Warmlock Galvanized Steel Quilting Pins / Copper Plated Quilting Pins / Nickel Plated Quilting Pins are mainly manufactured from mild steel, carbon alloy steel, to attach insulation layers to metal surface, involved a lot in HVAC duct lining, air ducts, shipbuilding and maintenance, and various removable or reusable insulation covers and jackets on heating equipments.
Warmlock Galvanized Steel Quilting Pins / Copper Plated Quilting Pins / Nickel Plated Quilting Pins have a cup head in diameter of 30mm (ie,1.18 inches) that is easy for welders to locate during installation. And the cup heads have an upturned bevelled edge that protects the insulation surface from cutting when the quilting pins are pushed to pierce through the insulation layers during installation. Also Warmlock has specifically designed the manufacturing technique to ensure the pins to stand firmly and perpendicularly on the head base, unlike quite some of quilting pins in the industries, whose pin parts come loose easily out of the head bases when being held to shake in cross directions, that lowers efficiency when installation or fabrication, even leads the product fail to work. Warmlock Galvanized Steel Quilting Pins / Copper Plated Quilting Pins / Nickel Plated Quilting Pins perform excellent on this precision point.
