Stainless steel round pipe 50.8x2.0 mm AISI 304 (600 GRIT) — is a premium, reinforced element of structural metal products manufactured from high-alloy food-grade stainless steel. Due to the increased wall thickness of 2.0 mm, this profile is classified as thick-walled for its gauge, ensuring maximum bending stiffness, flawless resistance to deformation, and the capability to withstand extreme static and dynamic loads. The outer diameter is 50.8 mm, and the inner through diameter equals 46.8 mm. The profile is manufactured using the automatic TIG (Tungsten Inert Gas) welding method, which ensures complete tightness, monolithicity, and maximum strength of the weld joint along its entire length. The outer surface of the pipe undergoes thorough multi-stage mirror processing with ultra-fine abrasives to the highest roughness class of 600 GRIT. This creates a flawless chrome effect (gloss, mirror), which not only gives the product a premium appearance but also facilitates cleaning and completely prevents the development of bacteria or retention of dirt on the surface. The pipe is supplied in standard bars with a length of 6 m.
Material of Manufacture and Standards
This reinforced profile is manufactured from the universal and most widely demanded austenitic stainless steel grade in the world, AISI 304 (classic food-grade stainless steel, full analogue according to GOST — 08Х18Н10, European standard — EN 1.4301). The high content of chromium (18%) and nickel (10%) ensures the formation of a stable passive layer on the metal surface, which instantly self-restores upon mechanical damage and guarantees absolute resistance to oxidation and rust. Production is strictly regulated by leading international engineering standards ASTM A-554 (USA) for structural steel and EN 10296-2 (Europe), guaranteeing perfect geometric roundness and stable calibration along the entire length of the bar. The country of origin of this series is Vietnam.
Scope of Application and Purpose
The combination of a thick 2.0 mm wall, the outstanding corrosion resistance of AISI 304 steel, and the mirror shine of 600 GRIT makes this pipe an unalternative choice for objects with increased requirements for durability and strength. It is fully compatible with standard mounting hardware for railings. The profile is used for construction of the most heavily loaded stair railings, handrails in high-traffic areas, as well as specialized support holders and handrails for people with special needs.
Automotive Tuning, Body Armor, and Metal Structures: due to the high mechanical toughness of the steel, the pipe serves as the primary material for the manufacture of automotive grille guards (bull bars), protective bars, side steps, front bumper guards, exhaust system elements, and other structural body armor for SUVs and watercraft. Additionally, due to its structural stiffness, this profile is ideal for the production of outdoor flagpoles, flag holders, masts, external brackets, and decorative banner stands.
Recommended Environment: open air (outdoor application in all climatic conditions), areas with constant high humidity, aqua zones (swimming pools, saunas, bathrooms), food blocks (auxiliary and supporting structures), as well as medical institutions, laboratories, and clean production facilities where regular chemical disinfection is required.
Technical and Operational Limitations:
• Structural Purpose: the product belongs to the category of structural stainless steel products (ASTM A-554). Due to the specific geometry of the structural TIG weld seam, this pipe is forbidden to be used as a high-pressure main pipeline in industrial pressure systems and networks with extreme hydrodynamic loads.
• Chemical Mode: despite the outstanding corrosion resistance of the AISI 304 grade, its use in highly aggressive environments (concentrated mineral acids, industrial salt solutions, and constant contact with undiluted chlorine-containing compounds) should be avoided.
• Thermal Loads: the alloy features high thermal resistance and exceptional stability under temperature drops (thermal shocks). The maximum continuous working temperature is +600°C, and short-term thermal heating is allowed up to +850°C. The minimum operating temperature reaches extreme -196°C (suitable for cryogenic conditions).
Technical Recommendations for Mirror Surface Care
Recommended Cleaning Methods:
To preserve the flawless glossy shine of the 600 GRIT coating, it is recommended to use mild soapy solutions or specialized chlorine-free disinfectants. Cleaning is performed using a soft cloth (microfiber) or a soft sponge, which effectively remove dust, traces of precipitation, and fingerprints.
Prohibited Care Products:
It is strictly forbidden to use agents based on chlorine, active concentrated acids, as well as abrasive cleaning powders, stiff metal brushes, or scourers. The use of abrasives leaves micro-scratches on the mirror surface, leading to localized dulling of the gloss.
The products are delivered in perfect commercial condition (new). Each bar is supplied in a protective polymer film, which guarantees the preservation of the mirror surface against scuffs, scratches, and accidental damage during transportation, logistics, and installation works.
