Our Phosphate Services 

Phosphate coating is a process used to provide rust-proofing for ferrous metals, and when applied with sealers, it offers superior corrosion protection.

Del's Plating Works offers both zinc and manganese phosphating services, with zinc phosphate being a lighter coating than manganese phosphate. The zinc phosphate coating is an excellent alternative coating for high-wear parts. Phosphate coatings are porous, which makes them ideal for surface preparation for additional coatings and painting.

We offer MIL-DTL-16232 phosphate coating Type Z and Type M, as well as TT-C-490 Type 1 phosphating services. Our process is capable of uniformly coating and plating parts with complex geometries, and we can achieve coating thicknesses up to 0.0002 inches thick.

Phosphating services are ideal for OEM firearm parts, fittings, fasteners, and as a prep treatment for paint or powder coating.



  • MIL-DTL-16232 Type Z and Type M
  • TT-C-490 Type 1



  • The finish provided by the phosphate coating will be gray to black in appearance.
