Choosing the right hardwood decking can be challenging because each species offers different benefits in terms of durability, color, maintenance, and cost. Popular options like Cumaru, Garapa, Ipe, Iroko, and Ash decking are all known for their strength and natural beauty, but they perform differently depending on the environment and how the deck will be used. Some hardwoods are extremely dense and long-lasting, while others provide lighter color tones or a more budget-friendly option. To help simplify the decision process, we created the comparison table below so you can quickly see how these hardwood decking materials compare across the most important factors.
