m & m grating
i will be reusing an existing m & m grating and i cannot find any load tables to determine its' capacity.  i also don't know its' yeild stress.  any information on m & m gratings would be greatly appreciated.  thanks
is m&m a manufacturer, such as mcnichols?
m&m grating is a type of grating.  i don't think it is used much now.  the company "fisher and ludlow" used to carry it but they don't anymore and they no longer have their load tables for it.
you might contact the manufacturer, as they do have a "contact us" button on the website.
regular bar-type grating loads are just based on simple beam theory.
