Belzona Facts

Previously the eroded/corroded areas had been repaired by the customer's own staff welding and grinding those areas almost each year during seasonal shutdowns for maintenance. This sort of conventional repair presented a safety risk and was time consuming. The decision to use cost-effective Belzona protective system saved company money, time and reduced risk. In addition Belzona coating will provide long term resistance to the chemical attack and corrosion.
