Panel-Lam Plant Fabrication

1 --- Individual laminates are planed in the Timber Sizer to provide uniform thickness, then Precisions Double End Trimmed to exact length.

2 --- The Gang Drill places dowel holes in a pattern determined by design calculations and assumptions.

3 --- West Coast Douglas Fir must be incised before treatment to ensure proper penetration of preservative.

4 --- Once all framing, drilling and other fabrication is complete, all bridge components are pressure treated with Copper Naphthenate prior to assembly.

5 --- Wheeler's treating facility is state-of-the-art, providing enhanced quality control.

6 --- All treated materials are certified through an independent third party inspection service, Timber Products Inspection Company (TPI).

7 --- Panels are assembled by first starting the dowels in the pre-drilled holes of the laminates.

8 --- Laminates are placed into the press in pairs. The press then pushes all the dowels simultaneously until they penetrate four members.

9 --- Splice blocks are added and the panels are banded for shipping.

10 --- All panels are clearly marked according to final location per the project plans.

11 --- Spreader beams, curb, rail, posts, and miscellaneous components are match-marked and bundled for shipping.

12 --- Materials are loaded on independent carriers for shipment to the project site.
