China Roof Tiles, Home Appliance Panels, Anti-Static Panels No Fingerprint Galvalume Coil Gl Steel Coils Az100~200gms

Product Description

Galvanized/Galvalume coil/roofing sheet

The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. The production process of galvanized steel is similar to that of galvanized steel, which is a continuous molten coating process. The galvalume steel has better corrosion resistance than galvanized steel of the same thickness when exposed to the same environment. The galvalume steel not only has good corrosion resistance, but also excellent adhesion and flexibility with color coated products.

1. Heat reflectivity The heat reflectivity of galvanized steel sheets is very high, which is twice that of galvanized steel sheets. People often use it as a material for heat insulation.
2. Heat resistance Aluminum-zinc alloy steel plate has a good heat resistance and can withstand high tempera tures of more than 300 degrees Celsius, which is very similar to the high-temperature oxidation resistance of aluminum-plated steel plate.
3. Corrosion resistance The corrosion resistance of galvanized steel coil is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion- resistant substances from further corroding the interior.
4. Economy Because the density of 55% AL-Zn is lower than that of Zn, the area of the galvanized steel sheet is more than 3% larger than that of the galvanized steel sheet with the same weight and the same thickness of the gold coating.
5. Easy to paint The aluminum-zinc plate has an excellent adhesion between the paint and the paint can be painted without pretreatment and weathering.

Coating Introduction

Prepainted steel is also called color coated steel. It is based on metal coils (cold-rolled sheet, hot-dip galvanized sheet, aluminized sheet, high aluminum alloy sheet, stainless steel sheet, etc.) It is made by coating or laminating various organic coatings or plastic films on the surface.

Prepainted colour steel coil/sheet

give the appearance of an actual tiled roof, ideal for roofing all types of buildings however look exceptional on log cabins, summer houses, garages and domestic buildings. These roofing sheets are available in thickness 0.13-0.6 mm; Protective film, Wrinkle, Matt, Metal Embossed and Printed finishes and in all RAL. colors.

Color-coated roll composition

Primer coating (Top)	It is helpful to strengthen the adhesion to the substrate so that the paint is not easy to desorb after the paint film is permeated, and it will also improve the corrosion resistance because the primer contains corrosion inhibitors, such as chromate pigments, which make the anode passivation. To improve corrosion resistance.
Front coating	It shields sunlight and prevents ultraviolet rays from damaging the coating; when the primer coating (Top) reaches the specified thickness, it can form a dense shielding coating, reducing water and oxygen permeability.
Primer coating (Back)	The effect is to prevent corrosion of steel plates from the inside.
Zinc coating	Generally use galvanized or galvalume steel, this part of the product's service life has the greatest impact, the thicker the coating corrosion resistance performance is better.

Coating Suppliers

PE has good adhesi on wi th gal vani zed steel, steel with PE can be easy to modelling, it is cheap and suitable for multiple products. Many different options can be chosen from color and gloss. In the normal condition, i t has 5-8 years of corr osi on protecti on, whereas the product life can decrease once in the highly polluted area

SMP has a longer life, but with higher costs and lower cohesion & formability, its anti-corrosion period up to 10-12 years

HDP High molecular resin and fewer polymer branches, forming a stable bond, not easy to be photo-decomposed. This paint has high color retention, UV resistance, outdoor durability and anti- chalking performance, it has 15 years of corrosion protection

SRP It has excellent resistance to resin degradation in long-term sunshine and high-temperature environment, excellent durabil i ty but hi gh hardness, l asti ng 15- 20 years of anti-corrosion

PVDF High performance in anti-corrosion and color retention. It is the highest standard pai nt mat eri al i n bui l di ng const r uct i on. Lasting 20-25 years anti- corrosion, but with high cost. There are limited color to choose from when using this paint, and onl y l ow gloss paint can be used
