Prepainted Steel Sheet with 4 Layers of Polyvinylidene Fluoride Coating
Exellent choice for building exteriors
4 Layers of fluoride resin coating are applied to a hot-dip galvanized steel sheet to significantly enhances the inherent properties of steel sheet: durability, weather and corrosion resistance.
Most common cold rolled steel sheet is used as its base metal to cut down the production cost. Due to its durable quality, replacement is unnecessary for at least 30 years.
The hot-dip galvanized steel sheet used for plates possesses significantly enhanced corrosion resistance through the Z27 painted sheets (zinc weight 275g/㎡ or more). Special management techniques for molten zinc pot and ultra smooth skin pass procedure are adopted to acquire a smooth and elegant surface.
The tension leveler is installed in the continuous coating facility, which conducts the correction process for flatness.
The pre-coated steel sheet produced in continuous coating facilities, using the roll coating method boasts consistency in color and an elegant appearance in comparison with the post coating product made by the spray coating method.
High performance of the steel sheet is achieved through the Curtain Wall method, which significantly reduces the construction period.
Adaptable to a variety of needs
The steel sheet can be used not only for low-rise buildings but also high-rise structures. Its superior quality as a building exterior material is suitable for the construction of new buildings as well as remodeling of existing structures.
30-year quality guarantee
Excellent weather and corrosion resistance protects the coating color and polish from relentless weather conditions such as ultraviolet rays, wind or rain. A 30-year guarantee is offered for products used in ordinary conditions.
