Common Specifications of Steel Grating

Usually, the center spacing of flat steel is distinguished by series
Series 1 - 30mm
Series 2 - 40mm
Series 3 - 60mm
Center spacing of cross bars distinguished by type:
Type A - 100mm
Type B - 50mm
1. Flat steel: Material is Q235 or stainless steel, with common flat anti-slip serrated and cross-section | types. Common specifications include 20x5, 25x5, 25x3, 32x3, 32x5, 40x5, 40x3, 50x5, 65x5, 75x6, 100x8, 100x10, etc. 2. Cross bars: Material is Q235 or 304 stainless steel round steel, twisted square steel, square steel, or hexagonal steel. Twisted square steel is made by twisting round wire drawn into square wire, with common specifications of 5x5, 6x6, 8x8mm, etc.Common Steel Grating Safety Load Span and Deflection Relationship Table
Series 1 (Flat steel center spacing 30mm)
Note: To the left of the load line is the corresponding span under a uniformly distributed load of 4Kpa with deflection ≤5mm, which is the maximum deflection for comfortable pedestrian walking.
Series 2 (Flat steel center spacing 40mm)

Note: To the left of the load line is the corresponding span under a uniformly distributed load of 4Kpa with deflection ≤5mm, which is the maximum deflection for comfortable pedestrian walking.
Series 3 (Flat steel center spacing 60mm)

Note: To the left of the load line is the corresponding span under a uniformly distributed load of 4Kpa with deflection ≤5mm, which is the maximum deflection for comfortable pedestrian walking.
