What MTE does

Mech-Tool Engineering Ltd (trading as MTE) is a UK-headquartered industrial engineering company that designs, manufactures, and installs fire, blast, and thermal protection products for the global energy and defence sectors. Its core technology portfolio spans custom-engineered fire and blast walls, heat shields, blast relief panels and ducts, escape route systems, and acoustic cassettes, alongside a proprietary microporous insulation line marketed under the Mech-Tool Thermal Defence sub-brand for naval, SMR, and nuclear applications. Manufacturing is conducted at facilities in Darlington and Teesside (UK) with a wholly-owned subsidiary, Mech-Tool Korea Inc, in Busan, South Korea, providing Asia-Pacific capacity and local-content compliance.

The company generates revenue through project-based enterprise contracts with operators in oil and gas (offshore platforms, FPSO vessels, processing facilities), naval and defence (vessels, submarines, vehicles), nuclear (SMR developers, plant operators), and offshore wind. Products are custom engineered to individual project specifications with pricing determined through direct quotation, and the firm also offers design consultancy services for fire/blast protection and weight/cost optimisation. MTE holds ISO 9001, ISO 14001, and ISO 45001 certifications, plus Lloyds Register, DNV GL, Cyber Essentials Plus, and JOSCAR registrations, which are prerequisites for participation in marine, offshore energy, and UK defence supply chains. The company was founded in 1969, remains privately held, and employs 251–500 people.
