Material
1.1 GRADE
DuraGal angles,channels and flats are manufactured by a cold forming process which ensures that it complies with the requirements shown below
section	Actual thickness             t                 mm	Grade	Minimum   Yield     Stress         Mpa	Minimum Tensile Strength   MPa	Minimum Elongation as a proportion of Gauge Length of 5.65                 %
Flats	t≤6.0     t>6.0	C400LO     C350LO	400             350	450       400	20                           20
Angles and Channels	t≤6.0         t>6.0	C400LO     C400LO	450           400	500         450	16                             16
DuraGal profiles comply with the requirements of steel type 7B in Talbe 10.4.1 of AS4100.
LO indicates that DuraGal profiles have Charpy V-notch impact properties as specified in TS100[11]. Table 10.4.1 of AS4100 Steel Structures permits impact tested LO grades to have the following minimum servicetemperature:
	Actual thickness   mm	Lowest one day mean ambient Temperature         ºC
	t≤5	-30
	5<t≤10	-20
1.2   SURFACE FINISH
A minimum of 100g/m² coating of zinc is applied by in-line galvanising to a mechanically(shot blasted)and chemically cleaned bright metal(AS 1627.4 Class 3.0) surface. A clear polymer barrier coating protects the protects the galvanising prior to fabricartion.
1.3 SIZE RANGE
	Equal Angles	Unequal Angles	Channels	Flats
	30x30 to 150x150	75x50	75x40 to 300x90	50to300
