Packaging & Shipping
We use sack to pack the poles or straw at the pole top and bottom, which is our normal package. We also use wood between the poles but cost just little higher than normal package. We normally use 40HQ container and our Port limit weight for 40HQ is 26Ton.
Inspection
To make sure the steel pole quality, we have professional technicians to inspect the poles before delivery. We have Lab Test, Workload Test, Steel thickness Test, Galvanization thickness Test, etc.
