What are forged flats?

Forged flats are open-die forged rectangular shapes with a lower thickness made with a variety of material options. The forged flats are used in a many applications such as heavy machinery, high pressure systems, or others.

How do I buy forged flats?

You can buy forged flats by requesting a quote with your unique requirements and application. We also offer unique services to form the flats with more exact needs.

Where are forged flats used?

Forged flats are used in industrial sectors such as oil and gas, press repair, aerospace, mining, and power generation. The flat thickness and varying sizes ensure these are best used for paneling, machinery, or other heavy duty applications.

Custom Forged Flats at Great Lakes Forge, Michigan

Forged flat bars are widely used across industrial sectors for structural frames, heavy equipment brackets, engine components, suspension systems, and other load-bearing structures. These rectangular, flat-shaped components are shaped from heated steel using open-die forging, a process that refines grain structure and delivers superior structural integrity and durability compared to standard plate or rolled bar stock. At Great Lakes Forge, we produce high-strength forged flat bars for demanding industrial applications. Whether your project calls for a standard configuration or a custom dimension, GL Forge can produce forged flats from any material in our inventory to match your exact specs.

Advantages of Open-Die Forged Flats

Open-die forging offers key performance and structural advantages. The forging process works the metal's grain structure in a way that casting and machining from bar stock simply cannot replicate. That translates to real performance benefits. Key advantages include:

Superior mechanical properties and grain structure
Available in custom dimensions not found in standard plate or bar stock
Increased toughness
Better impact resistance
Higher fatigue life under cyclic loading
Reduced material waste compared to machining from solid stock
