Why Metal Roofing --- Metal VS Other Materials

Asphalt

Asphalt shingle is made of felt or fiberglass that is coated with tar and then covered with tiny stones that are literally glued onto the surface. Over time, the stones wear away, the shingles deteriorate, come apart, and the roof begins to leak.

Asphalt singles have an average replacement lifespan of 8-12 years. In this time frame Asphalt shingles:

· Lose granules

· Crack

· Attract moss

· Blow loose in the wind

· Hold snow and decay

· They even fall off their nails

· Begin to curl

· Are non-insulating

· Are combustible

· Are heavy in weight

· Wood shingles curl and warp

· Heavy tile products can be a hazard

Wood

A wood roof requires a tremendous amount of maintenance. So it’s expensive to keep up. Over time, decay accelerates, the roof becomes unsightly, and it eventually fails.

Clay

Clay or concrete roofing tiles have their own set of problems, which includes water intrusion due to their porous make up. The roofing tiles become cracked by moisture seeping through the pores during the freeze/thaw cycle. Once the tile is cracked, water damage can occur before the homeowner realizes there’s a problem.

Steel

When steel is exposed to the elements, it rusts. The steel deteriorates and flaky red granules appear in the affected area.
As you can see, a Classic aluminum roof is by far the smart choice.

Color Coated Aluminum for Food Packing Cans

More and more people choose aluminum can cover packed food. Why? Because its light weight, protective, recycled properties. Our Dingang Brand tank cover and pull-tab aluminum material are all made of the best of the domestic high quality aluminum such as southwest aluminum. And the main raw and auxiliary materials are all international famous brands.

To ensure that we can supply the best goods to customer, we adopt the roll coating technology even it is aluminum sheet instead of roll, we also coat first and then re-cut. This is to ensure the cleaning, coating uniform, film thickness uniformity as well as reduce wastage and reduce waste.

The common alloys of our stock are A5182/H19 and AA5052/H19. The typical thickness range is from 0.22mm to 0.50mm with width range 800-1500mm. With enough raw aluminum material stock 800-1000 tons for customer choosing, our production lead-time only needs 10 days. So we can ensure the quick shipment requirement of customer.

Why Aluminum Roofing?

Residential metal roofing has become one of the most progressive trends in the home improvements sector. Homeowners that have invested in upgrading their outdated asphalt shingles are benefiting from the long lasting rewards that only high quality aluminum roofing can offer.

With a proven performance expectation of 50+ years, homes that are protected by certified premium quality aluminum roofing also beautify their neighbourhoods. With their distinct architectural profiles and long lasting finishes, aluminum roofing enhances the look of every home and increases property value.

From a practical point of view, the well-known benefits of aluminum roofing are many.Energy efficiency by keeping homes cooler in summer months, fire resistance, elimination of mold growth, extreme weather resistance, no fee warranty transfers to all future homeowners, and recycled content of up to 95% are just some of the reasons why more and more people are making the switch for the last roof they will ever need.

Classic Products aluminum roofing systems outperform every other kind of roof because they were designed to do so. The first key is that Classic Products aluminum roofs are made of a top-quality aluminum. Aluminum is recognized worldwide as the best combination of strength and low weight: that’s why space and air vehicles use aluminum components. Also, aluminum naturally forms a barrier against oxidation, which means that a Classic Products aluminum roof will never rust.

Many aluminum roofing systems are batten mounted because of their inferior design. In other words, the design of the product requires it to be installed on battens. Battens for roofing companies that use them, are not really a good thing though they try to spin it that way. Battens for them are a necessary evil. Classic Products Aluminum Roofing Systems are directly attached to the roof decking on an elementary level and do not need problematic strapping or battens.

Aluminum Temper Is Important For Before Placing Order

As a professional color coated aluminum plate supplier, we always meet such customers who do not clearly know what temper they need to use for their products. So we need to help them to choose right tempers. Firstly we need to confirm with customer the product they will make by our aluminum coil. Different product should be used right aluminum temper. Now I would like to introduce the common used tempers for color coated aluminum plate?

In the aluminum plate model, the two or three Arabic numbers after H indicate the subdivision state of H. H indicates the work hardening temper. Some work hardening indicated by T instead of H means heat treatment temper. H1 refers to pure work hardening temper which applies to the temper with additional heat treatment but only after the completion of hardening to obtain the required strength. H2- is on behalf of the material temper. Not annealed temper, also as heat treatment temper.

For color coated aluminum plate, the most commonly alloy we use is A3003, and the related tempers are H14, H16, H18, H24, H26 and etc. HO means the lowest strength processed product by totally annealed. From 2 to 4, 6, and till to 8 is arranged from soft to hard. And the super hard temper is 9.

For example, H24, H2 is not annealed temper, 4 is refer to material’s physical hardness control technology. All in all, H24 is belonged to un-annealed and half hardness temper.

So friends, if you have any questions for the aluminum temper, just let me know. I will help you solve it. New Inquiry for Color coated aluminum plate, please contact us.

Laminated Mirror Aluminum Reflective Film

When I was cleaning my sample shelf, I saw some laminated mirror aluminum sheet sample can’t be used anymore. Laminated mirror aluminum sheet is different from polished mirror and Anodized mirror aluminum sheet. It is a kind of sheet by sticking a layer of high reflective vacuum zincification compound material to the base aluminum sheet. Why I mean the sample cannot be used? The reason is that the stick layer can be separated from the base metal easily. Another meaning is the long time of the sample caused the separation.

Then a question comes, how many years a laminated mirror aluminum sheet can be valid? At normal use environment, indoor approx 7 years, outdoor 2-3 years. In order to keep a longer useful life, we need to take below three points in minds.

1. We stick every coil or sheet with protect pvc film before the goods get customer in order to keep a beautiful surface.

2. We choose high quality compound material to stick the reflective surface and base material.

3. 86%reflectance for the mirror surface helps customer to get a better light effect.

Our company supplies 0.17-0.5mm A1060 and A3003 two kinds of laminated material. Tell me your interested specification, and I will show you our service.

Pre-painted Aluminum Wall against Pre-painted Steel Wall

When I passed by our factory, I saw the warehouse wall, it’s really not good by looking the rusty surface. Why so easy rusted? Because the material is pre-painted steel instead of pre-painted aluminum.

Compared with pre-painted steel wall, Pre-painted aluminum wall has so many advantages. Below are the three main points.

1. Light weight, good mechanical properties, easy to process

2. Low repair cost, durability.

3. Much more use life than steel

4. Recycling

Here is the normal specification we supply customers for wall or roof making.

Thickness: 0.6-1.2mm

Width: Less than 1500mm

Alloy: A3003/A3004/A5052/A5754

Paint coating thickness: 18um, 20um, 25um
