Flat Expanded Metal

About Flattened Metal

Flattened expanded metal is manufactured by passing the standard expanded sheet through a cold roll reducing mill. Flattened expanded metal turns the strands and bonds down to provide a flattened surface, reducing the thickness (gauge) and elongating the pattern. Thickness may vary plus or minus 10% from published dimensions.

About Metal Grating

Grating is a standard expanded metal pattern produced from heavier gauge low carbon steel plates. Strands and the openings of grating are considerably larger than other meshes. It is ideal for use wherever a strong, durable, lightweight surface is needed. Although used primarily for pedestrian traffic, grating can accommodate heavier loads if properly supported.
  • DESIGN SIZE - Actual dimensions SWD and LWD. Measured from a point to a corresponding point.
  • SWD - Nominal dimension Short Way of Design
  • SWO - Short Way of Opening
  • LWD - Nominal dimension Long Way of Design
  • LWO - Long Way of Opening
  • STRANDS - The sides of the expanded metal design
  • STRAND - THICKNESS Gauge thickness of metal expanded
  • STRAND WIDTH - Amount of metal fed under dies to produce one strand
  • BOND - The solid intersection of two strands.
