Cast Iron Grating
The metal casting market is ever changing. New cast iron grating suppliers are entering the market often. With a surplus of U.S. made products and castings from India, China and Brazil, it is difficult to keep up with the selection of available products and pricing unless it is your business. That is where Trenchdrain.biz can help.
Trenchdrain.biz is your source for replacement cast iron grating and conventional frame and grate trench drain systems for do-it-yourself projects. We supply systems and grates from some of the big names in cast iron trench drain grating, but we are also able to locate discontinued grating products and find castings from offshore sources. The selection is always changing so you will need to contact us to find out what products are the current price leaders.
Neenah Foundry
With over 125 years of casting experience, Neenah is a leading foundry for municipal and trench drain casting. They have a wide selection of rectangular and square grate sizes and styles. Their trench systems extend from light duty residential applications to extra heavy duty military and airport applications. Trenchdrain.biz supplies Neenah products as replacement grates or newly installed systems. Review the three grating families below and see whether one is right for your application.
Heavy Duty Trench Grating (R-4990 and R-4999 Series)
These trench drain grates range from sizes between 8 inches to 51 inches in width. The R-4990 series cannot be bolted down. The R-4999 products are identical to the R-4990 but have the added bolt hole feature. Grates are 1.5” to 2“ thick. Frames can be purchased if you are building a new trench system or you can buy grates individually.
Superior Durability Frame Series (R-4993 and R-4994)
The Superior Duty Frame series is for use at airports, ports, industrial sites and roads. The frames of these two systems have superior resistance to breaking while in use under extraordinary load conditions. The R-4993 has a type T frame, which features a 5” wide protective iron border along the grating. The R-4994 has a type S frame that features a unique frame shape with a wider, clear opening and a more integrated contact with the surrounding concrete.
Self Forming Trench Pan (R-4996)
Neenah also offers a cast iron self forming trench and grate system. This is actually a 30” or 36” long cast iron channel that is 10 inches deep, which becomes the trench lining. The trough is formed in concrete as would any polymer concrete system. Different outlet configurations are available for 4”, 6” and 8” pipe. Channels are available in 6”, 8” and 10” widths. This system is heavy duty.
