Defense Plating Services in Texas

For a processor it means two things: carrying the flow-downs that arrive with the order, and not introducing non-compliant material into your part. We do not supply the base metal, so the specialty-metals restriction at DFARS 252.225-7009 follows your material certificates; what we control is the process chemistry, the records, and the handling of controlled information. What we hold is listed on our certifications and approvals page.

Drawings, models and specifications that arrive with a controlled job are treated as controlled data: restricted internal access, no forwarding outside the company, and no offshore review. We are ITAR registered and will confirm handling in writing before you transmit anything. Mark an export-controlled print as such on the RFQ rather than waiting for the purchase order.

Yes — chemical agent resistant topcoat over a qualified epoxy primer, which in turn needs the correct pretreatment: conversion coating on aluminum, zinc phosphate or a plated undercoat on steel. That work runs through our Rowlett campus, where plating and CARC and MIL-spec painting are on the same site. Give us the full stack callout from the drawing, not only the topcoat number.

Yes. In MIL-DTL-5541 the type describes the chromium chemistry while the class sets the balance between corrosion protection and electrical contact resistance, so a Type II Class 3 callout and a Type I Class 1A callout are different products from the same line. The combinations, and what each is used for, are laid out on the MIL-DTL-5541 chem film specification page. Yellow chem film runs at Rowlett.

Cadmium plating runs only at our McAllen plant, to AMS-QQ-P-416 with the chromate type and post-plate bake your drawing calls for. It remains available for defense work; the pressure on it comes from European chemical regulation and from primes retiring it on new designs, not from a domestic ban. If a program is planning a conversion, put it on a new part number rather than a drawing change mid-build.

Usually, but the sequence matters more than the finishes. Steel and aluminum in one weldment cannot go through the same tanks, so either the details are finished before assembly or areas are masked and treated separately. Threaded and sliding interfaces on that hardware often want a dry film lubricant, which runs at Rowlett, rather than a second coat of paint. Send the assembly print with the finish marked per detail.
