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.

Anodized Aluminum Technology Applied To IphoneX   Easy to broken,tearing and heavy defects,that make Apple Inc abandon the use of glass material as the backboard of iphone.Apple Inc had started to put forth to apply metalwork as phone body material from Iphone 6 series. Combination the exposed photos,here’s no any doubt iphone 8 would continue all body metal material design idea.In additional,more and more mobile phone manufacturer choose to join into the camp.We can expect that metal body is the trend of global phone industry future development. So far anodized aluminum is one of the most advanced metal material.     What’s anodic oxidation?More generally,it’s the process to plate a compact oxidation layer on the surface of aluminum alloy that can avoid aluminum alloy further oxidation.At meanwhile,the aluminum and its alloy electrolysis coloration are important method to the aluminum surface protection and cosmetic processing. Compared with stainless steel and aluminum magnesium alloy,the anodized aluminum have the advantages as following:stable coloring,high strength,strong corrosion resistance,fingerprint-proof and excellent heat conduction performance.     Specifications Of Anodized Mirror Aluminum Thickness 0.3-1.5mm Width 1250mm Alloy 1085 Temper H18 Reflective Rate 85%-87% Form Of Supply Coil Or Sheet Notes: Products With Protective Film Are Guaranteed For 12 Months, Please Kept Away From Sunlight And Any Heating Source.   Typical Mechanical Properties: Tensile Strength ≥140N/Mm² Yield Strength ≥120N/Mm² Elongation ≥1% Minimum Bend Radii N/A Tolerance Thickness: ±0.02mm, Width: ±2mm         CHANGZHOU DINGANG METAL MATERIAL CO.,LTD.

The influence of U.S. unilateral trade protection policy   “Pull back from the brink” is the stern advice China gave to the US administration after Donald Trump signed an executive memorandum on Thursday imposing restrictive tariffs of up to $60 billion on Chinese imports and restricting Chinese investments in the US.   China’s initial response, although measured, signals the escalation of a trade dispute triggered by the protectionist-minded US administration prone to taking unilateral decisions. The Chinese embassy in Washington warned that “China would fight to the end to defend its own legitimate interests with all necessary measures”.   That China’s reciprocal measures will be taken in two stages leaves room for further negotiation and dialogue to resolve the trade disputes between the world’s two largest economies, in order to avoid a trade war, which would disrupt the on-going recovery of the global economy.   “China doesn’t hope to be in a trade war, but is not afraid of engaging in one,” the Ministry of Commerce said in a statement. “China hopes the United States will pull back from the brink … and avoid dragging bilateral trade relations to a dangerous place.”   Washington would do good to heed Beijing’s advice, because a trade war would hurt China, but not leave the US unscathed if China retaliates. According to economists’ calculation, a trade war may slow down US economic growth, raise consumer goods prices, and increase unemployment, especially in the Rust Belt, contrary to Trump’s claim that American jobs would be protected because of trade actions against China.   According to a University of Pennsylvania study, a full-blown trade war would, over time, offset any gains of economic growth from the US’ newly implemented tax cuts; it would also eliminate a year’s worth of wage growth.   By taking punitive trade measures under the outdated Section 301 of the US Trade Act of 1974 against its major trade partner on the pretext that “unfair” trade activities have hurt US interests, the Trump administration may be hoping to woo voters in the mid-term election this year. But when voters realize that, instead of being protected, their interests have been undermined, Trump’s stratagem will backfire.   Trump cannot lower the US’ colossal trade deficits with its major trade partners by imposing higher tariffs on imports, since the root cause of the problem is the ultra-low savings rates of Americans and the international division of labor. For Trump, it is easier to blame other countries for the US’ problems and garner votes in the mid-term election, instead of taking the pain to restructure the country’s economy. He cannot force China to give in, however, because China knows the US’ demands are insatiable.   Trade disputes should be resolved through discussions and negotiations under the framework of the World Trade Organization, not by unilaterally imposing tariffs.   Unilateral and protectionist moves usually lead to tit-for-tat trade retaliations, which today will disrupt the global trade and economic growth. But during his 14 months in office, the US president has cared little for multilateral trade.   Perhaps it’s time to remind Trump that in the early years of the 20th century, the US initiated protectionist trade measures to protect its domestic industries, forcing its trade partners to take similar measures, which resulted in a sharp contraction of global trade and economic growth. History does not repeat itself but only if we learn the right lesson from it.   By imposing harsh and unjustified restrictive tariffs on its trade partners, the US risks dragging the world into another destructive trade war, whose fires will also scald the US.
