Sometimes when people buy things, they will encounter great differences in the quality of the products they buy with the same money. This is due to the wrong understanding of the products. Just like when people buy color steel plates, they think that manufacturers use good paint and good raw materials, so they spend a lot of money to buy different quality, which is a wrong understanding of color steel plates. Many other products are more prone to this situation than color steel plates. When people buy things, they think that the packaged product or the product described by the merchant is moved by the raw materials, and they think that these products must be good. In fact, this is not the case. Good raw materials and packaging can be done by almost every manufacturer, but really good products are not necessarily good materials and packaging. It needs to include many aspects, and there are many requirements in the production process alone. To meet these requirements, we can get a really good swatch, not just a table. This is how many people spend the same money, but find that their color discs are very different from others and spend the same money. Some swatches will not fade and paint off after four or five years, and some paint will severely fall off after two or three years. At the time of purchase, manufacturers said they used good raw materials and achieved different results. However, Changzhou Dinggang makes people think that money is more valuable than money.

Hardness refers to the ability of a material to resist the pressing of a hard object into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the abrasion resistance. Common hardness indicators are Brinell hardness, Rockwell hardness, and Vickers hardness. Brinell hardness (HB) A certain load (generally 3000kg) is used to press a hardened steel ball of a certain size (generally 10mm in diameter) into the surface of the material for a period of time. After unloading, the ratio of the load to the indentation area is the Brinell hardness value ( HB). Rockwell hardness (HR) When HB> 450 or the sample is too small, the Brinell hardness test cannot be adopted and the Rockwell hardness measurement is used instead. It is a diamond cone with a vertex angle of 120 ° or a steel ball with a diameter of 1.59 / 3.18mm. It is pressed into the surface of the material under a certain load, and the hardness of the material is obtained from the depth of the indentation. According to the hardness of the test material, it is expressed in three different scales: HRA: It is a hardness obtained by using a 60kg load and a diamond cone indenter. It is used for extremely hard materials (such as cemented carbide). HRB: It is a hardened steel ball with a load of 100kg and a diameter of 1.58mm. The hardness is determined for materials with lower hardness (such as annealed steel and cast iron). HRC: It is a hardness obtained with a 150kg load and a diamond cone indenter. It is used for very hard materials (such as quenched steel). Vickers hardness (HV) The diamond square cone indenter with a load within 120kg and a vertex angle of 136 ° is pressed into the surface of the material. The surface area of the material indentation pit is divided by the load value to obtain the Vickers hardness value (HV).

Initially,the supplier admitted that was made by their mistake and they were willing to afford the refunds.Then,no matter what’s the way my client wanna to contact with the supplier,all be ignored.Calls been dropped,email were rejected.

Kynar 500 PVDF Coating   KYNAR 500 is fluropolymer resin used in paint formulations for exterior and interior metal finishes.The key to its durability and resistance performance is the carbon-fluorine bond,one of the strongest molecular bonds known.The resin has been proven to resist acid rain,erosion,airborne pollutants,dirt retention,ultraviolet light,and extreme temperatures.Finishes with KYNAR 500 based offers color uniformity and texture consistency over long periods of time.   The excellent outdoor aging and weathering properties of Kynar 500PVDF resin led to its use in long-lasting paints for coating metal sheet and extrusions for the past 50 years.Kynar Aquatecresins offer the same kind of extreme weather protection in waterborne paints for factory and field applied, low-VOC coatings.   Weatherability is excellent with little or no cracking,peeling,chalking or fading.The originator of fluoropolymer resins for architectural coating,Atochem North America,has been manufacturing KYNAR 500 resins since 1965.   KYNAR 500 based coatings are used on such architectural building materials such as roofing and siding,extrusions and panels,curtain walls and window frames,shop fronts and lighting fixtures,retail store interiors and louvers;ventilation parts and outdoor signage.   KYNAR 500 based finishes are used on many of the world’s monumental structures.Some notable architectural projects using KYNAR 500 based coatings include:Taj Mahal In Atlantic City,NJ;Mellon Bank Center and Liberty Place Complex in Philadelphia,PA.United States of America;the Skydome Toronto,Ontario;Canada and the Annex of the Louvre in Paris,France.   Kynar 500 resins may also be used to protect thermoplastics through coextrusion or film lamination techniques to obtain anti-grime and anti-graffiti surfaces with excellent weathering properties.   Dingang’s pre-painted aluminum products use the Kynar 500 pvdf coating.

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."
