Will rolling a large fridge on this plank leave marks or grooves?

Hello Russ - thank you for your inquiry. During the installation process, it is suggested that you use caution when rolling large, heavy loads across the floor. (I've personally used pieces of the flooring cartons to roll the fridge onto while installing the planks / rows behind and where the fridge will be placed. Then carefully rolled the fridge into place.) Also used those large moving straps to help offset some of the weight while positioning the fridge into place. Moving the fridge in and out after the flooring has been installed should also be done with caution. Please make sure the floor is swept in front of the fridge so as not to scratch or gouge the flooring if there were any pieces of dirt or debris. Hope this helps answer your question. Thank You -
