Peel the posts and braces to remove all outer bark and all inner cambium bark, except an occasional strip of inner bark may remain if not over 13 mm (1/2 in.) wide or 75 mm (3 in.) long. Trim knots flush with the side, remove spurs and splinters, and cut ends square. The small end of round line posts and braces shall be between 90 and 115 mm (3.5 and 4.5 in.) in cross sectional dimension; the small end of intermediate braced posts shall be between 140 and 165 mm (5.5 and 6.5 in.) in cross sectional dimension. The allowable taper from end to end of round posts and braces shall not exceed 38 mm (1.5 in.). Pressure tre at posts and braces according to Section 718. Treat all posts and braces with the same type of preservative. When pressure treated materials have been damaged or when it has been absolutely necessary to cut or bore into them, after delivery to the job sit e, carefully field treat all exposed untreated wood with preservative applied either by thorough swabbing or by an approved bolt -hole treater. Corner, end, pull, line, brace, and gate posts shall be of the type, size weight, and length shown on the plans.
724.03.02 Metal Posts. Steel pipe posts shall be Class 1 or Class 2 and conform to the following:
