Cast Iron

As a professional industrial caster manufacturer, AstraRoll produces heavy‑duty cast iron casters and cast iron rigid casters, engineered for extreme‑load, high‑impact industrial applications where maximum strength and durability are required. Made from high‑grade solid cast iron, these casters deliver superior load‑bearing capacity, abrasion resistance and structural stability, far outperforming standard rubber, PU or nylon wheels in harsh heavy‑industry environments. Widely used for heavy machinery bases, steel‑workshop trolleys, foundry equipment, cargo transport platforms and factory heavy‑load mobile devices, they provide long‑lasting rigid mobility under continuous heavy‑load operation.

Cast iron wheels feature high density and rigid structure, resisting heavy pressure, sharp metal debris, high temperature and severe wear. Our cast iron rigid casters adopt fixed‑direction rigid bracket design, focusing on stable straight‑line transport for heavy‑duty equipment that does not require flexible steering. We also offer swivel‑type cast iron casters as optional configurations, with multiple mounting methods including top‑plate, bolt‑hole and stem mount, fully customizable for wheel size, load capacity and surface treatment to meet heavy‑industry working standards.

Core Product Range

Standard Cast Iron Rigid Casters
Solid one‑piece cast iron wheels paired with heavy‑duty rigid steel brackets, designed for stable linear movement. Ideal for medium‑heavy‑load trolleys, warehouse heavy‑storage racks and general industrial heavy‑transport equipment.

Ultra‑Heavy‑Duty Cast Iron Casters
Thickened large‑diameter cast iron wheels and reinforced welded brackets, supporting ultra‑high static and dynamic loads. Suitable for large machinery bases, steel‑plant transport carts, foundry equipment and heavy‑duty factory mobile platforms.

Heat‑Resistant Cast Iron Casters
High‑temperature‑treated cast iron material with anti‑oxidation surface processing, resisting heat radiation and high‑temperature environments in heat‑treatment workshops, furnaces and metal‑processing plants.

Key Features & Product Advantages

Ultra‑High Heavy‑Load Bearing Capacity
Solid cast iron material has extremely high compressive strength, capable of bearing tons‑level heavy loads without wheel deformation, cracking or sinking, perfectly matching heavy‑industry transportation demands.

Extreme Wear & Impact Resistance
Hard cast iron surface resists grinding from rough concrete floors, metal scraps and industrial debris, with excellent impact resistance against heavy‑load bumps and collisions, greatly extending service life.

High‑Temperature & Harsh‑Environment Adaptability
Cast iron wheels work stably in high‑temperature, oily, dusty and metal‑processing environments, not melting or softening like plastic wheels, and resisting corrosion from common industrial pollutants.

Stable Rigid Movement
Rigid bracket structure ensures straight‑line movement without deflection or shaking, improving transport stability and safety for heavy‑duty cargo and equipment.

Flexible Customization Options
Customize wheel diameter, bracket thickness, mounting hole position and surface treatment. Support zinc‑plating, painting and black‑oxide treatment to meet different anti‑rust and industrial‑grade requirements.

Typical Applications

Heavy‑duty industrial transport trolleys and cargo platforms
Steel mills, foundries and metal‑processing workshop equipment
Large‑scale machinery bases and heavy‑load mobile racks
Warehouse heavy‑goods storage and logistics transport carts
Heat‑treatment workshops, furnace‑side mobile devices
Construction heavy‑duty mobile equipment and engineering trolleys
