Galvanized Chain Link Fence Framework manufactured and distributed by Merchants Metals
GALVANIZED FRAMEWORK
LG-20 LG-40 Schedule-40 Square Tubing

LG-20 fence framework is engineered to be the perfect solution for industrial, commercial and recreational fencing applications where long-lasting, high strength fence posts, rails and gates are required or specified, but schedule 40 strength is not required.

High strength LG-20 out performs hot-rolled mill structural pipe in these applications and is a substantially lighter product, resulting in important freight and handling savings to fence suppliers and installers

 LG-40 is manufactured with cold-formed steel which provides a high yield/tensile strength, followed by a uniform triple layer of corrosion protection. LG-40 meets or exceeds ASTM F 1043, Type B for strength and protective coatings.

The high yield strength steel and the triple coat of locked-in protection, results in pipe that not only out performs Schedule 40 pipe in strength and corrosion resistance, but maintains its lustrous appearance in all climates and under the most severe atmospheric conditions.
