Principal rafters are the largest form of rafter found at the ends of a roof structure in a timber-framed roof. They are commonly used to carry a purlin and sit directly on a tie beam. Principal rafters run from the roof’s ridge to the wall plate; they’re a little heavier than ordinary rafters, and they’re usually framed into a tie beam at a corner post, story post, or chimney post. The principal rafters, when combined with the principal purlins, constitute a very stable roof construction system. Common rafter InfoCards are updated when new information is available. The date of the last update corresponds to the publication date of the InfoCard and not necessarily to the date in which the update occurred in the source data. Holes and notches in the rafters can only be drilled or cut if they are proven to be adequate by specialised calculations.

Many common, or general purpose, rafters make up each roof. The number of common rafter units needed for each project is mostly determined by the roof’s size and scope, as well as the distance each unit rafter must span. Timber rafters rely on nails or screws for connection.

The examples provided are generic examples and may not apply to the specific substance you are viewing. A substance may have its use restricted to certain articles or products and therefore not all the examples may apply to the specific substance. Furthermore, some substances can be found in an article, but with unlikely exposure (e.g. inside a watch) or with very low concentrations considered not to pose risks to human health or the environment.The EC Number is the numerical identifier for substances in the EC Inventory. The EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). More information about the EC Inventory can be found here. Lean the rafters that have been fastened in against each other. Nothing is holding them up, so your assistant will have to hold them in place. Using regularised UK timber dimensions, it is possible to determine the maximum span of timber rafters subjected to different values of live loads according to BS 5268-7.5.
