Packaging:
We have a full range of expertise for Export Packing. We can pack
ASTM A312 TP 304 Stainless Steel Seamless Pipe so that they arrive
ready for use in perfect condition.304 Stainless Steel Pipe and
Tube Packing
304 Stainless Steel Seamless Pipes and Tubes is sleeved into
plastic bag individually,pieces wrapped with water-proof material,
bundled with nylon rope. Clear labels are tagged on the outside of
the package for easy identification of the quantity and product
I.D. Great care is taken during operation and transportation. If
required we arrange for packaging (also for sea freight), supply
plastic caps or protection rings at the pipe ends and organise
special marking.
