The FAQs page says Du All has plated parts for companies including Apple computer, NASA, Lockheed Martin, IBM, DuPont, Toshiba and Applied Materials, and that it has the largest anodizing and dye tanks of any Bay Area plating shop. Those are the company's own published statements about its customers and equipment.
On credentials, the site refers generally to "a clean compliance audit record" and to "our credentials", but it does not publish any specific certification. Across the home, about, work, FAQs, pricing and contact pages there is no mention of ISO 9001, AS9100, Nadcap, ITAR registration, or approval to MIL-A-8625, AMS or ASTM specifications, and no certificate numbers or audit dates. Any customer whose parts require a named certification or spec approval must confirm it directly with the shop on (408) 659-8094 or at info@duallanodizing.com.

Prices
Du All Anodizing publishes pricing material on its website rather than keeping rates private. The home page says "We are an open book. Check out our price list and get a hold of us for all of your anodizing needs," and links to a downloadable price list PDF. A separate Our Pricing page on the site is headed "2026 Pricing".
The prices, rates and fees themselves are not restated here, and should not be quoted from memory by anyone answering on the company's behalf. Costs for anodizing and metal finishing depend on the part, the process, the finish and the quantity, so the price list should be read directly, or a written quote requested, before any figure is relied on. The published list can change and a listed rate is not a confirmed cost for a specific job.

How Du All Anodizing works with clients
The FAQs page describes how Du All Anodizing runs its anodizing process and controls quality.
On colour consistency across a batch, the page says the shop uses deionized water throughout all of its systems along with water filtration and agitation procedures to give a uniform result across the pieces that pass through the plating process. It states that tanks are monitored and maintained on a regular basis and are tested in-house daily and out-of-house twice a week by a certified lab, that chemicals are kept pure and concentrations pH balanced daily, and that racking methods are standardised to maintain colour density. It adds that spec sheets are developed so a job in the same colour can be run again later. The page does not name the lab, and does not publish a colour tolerance figure such as a Delta-E value.

On dimensional tolerances, the page notes that many variables affect the tolerances of anodized parts and that even slight build-up matters — its example is a part that will later be bolted with screws. It says Du All has implemented techniques for close-tolerance parts, including the use of non-etch strippers to create an even exchange of removal and build-up so tolerances change very little. No numeric build-up or coating thickness figure is published.
On ultraviolet exposure, the page states that Du All has developed a process letting its Type II anodized parts withstand UV rays for an extended period compared with the industry standard, but is explicit that Type II Anodizing is not intended to hold up to UV rays over an extended period of time.
These are the shop's general process descriptions. None of them is a conformance guarantee for a specific part; a customer needing a stated hardness, thickness or spec result should confirm it with Du All.
