Height 1200mm G550 Q235B Steel Structure Construction 6


At currently we have three types loading plan as below:


1 We use 4O"HQ container, This way we loading and unloading is very slow and diffcult. But this way is the lowest cost.


2 We use 40" OT container, we can load all members easily. and good way to protect the possible damage during shipping. But that will cost more ocea freight.


3 We still use 40" HQ, but we could make a steel pallet to put all members on it. And then we push it into the container, this way is the fastest way to loading and unloading, and we can make the pakage to project any damage during shipping. But the steel pallet will cost about 1800 usd per pc.
