Galvanized Flatbar
Galvanized Flat Bar is a cost-effective alternative to stainless steel, offering long-lasting rust protection for up to 30 years. It is a practical solution for outdoor and exposed structural applications where corrosion resistance is essential.
Galvanized Steel Flat Bar is made from A36 hot rolled mild steel and coated with a zinc-rich layer through a hot-dip galvanizing process. This protective finish enhances its resistance to weathering, making it ideal for industrial and construction projects.
Hot-dipped galvanized (HDG) steel flat bar can be visually identified by its crystallized surface pattern, known as "spangle." This unique finish not only provides aesthetic appeal but also signals a strong zinc coating for enhanced durability.
Galvanized Flat Bar maintains the full strength of A36 structural steel while gaining added protection from its zinc coating. It is a reliable choice for bracing, supports, and framing in environments where long-term performance and resistance to corrosion are critical.

ASTM A123 standard for zinc (hot-dip galvanized) coatings on iron and steel products.
Applications
Used in shelving, brackets, sculptures, bracing, trim, and trailers.
Commonly used in structural support, general fabrication, and outdoor applications due to its high corrosion resistance.
Commonly used in structural support, general fabrication, and outdoor applications due to its high corrosion resistance.
Workability
Can be cut, machined, or welded using standard steel fabrication methods.
Adequate ventilation should be used to avoid inhalation of fumes when heated.
Saw-cut ends of pre-cut lengths are not galvanized and should be treated with a cold galvanizing compound.
