Steel Security Fencing systems consist of modular open grille or fixed louver fencing panels, gates, posts and hardware. Fence panels are fabricated from electro-forged steel. Posts are manufactured of flat steel bars or square steel tubes. Steel bars have a yield strength of 36,000 psi and tensile strength of 58,000 psi. The steel fencing, gates and posts are hot dip galvanized after fabrication, then polyester powder coated to one of 15 standard colors.
