22/September/2020  Coatings and Finishes    It takes me back to my initial blogs where I quoted that " God is in the Coating ". Seems like that’s not an amateur statement to make. The productivity, especially, in huge spans and in large structures depend legitly on the type of the coating and finishes the members obtain. The efficiency of Steel members is directly proportional to the type/ quality of coating.     Although steel was introduced in building construction because it was fire resistant, to replace timber, Steel itself is not that Fire R esistant . Another major disadvantage with steel with respect to context is the weather. Humidity causes C orrosion and rusting is evident. Certain issues pertaining to the Cleanliness and Maintenance also add to this list, like the trusses becoming a roosting place for pigeons, problems regarding the height of the structure and the equipment required to clean it. The frequency and efficiency of maintenance has a b...

24/August/2020 Impact of Weather conditions on the building material - Steel  Temperature - Steel expands in summer, when the temperature is down, it might contract. This repeated expansion and contraction might affect the durability and the tensile strength of the steel.  Humidity and Precipitation - The major factor that has an impact on steel - Corrosion, erosion, rusting - When there is moisture content in the air, the steel tends to react with the water.  Wind - Contains salt content - steel is reactive to salt  Disadvantages of Steel - Impact of weather conditions on Steel  High atmospheric humidity increases the moisture content in air. A steel surface is allowed to begin to rust when the relative humidity in the air climbs above 50%, and steel surely rusts when the relative humidity reaches 80%. This can result in flash rust that collapses the coating. If it is painted, it might result in blistering and delamination of the surface coa...
