Manufacturers Direct Sales Aluminum Alloy Door and Window Accessories Iron Roller Green Wheel

Iron rollers are engineered for heavy – duty door and window applications. Constructed from high – grade steel, they deliver exceptional load – bearing capacity (up to 300kg+ for some models), making them perfect for industrial settings like factory gates, warehouse sliding doors, and large – scale commercial fixtures.

The robust structure resists deformation under heavy loads, ensuring long – term stability. Surface treatments like galvanization or painting enhance rust resistance, prolonging service life in outdoor or humid environments. Though not as silent as plastic alternatives, their durability and strength make them indispensable for scenarios where security and load support take priority, such as industrial facilities and heavy – duty residential gates.
