Not necessarily. Belts with identical dimensions may differ in steel cord construction, coating properties, mechanical performance, and approved applications. The original equipment specifications must be verified.
Q2: What can cause cracks in elevator steel belt coatings?
Possible causes include material aging, repeated bending, environmental exposure, or abnormal mechanical conditions. The actual cause cannot be determined from surface appearance alone.
Q3: Does visible coating damage mean an elevator steel belt must be replaced?
Visible damage requires professional inspection. Replacement decisions should follow the elevator and belt manufacturers inspection criteria and applicable safety requirements.

Check the original part number, belt dimensions, construction specifications, elevator model, and required length. Photos of belt markings can help identify the product.
