Firstly, the assembly technical requirements and characteristics of bridge cut casement windows and ordinary doors and windows: Bridge cut aluminum doors and windows are cut into a 45 degree angle through a wall thickness of 1.4mm or more, and a complete set of equipment is assembled through doors and windows using specialized inserts of 3mm or more at the corners. Squeeze positioning, while ordinary doors and windows are made of about 1mm ordinary angle aluminum connected with rivets, which has poor firmness and completeness, but low cost. And the assembled broken bridge aluminum doors and windows will not be a problem for people to stand and walk on. The technical requirements for assembling complete sets of equipment differ greatly from those for manual on-site operation. Dedicated bridge cutoff aluminum profiles cannot be compared to regular aluminum profiles.

Secondly, the broken bridge casement window must be customized by aluminum manufacturers according to their production cycle. Its surface color treatment is standardized and technical, and its service life is long-lasting. Ordinary doors and windows are only made of any type of ordinary aluminum material, and they are not coated with the desired color without standardized treatment. Technical treatment is not in place by aluminum manufacturers, and the coating effect and service life will not be too good. Over time, there will be color fading and fading phenomenon, known as cowhide gland, Thus, it is determined that the production cycle of bridge-cut aluminum doors and windows is long, while the production cycle of ordinary aluminum doors and windows is short.

Furthermore, the design of the broken bridge casement window is different from that of ordinary doors and windows. The design pattern of the broken bridge is atmospheric, with transparent lighting, and is designed according to different spaces, with different characteristics.
