"The lintels are fabricated from either:
(1) hot dipped galvanized steel to BS EN 10142 :
1991, grade
DX51D, and Z275 or Z600 coating
type, with a minimum yield stress
of 250 Nmm,
and further protected against corrosion* by an
epoxy
or polyester resin coating applied to all external
surfaces of the
lintel to a minimum thickness of
0.025 mm,

or

(2) stainless steel to BS 1449 : Part 2 : 1983,
Grade 304 S15.
