The Interlock Steel Structure System (ISSS Panel is designed and engineered to be load bearing and a fully insulated building component. Designed to allow total flexibility, its uses include walls (internal/external), curtain walls, roofs and floors. The ISSS Panel permits, virtually the construction of any industrial, commercial or residential structure to be erected on a cost effective basis. The structure will be superior in quality and the key factors of the Panel's superiority are its thermal efficiency and the cost effectiveness in erection time.
Each ISSS Panel consists of high density Class A - Urethane blended with a fire retardant additive and bonded between two steel sheets with minimal thermal transfer. The standard Panel width of 24" (60.96 cm.) accepts all routinely used material and meets all load bearing requirements.
The outside walls of a one story building may be routinely completed plumbed and fastened into position in a few hours and completion of the structure may commence on schedule.
Plan layout dimensions will be to standard components or, may be customized to exact dimensions ordered. The cost effectiveness of the ISSS superior Panel and usually ac acquired builder preference after hands on experience. In construction of curtain walls the panel application is superior in both engineering integrity and aesthetic applications.
A complete structure may be finished inside and out with standard code approved finishes. On the inside, drywall is a usually preferred finish in many countries but any finish may be used with the correct application method used.
On the outside, single course brick veneer, wood, aluminum or vinyl siding are routine. Modern stucco type finishes are popular in many areas.
Strength & Insulation
The basic ISSS Panel is designed in units that are 24 inches wide and multiple feet in length, having two outer corrugated metal skins welded together, sandwiching a core of Class A Urethane, to form a solid composite. The lateral metal skins are linked together within a ISSS Integrated Panel by continuous structural C channels strategically placed and welded to the inner surfaces of the metal skins, for additional structural rigidity and strength. The metal skin sheaths can be finished in almost any material and look, to create a structural element that delivers superior strength, cost performance, insulation, and appearance.
The corrugated metal skins of the ISSS Integrated Panel, both interior and exterior, are built of 26 to 24 gauge steel meeting ASTM/CMHC standards. The standard surface coating is galvanized, over which the necessary finishing may be applied.
The exterior corrugated metal of the ISSS Integrated Panel is continuously roll-formed in the ISS patented manufacturing process. This includes customized uncoiling and corrugating machinery that also places the C-shaped continuous members (which provide additional strength and rigidity) while attaching them to the inner surfaces of the upper and lower skins.
The unique C-shaped continuous metal structure element which provides the structural load bearing capabilities in the ISSS Integrated Panel delivers extraordinary strength and live-load performance characteristics in the ISSS Integrated Panel system.
Each ISSS Integrated Panel is at one end female and at the other end male. The 3.625 inch thick 24 inch wide panels inter-link and secure fasten at 12 inch intervals using TEK screws. Thus, maximum structural support and rigidity, is provided to maintain the structural integrity.
Class A Urethane Foam Core
The ISSS Integrated Panel's insulating core is made of Class A Urethane, a polymerized styrene resin. This is further changed by a fire-retardant additive, and then injected into place between the corrugated metal skins and in the process a sandwich of uniform depth is created and maintained.
The advantages of the Urethane Foam Core in the ISSS Integrated Panel include:
Lower Labor Cost
In a single-step process, the ISSS Integrated Panel permits builders to frame, insulate, sheath, and complete a structure. Cost savings in site assembly and labor are achieved as windows, door frames, plumbing, and electrical are easy to incorporate into the ISSS' Integrated Panel.
Four men and a supervisor can in less than half an hour unload all the building materials for a 1200 plus square foot building. In one day this team can assemble the entire building The assemble speed and procedures, result in lower labor cost and improved materials utilization, less litter, and lower site security requirements.
Integrating Additions
The lSSS Integrated Panel is designed to be utilized for both re-modeling and additions in existing buildings, and for establishing pre-engineered structures from concept to completion.

