LINCO also offers heavy duty cast iron caster wheels for the most extreme and demanding jobs. Our heavy duty cast iron caster wheels are your best choice in caster wheels if you are looking to transport cargo greater than a ton. Due to their solid steel nature, cast iron caster wheels will not flex or flatten out under a heavy load so are guaranteed a constantly shaped wheel that will always roll smoothly and effortlessly. In fact, of all the varieties of caster wheels, cast iron caster wheels are the only type guaranteed to give you a fast starting and smooth roll regardless of any weight. Cart iron wheels are also preferred in extreme heat situations because they will not melt or warp. Industrial cast iron caster wheels are limited however to only flat surfaces and although they generally don't harm fine finished floors they do run a risk of doing so and should only be used on a smooth concrete or similar surface. LINCO offers a wide range of sizes, colors, and styles of cast iron caster wheels to complete any project or repair need.
