Traditional metal casters were once the preferred choice for heavy-duty applications, but their side effects are increasingly evident:
Direct Physical Damage:Hard metal edges can directly cut and scratch soft floor paint surfaces, while heavy loads may cause permanent indentations, compromising the structural integrity.
Secondary Pollution:Metal wheels may generate metal chips or dust during operation, causing contamination that is difficult to remove from products and the environment. This is unacceptable for production environments that demand purity.

Polyurethane wheels : Softness, Cleanliness, and Durability in One
Compared to metal materials, high-performance polyurethane wheel offers revolutionary advantages for floor protection:
Non-Damaging Contact, Ultimate Care:The inherent flexibility of polyurethane material allows it to contact the floor like a "soft cushion," dispersing pressure effectively to prevent scratches and indentations, significantly extending the service life of high-end flooring.
Mark-Free Operation, Cleanliness Guaranteed:Polyurethane casters using special non-carbon black formulations fundamentally eliminate the stubborn black marks often left by traditional black rubber wheels. This characteristic makes them an ideal choice for venues with stringent cleanliness requirements, perfectly serving:
Food and Pharmaceutical Industries:Meeting GMP standards to ensure absolute cleanliness in production environments.
Electronics Cleanrooms:Preventing micro-dust contamination to safeguard precision manufacturing.
Logistics Warehouses and Commercial Centers:Maintaining floor cleanliness and appearance, enhancing environmental quality and safety.
Industry Outlook
As companies place increasing importance on workplace safety, production cleanliness, and asset maintenance costs, polyurethane casters—which combine high load capacity with floor protection—are transitioning from "optional accessories" to "essential configurations." The widespread adoption and application of this technology signify that industrial equipment components are evolving towards smarter, more friendly, and more sustainable directions.
