The six joint groups for seasoned (dry) timber are JD1 (highest) to JD6 (lowest). 88 indicates the timber is non-structural so does not have a joint group; indicates that density data were not available. Joint groups for unseasoned (green) timber (J1 to J6) are given only where published, basic density data were available. Structural grading WoodSolutionsStructural grading is the process by which timber is sorted into groups - or stress grades - with ideally, similar structural properties in each group. Inevitably there is a very substantial range of properties within a group and significant overlap in properties between the groups. TECHNICAL DATA SHEET ISSUED BY TIMBER Structural timber is graded into categories (stress grades) which can be used to determine member sizes. The stress grade will depend on the natural properties and characteristics of the species (e.g. density, knots, sloping grain). Stress grades for hardwoods and some softwoods are designated by an F number (F5, F14, F17, F27 etc.).
All timber species graded for structural purposes are classified into strength groups. Because most species become stronger when they are seasoned, there are two sets of strength groups one for green timbers, ranging from S1 (the strongest) to S7; and one for dry timbers, ranging from SD1 (S for strength, D for dry) to SD8. Visual stress-grading WoodSolutionsSimilarly, seasoned mountain ash belongs to Strength Group SD3 and when a particular piece meets the visual requirements for Structural Grade 1, it is assigned a stress grade of F27. The table below is taken from the visual grading standards AS 2082 and AS 2858, and illustrates the sorting system appropriate for use with visually graded timber. strength of timber, strength of timber Suppliers and offers 1,175 strength of timber products.

Jun 18, 2015 · Stress grades are issued in conjunction with strength grades. Unseasoned timber is graded from S1 through S7 with S1 being the strongest. Seasoned timber is graded from SD1 through SD8 with SD1 being the strongest.
