Stainless steel round pipe 50.8x1.5 mm AISI 201 (600 GRIT) — is a high-strength element of structural metal products, which serves as a classic engineering standard for creating reliable fencing systems. Due to the increased wall thickness of 1.5 mm, this profile features enhanced bending stiffness, resistance to deformation, and the capability to withstand significant dynamic and anti-vandal loads. The outer diameter is 50.8 mm, and the inner through diameter equals 47.8 mm. The product is manufactured using the automatic TIG (Tungsten Inert Gas) arc welding method, which guarantees flawless density and monolithicity of the weld seam. The outer surface of the pipe is subjected to thorough multi-stage polishing with ultra-fine abrasives to achieve a reference roughness class of 600 GRIT. This provides the product with a flawless mirror gloss, chrome effect, and maximum smoothness. The profile is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This profile is manufactured from alloyed chromium-manganese-nickel austenitic stainless steel grade AISI 201 (a direct analogue according to GOST — 12Х15Г9НД, European standard — EN 1.4372). The modification of this alloy contains an optimal amount of nitrogen, which significantly increases the mechanical strength of the metal. AISI 201 acts as a highly effective and economically viable analogue of the more expensive AISI 304 grade for interior applications. Production is strictly regulated by leading international standards ASTM A-554 (USA) for structural steel and EN 10296-2 (Europe). This ensures precise calibration of geometric roundness parameters along the entire length of the bar. The country of origin of this series is Vietnam.
Scope of Application and Purpose
The 1.5 mm wall combined with a diameter of 50.8 mm makes this pipe a primary supporting and handrail element in the construction industry. It is perfectly compatible with most standard fasteners, flanges, and decorative connectors of stainless steel hardware. The profile is mass-used for the manufacture of main railing lines, staircases, atrium enclosures, as well as specialized support holders and handrails for people with special needs.
Protective Structures and Commercial Sites: due to its increased strength, the pipe is an ideal material for installing protective bumper guards in shopping and office centers, protecting glass displays from shopping cart impacts, designing reception desks, exhibition stands, and premium furniture elements. The mirror surface of 600 GRIT with a chrome effect provides the structures with a highly appealing appearance in high-traffic locations.
Recommended Environment: interior spaces of modern commercial and residential buildings, facilities with low or moderate humidity levels where there is no direct prolonged contact with water, atmospheric precipitation, or chemically aggressive substances.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products (ASTM A-554). Due to the specific geometry of the TIG weld seam, this pipe is strictly forbidden to be used as a main pipeline in high-pressure engineering networks for heating, hot or cold water supply under high internal pressure.
• Humidity and Chemical Mode: due to the reduced nickel content, the AISI 201 grade features average corrosion resistance. Operating the product in outdoor environments under continuous exposure to precipitation, in marine air, swimming pools, as well as in direct contact with chlorine-containing substances or active acids must be avoided.
• Thermal Loads: the profile stably withstands operation within a wide temperature range. The maximum continuous working temperature is +400°C, and short-term heating is allowed up to +550°C. The minimum operating temperature limit is -40°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original mirror gloss of the 600 GRIT coating, mild soapy solutions or specialized chlorine-free disinfectants should be used. Cleaning is performed with a soft cloth (microfiber) or a foam sponge, which easily remove dirt, dust, and handprints.
Prohibited Care Products:
It is strictly forbidden to use agents containing chlorine, active acids, as well as stiff metal brushes, scourers, or abrasive powders. Violation of these rules destroys the passive layer of the steel, leaves scratches, and leads to a rapid loss of gloss.
The products are delivered in perfect new condition, with each bar protected by a special polymer film, which completely eliminates the risk of scratches or scuffs during transportation, warehouse storage, and installation works.
