Tolerances

General details:
The tolerance limits apply to the the gratings, planks and frames manufactured by ElefantRiste A/S.

Tolerances, exterior dimensions:

Length/Width	Tolerance
Gratings of length/width ≤ 1000 mm	+0 / -3 mm
Gratings of length/width > 1000 ≤ 2200 mm	+0 / -4 mm
Frames and frame parts	+3 / -1 mm

Height	Tolerance
Gratings	+1,5 / -0,5 mm
Frames	+1 / -1 mm
Stair treads, plank gratings and planks	+3 / -1 mm

Diagonal dimensions

(diagonal measurement)

Diagonal dimensions (diagonal measurement) for gratings, planks and frames:
D1 = Diagonal dimension 1
D2 = Diagonal dimension 2
L/B = Largest side dimension

Max. deviation on diagonal dimensions
Largest side dimension	Max. D1-D2
200 mm	2,0 mm
400 mm	3,0 mm
600 mm	4,0 mm
800 mm	5,0 mm
1000 mm	6,0 mm
1500 mm	8,0 mm
2000 mm	12,0 mm

Tolerances, bars and edge bar:
Inclination, bars/edge bar:
p max. = 0,1 x H2, but max. 3 mm

Difference in height for bars:
q max. = 1 mm

Difference in height for bars and edge bar:
s max. = ± 1 mm

Distance from bars to edge bar:
t max. = 1,5 mm

Tolerances of cutouts in gratings and planks:
The tolerance limits apply to the gratings and planks manufactured by ElefantRiste A/S.

Radian height	1/150 x L/B but max. ± 8 mm
p for L/B 450 < L/B £ 2000 mm:	max. ± 3,0 mm
