Descripción del Producto
Galvanized Square Tubes and Rectangular Tubes are welded hollow steel sections protected by a durable zinc coating that helps prevent rust and environmental corrosion. Designed for both structural and decorative applications, these tubes combine strength, versatility, and long service life.
Manufactured from high-quality carbon steel, galvanized hollow sections are widely used in steel construction, fencing systems, machinery fabrication, solar support structures, and municipal engineering projects. Their excellent durability makes them a preferred choice for projects requiring reliable performance in challenging environments.
Many steel structures fail prematurely due to corrosion.
When ordinary steel tubing is exposed to rain, humidity, industrial emissions, or coastal conditions, rust begins to form on the surface. Over time, this can result in:
- Loss of structural integrity
- Increased maintenance expenses
- Frequent repairs and replacements
- Reduced project lifespan
- Poor visual appearance
For contractors and project owners, corrosion protection is often one of the most important factors when selecting structural steel materials.
Galvanized square and rectangular steel tubes provide a practical solution by covering the steel surface with a zinc coating.
- Strong resistance to rust and oxidation
- Longer lifespan than untreated steel
- Lower maintenance requirements
- Excellent performance in outdoor environments
- Suitable for industrial and commercial projects
- High strength-to-weight ratio
The galvanized layer protects the steel even if minor surface scratches occur, helping maintain long-term performance.

The zinc coating protects the steel tube through a dual-protection mechanism.
The galvanized surface isolates the steel from moisture, oxygen, and contaminants.
Because zinc is more chemically active than steel, it corrodes first when exposed to harsh conditions. This process protects the underlying steel and significantly delays rust formation.
As a result, galvanized steel tubes remain durable and reliable for many years in outdoor applications.
Recommended:
- 25*25 mm to 80*80 mm
- Thickness 1.0–3.0 mm
Recommended:
- 100*100 mm to 250*250 mm
- Thickness 3.0–8.0 mm
Recommended:
- 300*300 mm and above
- Thickness 8.0–16 mm
Consider:
- Structural load requirements
- Installation environment
- Zinc coating thickness
- Project lifespan
- Budget and maintenance costs
Its zinc coating provides superior corrosion resistance, helping extend the service life of the steel structure.
Hot-dip galvanizing generally offers a thicker coating and better long-term protection for outdoor applications.
Yes. They can be painted after proper surface preparation if additional aesthetics or protection is required.
Absolutely. Their corrosion resistance and structural strength make them ideal for photovoltaic support structures.
Yes. Custom sizes, wall thicknesses, lengths, and zinc coating requirements can be produced according to customer specifications.
