These custom stamped L brackets are made using low carbon steel material with zinc plated finish. .125" thick material is used and the outside dimensions are 3/4" for each leg, as well as the width of the bracket length itself. Production takes place in the USA and we typically run approximately 10,000 pcs at a time for this stamped part. Our customer uses it in combination with two other custom stamped brackets used to assemble decorative paneling.
