Painted Steel Coil

The billboards shall be exposed to severe environment such as wind, sunshine, rain and temperature difference for a long time, with special requirements for materials, and the painted steel coil shall be perfectly matched:

Outstanding weather resistance and color retention of painted steel coil:

·Core requirement: the primary task of billboards is to keep the picture bright, not fade and not fade.

·Color coating roll solution: the painted steel coil with high durability polyester or PVDF finish can effectively resist the degradation of ultraviolet light and ensure that the color of the advertising picture remains bright in 5-10 years or more.

Strong corrosion resistance of painted steel coil:

·Core needs: Resistance to rain water, atmospheric salts (coastal areas), pollutants (industrial areas).

·painted steel coil Solution: Galvanised or aluminized zinc substrates provide "sacrificial protection", while organic coatings form a dense physical barrier, providing dual protection to ensure that billboard frames and panels are free from rust and corrosion and extend overall life.g.

Light and high strength of painted steel coil:

·Core requirements: Reduce the weight of billboards, thus reducing the requirements and cost of supporting structures (such as columns and walls) and facilitating transportation and installation.

·painted steel coil solution: the painted steel coil plate is very light compared with concrete or solid steel plate, but it has high strength and can withstand wind load.

Excellent processability and modeling ability of painted steel coil:

·Core requirements: billboards need various shapes, such as plane, arc, special-shaped, etc.

·painted steel coil solution: the color coating roll can be easily cut, bent, rolled, punched, etc., and can produce flat plate surface, cylindrical lamp box, or reinforced panel with curled edge.

Economy and efficiency of painted steel coil:

·Core requirements: control of manufacturing and maintenance costs.

·painted steel coil solution: it integrates structure, protection and decoration functions and can be installed quickly. There is little need for anti-corrosion painting like wood in the later period, or frequent rust prevention maintenance like common steel plate, so the whole life cycle cost is low.

Appearance and cleaning of painted steel coil:

·Core requirement: flat and smooth surface, easy to clean and maintain.

·Solution for painted steel coil: the coating surface is dense, not easy to be stained with dust, and can be kept clean after being washed by rain. For PVDF coatings, self-cleaning is better.

·Example: Large single-column billboard with painted steel coil on the roof

·DESCRIPTION: A huge billboard on the roof of a commercial building, 10 m x 20 m.

·Usage: The panel of billboard is spliced by several pieces of aluminum zinc plated base plate PVDF finish painted steel coil after being flattened and cut. Steel frame support at back of panel. The advertising picture is a huge poster of a famous mobile phone brand directly painted on it.

·Why Choose it:

·PVDF topcoat: PVDF ensures that the blue color of the brand logo will not fade for many years due to the strong UV radiation on the roof.

·Aluminized zinc base plate: the roof is subject to rain and snow all the year round, and the aluminized zinc base plate provides the top rust protection to ensure the structural safety.

·Light weight: reduce the load on the roof structure.

·Case 2: Double-sided and triple-sided advertising board with painted steel coil beside the expressway

·Description: A billboard composed of a lot of triangular prisms on a column beside the expressway, which can be turned over to form three different pictures.

·Usage: Each triangular prism is formed by precision rolling of polyester finish color coating roll of galvanized substrate. Plates are required to have good flatness and uniform dimensions to ensure smooth turnover.

·Why Choose it:

·Polyester finish: high cost performance, can meet outdoor durability requirements, and good adhesion, suitable for subsequent rolling processing.

·Excellent processability: the painted steel coil can be perfectly rolled into the required prism shape.
