For the installation

Overview

Ipe 4×4 posts deliver serious strength for outdoor builds. First, the true size is 3.5″ x 3.5″, which makes them a solid choice for vertical support. As a result, builders use them for decks, pergolas, and fencing, effectively utilizing IPE 4×4 in various constructions.

Ipe is a very dense hardwood with natural oils. Because of that, it resists moisture, termites, and decay. In addition, it holds up well in harsh sun and wet weather, even with heavy use. When considering materials, the toughness of posts like Ipe 4×4 is unmatched.

Each post comes kiln-dried for better stability. It is also FSC-certified, so it supports responsible sourcing. Moreover, the S4S E4E milling creates smooth faces and clean edges. Therefore, the post looks sharp and installs with a uniform finish, reflecting the quality associated with such posts as IPE 4×4.

For added peace of mind, Ipe carries a Class A fire rating. So you get strong fire performance without chemical treatments. This safety feature is another reason to choose an outdoor layout featuring IPE 4×4.

IPE DECKING LOS ANGELES REVIEW

I started buying IPE from Brazilian Lumber over one year ago before the vendor opened the California location (i.e. where I am located). There were some issues related to the lumber (IPE), BUT the vendor made sure that all was taken care of and that I was happy. I mentioned “the issues” not to say that they product is bad, but rather to stressed out that the vendor provides superb service. No matter what you do, the problems may happen. Important is how such situations are handled. I was working with Luis, great guy to work with. I recommend this vendor.

I upgraded my backyard with Ipe deck tiles for my patio. It was definitely an investment, but it’s turned out to be worth every penny. The tiles were easy to install and the finished product is not only beautiful, but also incredibly durable and functional. I would highly recommend Ipe deck tiles to anyone looking to create a beautiful and long-lasting outdoor space.

The best place to get Brazilian hardwood that I\’ve found anywhere in California or online. The customer service is very good, the reps are attentive to you upon arrival and they are very knowledgeable. The quality of wood is superb and the pricing is cheaper than I can find anywhere else.
