This type of grating is used in areas where heavy static or rolling loads are encountered including heavy vehicular truck traffic up to H-20 loading. Calculations for vehicular loadings are based on AASHTO Standard Specifications for Highway Bridges and can be calculated by our Engineering department for your specific applications.
Heavy Duty Welded carbon steel is the most popular choice where high strength is required. For those applications requiring an ADA type product, our Wheels n' Heels® product offers the strength of the standard welded grating along with a spacing which allows 1/4" opening between bearing bars which conforms to the provisions with the "Americans with Disabilities Act" for pedestrian and wheelchair accessibility. To round out our heavy duty line, Ohio Gratings offers our heavy duty riveted product which is the oldest grating product on the market and continues to be popular with the engineering community.
