Our pergolas are constructed from Western Red Cedar. We customize with a variation of end cuts from the classic pergola to the modern cut. The homeowner has the choice of using all-thread bolts to attach beams or OZCO post to beam brackets for durablity in earthquakes. Where conventional lag bolts could loosen over time, all thread bolts will eliminate that possibility. All posts are attached to concrete with OZCo mounting brackets. No posts are buried in the ground to preserve the wood. Corners are braced with angle braces for added strength. We also offer rain and hail protection with Lexan poly carbonite sheeting, that comes in multiple colors.
