Questions about the Timber poster

What’s on the Timber poster?

A definition and 6 facts worth remembering. Timber is graded because its strength depends on knots, slope of grain, density and moisture content. Strength along the grain far exceeds across it; Moisture content changes strength and size; Visual and machine grading both give classes; Softwood classes C, hardwood classes D; Load duration changes the design capacity; Service class reflects humidity in use; Common structural softwood — C16 or C24; Heated interior moisture — Around 8 to 12%; Timber built in wet and dried in service will shrink, twist and split.. Educational reference. Strength classes, service classes and load duration factors come from the timber design code.

Who is the Timber poster for?

Timber belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning civil materials can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Timber poster?

Specifying structural timber, or judging why a member has moved. A wall chart earns its place by being glanceable from where the work is happening, so Timber belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Timber?

Aggregates, Bituminous Materials and Cement Types sit alongside Timber in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AggregatesBituminous MaterialsCement Types

Is the Timber poster free to download and print?

Yes. Timber downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Timber poster print at?

Timber is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Timber loses nothing.Printing guide
