Color Center

Context

Color Center is a contract coater in Bursa that applies electrostatic powder coating and industrial finishes to metal parts at two plants, NOSAB and Alaaddinbey. Its customers come from automotive, white goods, furniture, machinery, facades and electrical panels, and the person reading the site is usually a buyer or a quality engineer.

I built the company's first site in 2023: a Turkish-only, 19-page build on Bootstrap and jQuery. In 2026 I rewrote it from scratch. The goal was for the site itself to answer what a technical buyer asks before requesting a quote: capacity, process, colour and certification.

Approach

• Structure follows the buyer's questions. Content is split into eight menu groups: Corporate, Applications, Technical, Facilities, Quality, References, Knowledge Centre and Contact.
• Every page in two languages. Turkish and English pages each live at their own localised URL, and the language switch lands on the same page in the other language.
• The material is the visual language. The homepage opens on a RAL fan deck rather than a photograph, and each application card carries its own RAL colour.
• Claims controlled from one setting. The ISO 9001 certificate's expiry date lives in a single setting; when it lapses, certificate claims disappear from pages, the FAQ and the structured data together.

Highlights

• 96 URLs: 48 pages × 2 languages, with legacy addresses permanently redirected to their new pages.
• Quote form: 13 fields including RAL code, gloss, indoor/outdoor use and line preference; reCAPTCHA, KVKK consent and submission without a page reload.
• RAL chart: 63 colours in 9 groups.
• Knowledge Centre: 7 technical articles, a 10-question FAQ and a 10-term glossary.
• Technical capacity: Both plants' floor area, conveyor length, oven and hanger capacity in a single table.

Technical foundation

• Core: A PHP application with a single entry point and no framework or database. All 48 routes and their localised slugs sit in one route table, rendered by 33 page templates and 6 components. No build step.
• Content: Kept in PHP data files and two language files (100 keys per language).
• SEO: Canonical, hreflang (tr, en, x-default) and OpenGraph on every page. Structured data per page type: Organization, LocalBusiness, Service, FAQPage, DefinedTermSet, Article and BreadcrumbList. The sitemap and llms.txt are generated from the same route table.
• Performance: The site's only JavaScript file is 2.8 KB compressed and deferred. Fonts are self-hosted; images are WebP with JPG fallbacks and explicit dimensions; static files are cached for a year.
• Forms: Server-side validation, a reCAPTCHA check and delivery over SMTP with PHPMailer.

Outcome

The rebuild went live in September 2026. The site now presents capacity, process, colour and quality information in two languages, backed by structured data that search engines can read.
