Specification of square tube fence post 

 Materal
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.
 
Tolerance 
Wall thickness tolerance:
Permissible variation in wall thickness is + 0,011, -0,005 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.

Applications of square tube fence post 
 
Anchor Base

A 3' length of square tubing is driven into the soil to serve as an anchor base. Using either hand or power equipment 1" to 2" is left above the surface. One man working at ground level can safely and easily insert the sign post into the anchor base and bolt in place. Signs can be bolted onto the post before installation.

Yielding Breakaway

A yielding breakaway system is easily created by using an outer sleeve of the next larger size tube than the original 3' anchor base. This additional sleeve, approximately 18" long, provides a double wall thickness to accomplish the breakaway function. When installing in soil, it is advisable to drive the anchor base and outer sleeve together leaving the anchor assembly 1" to 2" above the surface. The sign post is then inserted and bolted into the anchor assembly. Upon impact, the post yields at the top of the anchor assembly, normally leaving it undamaged.

Single Post

The Galvanized square tube fence post may also be installed from a  truck or step ladder simply by driving a single post into the ground, either by power equipment or sledge hammer.
