Aluminum Alloy Sunroom Series

Dongcheng's aluminum alloy sunroom series transforms outdoor courtyards, terraces, and garden spaces into fully functional, year-round living areas. Main frames are constructed from heavy-gauge aluminum profiles that have been treated for weather resistance, enabling the structure to withstand prolonged sun exposure, heavy rainfall, strong winds, and seasonal temperature extremes without warping or corroding.

A broad selection of roof forms — flat, arched, A-frame, pyramid, dome, and bespoke irregular geometries — allows each sunroom to complement its surrounding architecture while meeting specific load and drainage requirements. Glazing options include high-transparency tempered glass, laminated safety glass, and smart electrochromic glass, with optional integration of motorized shading, ventilation windows, and intelligent climate control systems.

Each sunroom is custom-built to the client's site dimensions and functional brief, with full-service design, fabrication, and installation support from Dongcheng. The result is a seamless extension of indoor living space that maximizes natural light while delivering the comfort, privacy, and protection of an enclosed room.
