Randomly take at least two samples of the same batch (with a total area of not less than 1m2) and join them side by side in the same production direction, and visually inspect them 3m from the center of the assembled board. The consistency of the production direction of the sample should be maintained during the test.

Those who take and place samples will not participate in the visual test.

Monochrome products are evaluated for color difference in accordance with GB/T11186.2 and GB/T11186.3. Metal paint and anodized film are subject to visual observation.

Disadvantages of aluminium roofing sheets:

Roofing sheets have many benefits including being lightweight , ow price and recyclable.But there are also some downsides(disadvantages).

1. High cost aluminium roofing sheets

Aluminium is considered to be a much higher quality material compared to zinc or steel. This sets it at a higher price in the metal roof market.

Due to its durability compared to roofing materials such as tiles or asphalt shingles, it is also much more expensive to install. The way it is being setup can be different and hence require well-trained roofers.

2. Aluminium roofing sheets can be noisy

One main issue with aluminium roofing sheets and other types of metal roofs is that they can be noisy when it rains. Each heavy droplet of rain is like the stroke of a drumstick to the batterhead of the drum.

During heavy storms, they form a chaotic symphony of drumming that can be annoying to some people. An extra sheet of sound-proof material could be installed right underneath the aluminium roofing sheet to reduce the noise.

3. Aluminium is easier to dent

The characteristics of aluminium is that it is malleable. Malleable means that it can be hammered into a shape without cracking or breaking. While this may sound like a good feature that the aluminium sheet has, it might not be so when it comes to protecting your house from the elements.

4. Roof repair cost for aluminium roofing sheets can be higher

Aluminium roofing sheets are well, sheets of aluminium overlaid and arranged on each other. It is not like tile or asphalt shingles where one cracked or damaged shingle can be easily replaced with a new one. The same goes for other types of metal roofs. Different material may require different ways to fix the metal roof.

5. Poor fasteners installation could cause roof leak

Fastener is the screw that holds your roof onto the substrate or deck. Unfortunately, human error is one of the most common reasons for faulty fastener installation. These are potentially open spots on the roof that rainwater can seep in.

Pre coated aluminium roofing sheets Mortar Resistance Test Standard

• After mixing 75g of building quicklime powder conforming to JC/T 480 and fine sand in a ratio of 1:3, filter with a filter with a pore size of 0.84mm, add appropriate water to make a mortar, and apply it on the surface of the paint film.
  Paint it to a size of 50mm×25mm and a thickness of about 13mm.
• After placing the sample in an environment of 38℃±3℃ and relative humidity of 95%±5% for 24 hours, remove the mortar and wipe off the residual dust with a damp cloth.
  The residual ash that cannot be removed can be removed with a 10% hydrochloric acid solution, and visually inspect the appearance after drying.
• After the aluminum sheet is coated with fluorocarbon paint, various excellent properties such as high weather resistance, antistatic, anti-fading, high durability, preservative are added to make the aluminum plate more practical and durable.

Imitation copper, 3d wood grain effect, imitation wood grain, wooden, blue sky pattern, hemp pattern are well received by customers.

Aluminum roofing VS Steel roofing

Aluminum is more malleable than steel, allowing it be configured into more complex profiles. However, especially in simpler profiles, you need fairly heavy gauge aluminum and that will boost its cost.

Steel inherently has more strength than aluminum, it’s usually less expensive and it’s more fire resistant without underlayment. Aluminum does not have a Class A fire-rating but the system can achieve a Class A rating with the proper underlayment and sheathing.

Aluminum alloy has excellent corrosion resistance, aluminum roof has a longer service life than steel roof.

Aluminium roofing sheet price

Aluminium roofing sheet price depends on the surface coating used and the thickness of the aluminium sheet.

PVDF coating has a life expectancy of over 25 years and is more expensive than PE coated aluminium sheet roofing. In addition, the thickness of the same roofing sheet varies and so does the weight of the raw material used, the thicker it is the more expensive it will be.
