PowerPoint Weld pins permanently attach insulation to galvanized steel in the fabrication of ductwork. PowerPoint Weld pins withstand a tensile pull of at least 120 pounds in sheet metal and can be used in conjunction with adhesives on any galvanized sheet metal with lock forming qualities of 26 gauge and heavier.
Composition and Materials
The fastener head, shank and point are manufactured from a special carbon alloy steel. A 1" diameter retaining cap fabricated from cold rolled steel is mechanically affixed to the driven end of the fastener.
PowerPoint Weld pins meet and exceed the latest SMACNA (Sheet Metal and Air Conditioning Contractors National Association) standards, published in their HVAC DUCT CONSTRUCTION STANDARDS 1995, for low and high velocity ductwork. They are used by leading air-conditioning, sheet metal and mechanical contractors for ductwork in commercial buildings.
PowerPoint Weld pins are plated with .0002" to .0003" of zinc and receive a final chromate dip. This plating exceeds current SMACNA standards for corrosion resistance.
The beveled edge retaining cap is sufficient in size and design to depress the surface of the insulation without tearing or cutting it. The cap does not protrude into the air stream to create noise or interfere with air movement in the duct.
PowerPoint Weld pins function properly over normally accepted operating range of temperatures of 32 degrees F to 250 degrees F and are not adversely affected at temperatures of 0 degrees F to 550 degrees F.
PowerPoint Weld pins will not fatigue or be physically affected by vibrations normally found in high velocity air handling systems.
When used as intended, Power Points are non-toxic and safe as defined by current Federal Standards. Safety glasses must be worn when applying fasteners at all times.
