They each have their own emphasis, but I feel that Jianmei aluminum is better.
First, Jianmei Aluminum is a brand in Guangdong. It has developed and developed aluminum alloy profiles in more than 18,000 cross-section specifications, of which more than 100 series have obtained patented technology certification. In 2004, "Ivory White Aluminum Alloy Profile" passed the provincial technical achievement appraisal.
Second, Fenglu aluminum is also a brand in Guangdong. Fenglu has established a comprehensive range of products from mold design and manufacturing, casting, extrusion, oxidation coloring, electrophoretic painting, powder spraying, fluorocarbon paint spraying, heat insulation , polishing and dyeing, seamless pipes, finishing of doors and windows, and deep processing of aluminum profiles for transportation, aviation, and military industries. The product structure has realized a multi-field, comprehensive transformation and leap from architectural profiles to industrial profiles + military profiles + aerospace profiles + special aluminum alloy profiles.
Aluminum products are made of aluminum and other alloy elements. Usually, they are first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then are made through processes such as cold bending, sawing, drilling, assembly, and coloring. The main metal element is aluminum, with some alloying elements added to improve the performance of the aluminum material.
