Stainless Steel
Stainless steel sheets, plates, pipes, tubes and coils in grades 304, 304L, 316 and 316L for chemical, food and marine applications.
Stainless Steel Pipe, Sheets and Plates Supplier for the Middle East
Stainless steel is the material of choice for applications requiring corrosion resistance, hygiene and long service life. Tianjin Sino East Steel Group supplies stainless steel pipes, sheets, plates and tubes in grades 201L, 304, 304L, 316 and 316L to the GCC market, serving the food industry, chemical plants, desalination facilities, hospitals and architectural projects across the UAE, Saudi Arabia, Qatar and Kuwait.
What Stainless Steel Products Do We Supply?
Stainless steel is an iron-chromium alloy with a minimum chromium content of 10.5%, which forms a self-healing oxide layer that prevents corrosion. The most common austenitic grades - 304/304L and 316/316L - combine excellent corrosion resistance with good formability and weldability. Grade 316 adds molybdenum, which provides superior resistance to chlorides and makes it the preferred grade for coastal and marine environments, chemical processing and desalination plants.
We supply stainless steel in the following product forms: seamless and welded pipes, round tubes, sheets, plates, coils and profiles. All products are available in a variety of surface finishes including 2B, BA, No.4 brushed, mirror (8K) and hairline, depending on the application.

Frequently Asked Questions
What is the difference between 304 and 316 stainless steel?
Grade 316 contains molybdenum, which significantly improves corrosion resistance to chlorides and acids. For coastal GCC environments, chemical plants and desalination applications, 316/316L is strongly recommended; for interior architectural and general industrial use, 304 is usually sufficient and more economical.
Can you supply stainless steel with mirror finish?
Yes. We supply 8K mirror finish stainless steel sheets and tubes for architectural applications, as well as No.4 brushed and hairline finishes.
Do you provide Mill Test Certificates for stainless steel?
Yes. Every shipment includes an EN 10204 3.1 Mill Test Certificate with the chemical composition confirming the grade, plus mechanical properties where required.
Can you supply stainless steel pipes for food and beverage applications?
Yes. We supply hygienic stainless steel pipe in 304L and 316L with smooth internal surfaces suitable for food and beverage processing lines.
What is the minimum order quantity for stainless steel?
For standard grades and sizes we can supply from 5 metric tons. Smaller quantities can be arranged for approved stockists and project orders.
