Steel material for fence panels and posts shall conform to the requirements of ASTM A653/A653M, with a minimum yield strength of 45,000 psi and a minimum zinc (hot -dip galvanized) coating weight of 0.90 oz/sf, Coating Designation G-90. B. Material for fence pickets shall be 1" square x 14 Ga. tubing. The cross sectional shape of the rails shall be steel channel, with the outside cross-sectional dimensions of 1.75" x 1.75" x 1.05". Picket holes in the rail shall be spaced 4.715" o.c. C. Line and corner posts shall be a minimum of 3" square x 12 Ga. D. Gate posts to be a minimum of 4" square x 11 gauge for gate widths up to 4'-6". Gate posts to be minimum 4" square x %4" wall where gate leaf width is from 4'-6" and less than 7"-6". Gate posts to be minimum 6" square x Y4" wall where gate leaf width is 7'-6" and wider. Gate post size to be same on both sides of gate. Grout solid all hinge side gate posts at all 4" x'/4" and larger posts. E. Provide all gates with a minimum of 3 -heavy duty barrel hinges per leaf. F.
