Bhawal Steel Agency is a steel manufacturing industry, where we produce different types of steel products. We are the manufacturer, dealers, suppliers and stockist of steel products. We supply our products and services globally by taking all types of safety measures and precautions. Our stainless steel square pipes are designed considering international and national standards.

Stainless steel square pipes are made of high quality raw material. There are various types of grades in this austenitic steel series, which are generally applicable in massive industries for a variety of applications. Stainless steel pipes are used for transferring acids, gases and other liquid chemicals from one place to another.

Stainless steel square pipes are made of high alloyed elements like chromium, nickel, titanium, etc. These pipes are enriched with great weldability and forming properties. Stainless steel square pipes support welding, annealing, and pitting. They have excellent stability and strength.

There are various grades in stainless steel square pipes. Square pipes can stand firm against heat, rising temperature and high pressure. These pipes consist of great mechanical and chemical properties. Stainless steel square pipes can bear high heat and bad weather conditions. These austenitic pipes have high carbon content with excellent thermal conductivity.

Stainless steel square pipes are generally being used on construction sites, they are used for assisting bridges, buildings and plants, these pipes are also used for the manufacturing of bicycles, furniture, doors, windows, etc.

Stainless steel square pipes have high tensile and yield strength with high elongation. These pipes are produced by using high quality raw material and a strong combination of heavy alloyed elements such as nickel, chromium, molybdenum, etc.

Bhawal Steel Agency provide stainless steel 304 pipe, Jindal 304 stainless steel pipe, stainless steel square hollow pipes at the best price.
