Steel chimneys

During the 70s, the number of steel chimneys has increased. That was when special steels such as Corten and similar grades began to appear on the market. The resistance of the steel chimney is at a high level, but you still have to be careful. If the chimney top, for example, is incorrectly designed and cannot repel rain and snow, aggressively stagnant water remains, with rapid corrosion as a result. This in turn means that when the top is corroded, for example, sulfur dioxide or hydrochloric acid penetrates into the chimney and attacks load-bearing structures, resting surfaces, insulation, ascent ladders, back guards and electrical fittings. Clogged drainage pipes and poor ventilation.

There will be similar damage if the top drainage pipes become clogged and aggressive water leaks into the jacket. Poor ventilation of the inner jacket can also cause damage.
