Part 1: Description
The shop-fabricated 3-D panels consist of a three dimensional welded wire space frame utilizing a truss concept for stress transfer and stiffness. Each surface of the wire space frame has a 2 inch square welded mesh pattern of longitudinal and transverse wires of the same diameter (gauge 11, 12.5 or 14).
Individually welded internal strut wires or diagonals extend through the panel core between each surface. These galvanized strut wires are welded continuously in the required spacing so they form, with the welded wire fabric, into a triangulated truss system which greatly increases the panel strength.
When welded in place, these strut wires pierce through a modified expanded polystyrene core placed between the two layers of welded wire fabric, maintain the required distance apart and provide the shear transfer between the panel surfaces.
The modified expanded polystyrene core (minimum density 0.9 pounds per cubic foot) is held 1/2" or 3/4" from each face of the wire frame to permit the wire to be embedded in an application of approximately 1"-2" thick concrete mixture with 2,500 psi minimum.
Part 2: Scope
2.1: The Contractor Shall:
- Furnish all labor, materials, equipment, supervision and services necessary for the installation of the Tridipanel System in accordance with these specifications and applicable drawings. The 3-D panels shall be manufactured only by Tridipanel System, and marketed only by Tridipanel System or their authorized representatives.
- Fully coordinate the 3-D panel building system with other structural, mechanical, electrical and architectural components of the building structure.
3-D panel wall system caring a complete roof load and also floor joist, prior to having shotcrete applied. I have been showing this photo to many of our engineering firms whom over engineer our product. The nine gauge wires welded from mesh to mesh twelve studs per 3-d panel are stronger than wood studs.

Part 3: Typical Specification
All panel and mesh fabrication shall be in strict accordance with the Tridipanel System Manufacturing Practice and Quality Assurance Proceedures. Structural and fire characteristics shall meet the requirements of the Southern Building Code Congress International, Inc. (SBCCI), the Standard Building Code (SBC), the Council of American Building Code Officials (CABO), the International Conference of Building Officials (ICBO), Building Officials and Code Administrators International, Inc. (BOCA) and Uniform Building and Mechanical Codes (UBC).
Installing Electrical Components
- All design shall be in accordance with that specified in the Tridipanel System literature. Concrete design shall be in accordance with ACI 318-71 or ACI 506R-85 and ACI 506.2-77 (Revised 1983). Steel design shall be in accordance with the American Institute of Steel Construction Specification for Design Fabrication and Erection of Structural Steel. Calculations for loads and loading conditions shall be based on Chapter 12 of the Standard Building Code. The calculations shall confirmthat the panel loads do not exceed those allowed by Section IV of the Southern Building Code Congress International, Inc. Report No. 9019.
- Modified expanded polystyrene should be designed in accordance with American Society of Testing and Materials C578-87a (formerly HH-I-524C).
- All materials used in fabrication and methods of fabrication shall comply with the requirements of the Tridipanel System Manufacturing Practice and Quality Assurance Proceedure.
- All field erection, including panel splice fabrication, shall comply with the Instructions for installing 3-D Panel System.
The manufacture's published installation instructions plus the plans and specifications shall be strictly adhered to and a copy of these instructions shall be available at all times on the job site installation.
3-D construction panels can be stored out of doors on well drained flat surfaces without protective covering. However, due to their light weight, care must be taken to prevent damage from winds. Care must be taken not to store any objects on top of the panels that would break the welds, puncture the polystyrene or warp the panels. Improper storage could result in subsequent alignment problems.

Part 4: Products
The Tridipanel System consists of a three-dimensional welded wire frame, integrated with a modified expanded polystyrene insulation core. Each panel consists of the following:
- Type 1 expanded poltstyrene foam core with a minimum density of 0.9 pounds per cubic foot; a flame spread index of 25 or less and a smoke developed rating of 450 or less when tested in accordance with ASTM E84; a potential heat of 6,000 BTU/sq. ft. or less when tested in accordance with NfiPA259. Thickness of panels can vary.
- The reinforcement module (RIM) is manufactured with highly automated equipment. The welded wire fabric conforms to ASTM A185. The diagonal cross wires, as well as wire used in the fabrication of the welded wire fabric, conform to ASTM A82. Different configurations of RIM are manufactured depending on the end use.
