Plastic nylon double wheel aluminum door and window roller, African roller, positioning roller

Plastic – iron rollers are crafted for aluminum alloy door and window setups, harmonizing performance and cost – effectiveness. Composed of a nylon – based plastic (for low – friction sliding) and a coated iron core (for structural strength), they conform to frame contours easily. This design cuts down on friction – caused abrasion, extending the service life of doors and windows.

The plastic part, with its natural wear resistance, lowers sliding noise (≤30dB in operation) and resists moisture, dust, and mild corrosion—ideal for humid or dusty environments like bathrooms or basements. The rust – proof coated iron boosts load capacity (80 – 120kg), making it fit for home sliding doors, shopfronts, and basic commercial spaces.

Though not as light as full – aluminum rollers or as heavy – duty as all – iron models, they offer a budget – friendly answer to daily sliding needs. Surface treatments keep corrosion at bay, ensuring smooth sliding long – term. A top pick for value – focused projects, they provide reliable sliding for homes and small businesses.
