Stainless steel round pipe 70x1.5 mm AISI 304 (600 GRIT) — is a high-quality, durable, and aesthetically flawless element of structural metal products with a hollow round cross-section. The product has a precise outer diameter of 70 mm and a reduced wall thickness of 1.5 mm, providing an inner through diameter of 67 mm. This geometric configuration allows for excellent structural bending stiffness with minimal specific weight, significantly reducing the load on supporting nodes and simplifying installation work. The profile is manufactured using automatic TIG (Tungsten Inert Gas) welding technology in an inert gas environment, which guarantees 100% monolithicity and absolute density of the welded joint with a weld seam efficiency factor equal to one. The seam is located inside the product, and the 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 does not fade over time, prevents the retention of dirt and bacteria, and is as simple to maintain as possible. 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 austenitic food-grade stainless steel grade AISI 304 (well-known domestic analogue is 08X18H10, European standard is EN 1.4301). Due to its high content of chromium (18%) and nickel (10%), this alloy is completely non-magnetic, possesses exceptional resistance to oxidation, high ductility, impact toughness, and is perfectly weldable by various methods. AISI 304 stainless steel excellently resists long-term exposure to moisture, atmospheric phenomena, and moderately aggressive environments, making it indispensable for long-lasting structures. Production of the rolled products is strictly regulated by leading international engineering standards ASTM A-554 (USA) for structural pipes and EN 10296-2 (Europe), which guarantees perfect geometric roundness and wall thickness stability along the entire length of the bar. The country of origin of this series is Vietnam.
Scope of Application and Purpose
Due to its premium mirror polishing of 600 GRIT, fundamental corrosion resistance, and rational cost, this stainless steel pipe is a priority choice for a wide range of outdoor and indoor construction, infrastructure, and decorative projects.
Outdoor Advertising and Architectural Metal Structures: the outer diameter of 70 mm is ideal for manufacturing reliable and high wind-resistant flagpoles, flag holders, masts, outdoor brackets, decorative banner stands, as well as long-lasting elements of fences, railings, and handrails outdoors.
Auto Tuning and Heavy Structural Body Kits: the mirror profile is in high demand for the production of protective body kit elements for SUVs, minivans, crossovers, and pickup trucks (bull bars, side steps, protective bars, and front bumper guards), ensuring exceptional aesthetics and vehicle protection against corrosion during the winter period.
Urban Environment, Security, and High-Humidity Zones: manufacturing of durable anti-vandal outdoor road bumpers, sidewalk and anti-parking bollards, parking restrictors, removable parking barriers, and urban traffic separation systems. Due to its moisture resistance, the pipe is ideal for use in coastal areas, swimming pools, saunas, bathrooms, and restrooms.
Recommended Environment: outdoor operation in moderate climate conditions, coastal and wet zones, office and shopping centers, furniture manufacturing, exhibition halls, indoor production workshops, mechanical engineering, the transport sector, as well as auxiliary and technological structures in food blocks (due to the high sanitary and hygienic properties of the material).
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural stainless steel products (standard ASTM A-554). Due to the specific nature of the structural TIG weld seam type and the lightweight 1.5 mm wall, this pipe is categorically forbidden to be used as a high-pressure main pipeline in pressure engineering networks.
• Chemical and Corrosion Mode: despite the high resistance of the AISI 304 grade, it is not recommended for use in highly aggressive environments (concentrated industrial acids, high-concentration alkalis, or specific saline solutions).
• Thermal Loads: the profile demonstrates exceptional stability under critical thermal loads and high resistance to sharp temperature drops. The maximum continuous operating temperature is +600°C, maximum short-term heating (peak) is allowed up to +850°C, and the minimum operating temperature reaches extreme -196°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original chromed shine of the 600 GRIT coating, mild soapy solutions or specialized disinfectants without free chlorine should be used. Cleaning is performed exclusively with a soft cloth (microfiber) or a soft foam sponge, which effectively remove dust, dirt, and fingerprints.
Prohibited Care Products:
It is categorically forbidden to use cleaning agents based on chlorine, active mineral 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 can trigger pitting corrosion of the metal's outer 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 logistics, loading and unloading operations, and installation.
