Length: 1-12m or customizable
Thickness: 0.8 – 4.0mm
Design Style: Customizable
Product Introduce
A500 Galvanized Square Steel is a cold-formed carbon structural steel that meets the American ASTM A500 standard and is formed into a square tube structure after hot-dip galvanizing. ASTM A500 (also known as A-500) Carbon Steel Pipe is a standard specification for cold-formed welded and seamless carbon steel structural pipes in round, square and rectangular shapes. ASTM A500 is the most commonly used hollow structural section (HSS) specification in North America.
The core features include:
High strength: The minimum yield strength is 46000 psi (310 MPa), and the tensile strength reaches 58000 psi (400 MPa).
Corrosion protection: The hot-dip galvanized layer (usually 50-100 microns thick) provides long-lasting protection and is suitable for outdoor and harsh environments.
Standardized production: Complies with ASTM A500 Grade C standard to ensure dimensional accuracy and mechanical properties.

Frequently Asked Questions (FAQ)
Q1: Can A500 galvanized square steel be used in marine environments?
A: Yes, it is. Our product has undergone third-party testing and its galvanized layer can resist corrosion for over 1000 hours in salt spray testing, making it suitable for offshore engineering.
Q2: How to ensure welding quality?
A: We use ER70S-6 welding wire and apply zinc rich coating to the heat affected zone after welding to maintain its anti-corrosion performance.
Q3: Does it comply with international certification standards?
A: In addition to ASTM A500, we can also meet standards such as GB/T 3094 (China) and EN 10219 (EU) to support export projects.
