Powder coated strap and method for making same
View Patent ↗A corrosion-resistant coated strap is formed from an elongated metal strap base element having a width and a thickness and defining first and second sides and a pair of edge regions. A coating is applied and cured onto the base element. The coating has a substantially consistent thickness at the first and second sides and at about the edge regions. A method for making the coated strap includes providing a metal strap and conveying the strap through a coating apparatus. A powder is electrostatically applied on the first side of the strap, which covers the first side and the opposing edges. The powder is applied on the second side of the strap, covering the second side and the opposing edges. The powder is melted to form a flowable material and is cured on the strap. The coating method is carried out in an in-line strap manufacturing process.
1. A corrosion-resistant coated and cured strap comprising;
an elongated metal strap base element, the metal strap base element having a width defining first and second sides and a thickness defining a pair of opposing edge regions; and
a melted and cured powder coating on the base element, the coating having a first substantially consistent thickness at the first and second sides and a second substantially consistent thickness at the edge regions, the first and second thicknesses being different from one another, wherein the coating has a greater thickness at about the pair of opposing edge regions and about regions of the first and second sides adjacent the pair of opposing edge regions than on the first and second sides to define a dog-bone profile.
2. The corrosion-resistant strap in accordance with claim 1 wherein the first thickness of the coating is about 0.2 thousandths of an inch to about 5.0 thousandths of an inch.
3. The corrosion-resistant strap in accordance with claim 1 wherein the first thickness of the coating is about 0.6 thousandths of an inch to about 12 thousandths of an inch.
4. The corrosion-resistant strap in accordance with claim 3 wherein the first thickness of the coating is about 0.8 thousandths of an inch.
