16mm Rubber Gym Mats | 3ft x 3ft (915mm) | Commercial Grade | EN 13893 Certified | Free Weights & CrossFit

Full Technical Specification

The 3ft × 3ft Format — The Commercial Gym Standard

The 915mm × 915mm large-format gym mat is the specification that commercial gym operators, leisure centres and professional training facilities use as their default for free-weight and training floors. The reason is simple: at 0.84m² per mat, you need far fewer mats to cover the same area as smaller tile formats, which means significantly fewer seams, a cleaner floor surface, faster installation and a more professional visual result.

Fewer seams means fewer edges to collect rubber dust, sweat and debris over time. A large-format mat floor stays cleaner, looks better and requires less maintenance under commercial daily use than a floor of small tiles. This is why commercial gym fit-out contractors specify the 3ft format for free-weight zones, dumbbell areas and PT studio floors as standard.

16mm — The All-Round Commercial Training Floor

At 16mm of high-density SBR rubber, these mats deliver the impact protection and anti-fatigue performance required for the full range of commercial gym activity:

• Dumbbells across the full commercial weight range
• Kettlebells, medicine balls and weighted carries
• Squat racks, power cages and rig anchor points
• Cable machines and functional trainers
• All cardio equipment including commercial-grade treadmills and rowing machines
• CrossFit and functional training circuits
• HIIT, plyometrics and box jumps
• Bodyweight training, yoga and stretch zones

The 16mm depth absorbs the impact of training activity, protects the subfloor from equipment dents and scratches, and provides the anti-fatigue cushioning that reduces lower limb fatigue during extended training sessions. The EN 13893 non-slip surface maintains grip through every training movement in both dry and high-sweat conditions.

Yellow or Black Ramp Edges — Your Choice

Matching 1m ramp edges are available in yellow and black, ordered via the variant selector above. Yellow ramp edges deliver the high-visibility floor edge marking required for safety compliance in commercial, public and institutional facilities — leisure centres, schools, universities and CrossFit boxes. Black ramp edges provide a clean, understated perimeter finish for private training spaces, PT studios and home gyms. Both create a safe, professional bevelled transition at every exposed mat edge, eliminating trip hazards and completing the installation to the standard commercial facilities require.

How Many Mats Do You Need?

Each mat covers 0.84m². Divide your room area in m² by 0.84 and round up, then add 10% for perimeter cuts.

Examples: 3m × 3m room = 9m² ÷ 0.84 = 10.7 → 12 mats. 5m × 4m room = 20m² ÷ 0.84 = 23.8 → 27 mats. For ramp edges: measure the total exposed perimeter length in metres and divide by 1m per edge length.

Installation — Clean, Fast, No Adhesive

1. Acclimatise: Leave mats flat in the room for 24 hours — ensures optimal flatness and consistent performance.
2. Prepare subfloor: Any clean, dry, level hard floor — concrete, screed, timber or existing hard floor.
3. Lay mats: Butt mats tightly edge-to-edge, working row by row from your straightest wall. The mat weight holds everything in position — no adhesive needed.
4. Cut perimeters: Utility knife or jigsaw for clean perimeter cuts at any angle.
5. Fit ramp edges: Install yellow or black ramp edges on all exposed mat perimeters for a safe, professional finish.

A two-person team can install 50m² in a single afternoon. No adhesive, no specialist tools, no trades required. The floor is ready to use immediately.
