Product Description
Item: Steel perforated sign posts
Steel Grade: Q235B steel
Surface Treatment: Powder coated
Wall Thickness: GAUGE 12
Hole: 7/16" diameter holes on 1" centers, full-length and 4 sides punched, 1/2" from one edge of square tube to the first hole center.
Specifications
MATERIAL
Tubing with plain finish is rolled from 12 gauge (0,105 U.S.S. Gauge) and 14 gauge (0,075 U.S.S. Gauge) hot rolled steel, Q235b. Galvanized finish, average minimum yield strength after cold forming is 60 000 psi.
GALVANIZATION
Galvanization shall conform to specification ASTM A653 G90 (275g/m²). Corner weld is zinc coated after scarfing operation.
TOLERANCES
Wall thickness tolerance:
Permissible variation in wall thickness is + 0,011, -0,005 inches.
Tolerance on size: Nominal outside dimension (inches)
Outside tolerance for all sides at corners (inches)

* Tubing may have its sides failing to be 90° to each other by tolerance listed.
**Twist is measured by holding down the edge of one end of a square tube on a surface plate with the bottom side of the tube parallel to the surface plate and noting height that either corner on the opposite end of the bottom side is above the surface plate.
Convexity and concavity: Measured in the center of the flat side, tolerance is ±0,010 inch applied to the specific size determined at the corner.
Straightness tolerance:Permissible variation in straightness is 1/16” in 3 feet.
Telescoping: Using 12 gauge or 14 gauge square tube, consecutive size tubes shall be cleaned of galvanization burrs and shall telescope freely for ten feet.
Hole tolerance: Tolerance on hole size is ±1/64” on a 7/16” hole size. Tolerance on hole spacing is ± 1/8” in ten feet.
