Timber Development UK are delighted to announce the publication of essential span tables for C16 and C24 timber grades.
Span tables are the most commonly requested form of data we receive from builders’ merchants. Timber Development UK has just published a suite of span tables and they can be downloaded for free from the TDUK website now.
Span tables allow you to calculate the size of a timber member of a particular strength class required for a given span – as well as the maximum spacing between each section or timber member. They help you to choose an appropriate size and stress grade to achieve your spanning requirements.
What do the tables include?
These new tables provide guidance on the loadbearing capacity of timber members to give adequate support to floors, ceilings, and roofs in domestic dwellings. They include tables for:
- Domestic ceiling joists
- Domestic flat roof joists
- Domestic floor joists
- Single span common or jack rafters
Both sets of span tables can be downloaded from our Resources pages:
A comprehensive knowledge library
The span tables are a first taste of TDUK’s forthcoming Knowledge Library, which will be published over the next few months. This will feature 140 Wood Knowledge Sheets, providing members of TDUK with an essential library of information. Whether you are in the Supply, Build or Design sector, the Knowledge Library will provide you with the answers to all of your timber-related questions, and further your understanding of timber construction.
