Stainless steel round pipe 88.9 mm (600 GRIT) — is a versatile high-quality structural rolled metal of a large diameter, which corresponds to the international standard DN 80 (3 inches) and is widely in demand in capital construction, industry, architecture, and design. The product has an exact outer diameter of 88.9 mm and is available in a wide range of wall thicknesses (from 1.5 mm to 4.0 mm), allowing the optimal selection of the product to meet specific requirements for structural rigidity, weight, and strength. The profile is manufactured using advanced automatic TIG (Tungsten Inert Gas) welding technology in an inert gas environment, which guarantees 100% monolithicity of the seam, full tightness, and visual invisibility of the welded joint. The seam is located strictly inside the product, and the entire outer surface of the bar undergoes premium multi-stage processing with ultra-fine abrasives to achieve the highest roughness class of 600 GRIT. It acquires a flawless mirror shine (chrome effect) that perfectly reflects light, simplifies maintenance, prevents the retention of dirt and dust, and gives metal structures a solid, modern, and premium look. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This large-caliber round profile is supplied in various grades of alloyed stainless steel (including the popular AISI 201, AISI 304 series, and premium acid-resistant AISI 316 steel), allowing flexible adaptation of the order to any budget and operational requirements (from dry interiors to aggressive industrial environments or outdoor conditions). The products strictly comply with the rigorous requirements of international engineering standards ASTM A-554 (USA) for structural pipes and EN 10296-2 (Europe). This guarantees flawless calibrated roundness, strict adherence to cross-sectional geometry, and wall thickness stability along the entire length of the bar. The country of origin of the products is Vietnam.
Scope of Application and Purpose
Due to its large diameter of 88.9 mm, the choice of wall thickness, and premium mirror polishing of 600 GRIT, this round profile is a rational engineering choice for many technical and architectural directions:
Construction, Fences, and Architectural Decor: creation of large-scale enclosing structures, complex spatial frames, elements of entrance groups, decorative racks, as well as exclusive details of modern interior and exterior in office, residential, and shopping and entertainment centers.
Mechanical Engineering, Machinery, and Transport: manufacture of durable frame elements, protective systems, power units, attachments, and parts of special transport, where a combination of high load-bearing capacity, vibration resistance, and aesthetic appearance is required.
Industrial Equipment and Commercial Objects: assembly of metal structures and frame supports for technological equipment, auxiliary lines at enterprises, in production workshops, and food blocks, as well as laying internal technical non-pressure pipelines, ventilation systems, and waste disposal lines without high pressure.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural stainless steel rolled products (standard ASTM A-554). Due to the specific nature of the structural TIG weld seam type, this pipe is categorically forbidden to be used as a high-pressure main pipeline in pressure engineering and utility networks. It is designed exclusively for non-pressure, gravity, ventilation, or open systems.
• Choice of Modification: corrosion resistance, allowable temperature range, and climatic limitations of the product directly depend on your chosen steel grade (AISI 201, 304, or 316) and wall thickness. Our technical specialists are always ready to help you choose the optimal modification for your project conditions.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the flawless chromed shine of the 600 GRIT coating, mild soapy solutions or specialized disinfectants without free chlorine should be used. Cleaning is performed using a soft cloth (microfiber) or a soft foam sponge, which effectively remove dust, light dirt, and fingerprints.
Prohibited Care Products:
It is categorically forbidden to use cleaning agents based on chlorine, active acids, as well as any abrasive powders, stiff metal brushes, or scourers. Abrasives leave micro-scratches on the gloss, which irreversibly destroys the mirror effect and reduces the protective properties of the outer metal layer.
The products are delivered in perfect commercial condition (new). Each bar is supplied in a protective polymer film, which completely guarantees the preservation of the mirror surface against scuffs, scratches, and accidental damage during transportation, loading and unloading operations, and installation.
