    • What is the average lead-time when ordering a Pedimat?

      Lead times vary in all manufacturing operations but generally Construction Specialties Inc. is able to ship Pedimat within two and a half weeks from receipt of signed shop drawings. All submittal drawings will provide a proposed lead time. Please contact the factory if expedited service is needed.

    • How deep should the recessed opening for a Pedimat be?

      The depth of the recess will ultimately depend on the frame chosen for each application. The following detail pages are frame specific and show the frame depths.

      keywords: pedimat, deep, recessed, opening, depth, frame, application

    • Can I have the frames shipped ahead of the Pedimat?

      Yes, if the Pedimat is of a standard shape (square or rectangle). The frames for a odd-shaped Pedimat or one with cut outs will be built at the same time as the mat and fit tested for quality assurance before shipping.

      keywords: frames, ship, pedimat, standard, shape, square, rectangle, odd-shape, cut, fit, test, quality assurance

    • What is the maximum size mat available?

      Pedimat can be built to a maximum of 12' wide or a total of 100 square feet per module. The modules can be installed to an infinate size. Each of the following detail pages contains the weight per square foot for each product. Please keep these weights in mind when requesting very large modules because the mats will eventually need to be removed so that the recess can be cleaned. We do not recommend splices be located in the center of the doorway.

    • How are the Pedimat sections joined together?

      They aren’t. The shop drawings C/S provided will show the lay out of each section. The installer only has to lay the Pedimat in place as shown on the shop drawings.

    • Why is your weight capacity listed as a rolling load test?

      We have found the rolling load test to be the most comprehensive real-life test available. Most entrance mat failures are due to heavy loads being wheeled through an entranceway. The rolling load test utilizes a weighted 5" x 2" solid polyurethane wheel, which passes over the mat 1000 times. To pass the test the unit must withstand the proposed weight without any permanent deformation to the rails or inserts. Alternative testing methods which measure the amount of deflection or the amount of weight per square foot a unit can withstand simply do not offer the real-world severity an entranceway faces daily. For entryways in businesses such as retail outlets, airports, banks, or casinos, rolling load performance is a critical factor. We recommend units with the highest practical loading capability be specified for such entrances. To aid in the decision making process we recommend viewing the selection guide in our full catalog located in the Design Guide section of this manual. The selection guide lists the rolling load data for all C/S mats and grids.

    • How is the accuracy of a custom shaped Pedimat guaranteed?

      A high quality custom shaped Pedimat is dependent on the quality of the template. Construction Specialties Inc. offers a free template kit to assist in the process. We also offer an optional guaranteed template service. Contact the factory for a free template kit or to schedule the optional template service.

    • Do you manufacture custom Pedimats for inside revolving doors?

      Although Pedimats can be installed in this application, we do not recommend these products for use under revolving doors. The space requires that they be installed in many pieces and sharp edges result because of the small sections and radiused edges. Consider placement before or after the revolving door with a half-circle cutout to fit the space or consider Peditred G3 or G4, Design Step entrance carpet, or stainless steel Gridline® for placement inside revolving doors.

    • Is it possible to use a Pedimat on an ADA compliant ramp?

      Yes, using our poured abrasive or vinyl inserts you can meet the higher requirement for static coefficient of friction recommended by the ADA. The mat will also need to be mechanically fastened. Please contact the factory with this special request.

      keywords: pedimat, ada, compliant, ramp, possible, poured abrasive, vinyl, inserts, requirement, static, coefficient, friction

    • In what situations do you recommend a drain and pan?

      Since the Pedimat is a shallow depth product it is recommended that a trench drain be put in areas of higher than average snow or rainfall. We do not offer a pan for the Pedimat product line.

    • Do you manufacture custom Peditreds for inside revolving doors?

      Peditred G4 or Peditred G3 are both recommended for this space. Avoid a carpet insert however, opting instead for poured abrasive, recycled rubber or the G7 or G8 serrated models. Carpet can easily be pulled from the rails with the constant motion of a door sweep. Other options for under revolving doors include Design Step entrance carpet or stainless steel Gridline®. On any of these models, a template is recommended to ensure accurate fit.

    • Do you manufacture custom Pedigrids or stainless steel Gridline® for use inside of revolving doors?

      Although this product can be supplied in this application, we do not recommend Pedigrid for use under revolving doors. The 1 1/2” depth of the product can break the airlock, which negates the energy efficiency of the revolving door. Consider placement before or after the revolving door with a half-circle cutout to fit the space, or consider Peditred G3 or G4, DesignStep® Entrance Carpet, or stainless steel Gridline® for use inside revolving doors.

    • In what situations do you recommend a drain and pan?

      A drain is recommended in areas of higher than average snow or rainfall. We do offer a pan for all grids but including a pan adds costs and complexity to the manufacturing of the unit. We recommend a trench drain set in a level base frame whenever practical.

    • Why do the installation instructions call for such an oversized recessed block out for frame installation?

      There are many variables in deciding how to install frame. The field condition and finish floor type are the two most important factors. The standard instruction covers the typical installation where there is an oversized recess to set the frames and then is backfilled with grout. Typically there is a tile, carpet or terrazzo floor that will then be installed to about the installed Pedigrid frame. In the case where there will be exposed concrete adjacent to the installed frame, the choice would be to create a block out of the recess, Option #2 of the frame offerings would then be recommended followed with caulk or grout in the small gap left between the frame and the finished floor.

  • Gridline®
    • Do you manufacture stainless steel Gridline® for use inside of revolving doors?

      Gridline® is recommended for installation inside of revolving doors. The smooth flat surface and clean lines lends itself to a successful installation. A template is recommended to ensure accurate fit. Ask about our custom baffles to address air flow issues and energy efficiency.
