20" wide galvanized iron slotted trench drain grate


Galvanized Iron Slotted Grate - 20" wide x 24" long x 1.5" thick - rated for DIN load class F.


This is one of our strongest 20" wide trench drain grates with a hot dip galvanized finish.  It is typically used on an 18" wide trench drain or 18" wide catch basin.  The larger openings plug less often making this grate ideal for the intake of large amounts of water.  Typical uses are trench drains in airports, sea ports, industrial and manufacturing facilities, and any other area where extremely high loads are present.
