4' x 6' x 3/4" Colored Heavy-Duty Rubber Gym Matting - Our 10% fleck heavy-duty gym mats are basically short deadlifting mats with a splash of color. If you don't have the room in your garage gym or facility for full sized 4' x 8' x 3/4" deadlifting mats then these may be perfect. Constructed from solid crumb rubber, our 3/4" mats are made to absorb the heaviest impact and shock created from heavy weights including kettlebells, barbells and dumbbells. Each mat features a non-porous, slip-resistant top and wire-mesh bottom to help grip the floor.

3/4" Thick Rubber Mats are Ideal for Deadlifting and other Olympic Lifts - With 3/4" thick mats you'll never worry about sufficient impact protection for your floors and equipment. 3/4" rubber mats are the thickest Olympic weight lifting mats available. Use under power racks, underneath weight benches or as a stand-along mat out on the floor for performing deadlifts. Enjoy the versatility this product brings to your facility with no limitations.

Using multiple 4' x 6' x 3/4" rubber mats to cover an entire floor:
For complete floor protection under your free weight and cardio equipment areas, heavy duty recycled rubber gym equipment mats will do the job and then some. And since the mats are so big and heavy there is no need to use adhesive. Normally during the manufacturing process block mats are cut by hand, and are not always going to be exact dimensions in length and width, or have edges that are totally squared. In the case of a single mat or only a few mats, this is not generally noticeable. However, when multiple mats are laid side-by-side and end-to-end across a gym floor, the end user may experience gaps here and there resulting from less precisely cut edges being positioned next to each other. These gaps can trap dust and dirt, and in general create a less than ideal visual appearance. In many livestock and other industrial applications where function outweighs aesthetics (such as horse stalls and machine shops) this does not matter. However, in a fitness setting (such as a crossfit box, commercial fitness center, or military base gym) where 4' x 6' or even 4' x 8' block mats are utilized as "jumbo" loose-lay tiles to cover a large surface area of flooring, a more finished look is often desired. In this bulk purchase scenario it is recommended to have the mats "trued" to consistent size during manufacturing. The process of “truing” via sonic cutting puts the mats through a very precise method of production for straight, sharp edges and square corners, allowing exact consistency from mat to mat greatly reducing visible gaps and any other seam inconsistencies when installed. When requesting your flooring quote, let your IRON COMPANY® flooring sales rep know if your mats need to be trued.

Truing Upcharge: $3.00 per mat

Truing Lead Time: Please allow up to 4 weeks truing lead time prior to shipping since mats need to be custom produced to order and put through sonic cutting process

Shims are also recommended for larger installations to even out any height variances.
