One top surface category: inclined top type (pointed arc top type) structure composition: the facade adopts single glass plastic steel doors and windows (or double glass plastic steel doors and windows), and the top surface adopts color aluminum square tube frame combined with 8mm tempered glass (or 5 + 5 laminated glass, 5 + 5 single-sided tempered laminated glass, 5 + 5 double-sided tempered laminated glass).Planning features: high strength, long life, economical and applicable, suitable for steel structure with small span, etc. 

Top surface category: inclined top type (pointed arc roof type) structure composition: the facade adopts color aluminum window (or frame less balcony window), and the top surface adopts carbon steel square tube combined with 8mm tempered glass (or 5 + 5 laminated glass, 5 + 5 single-sided tempered laminated glass, 5 + 5 double-sided tempered laminated glass). 

Planning characteristics: high strength, long life, but need nominal solution, suitable for all kinds of steel structures. 

Three types of top surface: inclined roof type (pointed arc roof type) structure composition: stainless steel square tube is used for bracket, flow glass combined with frameless balcony window is used for facade (color aluminum window can also be used), and 8mm tempered glass (or 5 + 5 laminated glass, 5 + 5 single-sided tempered laminated glass, 5 + 5 double-sided tempered laminated glass) is adopted for the top surface.Planning features: high strength, long life, economical and applicable, but various colors, suitable for all kinds of steel structures.
