GB/T 5237 Aluminum Lead The Healthy Development Of Aluminum Industry
Apr 11, 2018


In recent years, GB/T 5237 standard aluminum profiles rely on its solid surface treatment technology foundation, providing solid technical support for the expansion of aluminum products, and promoting the building structure (template, overpass), furniture (closet, table, bathroom, pendulum) Put items racks), home appliances (kitchenware, TV frames, washing machines, radiators, refrigerators, stereos, rice cookers, digital products), interior decoration (aircraft, automobiles, boats, rail transit interior decoration), transportation (aluminum alloy half The rapid development of the surface treatment aluminum manufacturing industry in areas such as trailers, functional materials (solar frame, LED shades), etc., has driven aluminum consumption by millions of tons.

Aluminum GB/T 5237 series of standards have high precision manufacturing GB/T 5237.1 substrate standard, multi-color anodized coloring GB/T 5237.2 anodized profile standard, high salt corrosion GB/T 5237.3 electrophoretic coating profile standards , Environment-friendly color GB/T 5237.4 spray profile standards, high weather resistance GB/T 5237.5 spray profiles standards, energy-efficient GB/T 5237.6 heat insulation profile standards. With continuous revision in recent years, GB/T 5237 profiles are rich in product types, beautiful in appearance and excellent in performance. They are recognized by many industries at home and abroad, and they are also promoting the extension of aluminum industry and market expansion, and assisting the aluminum industry in solving excess capacity. Other areas have created indelible credit. It is reported that in 2016 China's annual output of this series of products reached 15 million tons.

According to statistics, at the end of 2013, China's aluminum alloy templates accounted for less than 1% of the building formwork timber, and by the end of 2016, the proportion of aluminum alloy building profiles used in aluminum alloy building templates in all countries had reached 10%. The consumption of aluminum consumes 2 million tons, and aluminum alloy profiles for furniture pull about 500,000 tons of aluminum consumption.

At the same time, the English version of GB/T 5237 is based on its high international influence (GB/T 5237.2-GB/T 5237.5 has been quoted by ISO DTS 16688) in countries and regions such as the United States, Europe, and the “Belt and Road”. Leading China's aluminum alloy building profile products to achieve sustained and stable exports. It is reported that in 2016, China exported 1.18 million tons of aluminum extrusion materials, and 50% of imported aluminum alloy building profiles in ASEAN, West Asia, and other countries were from China.

This year's newly revised GB/T 5237 series of standards incorporates newer technologies for environmental protection, energy saving and emission reduction, and limits toxic and harmful components in surface treatment reagents. It is recommended that dust-free profiles be made of chromium-free materials that are harmless to human health. Treatment process, and increase the heat transfer coefficient heat transfer coefficient requirements. If the new standard is promoted and used, the production of 11 billion square meters of building doors and windows can save 430 million tons of standard coal annually, accounting for about 20% of the country's annual coal consumption.

The new GB/T 5237 standard will lead the transformation and upgrading of the related surface treatment aluminum manufacturing industry to the green and energy-saving direction, lead the healthy development of the aluminum industry, and continue to act as a structural reform on the supply side and a new normal economic restructuring in China. Resolve the vanguard of electrolytic aluminum excess capacity.
