High Security Steel Doors
Our high-security steel doors are custom-made to meet your requirements. We offer a wide range of security options rated from RC2 to RC5. Our products can be manufactured to be bulletproof up to FB7 rating and fire resistant up to Ei60.
Steel Doors and Glazing Systems, Made to Measure
TDS supplies two distinct categories of bespoke steel products — CE-certified security doors and slimline steel glazing systems. Both are manufactured to order and available for supply worldwide, with installation in Ireland.
CE-certified high-security steel doors
Our high-security steel doors are manufactured to EN 1627 and rated from RC2 to RC5. Fire-resistant options are available up to Ei60, and ballistic protection up to FB7. These doors are supplied to government, military, banking, and detention facilities — as well as private clients with elevated security requirements. Full compliance documentation and confidentiality are standard.
Slimline steel glazing for interiors and facades
Our internal steel doors and partitions use the OC Slimline system — narrow-profile steel frames designed to divide space while maximising natural light. For external steel glazing, we supply certified systems from Jansen, Forster, and Ottostumm, covering facades, curtain walls, and entrance systems with full thermal performance credentials. Finishes range from RAL colours to materials suited to heritage and listed building projects.
Working with architects, surveyors, and private clients
We work directly with architects, quantity surveyors, interior designers, and private clients across Ireland and internationally. Our team handles the full process — from initial specification and drawings through manufacturing, delivery, and installation. All products are made to measure.
