Galvanized square tube

Galvanized square tube is a type of pipe obtained after galvanizing treatment based on square tubes. Here is a detailed introduction to galvanized square tubes:

Material and Shape

Typically made of low carbon steel or alloy steel, it has a square cross-section shape, and its side length can be customized according to different application needs, with common specifications such as 10mm×10mm, 15mm×15mm, 20mm×20mm, etc. The wall thickness generally varies between 0.5mm and 5mm.

Galvanizing Process

Hot-dip galvanizing: The square tube is immersed in molten zinc, allowing a layer of zinc to adhere to the surface of the square tube. The hot-dip zinc layer is relatively thick, generally over 20μm, providing good corrosion resistance and effectively preventing steel from rusting, making it suitable for use in harsh outdoor and humid environments.

Electro-galvanizing: Using the principle of electrolysis, a layer of zinc is deposited on the surface of the square tube. The electro-galvanized layer is relatively thin, usually between a few microns to tens of microns, with a bright and uniform appearance, but its corrosion resistance is slightly inferior to that of hot-dip galvanized square tubes, generally used in indoor decoration, electronic equipment, and other places with higher aesthetic requirements and relatively better environments.

Features

Excellent corrosion resistance: The zinc layer can form a dense zinc oxide film in the air, which effectively prevents oxygen and moisture from contacting the surface of the steel, thus preventing rust and corrosion, greatly extending the service life of the square tube.

Good decorative properties: The surface of the galvanized square tube is smooth and has a uniform color, providing a certain decorative effect, making it suitable for use in construction decoration, furniture manufacturing, and other fields that require aesthetic appeal.

Strong strength and stability: The structural shape of the square tube itself gives it high strength and good stability, performing excellently under pressure and weight, meeting the needs of various engineering structures.

Good processing performance: Galvanized square tubes are easy to cut, weld, bend, and other processing operations, allowing for customized processing according to specific engineering requirements, facilitating the quick and convenient production of components in various shapes and sizes.

Application Fields

Construction Industry: Commonly used for building scaffolding, protective railings, curtain wall frameworks, roof drainage systems, etc. Its corrosion resistance ensures long-term use in outdoor environments, while the shape and strength of the square tube meet the load-bearing requirements of construction structures.

Mechanical Manufacturing: In the field of mechanical manufacturing, galvanized square tubes can be used to manufacture supports, frames, and conveying pipelines for various equipment. For example, in the conveying equipment of automated production lines, galvanized square tubes can serve as the supporting structure for the conveying track, ensuring the normal operation of the equipment with their strength and stability.

Automotive Manufacturing: Some automotive components are produced using galvanized square tubes, such as the seat frame and dashboard supports. The galvanized layer can enhance the corrosion resistance of these components, extending the lifespan of the vehicle.

Furniture Industry: Can be used to make frames for tables and chairs, borders for wardrobes, bed frames, etc. Its aesthetic appearance and good strength make it one of the ideal materials for furniture manufacturing.

Market Advantages and Development Trends

Market Advantages

High cost-performance ratio: Compared to other metal pipes with similar performance, galvanized square tubes are relatively inexpensive, and due to their long service life and low maintenance costs, they have a high cost-performance ratio, making them highly competitive in the market.

Environmental protection and energy saving: During the production process, the energy consumption of galvanized square tubes is relatively low, and they can be recycled, meeting modern society's requirements for environmental protection and energy saving, thus receiving increasing attention and favor in the market.

Development Trends

High performance: With continuous technological advancements, the performance of galvanized square tubes will continue to improve, such as developing higher strength, more corrosion-resistant, and high-temperature resistant galvanized square tubes to meet the demands for high-performance materials in aerospace and high-end equipment manufacturing.

Green and environmentally friendly: In the context of increasingly strict environmental protection policies, the production of galvanized square tubes will pay more attention to green and environmental protection, adopting more environmentally friendly galvanizing processes and production equipment to reduce pollutant emissions and minimize environmental impact.

Multi-functionality: In the future, galvanized square tubes will not be limited to traditional application fields but will also develop towards multi-functionality. For example, developing galvanized square tubes with self-cleaning, antibacterial, and fire-resistant functions to meet the diverse functional needs of different fields.
