Expanded metal is a type of metal stock made by shearing a metal plate in a press, so that the metal stretches, leaving diamond-shaped voids surrounded by interlinked bars of the metal. The most common method of manufacture is to simultaneously slit and stretch the material with one motion.
Expanded metal grating is normally heavy duty ,and commercial product made from regular (not flattened) nongalvanized steel. which for a variety of uses such as walkways, catwalks, screens, fencing, window guards, open trash containers, vent covers and many more applications. we have expanded metal in a variety of materials such as aluminum expanded metal, stainless expanded metal, galvanized expanded metal, carbon steel expanded metal, copper expanded metal, brass expanded metal and titanium expanded metal.
Instruction of installation :
Expanded metal grating on geotextile
- Size grating to meet expected loads, soil strength, and installation equipment. Use larger grating on very weak soils that have a low bearing strength (e.g., muck or peat). This spreads the weight over a larger area.
- Prepare the surface by smoothing out high spots and filling ruts. Do not disturb the root mat of any vegetation; it provides added support for the crossing. Cover the entire crossing area with nonwoven geotextile.
- Lay the grating in the wheel paths so that vehicles drive on the long part of the grating. Use quick links that are at least 3 inches by 3/8 inches or other heavy-duty links to join sections to the desired crossing length.
Expanded metal grating is lightweight, durable, inexpensive, and provides some traction. Operators don't need special equipment to install the grating.
Grating tends to bend to conform to any ruts that may develop. Equipment may be needed to remove grating if it becomes covered by soil.
Flip the grating occasionally to distribute wear. Remove and replace unusable bent sections.
