Surface treatment companies · Manufacturing
Be the specialist a design engineer finds when the drawing says anodise or passivate.
A design engineer at an electronics enclosure maker has finished a drawing with a note that reads hard anodise, black, and does not know who in the city does it. The engineer searches the process name, calls two shops and sends a drawing to the one that asks sensible questions about alloy and thickness.
Scope, fee, reporting and term are agreed in writing after we have read your brief and spoken to you.

In one paragraph
Surface treatment companies change the surface of a metal part through processes such as anodising, phosphating, passivation, black oxide and pickling so it resists corrosion, wear or heat. Marketing makes you the specialist that engineers search for by process name. Sales turns a drawing note into a trial lot, a documented process and, once approved, repeat lots.
Surface treatment work is specified, not shopped for. The process name sits in the drawing note, so the buyer starts from a specific method and looks for a shop that does that method well, with the paperwork their customer will ask for. A page for each process, with the alloys, sizes and checks stated plainly, gives the engineer a shop to call.

How buyers decide
How surface treatment companies are chosen.
Buyers are design engineers, quality heads and purchase managers in electronics, aerospace-linked, defence-linked, auto, tooling and consumer product firms. They search for the process by name along with a location. They then check which alloys you treat, which size range your tanks take, the thickness and colour options and whether you can supply a test report.
Some buyers send a trial lot to see consistency before a drawing is released for supply. They look at dimension change after treatment, uniform colour, absence of staining and packing quality. Larger firms ask for process records, customer approvals you already hold and traceability of lots.
Once a surface treater is approved for a part family, the engineer has little reason to look elsewhere for the next part until a quality problem or a missed schedule.
The problem
What usually goes wrong for surface treatment companies.
What owners tell us on the first call, in their words.
“We do many processes but the website lists them as one line”
Anodising, phosphating, passivation and black oxide are all described as surface solutions, so a search for any of them misses us.
“Engineers cannot tell what alloys and sizes we can take”
Tank size, alloy limits and thickness ranges are in our heads, so every enquiry becomes a call.
“We are one of many with a tank and a price”
Buyers see a list of surface treaters and compare only on rate per piece.
“Approval trials go silent”
After sending a sample lot, we hear nothing while the engineer waits for customer clearance.
“Quality documents are rebuilt each time”
Process steps, test records and certificates of treatment are assembled for each new buyer.
“We cannot show work for confidential sectors”
Our best parts are for defence-linked and electronics clients who do not allow names or photographs.
What we do
What we do for surface treatment companies.
Everything included for surface treatment companies.
A page for each process
One page each for anodising, phosphating, black oxide, passivation, pickling and conversion coating, with alloys, size range, thickness and colour options clearly listed.
A capability sheet by alloy and size
A single sheet that lists the alloys, tank sizes, maximum part lengths, finishes and test checks you can deliver.
Process and certificate pack
A pack with your process flow, the checks and records you keep, and a sample certificate of treatment, prepared with your quality person.
Trial lot tracker
A record of each sample lot with the engineer, part, process and the customer clearance it is waiting on.
Anonymised work write-ups
Descriptions of part families such as enclosure panels, camera housings or tool components, giving the problem and the process, without names or photographs that would breach confidentiality.
Enquiry intake form
A short form asking for alloy, process, thickness, colour, size and quantity, linked to your WhatsApp.
How the result is measured
- Enquiries by source and process
- Enquiries that gave alloy and size
- Trial lots started against regular orders won
- Approvals in progress
- Repeat orders from approved parts
- Treatment certificates issued with lots
Recorded as a baseline before work starts, so every later report has an honest comparison.
Every service, written for surface treatment companies
Each has its own page: what it involves for surface treatment companies, what you get, and what it is measured on.
- Lead generationBring in enquiries that already name the alloy, the process and the lot size.
- SEORank for the process name written in the drawing note, not for surface finishing.
- Local SEOAppear in the map result when a buyer nearby searches for your process.
- Social media marketingShow the tank, the rack and the finished lot to engineers who rarely see them.
- Content marketingAnswer the engineer's questions about alloy, thickness and colour before the call.
- Buyer personasKnow whether you are writing for the designer, the quality head or the purchaser.
- CRMKeep every enquiry, trial lot and approval in one place a supervisor can read.
- Follow-up systemsChase the quote, the sample lot and the approval before the engineer forgets you.
- WhatsApp marketingTake drawings, photographs and quote questions on the channel the buyer already uses.
- Digital marketingPut search, content and follow-up to work as one system for the drawing note.
- WebsiteBuild a site where an engineer finds the process, the alloy and the form in one visit.
Worth a page and a campaign of their own

Priority campaigns
Campaigns for what surface treatment companies most want to sell.
Each one planned around when your buyers decide, and measured against the baseline.
Process-name search campaign
Search ads and pages for the specific processes you run, such as hard anodising or stainless passivation, targeted at your region.
Electronics and enclosure maker outreach
A note and capability sheet to makers of electronic housings and heat sinks about anodising options and colour consistency.
Stainless equipment passivation campaign
Outreach to food, dairy and pharma equipment fabricators about passivation and pickling after welding.
Fastener and hardware black oxide campaign
A page and message for fastener and tool makers about black oxide and phosphating for steel parts.
Approved-vendor record update
A refreshed set of process records and treatment certificates for customers who hold you on an approved vendor list.
Beyond search
Where we reach buyers of surface treatment companies, beyond Google.
Search matters, but it is rarely the only way this industry's buyers find a supplier.
Design and manufacturing engineers
The engineer who writes the drawing note. Makers of enclosures, instruments, tools and components near you are approached with a page named for the process on that note.
Stainless and process equipment fabricators
Weld seams on stainless tanks and pipework discolour and need pickling and passivation before the equipment ships. That is the one-line pitch to the fabrication head.
Fastener, tool and hardware makers
Steel parts leave the machine bare and rust in transit. Black oxide, phosphate and an oil film are the answers a tool or fastener maker asks about.
Machine shops
A job-work machine shop that sends aluminium and steel parts out for different processes would rather deal with one source for both.
Electronics and instrument firms
Anodised housings and front panels must match in colour from one batch to the next, and the buyer checks sample against sample.
