Shandong Envi Doors and Windows Co., Ltd. - A Premier Industrial Hub for High-Performance Aluminum Fenestration Engineering.
Shandong Envi Doors and Windows Co., Ltd. was established in 2014. It is a large-scale comprehensive Aluminum Door and window enterprise that integrates design, production, and sales services. It is a large-scale comprehensive aluminum profile enterprise engaged in development, design, and production. It has reached a relatively advanced level in the production of building aluminum profiles, decorative aluminum profiles, and industrial aluminum profiles, and has its own door and window business unit. The company was founded in 1993. After years of unremitting efforts and development, the company's scale has continued to grow. The factory covers an area of 100,000 square meters and has modern advanced aluminum extrusion production lines. Its products are sold to multiple cities and regions in China. The annual designed production capacity of aluminum profiles is about 50,000 tons, with an output value of about 1 billion yuan.
The company has strong strength, adopts internationally advanced technology, and has a high degree of automation. It has multiple advanced aluminum profile extrusion equipment ranging from 600 tons to 2500 tons, two anodizing lines, two electrophoretic coating lines, one thousand ton color powder spraying profile production line, one threading line, one glue injection production line, one simulated wood grain production line, as well as a batch of advanced door and window processing equipment and deep processing equipment in the Yalian door and window production workshop. For the past 10 years, we have served over 1,500 projects in more than 100 countries and regions, All of our products meet international quality standards and are highly appreciated by different markets around the world.
From raw metallurgical ingot selection to computerized CNC milling, our multi-stage quality assurance protocol ensures zero-defect manufacturing for architectural door systems.
