GUANXIAN 0.11-2.5mm Thickness Prepainted Colour Coated Galvalume Steel Coil Plate Suitable For HVAC Pipelines and Housing Construction
PREPAINTED GALVALUME STEEL PLATE
prepainted galvalume steel plate refers to a type of steel developed in the late 20th century. It is a coated steel product with a shell made of a high-strength aluminum-zinc-silicon alloy with a high aluminum content. The name comes from the two main alloys used to make this material: aluminum and zinc. It nominally contains 55% aluminum, 43.5% zinc, and 1.5% silicon (by weight) and has excellent adhesion to steel substrates.
Pre-painted steel provides unparalleled results at every stage of the process. Pre-painted steel is widely popular in a variety of industries for its rich color and texture selection, excellent adhesion, reliable surface consistency (can be cut, bent, and generally processed without damaging the finished coating), and more efficient production processes.
BENEFITS
Premium galvalume sheets are a subset of pre-coated galvalume sheets that meet higher quality standards. The term "premium" indicates that these sheets are of the highest quality, free of defects or blemishes, and meet strict industry standards. Premium galvalume sheets undergo rigorous quality control measures during the manufacturing process to ensure consistent and reliable performance. These sheets are highly sought after in applications that require a high level of durability, corrosion resistance, and visual beauty.

COATING TYPES
Polyester PE:
Good adsorption, rich colors, wide range in formability and outdoor production, medium chemical resistance, and low cost.
Silicone polyester SMP:
The hardness, wear resistance, and heat resistance of the coating are good; as well as good external anti-powdering and glass retention, general flexibility, and medium cost.
High polyester polyester HDP:
Excellent color retention and oxidation resistance, excellent outdoor adsorption and anti-powdering, good film absorption, rich colors, and excellent stability.
Polyvinylidene fluoride PVDF:
Excellent color retention and resistance, excellent outdoor adsorption and anti-powdering, excellent solvent resistance, good moldability, oxidation resistance, limited colors, and high cost.
FEATURES OF PREPAINTED STEEL SHEET
* It has good durability, and its corrosion resistance is longer than that of galvanized steel plate;
* It has good heat resistance and is less prone to discoloration at high temperatures than galvanized steel sheets;
* It has good heat reflectivity;
* It has processing performance and spraying performance similar to that of galvanized steel sheets;
CORROSION RESISTANCE OF PREPAINTED STEEL SHEET
After a period of use, the performance and service life of the galvanized color-coated sheet will be reduced. And it needs to be repainted due to various environmental factors. The most basic requirement for repainting is to have a certain adhesion with the original coating and good durability. According to the use environment, outdoor galvanized color-coated sheets can be divided into three categories. The first category is used in natural environments and requires anti-corrosion effects. For example, galvanized color-coated sheets are used for isolation at construction sites; the second category is used in natural environments and requires certain anti-corrosion and appearance effects.
APPLICATIONS OF COLOR-COATED GALVALUME STEEL SHEETS
Heating and Ventilation Applications: Pre-coated galvalume steel coils are used for heating and ventilation applications. Galvalume steel can withstand temperatures up to 315 degrees Celsius and can be used in air conditioning units and HVAC ducts, solar heating panels.
Agricultural Applications: Galvalume steel has a long service life and is suitable for a variety of agricultural applications, from silos (for storing grain), boxes (storing grain, fruits, vegetables, feed), curing and drying facilities, greenhouse frames to rainwater collection tanks.
