1, the excellent advantage of German products is that the raw materials are very good, which can fundamentally guarantee the quality of products. At the same time, the production technology and design of doors and windows make doors and windows products have excellent heat insulation, sound insulation and noise reduction, which is very safe and durable. The disadvantage is that the product positioning is too high and the price is expensive.
2. Jing Lei is an excellent product with German technology. Its advantage is that 6063-T5 aviation grade Si-Ti-Mg-Al alloy is used as raw material, and its wall thickness is 1.8mm, which meets the national standard for aluminum alloy doors and windows. It is equipped with dual patented technology, integrated Vihagen hardware fittings, standard water-swellable EPDM rubber strip and many other high-quality designs. In a word, the price matching these configurations is very rare in the doors and windows of security systems on the market at present, and it is a well-deserved choice with super high cost performance. Disadvantages are low popularity and small audience among buyers.
