Phenolic caster wheels are recommended for smooth concrete floors and can be used for storage loads without permanent compression set to the wheel. These phenolic wheels are highly resistant to oil, grease, gasoline and mild acids. Phenolic caster wheels will carry loads as great as the same size Gray Iron Wheel Casters. The wheel tread may show wear from repeated travel over rough floor surfaces. Phenolic Wheel Casters are one of the most commonly used casters due to the inexpensive costs and high weight capacities and durability these type of wheels offer. If your looking for a true heavy duty caster that wont break the budget buy phenolic wheel casters from CasterHQ. Phenolic Casters can be used in many industries and applications due to the durability and strength. These wheels can hold large amounts of weight, will not tear up concrete floors and will not flat spot. Phenolic wheels perform best on smooth surfaces due to the wheels hardness. Phenolic wheels do not perform well on un-even floors with chipped concrete or obstacles in the wheels path. Phenolic Wheels should NOT be exposed to water. The material of phenolic wheels will eventually swell and the wheel could fall apart over time if exposed to water. These should be used in clean, dry environments such as warehouses, garages, buildings, retail stores, and anywhere that has clean, dry floors. I would not recommend Phenolic floors on custom wood floors as these could leave slight indentions if the weight of the cart is too heavy since real hardwood is a naturally softer and expensive floor type.
