Galvanized square tube

Galvanized square tube is a square cross-section steel tube that has been galvanized. It has the characteristics of anti-corrosion and extended service life. It is widely used in construction, machinery manufacturing, agriculture, transportation and other fields.
1. Main features
Anti-corrosion: The galvanized layer effectively prevents rust and is suitable for humid and corrosive environments.
High strength: The square cross-section gives it good bending and compression resistance.
Beautiful appearance: The surface is smooth and the galvanized layer provides a silver appearance.
Long service life: The galvanizing treatment significantly extends the service life.
2. Production process
Hot-dip galvanizing: The square tube is immersed in molten zinc liquid to form a uniform zinc layer with good anti-corrosion effect.
Electrogalvanizing: The zinc layer is formed on the surface by electrolysis, with a thin thickness, which is suitable for occasions with high appearance requirements.
3. Common specifications
Side length: 20mm×20mm to 200mm×200mm.
Wall thickness: 1.0mm to 6.0mm.
Length: Usually 6 meters, but can also be customized according to needs.
4. Application fields
Construction: used for steel structures, scaffolding, roof supports, etc.
Machinery manufacturing: used for mechanical frames, conveying equipment, etc.
Agriculture: used for greenhouses, irrigation systems, etc.
Transportation: used for guardrails, sign poles, etc.
5. Precautions
Storage: should be stored in a dry and ventilated place to avoid moisture.
Transportation: handle with care to prevent damage to the galvanized layer.
Cutting and welding: use appropriate tools to avoid affecting the anti-corrosion performance.
6. Market situation
Price: affected by steel prices, galvanizing process and market supply and demand.
Suppliers: many suppliers at home and abroad provide galvanized square tubes of different specifications and qualities.
Galvanized square tubes have become the preferred material in many industries due to their excellent performance and wide application.
