As an alternative to the macro high chrome aluminum ladder with advanced chemical treatment technology, high-chromium-free technology macro aluminum ladder is completely free of heavy metals, eliminating heavy metal pollution on the environment and toxic chromium slag containing chromium wastewater discharge. Since the first chromium-free treatment process can provide good adhesion and corrosion resistance, is now widely used in communications equipment, household appliances, such as auto mechanics and finishing industries. The relevant parameters of the traditional indicators of process wastewater chromium emissions to reach the national standard, the cost of the huge cost and waste of resources. Chromium-free production technology in a huge environmental social benefits, process parameters and quality control also has strict requirements. The process of quality testing process, there is a full range of testing standards and methods, better macro-high aluminum sub-platform lift factory was established in 2008, the company will be located in Henan Province - Zhengzhou City, is a professional production of aluminum ladders: Aluminum Alloy household ladder, aluminum household ladder, aluminum lift, aluminum multifunction ladder, aluminum bamboo ladder, aluminum lift platform, lifting platform, hand lifting platform, hydraulic lifting platform, ladder insulation, insulation ladder word insulation ladder extension ladder shrink and other manufacturers, good quality, excellent price! ! !
