M METAL (RF55©)

Material Specification

RF55© is manufactured from high tensile steel (min 500MPa yield stress) with a base metal thickness (BMT) of 0.75mm, 1.0mm or 1.20mm. The galvanized coating class is Z275 (min 275g/m2) in accordance with AS1397:2001. Other base metal thickness and coating classes are also available on request, subjected to availability.

BMT（mm）	Steel Grade（MPa）	Zinc Coating Class+	2nd Moment of Area（cm⁴/m）	X-Sectional Area（mm⁴/m）	Weight ( kg/ m² )
0.75	550	Z275	42.82	1248	10.32
1.00	550	Z275	64.57	1664	13.56
1.20	550	Z275	79.42	1997	16.32

+ A zinc coating  of total 275 g/m²  (including both sides) is sufficient for internal floors in a non-aggressive environment, but the specification may be varied depending on service conditions – EN1994-1-1 4.2(3)
