Construction Details Materials Materials High quality products begin with high quality materials.   The beauty of natural wood is evident in our products. We use the finest grade western red cedar as our principle construction wood. According to the U.S. Forest Products Laboratory, western red cedar has the lowest rate of shrinkage of any wood, which means it is extremely stable and will be naturally resistant to warping and checking. Western red cedar is also among the most resistant to decay of all domestic woods, so it is the ideal choice for outdoor garden structures. For the lattice wood, we use Cambara mahogany because of its strength in smaller cross sections. It is also very stable and resistant to decay. The lattice is assembled in a variety of ways: woven, full 12 lap, partial 12 lap and the standard overlay method. The lattices are all very strong and assembled with stainless steel to avoid any streaking, rusting or staining of the wood.     Our arbors and trellises are screwed together with stainless steel screws, which are stronger than nails, and won’t rust or stain the wood. Our metal stakes, which secure the arbors in the ground, are 1 3/8” rust proof aluminum pipes, with a thick 1/8” wall and are 48” in length. We use an extremely durable, 100% waterproof polyurethane glue, called Gorilla Glue. It is solvent free and the strongest glue available. Our gate latch is imported from England. It is a very high quality piece of hardware that is galvanized and then black powder coated.
