What is galvanized square tube? The base of the galvanized square tube directly forms a corrosion-resistant structural tight layer with the molten weld metal. Due to the existence of this structural tight layer, the molten weld metal can be effectively prevented from intergranular corrosion (near the welding heat affected zone). Therefore, it has good atmospheric corrosion resistance and good high-temperature oxidation resistance; at the same time, due to the protective effect of the galvanized layer, the surface of the component has a very smooth, dense and strong protective film, which greatly improves the adhesion of the coating; in addition, it also has moisture-proof and anti-corrosion properties.
Advantages of galvanized square tubes:
- Light weight
- High strength
- Long service life
- Easy installation
- Beautiful appearance
- Environmental protection and energy saving
- Simple and fast construction
- Resource saving
- Safety and fire prevention
- Wide range of specifications
Uses of galvanized square tubes
Construction field. Galvanized square tubes are used for the support and framework of building structures, such as beams, roof trusses, doors and windows, stairs, ceilings, walls, etc. It is also used in the manufacture of curtain wall engineering and mechanical equipment.
Bridge and road fields. Galvanized square tubes are used to construct guardrails and side railings to ensure the safety of pedestrians and vehicles. It is also used in the construction of bridges and roads.
Weak current engineering and communication facilities. Galvanized square tubes are used for wiring pipes and telecommunication line brackets. They have good conductivity and are durable.
Industrial field. Galvanized square tubes are used to transmit gases, liquids and other substances, such as oil pipelines, compressed air pipelines, etc. It is also used in the petroleum industry, chemical coking equipment, etc.
Agricultural field. Galvanized square tubes are used for pipes in water conservancy projects, such as agricultural irrigation water systems. It is also used in steel frame greenhouses, fruit and vegetable sheds, etc.
In addition, galvanized square tubes are also used for decorative purposes such as home decoration, door and window frames, etc., with good decorative effects and corrosion resistance.
