Materials: The Advantages of a Metal Roof

Are you interested in making your house more energy efficient, adding a beautiful and striking major design element, and never having to replace your roof again? Consider a metal roof. While the cost of a metal roof is significantly higher than a shingled roof, it will likely last a lifetime and it is practically maintenance-free. The practical advantages of a metal roof are that it makes your home safer in harsh weather and can significantly cut down on your energy bills. Aesthetically, a metal roof is versatile in design to complement many architectural styles, from a century old farmhouse to a contemporary home.

Why did person choose metal? "They look great! Very crisp and architectural and much easier to get excited about than asphalt shingles. Other than copper and slate, both very expensive, enameled standing seam roofs have the best longevity. From a long-term maintenance standpoint this is a plus. Additionally, standing seam can be used on low-pitched roofs, where shingles would not be appropriate. We use this material very frequently on porches and dormers, which tend to have lower pitches. Finally, there are some nice color options."

However, there is a big drawback to using standing seam roofing for areas with harsh winter weather. "It sheds snow, leading to big piles of snow along eave sides and at valleys," Smith warns. "This needs to be taken into consideration when locating entries, walks, and plantings. When we do use standing seam for an entire house, such as this lake house in Vermont, we design to accommodate the snow issues and warn our clients!"

Architect Kenny Craft, who specializes in sustainable design, says "I am a big advocate for metal roofing. Because of the light color and reflectance, it helps to reduce heat build up in attics and finished rooms tucked into the roof. Metal roofing is also generally made from recycled content, and then, after its life, is itself recyclable."

Craft chose a corrugated metal roof here, because it has a long history of being used in Colorado and adds to the vernacular-inspired style of this new home.

Another attribute of metal roofing Craft appreciates is that, "it lends itself well to rain water harvesting. With its smooth clean surface, less filtering is required of water from a metal roof, compared to asphalt shingles which shed small particles, and possibly other chemicals."

Craft is also a big fan of indigenous architecture. Regarding the aesthetics of a metal roof he says, "the metal roof has a distinctive and authentic look; it's a material that is what it is — a rarity in today's world of composite look-a-likes — including asphalt shingles. The silvery galvanized color adds a fresh, timeless yet contemporary character to a dominate element of the composition."

Aluminum Sheet Storage & Packaging

At Dingang, we take great care for storage as well as packaging so that you can get your product protected from all expected hazards. All aluminum sheets are protected with 80-micron light density polythene film that adhered to the surface of the coated panel using high-quality water based glue. Our dedicated and efficient members of QC and Production Managers have all the necessary experience to determine which strength of the glue is best suitable for a particular production. We believe in delivering the product in right shape and thus not compromise on its packaging and maintenance.

Packaging and Palleting

The panel sheets are fully protected on all sides with wooden framework and steel trappings to protect them from any damage while there transit from company’s factory to the customer’s final destination.

Forklifts are used to move the pallets around.

Plywood is put on the bottom as a base plate for the attack and the height of these stacks are not more than 6 meters.

All the panel sheets are properly labelled with the relevant description like size, color, quality and project name etc for easy identification at the customer’s final destination.

All the pallets are placed in horizontal racks and extra care is taken when storing the pallets to prevent them from being exposed to the sun, rain, moisture and other elements.

If there are certain laws and regulations in certain destination then it is necessary that the customer must acquaint the company about them at the time of confirming their order so that the necessary arrangements can be made by the company in advance to avoid any delays due to non compliance.

When stacking panel sheets on the top off each other great care is taken so that nothing is placed between them to avoid causing any marks, dents , impression on any of the panel’s surface.

Corten steel- A Kind of Elegant

When we go to park, we often see some landscapes with a unique rusty texture. The color and texture are very strong. And the cold appearance and the surrounding environment are integrated which presents an industrial and modern art beauty. It is corten steel. It is unique because it is exposed to the natural environment and as time goes on, the surface will form an anticorrosion protective layer. No need the paint protection, the life of the material will be over 80 uears.

Difference

Corten steel is a kind of low alloy steel between ordinary steel and stainless steel series. by carbon steel adding small amounts of copper, nickel and other corrosion resistant elements, it has the high quality steel toughness, plastic drawing, forming, welding, abrasion, high temperature, fatigue resistance, and etc. The weather ability is 2~8 times of carbon steel, and the coating is 1.5~10 times of carbon steel. At the same time, it has the characteristics of corrosion resistance, anti - corrosion, attenuation, energy saving and so on.

I don't think most of the clients should understand the properties of the corten steel. Actually, it's not the red rust color when client get the plates on hands. The rust steel initially is roughly the same color as ordinary steel. Just because the rusty steel plate under the action of climate to form a protective film and not rust deeper into the metal, so it shows a retro rust effect.

Then we will tell the work engineer the wanted sizes and patterns, the engineer will carve the corten steel according to the provided size. After the 2-5 days rust process in approx 20 ℃, we will carve up the corten steel with design patterns by lazing technology.

See this, elegant, right?

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.

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.
