0.42 bmt meaning :

"BMT" stands for "Base Metal Thickness," referring to the steel thickness used in metal roofing and cladding products. The following number, such as "0.42," represents the thickness of the steel in millimetres. In the case of "0.42 BMT," this would indicate that the steel used in the metal roofing product is 0.42 millimetres thick. This thickness is typically used for residential roofing and it is suitable for moderate weather conditions. BMT thicknesses are available in various options, including 0.35, 0.42, 0.48 and 0.60, suitable for different climates and weather conditions.

It is among the world’s most popular metal roofing products due to its high quality and versatility. These corrugated iron roofing panels, or Custom Orb, suit traditional and contemporary roofing projects.

General Info

COLORBOND® roof and cladding sheets are available in various colours to match any building project and are made in Australia using BlueScope steel. Corrugated COLORBOND® is one of the most durable, long-lasting roofing materials available, and it’s virtually maintenance-free. Made from hi-tensile steel, this profile, whilst strong, is also lightweight, minimising sheet damage.

Corrugated sheeting is pierce-fixed, ensuring easy fixing by the conventional method. To provide maximum weather protection, our Corrugated has a 1.5 rib overlap. The wide cover (762mm) allows for quick installation, saving on materials and labour. This versatile profile can be used on a minimum roof pitch of 5 degrees.


Fixings

Here at Metal Roofing Online, we only use and recommend Class 4 screws when installing your roof sheeting, as they last considerably longer in the elements. In a standard roofing application, when fixing to either timber or metal purlins, we have a Multifix screw which is the perfect choice for this roofing iron.
 
When using the corrugated iron sheet in a wall cladding application, there is a choice between 12 gauge x 25 mm timber fix screws when fixing into the timber. Otherwise, ten gauge x 16mm will do the trick when fixing steel. These screws are shorter as they are fixed into the corrugation's pan (or valley). "Cover of roofing sheet": is the measured amount each sheet will cover (including the side lap) when laid in position on the roof. IE, the cover of a corrugated roof sheet is 760mm or .76 metres. Please consider both resistance to wind pressure and foot traffic for roofing spans. 

Please consider a couple of factors when deciding whether you need .42bmt or .48bmt sheets as roof covering:

Your batten spacing and how often the roof will be walked upon
 
The maximum recommended support spacings are based on testing by AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992.

Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from unplanned maintenance).
