Packaging

Please don’t worry that our products are packed, stored, transported according to the international regulation. We do care about the quality of our products; even some little details are paid attention to. We wrap the stainless steel products with anti-rust paper and steel rings to prevent damage. Identification labels are tagged according to standard specification or customer's instructions. Special packing is available as per customer's requirement. Plus, our storage racks are made of wood. Other kinds of metals are settled in other places, far from the stainless steel. Any unwanted chemical reaction can be prevented.

Raw materials are sending to hot rolling units for rolling into different sizes.

→Hot rolled material is annealing in cold rolled annealing furnace and pickling in acid.

→All mill rolls are grinded on precision grinding machine with proper chamfering after first shift operation.

→All sheets are pickled in different tanks and dried on brush roll machine before dispatched.

→These sheets are again annealing and are sent to straighten machine for straightening.

→Inspections are done at various stages. Keep proper control overall internal process via rolling, annealing and pickling by our experienced staff.

Packing Information of Stainless Steel Sheet/Coil/ Pipe:

Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might otherwise be caused during storage or transportation.
