Provided below are the most common sizes and load requirements. If the size you require does not appear here, please call our technical team on 1300 885 295. Mascot Engineering will design your multipart and provide the relevant engineering support as needed.
The below table and illustration shows the height and seating depth as well as the width and height of the beam pocket that should be allowed for on-site.
When planning rebates (and prior to construction), we recommend you discuss your requirements with our technical team to ensure the information provided here is relevant to your multipart.
How to choose a multipart
Assuming you require an opening of approximately 2000mm x 2000mm in an area with only pedestrian loads or occasional light vehicle access. After consulting the following charts, a B113 with an internal clear opening of 2060mm x 2040mm is chosen.
Next, we can determine that a B113 has two beams wiht a beam spacing of 660mm, 720mm and 66mm. If you add these three dimensions together, you can see that hte clear opening perpendicular to the beam is the 2040mm dimension. Therefore, the beams span the 2060mm distance.
