Yes! Both Royal and Premium can cope with this. Jacks have different types of support leg. Some are “pointed”, others less so. When you lift heavy items, if the support legs are pointed (high point load), the flooring may react causing the plastic to whiten. However, this is only the case with certain sensitive colours. If you choose one of our grey shades, for instance, this cannot happen. As jacks look different, you can make certain you will not destroy the flooring by placing a block of wood or piece of checker plate under the jack.
