General Specifications
Standard Sing Core Hot Rolled Steel Wall Panels are manufactured with patented Sing Core material as the base interior substrate of the wall panel. The Sing Core substrate material is created using a vertical grain natural wood torsion box design while the traditionally empty voids are filled wall to wall with recycled foam. The foam material is available in various forms depending on your specification. The default is recycled EPS foam. Natural wood lock blocks can be positioned at locations as necessary for locking mechanism placement or as anchor points. The core material is framed by 1-inch T-slot stiles and 1-inch natural rails wood for finishing strength and attaching hardware. The torsion box is completed by adhering 16 gauge hot rolled steel as exterior material (skin) according to your specifications.
Wall Panel Surface Material
The wall panel surface material is made of 16 gauge hot rolled steel unless otherwise specified. Bonding agent used in adhesion of the entire composite material is formaldehyde-free.

Every Sing Core manufactured wall panel is unfinished (unless specified otherwise) and is guaranteed for 10 years for structural integrity.
Detailed Specifications:
Scope: Subject to local building codes, the standard Sing Core wall panel is intended for use in:
- Lighter use industrial building and factory, hotel and retail sales building interior applications
Product Description: 1.132-inch hot rolled steel wall panel manufactured by Sing Core
- Wall component includes unfinished wall panel only
Wall Panel Materials: Sing Core wall panels are manufactured using Eco-friendly cold-press process. Composite materials include:
Sing Core vertical wood-grain torsion substrate filled with recycled EPS foam- Core material is framed with T-slot stiles and wood rails
- Facings are 16 gauge hot rolled steel
- Formaldehyde-free bonding agent is used for adhesion of all components
T-slot Stiles
T-slot consists of an extruded aluminum square T-slot profile with four open T-slots, one on each face. The profile has align-a-grooves to assist in aligning connecting profiles. The profile is compatible with 10-series T-slot fasteners. The four open T-slots enable access from any direction and are useful for joining hot rolled steel wall panels securely and accurately.

Interior Blocking: Solid wood implants can be inserted as lock blocks or anchor points. Also additional stiles (T-slot or vertical wood implants) or rails (horizontal wood implants) can be positioned at any desired location inside the wall panel. (Note: Depending on your expectations, solid wood implants should be supported by at least 12 inches of Sing Core material to maintain true flatness.)
Delivery: Reasonable care is taken to ensure safe transportation of your Sing Core wall panels from factory to your location including proper crating to protect the natural beauty of your wall panels during transport.
Storage and Protection: Store your Sing Core hot rolled steel wall panels in an upright position and allowed to acclimate to room temperature following shipment receipt or prior to finishing or installation.
Preparation: Per manufacturer’s specifications, ensure that openings or attachment walls are constructed plumb, true and level prior to installation. Select fasteners of adequate type, number and quality to assure proper function.
Installation: Installer shall be specialized in the installation of the type of work that is associated with the project and will comply with manufacturer’s installation policies and procedures to ensure proper end use.
- Verify that attachment, hinging and latching assemblies operate freely and correctly
Finishing: The finishing of the Sing Core standard hot rolled steel wall panels is the responsibility of the client due to the product being delivered in unfinished condition unless specified otherwise in writing fro use in interior applications only. Any exterior use must be approved in advance to avoid warranty exception and sealing must be in accordance with manufacturer’s specifications to protect against a variety of environmental conditions as necessary. In reference to exterior applications:
- Seal all 6 surfaces with two coat minimum on operable panel(s)
- Finishing or re-finishing must be completed following acclimatization and installed within 7 days
- Avoid finishing after rain (or damp) or during periods of higher than average humidity
- At least once a year, conduct periodic inspections of coating to ensure no wall panel components are exposed
- Reseal the surface as necessary
Machining: Sing Core hot rolled steel panels are easy to work with in the metal shop for machining or on-site for finishing, and fastening.
Strength Performance: Patented Sing Core has an unsurpassed strength as compared to other lightweight substrate materials tested at 660 PSI (based on 2″ x 2″ grids and 3/4″ thick) for superior structural integrity and is resistant to warp, twist and crack when compared to other materials.
Light Weight Performance: Sing Core weighs much less than other traditional building materials, as much as 50% less; or more, as little as 4 lbs. per sq. ft. yet sustainable and true green technology.
Insulation Performance: Standard Sing Core wall panels feature built-in insulation value with an R3 (can be upgraded to to R6.5 or more) rating per inch, depending on architect’s specifications.
Acoustical Performance: Sing Core standard wall panels have a natural sound-deadening quality for noise control. Standard sound transmission class (STC) is 30*. Additional noise control specifications can be met at the behest of the customer or designer and must be noted in advance.
Eco-friendly: Sing Core is manufactured using natural wood fibers, no formaldehyde, or toxic chemicals, is created using less energy than any other core material with little or no waste. The structure of Sing Core is 100% renewable (nature-grown) clean fiber and/or recycled material.
Warranty: Sing Core standard wall panels are come with a 10-year warranty, while professional manufactured wall panels can be structurally guaranteed and warp-free for 50 years under normal conditions.
Custom-cut Window/Lite Openings: Lite openings for glass inserts can be custom cut per your specifications (drawings above show examples of standard openings) for glass insertion.

* Note: STC rating varies according to size, thickness, skin, and other factors. Sing Core does not rate doors, although we are fortunate enough to have one of the best sound testing labs in the world, here in the Pacific Northwest. If you require a specific STC rating, Sing Core can build a door to your architectural specifications and have the resulting door tested at our rating facility for an official rating.
