When installing new roofs on commercial buildings or constructing a new home for a family member, many individuals may prefer thinner galvanized roofing sheet materials because of cost considerations. But the thin galvanized roofing sheet form pressed from the thinning hard metal sheet is actually quite weak, and hence it is not at all as strong as the thick galvanized roofing sheet materials that are available on the market today. If the roof is to be galvanized with a galvanized roofing sheet that is less than one inch thick, there is a high risk that the installation will fail because the thin metal will be unable to withstand the tremendous amount of pressure that is placed upon it. This may even result in the entire roof being blown off, causing irreparable damage to the building.
Many individuals are not aware that if the material used is not properly galvanized, there is a great risk of the formation of steel bars or iron fatigue nha khung thep. These formed structures are known as “fractured bars”, and if not properly protected during installation, they can become a hazard in later years. One of the major disadvantages of using a thin metal roof as the backing for a pitched roof is that it becomes vulnerable to the development of these galvanized corrugated structures. When the weather turns cold during winter and hot during summer, it is extremely difficult to prevent the formation of these galvanized bars during winter months due to the lower air temperatures that occur during that time.
Many consumers do not realize that there is a difference between corrugated and galvanized steel sheet materials. Corrugated steel, which is typically made with aluminum, zinc, or steel, has been found to have significant levels of impurities, including lead and cadmium. Studies have shown that the level of lead, cadmium, and other metals that can be found in corrugated steel is extremely dangerous for human health. With this in mind, a thick, non-corrosive layer was added to galvanized steel, allowing the protection of human health, as well as preventing the development of steel bars through galvanic corrosion.
Roofing that is galvanized has additional benefits. It is significantly more durable, because the galvanized surface has enhanced corrosion resistance. Additional protection comes in the form of a barrier against ultraviolet radiation. Ultraviolet radiation causes a variety of skin discoloration problems, including white spots, age spots, as well as liver spots. By adding a barrier against ultraviolet radiation, a galvanized corrugated read can provide greater protection from such discolorations.
Many consumers are unaware that the galvanized steel sheet must undergo hot-dip galvanization before it is suitable for roofing applications. Galvanized hot dip galvanized sheets must be dipped with a specially designed, electrically charged electric dipstick that contains an antimony coating and bromine in order to achieve good corrosion resistance. The hot-dip galvanized coating is applied in thin, even strokes, which ensures a uniform, even coating across the length of the sheet. This ensures a much longer service life for your home or building, as well as improved visual appearance and durability.
Hot dip galvanized roofing materials are available in both wet and dry configurations, providing a variety of choices for your application needs. You can choose to go with either a corrugated sheet or a fully-customized hot dip galvanized flat roof. Either one will provide you with long service life, better color match consistency, and increased corrosion resistance. If you want to go with either a wet or dry system, remember that it is important to apply the coating as per manufacturers’ directions, and to always test a small portion of the roof before fully coating the entire thing.
