In this video you can see our 200ft Prestress tables in action. First, the tables are fit with the proper forms for the specifications needed. Second, the forms are tack welded to secure them in place. Third, No. 4 rebar is pulled through the entire table lengthwise and 3/8" strands are placed perpendicular to the No. 4 rebar, this creates a grid pattern to reinforce the concrete panels. Then, hooks are weaved into the grids. Now it is time for concrete! Concrete is poured and leveled into the forms, then the concrete is covered with a tarp. Then the concrete sits overnight or until the concrete is dry.
Phases of prestress production process are:
1) preparing the form
2) placing of reinforcement rebar (No.4)
3) prestressing
4) casting/pouring of concrete
5) removing the form liners
6) storage