The major components of the ISSS Panel include the following steel components and urethane foam:
Equipment & Process Elements
The ISSS Panel Manufacturing System production line is 400 feet long and comprises of many specialized pieces of equipment. They handle the top and bottom panel sheath-skins separately, until the skins meet in a pressure foam conveyor, and emerge as an ISSS Panel. Each piece of equipment performs the following functions:
The continuous manufacturing process handles both steel-skins at different times on the assembly line even though they both go through all stages. Thus, the top and bottom skins do not go through the same kind of equipment at the same tires. As an example, as the bottom-skin is fed from a decoiler to the roll-former, the top-skin is fed from a decoiler to straightner. The main stages of the manufacturing stream is described below:
Stage I
The equipment, at Stage I includes - the Decoiler, Top Pallet Uncoiler, First Straightner, First Roll Former.
Top-Skin Process - the rolled steel to form the top-skin is fed into the decoiler which feeds into the first straightner. At the same time, the top-skin pallet uncoiler is releasing a C-shaped continuous member stiffener to the first straighter. The straightner then threads the top-skin (from the decoiler) and aligns and attaches the C-stiffener (from the uncoiler) to the mid-point of the skin. The top-skin with its attached C-stiffener, then enters the first roll-former and is formed into its structural shape.
Bottom-Skin Process - the skin for the bottom is fed from a roil to another decoiler, which feeds the skin to the same first roil-former to follow the top-skin and its C-stiffener through the machine. Now, the bottom-skin, unlike the top-skin, has not yet passed through the uncoiler or straightner to attach its C-stiffener. Thus, the first rollformer does not form or shape the bottom skin.
Stage II
The equipment in Stage II includes - the first roll-former, the bottom-pallet uncoiler, and the second straightner.
Top Skin Process, the top sheath-skin, having already been shaped in the first roll-former, is introduced into the second straightner which attaches the C-shaped continuous member rigidity stiffener to the bottom skin.
Bottom Skin Process: the bottom skin is fed into the first roll-former and into the second straightner, while at the same time the bottom-skin pallet uncoiler is processing the bottom skin C-stiffener to the same equipment - the second straightner. The straightner then threads the bottom-skin (from the roil-former) and aligns and fixes its C-stiffener (from the uncoiler) to the center-point of the bottom-skin
Stage III
The equipment in Stage III includes - the second roll-former, and the urethane foam pressure-conveyor.
Exiting the second-straightner, the sheath forming the top and bottom steel-skins are fed into the seemed roll-former and then to the pressure-conveyor. In the second roll-former, the bottom steel-skin and its C-stiffener are formed into the structure, while the top-skin was previously configured via the first roil-former.
While the top and bottom steel-skins move through the second roll-former, both sheaths are further shaped and formed in preparation for integration into the sandwich Just prior to the two skins entering the pressure-conveyor, they are aligned and spaced into the required positions within the second roll-former.
Jointly, the two steel sheath-skins are then introduced into the urethane foam pressure-conveyor containing the foam injector, foam conveyor, and the curing oven. In the pressure-conveyor the panel undergoes the sandwich process. As the two skins enter the conveyor, the foam injector injects the urethane foam between the sheaths. The pressure-conveyor then compresses the integrated panel and passes it to the curing-oven.
Stage IV
The equipment in Stage IV includes - the run-out conveyor, and the clamp and cut-off saw.
Exiting the curing-oven, the sandwich panel is passed through the run-out conveyor to the clamp and cut-off saw. This equipment cuts the panel to its specified length per the customer application- specification. Also, serial numbers are imprinted on the cut panels, to facilitate the assembly sequence for the building in which the numbered panel is to be applied.
The main computer which controls all aspects of the fully automated and robotized production line also contains all the customer specifications for the sandwich panels including customized-shape, precise length, and numerical panel designation The ISSS Panel thus produced combines the superior structural integrity of the ISS System with the quality output of a certified, automated and robotized production line.
