Corrugated board, also called profiled board, is made of metal sheets such as color-coated steel sheets, galvanized sheets, galvanized sheets, etc., which are rolled and cold-bent into various corrugated profiled sheets. It is suitable for industrial and civil buildings, warehouses, Special buildings, roofs, walls and interior and exterior wall decoration of large-span steel structure houses, etc. It has the characteristics of light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fireproof, rainproof, long life and maintenance-free.
There are four types of primers for color-coated corrugated boards: epoxy resin, polyester resin, acrylic resin and polyurethane resin. Among them, polyester primer has good adhesion to the substrate and excellent flexibility. It is sensitive to humid environments and resistant to moisture. chemical.
The most commonly used topcoats for color-coated corrugated boards include ordinary polyester (PE), silicone-modified polyester (SMP), high weather-resistant polyester (HDP), PVC polyvinyl chloride plastisol, polyvinyl chloride plastisol and polyvinyl chloride plastisol. Vinylidene fluoride (PVDF), etc. PE color-coated galvalume corrugated sheet is based on color galvanized steel plate, and its topcoat is polyester coating. PE coatings have good adhesion to materials. Color-coated steel plates are easy to process and shape. They are cheap and have many products. There is a wide choice of colors and glosses.
Corrosion Resistance: The galvanized layer effectively prevents steel from rusting, while the color-coated coating further enhances the protection of the substrate, extending its service life.
Lightweight: Compared to traditional roofing tiles, color-coated galvanized roofing tiles are lighter, reducing the requirements on building structures and simplifying construction.
Rich Colors: The color-coated coating offers a variety of color options to meet different architectural styles and aesthetic needs.
Easy Installation: Its lightweight nature and specific panel design enable quick and efficient installation, significantly shortening the construction period.
Long Lifespan: Due to the dual protection of galvanization and color coating, color-coated galvanized roofing tiles possess excellent weather resistance and corrosion resistance, resulting in a long service life.
