Standard tolerances for plank gratings
This sheet of tolerances applies to PcP. plank gratings with the following specifications:
- Height max. 70 mm
- Plank element width max. 333 mm and min. 50 mm
- Grating size 2,0 m², where one edge dimension does not exceed 2000 mm

 

Diagonal measure (cross measure)

The difference between D1 and D2 must not exceed:
± D1 - D2 0,012 x S where:

D1 : Diagonal measure 1
D2 : Diagonal measure 2
S : Largest side measure

 

Largest side measure	Max. 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

 

Radian measure, width & length

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

 

Side, cut-out & mesh measures

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