Specialize in manufacturing aluminum alloy door and window accessories door and window hinges heavy-duty four-hole

Door and window hinges are critical for stable, smooth rotation. Crafted from materials like stainless steel (for corrosion resistance), brass (for elegance), or galvanized iron (for affordability), they support door/window weight while enabling easy opening/closing.

Heavy – duty hinges handle large, solid wood doors or metal gates, while compact, decorative hinges suit interior doors and casement windows. Features like adjustable tension and silent bearings enhance user comfort, reducing squeaks and wear. In high – traffic areas (e.g., hotel lobbies, office entrances), durable hinges ensure long – term reliability, while in homes, decorative hinges add a touch of style to vintage or custom – designed doors.
