Stainless steel round pipe 85x2 mm AISI 304 (600 GRIT) — is a high-quality premium rolled metal of a special large caliber, designed for capital construction, creation of urban space elements, industrial equipment, and commercial design. The product has an exact outer diameter of 85 mm and a wall thickness of 2 mm, providing an inner through diameter of 81 mm. Due to the combination of a thick two-millimeter wall and the unique properties of chromium-nickel steel, this profile possesses colossal structural rigidity, resistance to deformation, high anti-vandal and mechanical loads, and perfectly resists strong vibrations and atmospheric pressure. 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 or dust, and gives structures a solid, modern look. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This round profile is manufactured from high-quality alloyed austenitic stainless steel grade AISI 304 (known domestic analogue is 08Х18Н10, European standard is EN 1.4301). This grade contains a high concentration of chromium (18–20%) and nickel (8–10%), due to which it is known worldwide as "food-grade stainless steel". The material is absolutely eco-friendly, safe in direct contact with food products, biological environments, and water. AISI 304 has flawless resistance to intergranular corrosion, oxidation, and the effects of most chemical reagents, and also retains its plastic and strength properties under extreme temperature 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), which guarantees flawless calibrated roundness and wall thickness stability of 2 mm along the entire length of the product. The country of origin of the products is Vietnam.
Scope of Application and Purpose
Due to its large diameter of 85 mm, thick 2 mm wall, resistance to aggressive climate factors of AISI 304 steel, and premium mirror polishing of 600 GRIT, this pipe is an indispensable material for a wide range of complex tasks:
Urban Infrastructure and Parking Systems: manufacture of heavy-duty sidewalk and anti-parking bollards, reliable parking limiters, urban traffic separation systems, road fences, removable parking barriers, as well as anti-vandal bases for road signs, racks for information boards, supports for signposts, and navigation steles. The 2 mm wall provides high protection against accidental vehicle impacts.
Outdoor Structures, Masts, and Flags: design and installation of tall outdoor flagpoles, flag holders, external brackets, signal masts, and decorative interior racks for banners subjected to significant wind loads.
Industrial Equipment and Objects with High Humidity: assembly of elements of technological equipment, frames, protective covers, auxiliary structures in professional food blocks, pharmaceutical, and medical workshops. Due to the ideal smoothness of 600 GRIT, bacteria and dirt do not accumulate on the metal, which allows the pipe to be operated in bathrooms, swimming pools, outdoors in coastal marine zones, and for laying internal technical non-pressure pipelines.
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, or open systems.
• Operating Environment: despite its high resistance to atmospheric corrosion and fresh/salt water, the pipe is not recommended for use in highly aggressive chemical environments (concentrated acids, alkalis, specific industrial solutions) without coordination with the engineering project.
• Temperature Range: AISI 304 steel possesses outstanding thermal stability and high resistance to temperature drops. The cryogenic minimum operating temperature is -196°C, the maximum continuous operating temperature reaches +600°C (short-term peak heating without loss of strength and geometry is allowed up to +850°C).
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.
