duct liner weld pins are specialized insulation fasteners used to secure duct liner insulation and other thermal insulation materials in HVAC systems, industrial ductwork, and acoustic insulation applications. These duct liner weld pins provide strong welding performance, reliable holding power, and fast installation efficiency.
Manufactured from high-quality low-carbon steel or stainless steel, IKING duct pins ensure excellent weld strength and long-term durability under demanding working environments. The sharp pin design allows easy penetration through fiberglass insulation, mineral wool, foam board, and other insulation materials.
Widely used in HVAC duct fabrication, air conditioning systems, industrial insulation projects, and soundproofing installations, our insulation weld pins are compatible with most insulation welding equipment and automated production systems.
Designed for secure attachment to sheet metal surfaces with reliable weld strength and reduced burn-through risk.
Improves installation efficiency in HVAC duct liner and insulation fixing applications.
Available in galvanized steel, 304 stainless steel, and aluminum for corrosion resistance and long service life.
Suitable for fiberglass insulation, mineral wool, foam insulation boards, and acoustic insulation materials.
Custom pin diameters and lengths are available according to project requirements.
