S-20, S-24 Features and Options

Raynor SteelForm S-20 and S-24 sectional ribbed commercial doors are available with numerous features and options, including those listed below.

Durable Construction

Constructed with stainless steel rivets and roll-formed tongue-in-groove meeting rails for maximum structural integrity, S-16, S-20, S-24, and S-24C doors are built to withstand heavy use.

Rugged Hardware and Springs

Your SteelForm door comes packaged with the right combination of hardware, track, and springs to precisely match your door’s size and application and provides years of reliable service.

Decreased Energy Costs

SteelForm doors help you reduce energy costs with a U-shaped, vinyl bottom weatherseal secured by a sturdy aluminum retainer.

Header Seal

Flexible, EPDM rubber flap header seal on S-16, S-20, S-24, and S-24C reduces air infiltration and energy costs by sealing the top of the door against the header.

Jamb Seal

Jamb seal also helps to reduce air infiltration and decrease energy costs by sealing the side of the door when closed. Available in EPDM rubber or flexible vinyl flap.

Section Joint Seal

SteelForm doors are available with a neoprene foam rubber section joint seal to help prevent airflow between sections.


Doors are available with energy-saving insulation. Choose from white impact-resistant (shown) or steel (26, 24 or 20-gauge) back covers.

Secure Locks

In applications where control and access are important, choose from a variety of locking options to help keep your building secure. Locks come in both inside and outside variations.


The EnduraCote hardware system comes with springs, track, and hardware that are powder coated to provide a clean, finished look and maximum protection against rust.

Choice of Windows

Select either 24″ x 8″ or fullview window sections. Choose from a variety of glass, insulated glass, acrylic and polycarbonate styles to suit any application.

Removable Center Posts

Carry-away, swing-up options available for extra-wide openings. Ideal for agricultural or airplane hangar applications.

Customized Track and Hardware

Track systems are supplied to fit special clearances, inclines or contour applications. Hardware and track systems can be designed to fit any need. Additional trussing is available for special wind loading applications.

Carbon Monoxide Vent

Allows you to channel fumes to the outside when the SteelForm S-16 door is closed. Available in a variety of sizes.

High-cycle Counterbalance System

For reliable operation in high traffic areas, choose high-cycle torsion springs with 25,000; 50,000 or 100,000 cycle life. For reduced maintenance and ultra-smooth operation in heavy-use applications, choose a weight counterbalance system.
