In industrial platforms and mechanical equipment systems, steel ladders, climbing steps, maintenance passages, and operating platforms are the core structures to ensure the safe passage of personnel.
1. Staircase steel grating selection requirements
Minimum width of step board: ≥600mm
Load-bearing capacity: should be able to bear 1.5kN concentrated load (single point test)
It is recommended to use toothed steel grating + anti-skid front edge, models such as G325/30/100, G405/30/100
2. Vertical ladder steel grating step requirements
Consistent spacing (250mm±10)
Must have foot stability and anti-skid performance
It is recommended to use anti-skid punched steel steps or toothed steel grating
3. Aisle/channel steel grating standards
Minimum channel width: ≥500mm (single person), ≥800mm (double person)
Must set double-side guardrails + skirting boards, and the aisle steel grating must meet 5kN/m² uniformly distributed load
Common models: G323/30/100, G405/30/100, G325/40/100
In addition to the requirements for the size, strength, and anti-slip properties of steel gratings, DIN EN ISO 14122 also emphasizes:
The strength of the matching fixings must meet the pull-out load
The surface treatment must be corrosion-resistant (hot-dip galvanizing is recommended)
The installation error must not exceed the standard
