Environmentally friendly reusable structure for use in construction

An extruded structural profile for casting concrete, comprising:

• a length, a width, and a thickness;
• a first side and a second side opposite the first side, the first and second sides defining the width and the length;
• a first edge and a second edge opposite the first edge, each of the first and second edges extending between the first and second sides and defining the thickness;
• a plurality of support beams, each support beam extending between the first side and the second side;
• a fastener disposed at a first end of each of the plurality of support beams, the fastener adapted to help secure an interfacial layer to the extruded structural profile;
• and
• a groove disposed along the first edge and a tongue disposed along the second edge, the tongue configured to be disposed in a groove of a second extruded structural profile to join the extruded structural profile and the second extruded structural profile together, and the groove configured to receive a tongue of a third extruded structural profile to join the extruded structural profile and the third extruded structural profile together;
• wherein each of the fasteners is a female fastener that is formed in either the first side or the second side and includes a recess into a corresponding support beam of the plurality of support beams.

A method for making a reusable modular structural member for casting concrete, the method comprising:

• forming first and second structural profiles, each structural profile formed of metal and having:
• a length, a width, and a thickness;
• a first side and a second side opposite the first side, the first and second sides defining the width and the length;
• a first edge and a second edge opposite the first edge, each of the first and second edges extending between the first and second sides and defining the thickness;
• a plurality of support beams, each support beam extending between the first side and the second side;
• a fastener disposed at a first end of each of the plurality of support beams;
• and
• a groove disposed along the first edge and a tongue disposed along the second edge of the reusable structural member;
• connecting the first and second structural profiles by disposing the tongue of the first structural profile in the groove of the second structural profile, thereby forming a connected structure;
• and
• applying an interfacial layer on the connected structure,
• wherein at least one of the support beams and the interfacial layer comprises recycled material.
