Galvanized Square Tube Product Introduction
Galvanized square tubes are square cross-section steel pipes made from high-quality carbon steel or low-alloy steel, formed through cold bending and then processed with hot-dip galvanizing. The zinc coating provides excellent corrosion resistance, making them widely used in construction, municipal engineering, machinery, and other industries.

Galvanized Square Tube Features & Advantages
1. Superior Corrosion Resistance
Hot-dip galvanized coating provides 20-30 years of protection, suitable for humid and acidic/alkaline environments.
2. High Strength & Lightweight
Square cross-section offers excellent bending resistance, 30%-50% lighter than solid steel.
3. Easy Installation
Can be directly welded, bolted, or assembled into frameworks, improving construction efficiency.
4. Aesthetic & Durable
Smooth, uniform zinc coating requires no additional painting, reducing maintenance costs.
5. Eco-Friendly & Cost-Effective
100% recyclable, long service life, and lower total cost compared to untreated steel pipes.
Galvanized Square Tube Applications
Construction: Steel structures, stair handrails, curtain wall supports
Municipal Engineering: Streetlight poles, guardrails, drainage systems
Machinery Manufacturing: Equipment frames, conveyor tracks, storage racks
Agricultural Facilities: Greenhouse frameworks, livestock fencing
Power & Telecom: Cable trays, signal tower supports
Frequently Asked Questions (FAQ)
Q1: What’s the difference between galvanized and regular square tubes?
A1: Galvanized tubes have a zinc coating, offering 5-8 times better corrosion resistance, ideal for outdoor or humid environments.
Q2: Will zinc coating peeling affect performance?
A2: Minor peeling can be repaired with zinc-rich paint; large-scale peeling requires replacement. We recommend ≥80g/m² zinc coating for critical applications.
Q3: Can they be cut or welded on-site?
A3: Yes, but cut edges must be painted with zinc-rich primer, and welding areas should be cleaned and rust-proofed.
Q4: How to identify high-quality galvanized tubes?
A4: ① Check for uniform, defect-free coating; ② Verify zinc thickness (≥60g/m²); ③ Request compliance certificates with national standards.
Q5: How often is maintenance needed for outdoor use?
A5: Inspect every 5 years in normal conditions; industrial/coastal areas require checks every 2-3 years for zinc layer integrity.
