    The best welding accessory product on the market
    standing on the cold concrete floor in all temperatures takes it out of your body, but now i have the weldsafe mat from Wearwell, i am more productive and happier when i get home after my full day. (Posted on 12/30/14) (Posted on 4/21/2015)

    Q: What are the benefits of using anti-fatigue floor mats?

    A: Anti-fatigue mats are designed to offer a wide range of benefits to employees and employers. Anti-Fatigue floor mats can increase worker productivity, reduce slips, trips and falls and improve the overall health of your employees.

    Q: How do anti-fatigue mats improve overall health of my employees?

    A: Standing long-term, especially on hard, unforgiving concrete leads to lower back pain, swelling of joints and poor circulation that can lead to varicose veins. Standing on anti-fatigue matting allows for continuous muscle movement which leads to increased blood flow to the legs, feet and back. Continuous blood circulation reduces fatigue, alleviates back pain and reduces swelling.

    Q: How do anti-fatigue mats increase employee productivity?

    A: Fatigue eventually leads to lack of focus and concentration on the task at hand. Anti-fatigue mats reduce worker fatigue allowing them to remain focused on the job at hand.

    Q: Can WeldSafe mats be exposed to liquids?

    A: WeldSafe mats were designed to be placed in dry work centers or work centers with minimal overspray. The sponge on the underside of your mat can absorb fluids it comes in contact with causing the mat to wear out prematurely.

    Q: How do I clean my WeldSafe mat?

    A: Sweep regularly or dry-mop the surface. These mats can be wet-mopped with mild soap or detergent. For best results, use a detergent with a pH between 4 and 9.

    Q: Can I cut or modify my mat?

    A: We do not recommend that you cut or modify your mat in any way. In fact, cutting the mat yourself will void the warranty. We offer our WeldSafe matting in 1ft cut lengths so you can order any length of matting that you need. We also customize matting if you require a unique shape or configuration.

    Q: Can you customize a mat to my specific requirements?

    A: Yes we can. We offer 3 types of customization:

  • C1- Custom lengths
  • C2- Custom lengths and widths
  • C3- Fully custom (size & shape)

  • The level of customization by product is on the details tab at the bottom of every product page.

    Q: There 2 sides to my mat. Which side do I stand on?

    A: The top side of the mat is the side with the pebbled texture pattern. The Sponge side of the mat touches the floor.

    Q: I just took my mat out of the box and laid it on the floor and the edges aren't lying flat.

    A: Please allow the mat to acclimate to the environment for 24-48 hours. Once it has acclimated the edges will lay flat.

    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: Does this mat pose a tripping hazard?

    A: Our WeldSafe mats are machined beveled (sloped edge) on all four sides. This allows for a smooth transition on and off the mat and do not pose a tripping hazard.
