End-to-end fabrication & integration for defence applications

The need to perform at high levels of precision and often in the extreme situations and environments that most military applications are exposed to means that defence contractors demand exacting requirements and optimal standards in design, manufacturing and production.

Sheet metal fabrication for military contracts, therefore, requires a higher level of manufacturing capability than is generally demanded outside the sector. Captec has developed an integrated service from end to end design, prototyping, manufacturing and testing to assembly and delivery, so we can apply the best possible process to specific defence projects.

Captec has built an established reputation as a supplier partner to leading defence contractors, providing a dynamic range of services that combine multiple disciplines, including advanced sheet metal fabrication, precision machining, integration and assembly. In addition to this our paint finishing facility provides a variety of specialist military and aerospace grade coatings and paints, all in accordance with our accreditation to ISO 9001.

Our focus is to help our defence customers achieve greater productivity, higher precision, and better overall performance.
