Trusted Stainless Steel Square Bar Suppliers

The exceptional mechanical properties of our stainless steel square bars include:

• Tensile Strength: It is a minimum 515 MPa and is well suited for applications requiring high loads.
• Yield Strength: Usually over 625 MPa, used in structures and industries.
• Elongation: Up to 50%, so there is always a possibility to adjust without losing the stability of the structure.

Such characteristics make our square bars suitable for use where strength, ductility and resistance to deformation under load are desirable.

The assurance of following globally recognized standards and certifications emphasizes our commitment to providing high-quality, reliable, and safe products.

Standards Compliance:

• ASTM A789: Specifies requirements for seamless and welded stainless steel tubes for general corrosion and low-temperature service.
• ASTM A790: Covers seamless and welded ferritic/austenitic (duplex) stainless steel pipes for corrosive environments.
• EN 10088: European standard for stainless steel grades, chemical compositions, and mechanical properties, ensuring high-quality materials. 

Industry Certifications:

• ISO 9001: Quality management system guarantees consistent and reliable products.
• PED (Pressure Equipment Directive): Meets safety and design requirements for pressure related applications.
• ASME (American Society of Mechanical Engineers): Under engine approval procedures, products are validated for compatibility with international engineering standards and boiler codes.

These standards and certifications guarantee reliability, quality assurance, and compliance with strict global standards to build the trust and satisfaction of our customers.

Our test and quality ensure every product meets the highest performance, durability, and safety standards.

• Positive Material Identification (PMI): Chemical composition verifies compliance with the grade.
• Hydrostatic Testing: Strengthening and leak-free operation in pressure-based applications.
• Radiographic Testing: It detects internal defects for reliability in marine and structural applications.

Our quality assurance practices are committed to excellence, and our products are always of the highest quality and consistently above customer expectations and industry benchmarks.

Application & Advantages

Due to their ability to withstand extreme environments, square bars are made to be used in all areas of the industry, providing exceptional performance.

• Power Generation: Where high temperatures and pressure are expected, square bars are used in Power plant and Energy sector.
• Chemical Industry: High resistance to acid and alkaline environments makes them fit for use as reactors, storage tanks, and processing equipment.
• Marine Industry: Our square bars are corrosion resistant to salty environments and are thus used in shipbuilding and offshore structures.
• Aerospace: They are light yet strong and used in aircraft components that require precision and high-stress performance.
• Medical Industry: These bars are used in medical devices, implants, and surgical tools because of their biocompatibility and strength.

Extreme strength, durability, and resistance to harsh conditions make our square bars suitable for any sector.

Manufacturing Process

The square bars are made in several stages, starting from moulding and rolling, and reshaping to a desired form. The key processes include:

• Hot Rolling: The grain structure of the steel is changed by heating to a temperature above the recrystallisation temperature to give improved strength and flexibility.
• Cold Rolling: The steel is rolled below recrystallisation temperature at room temperature having a smooth refined surface.
• Cold Drawn: This process is also conducted at room temperature and stretches the steel into wire like forms, increasing precision.

Our steel is subjected to one of these processes based on customer specifications to become square bars with varied mechanical properties in different applications.

Logistics and Product Documents

We prioritise efficient logistics and comprehensive product documentation to ensure smooth, on time deliveries globally.

• Material Test Certificate (MTC): Guarantees the chemical and mechanical integrity of the product so that it complies with the requirements of the industry and the customers.
• Customs Declaration: Crucial for international trade, which is a listing of the classification, value, and place of the item for smooth custom processing.
• Packing List: Offers comprehensive information about what is in the shipment, facilitating the inspection process and maintaining data integrity.
• Invoice: A document describing the value of goods, the conditions of sale and the payment scheme.
• Bill of Lading (B/L): Acts as evidence of the agreement between the carrier and shipper and includes terms of the shipment.

With comprehensive logistics support and transparent product documentation, we ensure efficient delivery, compliance, and customer confidence in every transaction.

We have a wide range of materials that allows us to provide solutions for each industry that are high quality and durable, and designed to meet each industry’s specific demands.
