In this article R. G. S. GILL summarises the use of timbers in two sets of tables. Table I lists both imported and homegrown timbers grouped roughly according to colour, and specifies their common uses and properties. The remaining tables deal with commercial grades for a variety of end uses, commercial grades of plywood, and different qualities of particle board. The tables are preceded by extensive explanatory notes.

The original concept was aimed at repairing historic structures. However, the technology is increasingly being used for repairing modern materials...
Adhesives are widely used in non-structural applications such as furniture manufacture and joinery. They are also used in the manufacture of panel products such as plywood, particleboard, fibreboard and oriented strandboard (OSB), of which some grades are used structurally.
Glulam and structural timber composites such as cross laminated...
