Expanded Metal Grating

Temporary crossings can be made from expanded metal gratings. Expanded
metal grating is a commercial product made from regular (not flattened)
nongalvanized steel. The grating is placed on top of nonwoven geotextile.

Where Used

Operators can use expanded metal grating crossings on shallow wetland or sandy soils. They also can be used on roads that don’t have high spots (e.g., stumps or large rocks) where grades are less than 4 percent. Because skidding causes the grating to move, this option is best limited to hauling and forwarding.

Application

Expanded metal grating crossings are usually built in sections that are about 4 feet by 10 feet. Operators install crossings by hand-placing the grating sections in each wheel path.
