Pittsburgh S-cleat C-drive machine plus Flanger attachment

The HVAC Multi-Function Lock Seam & Cleat Forming Machine (4-in-1) is an industrial sheet metal processing unit designed for the production of duct connection profiles used in heating, ventilation, and air conditioning (HVAC) systems. This machine combines several essential forming operations into one compact system, allowing manufacturers to produce multiple types of duct joints with high precision, stability, and efficiency.

What This Machine Does

This equipment is used in HVAC duct fabrication lines to form the connection edges that allow duct sections to be assembled into complete ventilation systems. Instead of using several separate machines, this unit integrates multiple forming functions into one workflow.

• Forms S-cleat profiles for duct edge connections
• Produces Drive cleats (C-cleats) for overlapping joints
• Creates Pittsburgh lock seams for airtight rectangular ducts
• Forms seam locks used in round duct fabrication
• Includes flanger attachment for male flange formation

Who This Machine Is For

This machine is designed for professional HVAC manufacturers and metal fabrication workshops that produce ventilation systems for residential, commercial, and industrial projects. It is ideal for businesses that need to increase productivity while reducing equipment costs and workshop space requirements.

• HVAC duct manufacturing companies
• Sheet metal fabrication workshops
• Ventilation system producers
• Roofing and metalworking facilities
• Small and medium industrial production lines

Technical Specifications

• Roll-forming speed: up to 36 ft/min
• Forming rollers: 8 pairs in 3 rows
• Material thickness range: 18–26 gauge sheet metal
• Power supply: 110V / 2.2 kW (3 HP), 60Hz, 20A

Key Advantages

This 4-in-1 lockforming machine provides a cost-effective and space-saving solution for HVAC production facilities. It replaces multiple individual machines while maintaining high production quality and operational efficiency.

• 4 functions integrated into one machine
• Reduces equipment investment costs
• Compact design saves workshop space
• Stable and low-noise operation
• Durable industrial-grade construction
• Easy operation with minimal maintenance
• Suitable for both round and rectangular duct systems

Why This Machine Is Important

In HVAC duct manufacturing, proper edge forming is essential for airtight, durable, and structurally stable systems. Without accurate lock and cleat forming, duct connections may leak air, lose pressure efficiency, and require additional manual sealing.

This machine ensures consistent production of high-quality connection profiles, allowing ducts to be assembled quickly on-site with strong mechanical joints and minimal leakage risk.

Pittsburgh S-cleat C-drive machine is a complete solution for duct connection production. It combines multiple forming processes into one unit, making it ideal for HVAC manufacturers looking to improve efficiency, reduce costs, and streamline their fabrication workflow.
