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."

Heat Insulation Steel Coil Advantages

Last days a heavy snow has visited our Changzhou City. In China it is very cold now. But to the contrary, the southern hemisphere countries and areas are in hot temperature. How to help people to work comfortably in hot areas, Bosses? Our Heat Insulation steel coil can help you.

By comparison testing of performance, the insulated effect of the factory building which used ‘Dingang’ insulation material can achieve 15 degree or more because the high reflectivity of the material surface metal layer.  Here are the normal specification customer uses.

Specification:
Thickness: 0.2-0.5mm
Width: 600-1250mm 
Length: Any Length 
Base Material: Pre-painted Steel Plate

If you know the advantages of the heat insulation steel coil, I think you will have the desire to buy our coils.


Acid and Alkali Resistance
In the acid properties, the use of anti-aging alloy metal film, the products of ‘dingang’ can reach twice effect than ordinary color coated coil products.

High Weather ability
The special metal alloy surface which passes the national building materials testing center of artificial aging test, the alloy layer maintains more than 82% reflectivity, and the anti-aging properties is superior to a-level standard.


Noise Reduction 
The metal composite layer surface effectively reduces the external noise. the noise insulation properties reduce 30db compared with pre-painted steel plate.

Useful Life
the useful life is more than 15 years in no ph environment, and life can reach more than 10 years at ph environment.
