Galvanised Mild Steel Flat Bar

Galvanised mild steel flat bars are strong, corrosion-resistant metal bars used in a wide range of construction and fabrication applications. These flat bars are coated with a protective layer of zinc through a hot-dipped galvanisation process, which helps prevent rust and surface damage caused by exposure to the elements. This makes galvanised steel flat bars a practical choice for outdoor projects where long-term durability is essential.

At Buy Metal Online, we supply galvanised mild steel flat bars in a variety of sizes, with no minimum order so you can get exactly what you need for your project.

Key Qualities of Galvanised Mild Steel Flat Bar

Our galvanised mild steel flat bars combine strength and corrosion resistance, making them ideal for demanding environments.

The galvanising process gives the mild steel a distinctive crystallised pattern on the surface, known as a “spangle”. Learn more about galvanised steel.

Key Characteristics:

• • Corrosion Resistance: Good
• • Formability: Poor
• • Machinability: Good
• • Weldability: Poor 

Physical Properties:

• • Density: 7870 Kg/m³
• • Electrical Resistance: 1.59 µΩm
• • Melting Point: 1350 – 1530 °C
• • Modulus of Elasticity: 200 GPa
• • Thermal Conductivity: 45 – 64.8 W/m°K
• • Thermal Expansion: 12.06 µm/m-K

While the weldability rating is considered poor, galvanised steel flat bars can still be welded with the correct preparation and safety precautions. The zinc coating, while excellent for corrosion protection, can release toxic fumes and cause weld spatter during welding, so ventilation and protective equipment are essential.

Benefits of Galvanised Mild Steel Flat Bar

Galvanised mild steel flat bars are commonly used in commercial and industrial settings where durability and low maintenance are essential.

• • Corrosion Resistance: The zinc coating offers reliable resistance against rust, moisture, and corrosion.
• • Long Lifespan: Under typical conditions, galvanised flat bars last 20 to 30 years or more, although lifespan may be reduced in coastal or high-humidity environments.
• • Low Maintenance: Once installed, galvanised steel flat bars require minimal upkeep, reducing long-term maintenance costs.
• • Ready to Use: No further coating or treatment is needed before use, making it simple to work with.

Popular Uses for Galvanised Mild Steel Flat Bar

Thanks to their flat, rectangular shape, galvanised mild steel flat bars are a popular choice for both fabrication, construction projects, and structural reinforcement. The zinc coating ensures durability, providing long-lasting protection even in harsh environments.

The strength and corrosion resistance of galvanised steel flat bars make them ideal for a variety of structural and outdoor applications, such as:

• • Frameworks: Used in the construction of metal frames for structural support in buildings and metalworking projects.
• • Bracing: Used to add rigidity and reinforcement in building structures and equipment.
• • Outdoor Fixtures: Suitable for use in gates, fencing, and signage exposed to the elements.
• • Trailer Parts: Commonly used in the manufacture and repair of trailers.
• • Vehicle Construction: Ideal for components requiring durability in tough environments.
• • Panels: Used as support or edge trims for panel systems and cladding.
• • Decorative Metalwork: Ideal for fabricating custom brackets, edging, or other decorative pieces.
