| Packages | Our poles as normal cover by Mat or straw bale at the top and bottom , anyway also can following by client required , each 40HC or OT can loading how many pcs will calculation base on the client actually specification and data. |
Material Test:
1. All of our material are purchased from famous mill factory to assure the quality
2. A mill certificate issued by the mill factory with stamp and signature must be provided before unload the
material in our factory; otherwise we have our reason to refuse the material.
3. Before put into production, all the material must pass the chemical and physical analysis to make sure that they
have met the requested strength and component.
Inspection:
Before shipment, we have a final inspector manager to check the products on every detail and component to
make sure it all meet the drawing.
Package and shipment:
Our poles as normal cover by Mat or straw bale at the top and bottom and wood between the poles to avoide the damage on the galvanization of the pole ,anyway also can following by client required , The loading capacity of 40HC or OT an be calulated calculation base on the client actually specification and data.
