Freight Shipping Information

How soon do you need it delivered. Extending the shipping time can lower the cost.
Will the delivery need to be scheduled?
If you do not have either a dock or a forklift at your delivery location, and your shipment is over 100 lbs, then a special delivery truck with a hydraulic lift will be used to get your shipment to the ground.
If the delivery driver has to bring the shipment inside an office building or more than a few feet past the rear of the trailer, inside delivery will apply.
