35×35mm Steel Aluminum Self-Adhesive Insulation Pins with ±0.1mm Tolerance for HVAC Duct Systems
RongFeng cup-head pin weld fasteners enable secure installation of insulation materials on sheet metal surfaces, particularly in HVAC systems (air ducts) through a single operation. Our specialized welding equipment delivers high-quality welds on sheet metal up to several centimeters thick, featuring long cables and lightweight design for optimal construction site mobility.
The capacitor discharge welding technique prevents overheating marks on the opposite side of metal sheets, while the insulated shank design allows secure fastening of aluminum-faced insulation materials.
