This Standard sets out the minimum requirements for natural round treated hardwood corbels, girders and stringers intended primarily for use in heavy engineering projects (e.g., bridges, wharves and large timber-framed buildings). These minimum requirements apply at the time of grading.

This Standard does not cover requirements for strength and dimensions.

NOTES:

1 Requirements for strength and dimensions should be specified separately.

2 Purchasing guidelines are given in Appendix A.
