Grating comparison hub
Three decisions decide 80% of a grating specification: construction (welded vs press-locked), material (galvanized vs stainless vs aluminum), and chemistry (steel vs FRP). The pages below put them side-by-side with load data, costs, and selection rules.
Welded vs press-locked bar grating
Two dominant construction methods. Welded is the industrial default; press-locked is the architectural choice. See the 12-row comparison table plus load-capacity factors.

Galvanized vs stainless vs aluminum grating
Material decision driven by corrosion environment, load, and budget. Compare density, strength, corrosion life, and cost per square meter.

Steel vs FRP grating
When chemistry beats steel. FRP in caustic, acidic, or electrically sensitive environments vs the economics and strength of galvanized steel.
