The surface construction makes these solid nitrile rubber mats well-suited for automotive repair shops, aerospace manufacturing, and machine shops where rolling equipment is common.
Unlike drainage-style mats, the continuous top surface provides a smooth rolling path for pallet jacks, tool carts, and wheeled equipment, including smaller casters that can experience vibration and resistance on open-grid designs. This makes the interlocking solid rubber mats effective in areas with frequent material handling and cart movement.
Manufactured from nitrile butadiene rubber (NBR), these nitrile rubber floor tiles offer chemical resistance comparable to that used in automotive fuel hoses and aerospace sealing applications.
The NBR compound withstands petroleum-based oils, diesel fuel, hydraulic and transmission fluids, brake fluids, animal fats, and common industrial solvents. It also maintains performance of these rubber floor tiles when exposed to kerosene, grease, and cutting fluids that typically degrade standard rubber materials.
The patented LockSafe connecting system features male and female interlocking profiles that snap together securely. Assembled sections can be rolled up as a single unit for cleaning and repositioned without reconnecting individual tiles. For custom layouts, these rubber anti fatigue mats can be cut in 12-inch increments without compromising interlock performance.
Optionally, 3" × 36" ramp edges are available in black or safety yellow with male and female connections to support visible, smooth transitions.

Q: What does NBR stand for?
A: GR stands for Grease Resistant.
Q: What types of fluids is the NBR compound resistant to?
A: The GR compound is best suited for areas with water and dry debris. It is also resistant to boric acid & ethylene glycol.
Q: What does NBR stand for?
A: NBR stands for Nitrile Rubber.
Q: What types of fluids is the NBR compound resistant to?
A: The NBR compound is resistant to silicone-based brake fluid, boric acid, ethylene glycol, animal fats, brake fluid, chlorine solution, diesel oil, petroleum-based hydraulic oil, salt water and vegetable oil.
Q:Does the 24/Seven LockSafe come with edge ramps or borders?
A: Yes, 3" edging is available in both yellow and black for 24/Seven LockSafe. Edging comes in both male and female to correspond with the male or female side of the mat. Edging comes in 3" wide by 36" long strips.
Q: Can 24/Seven LockSafe mats be exposed to liquids?
A: Yes, 24/Seven LockSafe mats can be placed in both wet and dry environments.
Q: How do I clean 24/Seven LockSafe?
A: Use a high-pressure hose (not to exceed 500 psi) and hot water (max 160o F) to rid the mats of oils. For best results use a mild soap or detergent with a pH between 4 and 9, to clean the mats. Do not use steam (unless specifically recommended), degreasers, or caustic chemicals. Do not machine wash or mechanically scrub the mats.
Q: Can you customize a mat to my specific requirements?
A: Yes we can. We offer 3 types of customization:
The level of customization by product is on the details tab at the bottom of every product page.
Q: Are the colors shown on your website the exact color I should expect to receive?
A: No, because monitors vary so there may be a slight variance in the color. If color choice is critical, we suggest that you order a sample. Due to manufacturing processes and material dye lots, color can vary, but our products fall within an industry-standard acceptable variation.
Q: Do 24/Seven LockSafe mats pose a tripping hazard?
A: 24/Seven LockSafe mats are available with 3" edging in yellow and black. The ramps allow for a smooth transition on and off the mat. The mats lock together with a patented interlock so they do not come apart, preventing the possiblity of a tripping hazard.
Q: Do your rubber mats smell?
A: Yes! Unfortunately, that rubbery smell is a feature of any rubber product. The mat should lose that smell over time. If you are planning to install rubber mats or flooring in any enclosed space, please remember that this can slow the dissipation of a strong rubber scent.
Q: What are the best floor mats for greasy warehouse floors?
A: Yes, the 5/8" thickness provides cushioning that reduces fatigue during long shifts. These industrial anti-fatigue mats work well in both standing workstations and areas with mixed traffic.
Q: Are these anti-fatigue mats good for standing all day in manufacturing?
A: Solid rubber floor tiles have a continuous surface that provides a smooth, stable standing area and is easier to clean. They are suited for dry spaces and heavy rolling equipment. Drainage rubber floor tiles have open grids that allow liquids to pass through, preventing pooling and maintaining traction in wet or spill-prone environments.
Q:What's the difference between solid and drainage rubber floor tiles?
A: Yes! Unfortunately, that rubbery smell is a feature of any rubber product. The mat should lose that smell over time. If you are planning to install rubber mats or flooring in any enclosed space, please remember that this can slow the dissipation of a strong rubber scent.
Q: Do your rubber mats smell?
A: Yes! Unfortunately, that rubbery smell is a feature of any rubber product. The mat should lose that smell over time. If you are planning to install rubber mats or flooring in any enclosed space, please remember that this can slow the dissipation of a strong rubber scent.
Q: Can I use interlocking rubber floor tiles in an automotive shop with chemicals?
A: Yes, these chemical resistant nitrile rubber floor mats handle brake fluid, coolant, hydraulic oil, diesel, and most automotive chemicals without degrading.
Q: Do interlocking floor tiles for warehouse use need professional installation?
A: No, these interlocking rubber floor tiles for industrial use require no tools or special skills. The tiles snap together by hand and can be reconfigured anytime.
Q: What makes nitrile rubber better than regular rubber for industrial floors?
A: Regular rubber breaks down when exposed to oils and solvents. Nitrile rubber maintains its structure and does not deteriorate in contact with petroleum-based products, making it essential for automotive, manufacturing, and industrial applications.
Q: Can I buy heavy duty interlocking floor mats with ramps online?
A: Yes, the 24/Seven LockSafe floor tiles are available for purchase online with optional ramp edging in yellow or black. The ramps create a smooth transition and reduce trip hazards.
