We firstly possess a perfectly developed transport by which we can deliver goods directly from the warehouse to the customer. Secondly, we direct traffic, which ensures a delivery from the factory to customers from 15 tons. SS T304L Rectangular Tubing that are not in stock at our own warehouse are based on the star traffic from other sites - every day! We aim at providing professional customer service with one-stop purchasing, along with superior quality control, competitive price, fast lead time and convenient transportation.
While marking we choose a specific item number as well different color shade to differentiate steel grades. We mark SS T304L Rectangular Tubing as needed with the most suitable & visible marking technique.
We deliver from stock and warehousing as well as directly from the mill.
Packaging is an integral part of the product. It guarantees that the SS T304L Rectangular Tubing is delivered to the customer in the required quality. For smaller orders the size of the SS T304L Rectangular Tubing bundle depends on the no. of Tubes ordered, for larger orders the tubes are packed into individual bundles and in such a way that the maximum weight of 4000kg per bundle is not excedded. Bundle tied down with steel tape. Bundle tied down by steel strap underlaid by tapaten.
We can also provide SS T304L Rectangular Tubing wooden box packing, cardboard boxes, plastic wrapping, using hardened paper with PE meshing (used as protection against mechanical damages of tubes), into tapaten and polyethylene sheet etc.

Background 304L Stainless Steel
Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm). Grade 304H with its higher carbon content finds application at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.

304L Stainless Steel Pipes and Tubes Corrosion Resistance
Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 600C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 600C.
304L Stainless Steel Pipes and Tubes Heat Treatment
Solution Treatment (Annealing) - Heat to 1010-11200C and cool rapidly. These grades cannot be hardened by thermal treatment.
