Car Wash Grate Flooring by National Grating

As a car wash owner or contractor, you know that you are in the business of looking good. Choose the flooring option that gives a clean, professional appearance – FRP Car Wash flooring grate and trench grates from National Grating. Available in several distinctive colors, the fiberglass reinforced grating we offer will keep its color, resist stains and clean easily. The right choice for new installs, or to replace unsightly corroded and rusty steel grating.

Easy Sizing and Installation

Car wash floor grating from National Grating is much easier to transport, fabricate and install than heavy steel grating. First of all, it weighs a fraction of the steel, while giving comparable performance. No need for welders and torch-cutters – you can easily cut FRP grating yourself with your circular saw and a diamond blade. (See our super-easy cutting guide.)

Easy Clean-up

FRP grating weighs much less than steel gratings. Are you dreading the task of levering out heavy steel grates that pinch fingers and toes and strain your back? Fiberglass grating is so much easier to handle! Cleaning out drain trenches is no longer the hazardous and muscle-busting chore it once was.

Avoiding Theft and Vandalism

An unfortunate reality is that metal thieves prey on unprotected areas in your facility. Metal grating in open areas is easily stolen and sold for scrap value, causing inconvenience and an unsafe environment for your customers. FRP has no scrap metal value for thieves. Bad guys begone!

Lower Cost of Ownership

With a long service life and the ability to handle the product yourself (no welders or steel fabrication required), FRP car wash grating will save you all those extra contractor repair costs over the years.

The Thickness and Sheet Sizes You Need

FRP grating comes in several types, molded (usually a pattern of squares), pultruded (a series of bars), or mini-mesh (smaller holes). We are happy to suggest the right solution for your need. Questions you will need to consider include:

  • chemical-resistant-car-wash-frp-gratingwill the grating have foot traffic only or automotive traffic as well?
  • is extra performance required (i.e., handling heavy-duty vehicles)
  • what span is required?
  • what lengths are required?
  • if going into an existing installation, what is the depth of the drain trench?
  • have you ensured that there are adequate shoulders to support the grating?
  • what color would you like? (Ask our reps for colors available for your specs.)
  • would you like a gritted non-slip surface for extra safety?
  • which grating sheet sizes will give you most efficient cuts? We can help you with this!

Durable and Attractive

FRP grating from National Grating will perform for years without fading or cracking, and you will never have to worry about rust!
