To ensure a direct comparison was possible, both weighbridge types were deemed to be installed in an above ground installation and certified for trade use.
Generally speaking, a low profile steel deck weighbridge is ideal for light to medium duty weighing applications and is the weighbridge of choice for short term projects and/or where the potential for relocation is high.
Concrete deck weighbridges are more expensive to buy, require more costly civils work and also incur higher installation charges, but are much better suited to medium to heavy duty weighing applications. The immense strength of the reinforced concrete deck almost totally eliminates any potential structural damage caused by grossly overloaded vehicles that can cause significant damage to a steel deck weighbridge.
A concrete deck weighbridge has far less deck deflection under load while also providing greater spans between the load cells. To compensate for reduced structural integrity, low profile steel deck weighbridges usually require more load cells to allow the load to be more evenly distributed across multiple load bearing points.
|Very portable and easy to move from one spot to the other||Not Portable at all and difficult to move after deck has been poured|
|Low inertia, very low resistance to lateral forces which increase wear on moving parts||high inertia, very high resistance to lateral forces which reduces wear on moving parts|
|Steel deck tends to be slippery when wet or when covered with ice or snow||Concrete deck can have a broom finish applied which forms a very rough surface and is excellent for traction|
|Deck plate is subject to wear over long periods of time||Minimal to no wear on the concrete deck|
|Can typically be installed and weighing in 1 day||Once installed and deck is poured, the concrete can take up to 28 days to cure.|
|Repairable if structure is damaged||If concrete is damaged, it must be removed and deck has to be re-poured|
