' condition and preventing emergency situations.
