Design & Supply: experts in security‑rated, fire‑rated and slimline doors

For nearly 36 years, Design & Supply has been a trusted UK manufacturer of industrial doors and architectural solutions. We design and fabricate security‑rated steel doors, CE‑marked fire doors (FD30–FD240), flood‑resistant doors, acoustic doors and our sleek Slimline Schüco Jansen range, ensuring each product meets the most demanding commercial and industrial requirements.

Our steel hinged doors offer extended fire ratings and certified LPCB security (LPS1175 SR1–SR4), while the Slimline range delivers slim profiles without compromising safety or energy efficiency. Every doorset can be customised with manual or electronic locking systems, glazed or louvred panels, and hundreds of RAL and BS powder‑coat colours.

We understand that lead time matters, so many standard sizes are available from stock with installation in as little as 10 days. From initial site survey and CAD design to fabrication and nationwide installation, our experienced team provides a comprehensive service.

If you’re looking for custom steel doors in Merthyr Tydfil or anywhere across the UK, Design & Supply offers fast quotes, a price‑match guarantee and full manufacturer assurance. Let us handle your fire‑safety, security or flood‑protection challenges with precision and reliability.
