Hi-Temp Bumper Plates

Hi-Temp bumper plates are designed to be the same diameter as a standard 45-pound iron plate, regardless of their actual weight, to ensure the barbell loads safely and evenly. This 450mm diameter is an IWF standard, ensuring that when dropped, the rubber absorbs the impact rather than the metal barbell sleeve. This is crucial for protecting the barbell's inner bearings during Olympic lifts.

While you can deadlift with them, standard deadlift technique involves setting the bar down gently, so the heavy rubber bounce of Hi-Temp plates can be annoying. Because they are highly resilient, they tend to bounce quite high when dropped from the top of a deadlift. Many powerlifters prefer "deadlift plates" or calibrated steel plates which have zero bounce.

Hi-Temp plates are manufactured using thick, virgin rubber that is specifically formulated to withstand extreme impact and high temperatures. Unlike cheaper crumb rubber plates that can smell strong and degrade quickly, Hi-Temp uses a denser molded rubber. This dense construction ensures they maintain their shape even if left in a hot garage or outdoor gym environment.

No, Hi-Temp bumper plates are exclusively drilled with a 2-inch center hole to fit standard Olympic barbells. Trying to use them on a 1-inch standard barbell is impossible without an adapter, which is not recommended for heavy lifting. They are strictly designed for Olympic weightlifting setups where the barbell sleeves rotate.
