Exotic materials, moving/machined parts, complex construction and assurance of quality compliance may preclude some general fabrication workshops/companies from involvement in projects however A&J also specialise in high integrity, high quality fabrications, manufactured to stringent standards with full traceability, quality plans, third party inspection etc.

Recent projects have included Biomass and LowNOx burner units for coal fired power stations and Magnox boxes for the nuclear industry.

Materials of construction for these items have included:

Stainless Steels 304, 316, 410 and 253MA.
Inconel® 600
SA297 Grade HE Cast Steel

Specialist processes for overlay welding of Inconel® and wear resistant hard facing materials have also been developed and used.
