Classification and Typical Applications of Square Tubes

Ⅰ. Classification by materia

ⅰ. Metal square tubes
Aluminum alloy square tube
Features: Light in weight but high in strength, the surface can be treated with anodic oxidation, powder coating, fluorocarbon paint, etc., and has excellent anticorrosion performance.
Application: Interior: Shopping mall ceilings, office building corridors, airport terminals.
Outdoor: Sunshade blinds for building facades, balcony railings, and garden landscape pergolas.
Stainless steel square tube
Features: Extremely strong corrosion resistance. The surface can be processed with mirror finish, brushed finish, titanium plating, etc., with high gloss.
Application: Highend hotel decoration, kitchen equipment frames, outdoor sculpture structures.
ⅱ. Wooden square tubes
Solid wood square tubes
Features: It has a natural wood grain texture. Commonly used woods include pine, fir, walnut, etc. Anticorrosion and moistureproof treatments are required (such as applying wood wax oil).
Application: Japanesestyle ceiling, tea room partition, kindergarten decoration, such as the "natural style" ceiling made of pine square tubes and hemp ropes.
WPC square tube
Features: Made of wood powder and plastic, it is waterproof and insectproof. The surface can imitate wood grain embossing, and it is environmentally friendly and formaldehydefree.
Application: Outdoor pergolas, office partitions,balcony ceilings, kitchen and bathroom partitions, such as anticorrosion grape trellises built with woodplastic square tubes.
ⅲ. Plastic/composite material square tubes
PVC square tube
Features: Low price, light weight, resistant to water and chemical corrosion, but poor heat resistance.
Applications: Bathroom ceilings, temporary exhibition racks, greenhouse frames.
GRG square tube
Features: Made of glass fiber reinforced gypsum, customizable in arc and irregular shapes, with a fine surface, suitable for highend artistic designs.
Application: Theater ceilings, hotel lobby irregularshaped decorations, such as the flowing space created by wavy GRG square tubes.

Ⅱ. Classification by functional scenarios

ⅰ. Ceiling square tube
Function: Dividing space, concealing pipelines, and enhancing depth. It is combined with lighting to create a layered effect.
Case: Aluminum square tube ceiling in the office combined with LED light strips enhances the sense of transparency in the space.
ⅱ. Partition square tube
Function: It divides areas while maintaining the openness of the space. It often uses highdensity arrangements, such as the wooden square tube partition between the dining room and the living room.
ⅲ. Decorative square tube
Function: Pure aesthetic design, such as the vertical arrangement of aluminum square tubes on the exterior walls to form a "vertical line" building skin, or the artistic installation of colorful square tubes spliced inside.
