Tolerances for pressure-locked gratings 

Back

 

Standard tolerances for mesh gratings
This sheet of tolerances applies to pressure-locked gratings with the following specifications:
- Bearing bars 60 x 5 mm
- Mesh size max. 66 mm and min. 11 mm
- Grating size max. 2.0 m2, where one side measure 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 measur	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: max. 3,0 mm 

 

For L/B > 600 mm: 1/200 x L/B, dog 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 10 meshes)
f, e, g, Ø : +8 / -0 mm

 

 

Smaller/other tolerances may be applied on request.
