Packing with blanket or according to client’s request.
Quality Control
We strictly follow the standard of ISO9001-2008. Quality is in the
first place at every stage of production to ensure the product
compliance to the specification/standards. Careful inspections are
carried out by highly trained inspection engineers during every
procedure from raw material stage to finished product and delivery.
Jiangsu milky way steel poles co.,ltd
Estbilsed in 1989,Jiangsu Milky Way Steel Poles is located in Wuxi,East of China ,near one of the largest sea port of China ,Shanghai,Port .
Our Products have been widely used in the power transmsion ,signal transmission and ligting for street ,road ,square ,palaestra.and so on
We have plenty of export experience . Since our first overseas order from Pakstan in 1991 of 132 KV transmission poels ,our products have been deliveried to more than 70 contries and areas ,including America,Australia ,Russia ,Genmery ,Span,Philippines ,Malaysia and so on
To assure our products qualified ,we take steps as follows :
1. Management team : We have employ the foreign export to take chaege of the overall managemnt ,especailly the technical managemnt and quality management .
2. Introducing ISO management ,We are awared ISO 9001:2008 certificate . .
3. Lofting and design software :We have transmisson power pole design software which can help us design all kinds of steel pole ,at the same time ,the TMA and LMA are adopted by us to provide the design the drawing accuratly .
4. QC Inpection:It is our company policy that all the finish product should be inspected by our specialzed QC in every manufacure steps and beofore every shipment .
We are always persisting in horzontal cooperation with domestic senior project institute and technical colleges .The enterprise also has an highly qualified team working at R&D ,manufacure ,QC ,aftersales service and other important positions .
