Standard tolerances for plank gratings

This sheet of tolerances applies to plank modules with the following specifications:

  • Height max. 70 mm
  • Plank element width max. 333 mm and min. 50 mm
  • Grating size max. 2.0 m2, where one side measure does not exceed 2000 mm.

The difference between D1 and D2 must not exceed:

Where: ± D1 - D2 ≤ 0,012 x S
D1 : Diagonal measure 1
D2 : Diagonal measure 2
S : Largest side measure

 

Largest side measureMax. D1-D2
200 2,4 mm
400 4,8 mm
600 7,2 mm
800 9,6 mm
1000 12,0 mm
1500 18,0 mm
2000 24,0 mm

 

For L/B > 450 mm: 1/150 x L/B, yet max. 8,0 mm
For L/B ≤ 450 mm: max. 3,0 mm

For L/B > 600 mm: 1/200 x L/B, yet max. 8,0 mm
For L/B ≤ 600 mm: max. 3,0 mm

L & B : +0 / -4 mm
d : ± 1,5 mm
d10 : ± 4,0 mm (over 4 plank elements)
f, e, g, ⌀ : +8 / -0 mm

Smaller/other tolerances may be applied on request.
