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."

Why Chinese Commodity Prices Are Exploding--- Not Only Aluminum And Steel Products   Further to the second-last item above,China is once again a big story for resources. There was little heads up.But things have suddenly become very heated for commodities demand across China - as evidenced by the recent surge in zinc imports. And the thing is,it's not just zinc that's rising. This week,Beijing also called emergency meetings to discuss surging prices for steel.With benchmark Chinese steel prices having hit their highest level in 4 and 1/2 years this past week. More evidence?Chinese coal prices have been posting double-dight percentage gains the last few months-rocketing above $90 per tonne in recent weeks.A price that triggered officials to take emergency measures to cool the market. And it doesn't stop there.Chinese vanadium prices have doubled over the last month - and gasoline prices have been rising in recent weeks.Even prices for soymeal have soared. So waht's the uniting factor for these diverse commodities? The environment. Trades,analysts and government have all been citing once reason for the recent China commodities run: a crackdown currently underway on environmental compliance at industrial centers across the country. Sources say Beijing has launched the recent environmental push to clean up smog for the upcoming winter.With the government putting pressure on inspectors to shut down polluting factories,mines,and processing facilities by September. The focus is reportedly wide-ranging.With 28 cities across numerous provinces targeted for inspections. Regulators have promptly got down to business.Having conducted as many as three inspection sweeps already,and embarking on fourth round of checks imminently. Those inspections have had a major effect on production - for metals,energy and beyond.With reports suggesting that a majority of facilities in sectors like zinc have been shuttered while checks take place. The big question is: how many of those operations will eventually restart?With officials saying that many facilities inspected in sectors like gasoline refining and steel production don't currently meet basic emissions standards. Such extended closures would make the current rally in Chinese commodity prices more than temporary.And an extended run in Chinese prices will almost certainly put upward pressure on world rates - as demand rises for imports to fill the gap from declining domestic output. No one saw this coming. And it's unfolding very quickly.Watch the news out of China for details on how many facilities will be closed - temporarily and forever - and which commodities will get the biggest lifts in global demand.

Anodized Aluminum Product Introduction   Based on our area of expertise,we have always focused on the production of anodized aluminum coil using sulphuric acid in a continuous direct current process.Today,the coil is used wherever long-term stability and robust resistance are as important for surfaces as a decorative look.   Along with lighting and traditional decorative sector,it is now also the furniture,automobile,electronics and electrical industries that attach ever greater importance to such high-quality and non-sensitive surfaces.   Dingang offers a wide range of standard anodized surfaces.Their properties range from mat to bright reflective,recyclable,coloured,scratch-resistant,antistatic,paintable and sterilizable.This is complemented by multitude of surface structures.   Ask us for advice on the right choice of material.   Why aluminum? Control the light - impossible with white   Keep Control Keep control of the light distribution with aluminum surfaces! The directed light is important and effective for you illumination!Reflectance 85-98%. The reflector shape determines the light distribution!   Why anodized? Abrasion Resistance Test   Non Anodized Aluminum Untreated aluminum has a relatively soft surface that is susceptible to physical damage.Through natural formation of a thin layer of aluminum oxide,it loses some of its reflective properties over time (degradation of the total reflectance and specular reflection).   Thin Layer Anodized A relatively thin layer of aluminum oxide (200-400nm) may produce slightly higher degrees of reflectance;this type of anodized aluminum surface,however,is highly susceptible to damage.On the other hand,these material qualities are ideal for further coating using varnishing or primer systems.     Standard Anodized Adding a sufficiently thick layer of aluminum oxide in an anodising process,the surface is protected in the long term to maintain its properties.Used in typical applications indoors and in closed systems,the oxide layer is almost as hard as glass showing marked resistance to aging and wear for a surface with long-term stability.     Lose Control Lack of control due to the use of white painted (non metal) surfaces! The reflection will be mainly diffuse!Reflectance 85-97%. Only 4-6% of the light emitted by your light source can be controlled by the shape of the reflector!     Product Application I. Lighting: Such as grille lamp, lampshade, grille, diffuser of fluorescent lam II. Reflector plate of solar energy III. Exterior of construction IV. Interior decoration, such as aluminum buckle plate, ceiling, curtain wall V. Elevator VI. Nameplate, VII. The face panel of household appliance, microwave oven, refrigerator, etc.

Common Quality Problem Of Pre-painted Steel Product --- Wave Edge   Because of high mechanical strength,easy formation,excellent decorative and corrosion resistance,pre-painted steel products is very popular material in current world.In rapid developing industrial city,color coated steel material plays a vitally important role in the building constructions.   But many quality problems would occur during the production of pre-painted steel products.One of the common quality problems is wave edge.   And here has two different situations,one is born of base material itself,another is issued from the coating process.   The elongation of the other parts of the rolling roll in the middle or opposite sides is too large, which will generate waves, mainly because the roll crown does not match the rolling force, the bending roll is not adjusted well, the local cooling is not enough, and the plate has excessive convexity deviation. Etc.   The reason for wave edge of color coated steel is generally that the hot-dip galvanized sheet is not pulled and properly corrected by the tension correction, or the roller is broken, or the roller has unevenness in the production process of the color-coated plate, which is also called edge wave.How to solve the problem,perform secondary tensioning then shaping,that would be ok.   If after coating process of bulk production,it would be in futility with the subsequent roll flattening or other methods to solve the quality problem.   It’s very very important to choose a reliable and responsible supplier to purchasing agent in construction industry.     Changzhou Dingang Metal Material Co.,Ltd has been in the line for many years and is known as one of the leading exporters of pre-painted metal material in China,which own full automatic color coating production lines of steel products with output of 500,000 tons/year and six pre-painted aluminum production lines with output of 300,000 tons/year.   Many landmark construction building projects worldwide use our metal products as main body material.   Choose Dingang that is to choose high quality metal products.   CHANGZHOU DINGANG METAL MATERIAL CO.,LTD.
