The British Standards 'Code of practice for the use of masonry - Part 3: Materials and components, design and workmanship' BS5628-3:2005 implies that the lintel material/coating specifications should be limited to austenitic stainless steel in two distinct circumstances.
a) Non-aggressive Environment
Buildings exceeding three storeys in a non-aggressive environment. The material coating specification for products in contact with or embedded in an outer leaf of an external cavity wall or a single leaf external wall should be austenitic stainless steel.
b) Aggressive Environment
Buildings located in an aggressive environment (e.g. coastal sites). The material coating specification for products in both leaves of external walls should be austenitic stainless steel.
The outstanding anti-corrosion properties of stainless steel also make it suitable for specialist laboratory or medical applications, hospitals, residential care homes, schools and prisons where the whole life expectancy and maintenance programme become key design considerations.
