Why calculate SDA container loading before shipment?
SDA hollow bars are heavy steel products normally supplied in bundled form. When preparing an international shipment, the available container payload can therefore affect the quantity that can be loaded.
A preliminary loading estimate helps buyers and suppliers understand the expected shipment weight, approximate bundle quantity and available payload before the final loading plan is prepared.
Loading Quantity
Estimate the approximate number of bundles that can be included in the shipment.
Shipment Weight
Estimate the total weight of the planned hollow bar shipment.
Payload Utilization
Understand how much of the available container payload may be used.
How the calculation works
The basic calculation starts with the estimated weight of one hollow bar bundle.
Theoretical loading quantity can then be estimated from the available container payload.
Hollow bars and matching SDA components
Depending on the available payload and packing arrangement, SDA accessories can also be considered as part of the same shipment.
