Other Information :
The tables of safe loads indicated have been computed using the following design parameters:
| UNIFORM LOAD |
CONCENTRATED LOAD |
 |
 |
| |
Uniform Load |
Concentrated Load |
| Step 1. Determine M: |
M= FSg |
M= FSg |
 |
Step 2. Determine U or C:
per metre width |
|
|
|
| Step 3. Check D*(m): |
|
|
|
| U |
= |
Uniform Load,
KN/m2 |
| C |
= |
Concentrated Load at Midspan,
KN |
| Sg |
= |
Section Modulus of Grating per metre width, m³ |
| Ig |
= |
Moment of Inertia of Grating per metre of width, m⁴ |
| D |
= |
Deflection, m |
| L |
= |
Simple Clear Span, m |
| E |
= |
Modulus of Elascity
(2.0684×10⁸ KN/m² for carbon steel) |
| F |
= |
Allowable Bending Stress
(165000 KN/m² for Carbon Steel) |
| M |
= |
Bending Moment, KNm |
|
* Deflection should not be in exam 1/200th of the clear span or 10mm whichever is the lesser, providing that the maximum permitted working stress for mild steel is not exceeded. For pedestrian comfort, deflection should not exceed 6.3mm under uniform load.
Light Duty Steel Grating is best suited for use in conjunction with pedestrian traffic, and for light, rubber pneumatic tire-rolling traffic (carts, dollies and hand trucks).
For other rolling loads (forklifts, cars, trucks, etc.) see the Heavy Duty Steel Grating section.
