Tests & Approvals

GCT Structural Insulated Building Components are prefabricated lightweight structural sections for all building needs. The sections consist of an EPS core that is sandwiched between two layers of galvanized high strength wire mesh.
A galvanized wire connector wire is pierced through the EPS core and welded to each of the outer galvanized mesh layers. This meshwork is made from steel having a minimum yield of 87,000 psi and a minimum fracture of 99,000 psi. This configuration complies with ACI, section and IBC, section 1903.
GCT Structural Insulated Building Components are covered in the field, with a high strength mortar compliant to ASTM C-387 such as GCT Structural Mortar Mix.
GCT Structural Insulated Building Component System is manufactured with M2® Technology and our proprietary design meet the following requirements under the Technical Evaluation Report performed by Structural Building Components Research Institute (SBCRI) and DrJ Engineering, LLC:
