When choosing door and window hardware, safety and durability should be the primary considerations. Hinges are the core load-bearing components of doors and windows. For wooden doors, stainless steel hinges with a thickness of ≥3mm are recommended for their strong load-bearing capacity and to prevent door sagging. Casement window hinges should use dedicated sliding supports made of aluminum alloy or stainless steel to support the weight of the window and allow for adjustable opening angles. Lock selection should balance security and convenience. For entrance doors, a C-grade lock cylinder is recommended for high security. For interior doors, lever handle locks are convenient to operate. Sliding door rollers should be made of nylon or stainless steel for quiet operation and wear resistance. High-quality rollers have low rolling resistance, smooth sliding, and strong load-bearing capacity to prevent door jamming or detachment.
Furthermore, door and window sealing hardware (such as weatherstripping and anti-collision strips) should be made of silicone or EPDM for their elasticity, aging resistance, and enhanced sealing performance.
