High Quality ASTM AISI GB A792 Cold Rolled Aluminum Zinc Coated Q235 Q345 Zinc Galvanized Steel Coil

Product Overview

Our ASTM A792 Cold-Rolled Aluminum-Zinc Coated Steel Coil (Galvalume) combines the strength of Q235/Q345 steel substrate with the superior corrosion resistance and longevity of a 55% aluminum-zinc alloy coating. This composite results in a lightweight, durable, and cost-effective material, ideal for various demanding industry applications.

Key Advantages

• Superior Corrosion Resistance
  The Al-Zn alloy offers up to 4× longer service life compared to traditional galvanized coatings, with enhanced oxidation protection and matte finish
  

• Enhanced Durability & Longevity
  The alloy structure ensures sacrificial protection and long-term performance, reducing maintenance and replacement costs
  

• Excellent Heat and Fire Resistance
  Aluminum present in the coating improves heat reflectivity and resilience against high-temperature exposure, making it suitable for heat-sensitive installations
  

• Aesthetic & Functional Finish
  The coating resists fingerprinting and surface damage, with an ideal base for painting or additional protective layers
  

• Wide Application Versatility
  Commonly used in construction, automotive, HVAC, appliances, and structural elements thanks to its strength-to-weight ratio and formability
  

• Eco-Friendly Choice
  Longer lifespan and recyclability contribute to sustainability and lifecycle efficiency.
