Limitations
For use in wind region Class C2 and up to a maximum ultimate wind
pressure rating as stipulated in Table 5.2 of AS/NZS 4505:2012
(refer also to design criteria on engineering drawings attached)
The use of configurations RC1 – RC3 (as appropriate) only, apply to
this certificate.
This certificate relates to the structural adequacy of the B & D
Windpanel™ reinforced sectional door with vertical braces and
tracklock only. The structure to which the door is attached
including lintel heads, ceiling wind beams and support abutments
shall be assessed and certified independently as required by a
suitably qualified engineer.
The subject doors are rated up to the relevant ultimate design wind
pressures as stipulated in the design criteria of the attached
engineering drawings.
The building certifier or project engineer is to ensure that the site
specific ultimate design wind pressures do not exceed the ultimate
design wind pressure ratings given on engineering drawings.
Alternative design parameters to what are specified on engineering
drawings along with alternative site specific local pressure factors
may be adopted provided the calculated ultimate design wind
pressures do not exceed the pressure ratings given on engineering
drawings.
Doors may be positioned at any location along the building envelope
including all local pressure zones (i.e. corners of buildings) provided
the calculated ultimate design wind pressures do not exceed the
pressure ratings given on engineering drawings.
