Bulk Commercial Rubber Gym Flooring Rolls
These rolls are manufactured from recycled SBR (styrene‑butadiene rubber) blended with a controlled percentage of EPDM for UV stability. The compound is cured under precise temperature and pressure to achieve a uniform density throughout the thickness.
Typical roll widths are 1.22 m (4 ft) and lengths can be supplied up to 30 m per roll, allowing seamless coverage of large training areas with minimal seams.
Material Composition
The base rubber contains approximately 70 % SBR and 30 % EPDM by weight. Fillers include carbon black for reinforcement and calcium carbonate for cost balance. A small amount of processing oil (≤5 phr) improves mixing efficiency without compromising mechanical properties.
No phthalates or heavy metals are intentionally added; the formulation complies with REACH SVHC limits for indoor flooring.
Performance Specifications
| Property | Typical Value | Test Method |
|---|---|---|
| Thickness | 8 mm – 12 mm (customizable) | ISO 24346 |
| Density | 1.10 g/cm³ ±0.05 | ISO 845 |
| Shore A Hardness | 80 ± 5 | ISO 7619‑1 |
| Tensile Strength | ≥ 2.5 MPa | ISO 37 |
| Elongation at Break | ≥ 150 % | ISO 37 |
| Coefficient of Friction (wet) | 0.6 – 0.8 | ASTM F2913 |
Applications and Functional Fit
In weight‑lifting zones, the flooring absorbs impact energy from dropped barbells, reducing peak forces transmitted to the sub‑floor by up to 40 % compared with bare concrete. This protects both equipment and structural concrete from cracking.
For cardio and functional training areas, the surface provides a coefficient of friction that prevents slipping during lateral movements while still allowing smooth pivot transitions. The closed‑cell structure limits moisture absorption, which helps maintain dimensional stability in humid environments.
The material’s resistance to microbial growth makes it suitable for multipurpose facilities where cleaning regimens include disinfectants; laboratory testing shows <5 % weight loss after 30 days exposure to a 0.1 % quaternary ammonium solution.
Installation Considerations
Rolls are laid directly over a smooth, level substrate. A polyurethane‑based adhesive with a shore A hardness of 60 ± 5 is recommended for permanent installations; for temporary layouts, double‑sided carpet tape with a shear strength ≥ 1.2 kPa suffices.
Seams are sealed using a hot‑wedge welding tool that melts the rubber edges together, creating a continuous surface with tensile strength matching the base material. Expansion gaps of 3 mm per 10 m are accommodated by leaving a small clearance at perimeter walls.
Customization Options
- Thickness: 6 mm, 8 mm, 10 mm, 12 mm, 15 mm
- Color: Black, Dark Gray, Red, Blue, Custom Pantone matches
- Surface texture: Smooth, coin‑dot, ribbed (for added grip)
- Edge treatment: Straight, beveled, interlocking tongue‑and‑groove
- Backing: None, adhesive‑ready, or pre‑applied double‑sided tape
Quality Control Philosophy
Each batch undergoes inline rheometry to verify cure state; samples are taken every 30 minutes for tensile and hardness testing. Finished rolls are inspected for thickness variation using a laser profilometer, with acceptance criteria of ±0.5 mm across the width.
Visual inspection checks for surface defects such as blisters, foreign particles, or color streaks. Any roll exceeding a defect density of 2 mm² per linear meter is set aside for rework or scrap.
Packaging and Shipping
Rolls are wound onto a rigid cardboard core (inner diameter 150 mm) and wrapped in UV‑stable polyethylene film. The outer layer consists of a corrugated cardboard sleeve with corner protectors to prevent edge damage during handling.
Standard pallet configuration holds 20 rolls (approximately 24 m² each) stacked no higher than 1.2 m. Pallets are stretch‑wrapped and labeled with product code, batch number, and safety handling instructions.
Frequently Asked Questions
Can dimensions be customized? Yes, width, length, thickness, and color can be adjusted to match project specifications; tooling changes may affect lead time.
What information is required before quotation? Required data include total area, desired thickness, preferred color or texture, substrate type, and installation environment (indoor/outdoor, temperature range).
How is quality inspected? See the Quality Control section above; inspection reports are available upon request.
