Stainless steel round pipe 42.4x1.2 mm AISI 201 (600 GRIT) — a high-quality lightweight structural metal product of precise round gauge, optimized for creating elegant interior structures, furniture frameworks, and decorative fencing systems. Having a popular outer diameter of 42.4 mm, this profile provides the most comfortable and anatomically correct grip for a palm, while a wall thickness of 1.2 mm classifies it into the category of thin-walled products. This engineering ratio allows to significantly reduce the overall weight of the metal structure without losing rigidity on long spans, while the inner through diameter is exactly 40 mm. The model is fully compatible with standard fittings and connecting elements of 42 mm gauge. The profile is manufactured using advanced high-precision automatic TIG welding technology. The weld joint is located inside the product (the inner surface remains untreated), and the outside is subjected to multi-stage mirror polishing with ultra-fine abrasives to the highest roughness class of 600 GRIT (chrome, mirror, gloss). This makes the outer weld absolutely imperceptible visually and tactually, guaranteeing flawless architectural aesthetics, a premium shine, and significant budget savings compared to analogs made of more expensive steel grades. The pipe is supplied in bars with a length of 6 m.
Material of Manufacture and Standards
This thin-walled profile is manufactured from durable alloyed stainless steel grade AISI 201, which is a direct reference analog of the alloy 12X15G9ND according to GOST and the European standard EN 1.4372. Due to the optimized chemical composition with the addition of manganese and nitrogen, this metal has increased surface hardness, high tensile strength, and provides sufficient corrosion protection in many moderate operational environments. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) and EN 10296-2 (Europe), which guarantees perfect geometric roundness of the product, stable dimensional precision along the entire length of the bar, and maximum reliability of the weld joint at the molecular level. The country of origin for this series of metal products is Vietnam, whose plants are known for strict quality control and a reference level of factory surface polishing.
Scope of Application and Purpose
The combination of a lightweight 1.2 mm wall, a demanded 42.4 mm circumference, and flawless mirror gloss (600 GRIT) makes this pipe the best choice for objects requiring an attractive appearance and a long service life at an affordable price. It is mass-used for the installation of light railing systems, fences, stairs, wall-mounted handrails, as well as specialized holders for people with special needs inside buildings. The model is a basic standard for the interiors of modern office and shopping malls with controlled humidity, exhibition pavilions and stands, the manufacture of designer furniture, light decorative structures, as well as in automotive engineering and mechanical engineering.
Recommended Environment: interiors of modern office, residential, and large shopping complexes, exhibition pavilions, premises with low or controlled humidity, moderate (non-aggressive) industrial and urban environments, objects of technology and mechanical engineering.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural metal products (ASTM A-554) and is designed to create light frame and decorative structures. Due to the wall thickness of 1.2 mm and the specifics of its purpose, this pipe is strictly forbidden to be used as a main pipeline in systems under high hydrodynamic, steam, or any internal pressure.
• Environmental Specification: the AISI 201 steel grade has limited corrosion resistance in aggressive zones. It is not intended for operation in environments with constantly high humidity, in open outdoor areas under long-term influence of precipitation, as well as in direct contact with chemical alkalis, mineral acids, or chlorine-based compounds.
• Temperature Regime: the profile is designed for moderate thermal loads (resistance to temperature drops is medium). The safe maximum continuous operating temperature is +400°C. Maximum short-term thermal heating is allowed up to +550°C. The minimum operating temperature of exploitation is -40°C.
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the original reference glossy shine of the 600 GRIT surface, mild soapy solutions or specialized chlorine-free disinfectants should be used. Cleaning is performed exclusively with a soft cloth (microfiber) or a foam sponge, which easily remove dust and traces of touch.
Prohibited Care Products:
It is not allowed to use agents containing chlorine, active acids, as well as abrasive powders and stiff metal brushes or scourers. Failure to comply with these rules leads to micro-damage of the passive protective layer of the product, the appearance of scratches, and rapid dulling of the gloss.
The products are delivered in proper commercial condition (new) in a protective polymer film, which completely minimizes the risk of accidental damage, scratches, and scuffs during logistical operations, warehouse storage, and installation.
