What is aluminum roofing sheet?

Roof shingles are used to protect the roof from weather conditions. They are installed on the roof. They are usually made of aluminum, but can also be made of other materials such as steel, copper or zinc.

Roof slabs are usually installed by attaching them to the roof slab using nails or screws.

Aluminum roofing is a sheet of aluminum that is rolled into rolls and then flattened to the proper thickness. These sheets are cut into panels that can be installed on roofs as shingles or panels.

The benefit of aluminum roof panels is that they are light, durable and recyclable.

How do aluminum roof panels work?

Aluminum roof panels can be customized for any project. They can be cut to size and customized to different shapes and styles.

HWALU roofing panels are available in a variety of colors and profiles, such as round corrugated, trapezoidal and tiled, for aesthetic appeal and top quality.

Aluminum is a light-weight, strong, and easy-to-machine metal. Also affordable. These are the reasons why aluminum roofing panels are so popular.

Color Coated Aluminum Roof Sheets

One of the most important reasons to use an aluminum roof is its light weight. This means installers can easily use the material on their roofs, saving on installation costs.

Which aluminum sheet is the best roofing material?

Henan HWALU Industrial Co., Ltd. is a professional manufacturer of pre-coated aluminum roof panels. It uses a color coating production line to apply one or more layers of fluorocarbon/polyester paint on the surface of aluminum alloy through pretreatment, roller coating, baking and other processes. , It can also be painted with different patterns to make the decorative effect of the aluminum plate better.

The width of the aluminum plate used for the roof can reach 1850mm, and the specifications such as thickness and weight can be customized according to the engineering processing.

Step tile, aluminum roofing and corrugated aluminum roofing are our popular styles

Aluminum Roof Sheet Price

The price of aluminum roof panels depends on the surface coating used and the thickness of the aluminum panels.

The life expectancy of PVDF coating is more than 25 years, which is more expensive than PE coated aluminum sheet roofing. In addition, the thickness of the same roof panel is different, and the weight of the raw materials used is also different, and the thicker it is, the more expensive it is.

Production process of pre-coated aluminum roof panel

Pre-coated aluminum roofing coil This product adopts two-coating and two-bake production process.

HWALU Aluminum has two production lines for thick material coating such as solid color paint, wood grain, wire drawing, marble pattern and chameleon.

Aluminum plate pre-roll coating process

In order to ensure the coating quality of color coating products, oil, dust and rust on the surface of the substrate must be removed before painting.

This is the first step to ensure the coating process, and it is also the basic work to ensure the quality of the color-coated board products.

The purpose of the treatment is to remove the anti-rust oil, rust spots and dust attached to the surface of the substrate, and to chemically coat the surface of the clean substrate to increase the adhesion between the substrate and the coating and improve the corrosion resistance of the substrate. and coating durability.

Specification for Prepainted Aluminum Roof Slabs

Appearance quality inspection method of pre-coated aluminum roof panel

According to the provisions of GB/T9761, the test is carried out under natural light conditions that are not exposed to direct sunlight. Randomly select at least two samples from the same batch (total area not less than 1m2) and connect them side by side along the same production direction, and perform visual inspection at a distance of 3m from the center of the assembled board. The consistency of the sample production direction should be maintained during the test.

Those who take and place the samples do not participate in the visual inspection.

The color difference of single-color products shall be evaluated according to GB/T11186.2 and GB/T11186.3, and the visual inspection shall prevail for metallic paint and anodized film.
