EnviroGrid® adjustable series is designed to provide more flexibility in section size. Section and cell size will change as each section is expanded to the required dimension. Section length can be increased or decreased by adding or subtracting cells at no additional charge.
EGA Series Nomenclature:
EGAXAYPT - NC
(XA) Nominal Panel Length in feet (20, 30 & 40)
(Y) Cell Depth in Inches (3, 4, 6, 8, 10 & 12)
(P) Perforated (T) Textured
(NC) number of cells long
Example: EGA404PT-29
EGA 40 ft panel length, 4-inch cell depth, perforated and textured, 29-cell section length. Standard sections are manufactured from 58 strips of HDPE, resulting in a section length of 29 cells and 5 cells wide. Each strip is the appropriate width and 142 inches (3.6 m) in length. Weld spacing is 28.0 in ± .12 in (711 ± 3 mm). Cell density is 9 cells per meter squared. Cell walls are textured and if perforations are required 16% ± 3% of the cell wall is removed.
