Stainless steel square tubing is a hollow, long strip of steel widely used in building structures, industrial machinery, and decoration due to its high corrosion resistance, high strength, and aesthetic appeal. Common materials are 304 and 316L, with dimensions typically ranging from 10 x 10 mm to 300 x 300 mm and wall thicknesses varying from 0.4 mm to 12 mm. It features strong bending and torsional resistance and reduces structural weight.
The following is a summary of the detailed specifications and applications of stainless steel square tubing:
1. Main Specifications of Stainless Steel Square Tubing
Common side length ranges: Small sizes such as (10×10, 15×15, 20×20, 25×25, 30×30); Medium sizes such as (40×40, 50×50, 60×60, 75×75); Large sizes such as (100×100, 150×150, 200×200) and even reaching (300×300 mm). Wall thickness range: Standard thickness is 0.8 mm - 8.0 mm; light-duty thickness can be as thin as 0.4 mm, and heavy-duty thickness can be greater than 10 mm.
Material classification:
304: Corrosion resistant, good machinability, suitable for general environments.
316/316L: Contains molybdenum, resistant to marine and chemical corrosion, suitable for harsher environments.
201: High cost-performance ratio, relatively weak rust resistance, suitable for dry indoor environments.
Length: Standard length is usually 6 meters, but can be customized upon request.
2. Main uses of stainless steel square tubes:
Architectural decoration: Used for high-grade stainless steel security windows, stair railings, guardrails (bridges, roads, balconies), landscape fences, curtain wall frames, and interior and exterior decoration.
Mechanical structures: Used for frames of various automated mechanical equipment, structural components of packaging machinery, food machinery, and pharmaceutical machinery due to their high strength and corrosion resistance. Industrial fluid pipelines: Used for transporting fluids requiring high cleanliness, such as those found in food, beverages, and pharmaceuticals. Municipal engineering: Used for courtyard fences, street sign supports, and rust-proof engineering frames. 3. Selection Guidelines
Indoor and general environments: 304 stainless steel is preferred for its aesthetics and practicality.
Seaside and chemical environments: 316/316L stainless steel must be selected to prevent corrosion.
Load-bearing structures: Choose square tubing with a larger wall thickness (e.g., 3 mm or more). Stainless steel square tubing, with its various specifications, meets different needs from light decorative applications to high-strength structures.
