Description
As a leading stainless steel pipe & tube supplier in China, CIVMATS produce and manufacture a wide range of stainless steel rectangle pipes & tubes. The supply of our SS rectangle pipes & tubes comes with multiple sizes and various grades which are both customizable. Choose CIVMATS and find the best stainless steel rectangle pipes & tubes. Stainless steel rectangle pipe is hollow stainless steel long product and can be classified into seamless and welded by process. Seamless stainless steel rectangle pipe can be further divided into hot rolled SS pipe, cold rolled SS pipe, cold drawn SS pipe and extruding SS pipe, while cold rolled and cold drawn pipes are processed on hot rolled pipes. Welded stainless steel rectangle pipe mainly falls into two categories: straight-seam SS welded pipe and spiral SS welded pipe. CIVMATS produce both seamless and welded stainless steel rectangle pipe, available in multiple size and various grades as per ASTM, JIS, EN, DIN and GOST standards. The main grades of stainless steel rectangle pipe we produce are 304(L), 316(L), 321. Customization, whether in terms of grade or dimension, is acceptable so long as the quantity meets our MOQ requirement (1 Ton per size). Our stainless steel rectangle pipe is extensively used for conveying fluid medium, like oil and gas, water, steam etc. Due to its relatively lighter weight under the same bending strength and torsional strength, stainless steel rectangle tubes are also widely used in the production of machine parts and engineering structure.

Package
Plastic Bag
Wooden case
In CIVMATS, all of our stainless steel rectangle pipes & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes & tubes together in batches. However, for some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation. For enhanced customer experience, we also provide dedicated package as per your special requirements.
Logistics
By Sea
By Air
By default, we will quote based on sea transportation, such as FOB, CFR, CIF and the like for most enquiries or orders. Quotation based on air transportation is also optional upon your request for urgent demands.
