While many residential doors eventually sag or draft, Susheng aluminium casement doors uses thick-walled, structural-grade aluminum profiles reinforced at the corners with heavy-duty internal cleats. This ensures the frame stays perfectly square, even when supporting large, heavy panes of double-tempered glass. The hardware is a deliberate upgrade, rather than standard hinges, they utilize friction-resistant, high-load bearings that allow the door to swing with a smooth, hydraulic-like feel. When closed, the multi-point locking system engages at several heights along the aluminum casement door frame, pulling the door tight against pressurized EPDM gaskets. This creates a perfect seal that effectively shuts out street noise, driving rain, and dust.

 

Susheng avoids the clunky, thick sightlines of traditional doors in favor of a slim-frame aesthetic that maximizes the glass surface. The aluminum is treated with a high-performance fluorocarbon or powder finish, which is far more resilient against UV rays and scratches than standard paint. This means the deep charcoal or bronze tones won't peel or fade after a few summers in the sun.  Whether used as a grand entrance or a side terrace door, these aluminium swing doors are for superior security, soundproofing, and weather resistance in modern commercial and residential projects.
