Thousands of tons of steel are used in general construction each month. Hot-dip galvanized steel is used in various types of construction, including office buildings, government structures, retail establishments, apartments, schools, stadiums, light poles, bridges, and tunnels. Much of the steel is protected by hot-dip galvanizing, which allows it to withstand the corrosive attacks of the environment, weather, chemicals, and exhaust fumes. From hydrochloric acid through ammonium chloride, zinc chloride, and zinc ammonium chloride double and triple salts, Kron Oilfield Services Co. offers a complete line of chemicals for galvanizing.
