Square tubes are hollow structural sections with a square cross-section, commonly used in construction, manufacturing, and various engineering applications. Their uniform shape and strength make them a popular choice for a wide range of uses. Here are some key features and applications:

1. Product Features:
Shape and Dimensions: Square tubes have equal sides, providing a consistent and stable structural profile. They come in various sizes and wall thicknesses to meet different design requirements.
Material Composition: Typically made from carbon steel, stainless steel, or aluminum, square tubes offer excellent strength, durability, and resistance to corrosion (especially when made from stainless steel).
Surface Finish: Available in various finishes, including galvanized, painted, or untreated, allowing for customization based on aesthetic preferences and functional needs.
2. Application Fields:
Construction: Widely used in building frameworks, supports, and columns, providing structural integrity and load-bearing capabilities.
Manufacturing: Utilized in the production of machinery, equipment, and assembly line structures, offering versatility in design.
Furniture: Commonly used in furniture design for creating tables, shelves, and other functional pieces due to their aesthetic appeal and strength.
Signage and Displays: Employed in the fabrication of sign frames, display racks, and kiosks, offering a durable and stable foundation.
3. Specifications and Standards:
Square tubes are available in a range of specifications, conforming to international standards such as ASTM, EN, and JIS, ensuring compatibility across various applications and industries.
4. Production Process:
The production of square tubes typically involves processes such as hot rolling or cold rolling, followed by cutting and finishing to achieve precise dimensions and surface quality.
