Surface Ground Steel Plate: Flatness You Can Measure, Precision You Can Trust

At AB Precision Grinding Co., we specialize in surface ground steel plates for demanding industrial applications. With decades of experience and a commitment to accuracy, our plates are ground to deliver exceptional surface finish, dimensional stability, and sub-thousandth tolerances.

We process steel grades including:

• A36 – Structural steel for general fabrication

• 1018 & 1045 – Carbon steels ideal for machining

• 4140 & 4142 – Alloy steels for strength and wear resistance

• D2, A2, and other tool steels for long-term durability

  
  

Our dedicated surface grinders deliver ultra-flat, mirror-like finishes perfect for:

• Machine tables and sub-assemblies

• Gauge blocks and reference plates

• Precision tooling and fixtures

  
  

Why choose surface grinding over Blanchard for steel?

• Tighter flatness across smaller tolerances

• Better surface finish for tight mating surfaces

• Ideal for parts that need to be within .0002” tolerance

  
  

With capabilities that rival some of the best grinding houses in the country, we serve customers nationwide who rely on precision from the first cut to the final inspection.
