ARCHITECTURAL SPECIFICATION
The roofing and/or wall cladding metal sheets shall be 0.42mm BMT (i.e. 0.47mm TCT) or 0.48mm BMT (i.e. 0.53mm TCT)
MONOCLAD as produced by LCP Building Products Pte. Ltd., with trapezoidal ribs of 29mm high, spaced at 190mm
centres. The effective cover width for the metal sheets shall be 762mm.
The sheeting material shall be ZINCALUME protected steel sheet to Australian Standard AS1397 with a minimum
yield stress of 550MPa (Grade G550), metallic hot-dip coated with ZINCALUME zinc/ aluminium alloy- coated steel
comprising 55% aluminium, 43.5% zinc and 1.5% silicon. The minimum coating mass for the ZINCALUME zinc/aluminium
alloy - coated steel shall be AZ150 (150 g/m2 minimum coating mass) as determined by Australian Standard AS1397.
Wherever applicable, the installation of the metal sheets shall be in accordance to the Installation code for metal
roofing and wall cladding; Standards Australia SAA HB39-1997. The sheets shall be installed in accordance to
manufacturers recommendations. The fasteners used to secure the metal sheets to the supports shall conform to
Australian Standard AS3566 and be compatible with the roofing material used.
Sheets shall be laid in such a manner that the approved side lap faces away from the prevailing weather. A minimum
of 50mm shall be provided for projection into gutters. Flashings shall be supplied in compatible materials as specified,
minimum cover of flashing shall be 150mm.
All sheets shall be fixed in a workman like manner, leaving the job clean and weather-tight. All debris (nuts, screws,
cuttings, filings etc.) shall be cleaned off daily.
COLOUR COATING OPTIONS
Clean COLORBOND pre-painted steel is resistant to dirt
pick-up and staining. The various categories of Clean
COLORBOND pre-painted steel finishes offers excellent
gloss and long lasting life span to the roof and wall
cladding.
The following Clean COLORBOND pre-painted steel
finishes are available:
1. Clean Colorbond Ultra Steel (Used for severe
applications that require premium durability.)
2. Clean Colorbond XPD Steel (Used for moderate/
severe applications that require premium durability.) FLASHING DETAIL
3. Clean Colorbond XPD Pearlescent Steel (Used for When designing the flashing, the rib needs to be taken

Fastener Locations:
- MONOCLAD is usually fixed at every rib on each
batten/purlin, i.e., 4 fasteners per sheet. This enables
maximum performance and efficiency of the roof
system.

Ensure sheets sit correctly before fixing so that the

CONDITIONS
The maximum span charts cover only applications defined in AS1170.2 1989 Section 2 as per the region and
exposures noted on each chart, and of no more than 10m in height, and shall apply only to enclosed buildings of
less than 1000m in plan area. The spans listed are based on the testing requirements of AS1562 for both foot traffic
and wind loadings, and assume both the end and first internal span to be subject to local pressure zone factors.
* : For optimum spanning capacity, end spans are shorter than internal spans in a fixed ratio, (End Span = 0.8
Internal Span). The Internal/End Span combinations shown must only be used in this specific ratio, rounded to the
nearest 50mm.
