Heavy-duty metal trolley wheels from Xiamen Yirong Hardware Co., Ltd. are engineered for extreme strength and durability, designed to withstand the toughest industrial conditions. These wheels feature a metal core—often steel or cast iron—with a rugged tread (either solid metal or coated in wear-resistant materials like rubber or polyurethane) to handle heavy loads and rough surfaces. The metal construction ensures exceptional load-bearing capacity, making them suitable for transporting large machinery, construction materials, or industrial equipment. Resistant to impact, high temperatures, and corrosion (with optional coatings), they perform reliably in outdoor or harsh indoor environments. Paired with reinforced metal brackets, these wheels provide stability and longevity, ideal for heavy-duty carts in construction sites, foundries, and industrial warehouses.
