Prepainted Galvanized Iron Coils

Coil of Steel is a multi-functional building material with galvanized, aluminized zinc or electro-galvanized steel sheet as the base material, coated with organic paint on the surface and baked to cure. It has the following significant advantages and a wide range of applications:

Core Advantages of Color-coated Steel Coils

1. Lightweight and high strength, cost-saving

Color-coated steel coils are lightweight (about 1/6 that of traditional materials), which can significantly reduce the load on building structures. They are particularly suitable for the renovation of old buildings or areas prone to earthquakes. Its base material is made of high-strength aluminized zinc or galvanized steel plate, which has strong impact resistance and a service life of 15 to 50 years.

2. It has excellent corrosion resistance and weather resistance

Galvanized or aluminized zinc base plates combined with organic coatings form a dual protection, which can resist erosion from acid rain, salt spray, ultraviolet rays, etc., and have a service life 1.5 times longer than that of ordinary galvanized steel plates. Some coatings (such as PVDF) can remain stable under extreme temperatures (-30℃ to 70℃) and withstand wind force up to level 12.

3. Beautiful and diverse, with strong decorative properties

The surface coating can be customized in various colors (such as gray and white, sea blue, brick red, etc.) and patterns, featuring both metallic luster and stone texture. It is not prone to fading over long-term use and has low maintenance costs.

4. Convenient construction and high efficiency

Color-coated steel coils can be directly cut and bent, suitable for roofs with slopes ranging from 12° to 90°. Dry installation only requires 4 to 6 nails for each piece to be fixed, supporting assembly line production and shortening the construction period.

5. Environmentally friendly and economical, recyclable

The production process causes less pollution, reduces the paint spraying step, and the materials can be 100% recycled, meeting the standards of green buildings. It offers high long-term cost performance and low maintenance costs.

6. Functional optimization

High-temperature resistance and heat reflection: The hot-dip aluminized zinc substrate has twice the ability of galvanized sheet to reflect heat and light, is less prone to oxidation at high temperatures, and has a significant energy-saving effect.

Sound insulation and heat insulation: The sandwich panel structure can enhance the thermal insulation and sound insulation performance, making it suitable for places with high comfort requirements.

Specification

Application Scope of Color-coated Steel Coils

1. Construction field (accounting for 80%

Industrial and commercial buildings: For the roofs and walls of factories, warehouses, and shopping malls, corrugated boards or polyurethane sandwich panels are commonly used.

Public facilities: gymnasiums, airports, bus shelters, ventilation ducts, etc., taking into account both aesthetics and functionality.

Civil buildings: Villa and self-built house "flat-to-slope" renovation, lightweight design reduces structural pressure.

2. Home appliance and furniture manufacturing

The shells of refrigerators and air conditioners are made of color-coated galvanized steel sheets, which are both aesthetically pleasing and corrosion-resistant.

Surface decoration of furniture such as bookshelves and cabinets to enhance the texture of the products.

3. Transportation and Advertising

The interior parts of automobiles, oil pans and other components, as well as the shells of high-end models, are coated with high-weather-resistant coatings.

Billboard and sign production, with bright and durable colors.

4. New Energy and Temporary Buildings

Building-integrated photovoltaic (BIPV) roofing, adapting to the growing demand for new energy.

Temporary construction site houses and prefabricated houses can be installed quickly and reused.

Market Trends and Selection Suggestions

High-end and customized: Future demand will lean towards environmentally friendly (such as PVDF coating) and highly weather-resistant products, especially in the fields of new energy vehicles and smart home appliances.

Substrate selection:

(1)Hot-dip aluminized zinc substrate: Suitable for outdoor buildings, with corrosion resistance 2 to 5 times that of galvanized sheets.

(2)Galvanized electroplated substrate: Suitable for indoor household appliances, with excellent processing performance but relatively weak weather resistance.

Color-coated steel coils, with their comprehensive performance, have become core materials in modern construction and manufacturing, especially excelling in lightweight, environmental protection and adaptability to complex climates. When selecting the type, it is necessary to choose the coating type (such as polyester, silicon-modified polyester or PVDF) and the substrate in combination with the specific scenario to achieve the best cost performance.
