Plastic Iron Roller

Ideal for aluminum roller doors/windows, these rollers combine plastic (nylon) and iron for optimal performance.Plastic minimizes friction/noise (≤30dB sliding) and resists corrosion, suiting humid/dusty spaces.Iron (coated for rust-proof) boosts load capacity (80-120kg), ensuring long-term durability.Low maintenance (no frequent lubrication), easy to install/replace, fits standard aluminum rails. Enhances door/window service life
