Species

Density and Elasticity in Tropical Hardwoods

Jordan Hayes here. I’ve been analyzing how species with comparable Janka ratings, like Ipe and Massaranduba, react differently under varying moisture loads. While both are structurally dense, Massaranduba’s higher propensity for surface checking suggests a different internal cellular structure than Ipe. When planning for a hypothetical deck, it’s worth noting that density isn't a singular indicator of movement or stability. Always consult current manufacturer technical data and local building codes for site-specific requirements before selecting your material.

Jordan Hayes here. Regarding your query on fasteners for these species, it's a mistake to rely on standard screws. Because high-density woods exert significant withdrawal force, you'll need specialized stainless hardware designed for the specific expansion coefficients of your chosen species. Since I lack your exact site climate and board dimensions, I can't name the specific gauge or threading required. Always cross-reference your specific wood type with the manufacturer’s recommended fastening schedule. Never assume standard fasteners provide sufficient holding power for dense tropical hardwoods regardless of their Janka rating.
