Sag Rod (Thickness- 10mm / 12mm)

A rod for preventing the sagging of an open-web steel joist that is used as a purlin with its depth at right angles to a roof slope. All SAG rods are commonly available in plain steel, hot-dip galvanized, Yellow Zinc and zinc plated. Plain finish all thread rod is often referred to as "black" and it is raw, uncoated steel. Kapson thread rods that will be exposed to the outside elements may need to be hot-dip galvanized to prevent corrosion. Zinc plating can also be used as a corrosion-resistant coating, though a hot-dip galvanized coating will provide greater corrosion-resistance. Zinc plating is commonly used for aesthetic purposes since it can be plated in multiple colors and provides a consistent and shiny coating. For other types of coating as per client's requirements.
