The Standing S Cleat roll forming machine features 12 forming stations designed to shape sheet metal into a standing S cleat profile. This profile combines a traditional S cleat with a standing seam, providing increased strength and rigidity.
Built with high precision needle bearings, heavy-duty chassis plate, hardened and ground roll shafts, and a welded steel frame with premium protective coating, this machine ensures long-lasting performance and reliability.
Application
The Standing S Cleat is similar to a Flat S Lock but includes a 1" standing seam, which adds extra strength to ductwork. It is commonly used when duct width exceeds 20 inches.
Like Flat S Lock, it is applied to the top and bottom of duct connections, while drive cleats are used on the shorter sides.
Usage in Duct Systems
Rectangular ducts have two long (horizontal) and two short (vertical) dimensions. As duct width increases, shops typically switch from Slip & Drive systems to Standing S Lock or TDC systems for better structural performance.
Standing S Cleat is usually applied when widths exceed 24 inches and can be used up to approximately 30 inches before switching to other connection systems.
Production Notes
This profile requires at least 10 roll forming stations and is not produced on the same machine as Flat S Lock. Due to higher production costs and material preparation requirements, many shops choose to outsource Standing S Cleat production.
However, shops equipped with this machine can efficiently produce cleats in-house, reducing waste and improving workflow—especially in facilities using advanced coil lines and plasma cutting systems.
