Cumaru

Dipteryx odorata

Porta Cumaru is an extremely strong timber - beams are strength graded to F34 and posts to F27. This stronger timber enables longer spans, reduces number of posts and saves you money for on-site labour. Porta Cumaru has a very high density of 1,085 kg/m3. It meets the requirement as a BAL 19 timber as specified in AS 3959-2009 for use in timber construction in bushfire zones. Porta Cumaru is a Class 1 timber with an above-ground life expectancy of greater than 40 yrs and in-ground of greater than 25 years. Also termite-resistant.

Porta Cumaru is an attractive timber, with a unique interlocking grain. Mid-brown in colour with a reddish or purple hue when cut changing to brown with red or gold flecks. It can age to a lustrous grey if left uncoated.

Pre-drilling for screwing or nailing when installing decking is recommended. Its inherent hardness has a blunting effect on tool cutting edges, therefore saws/chisels/drills etc. need to be sharpened more often. It can be sanded, oiled and painted very easily. Porta recommends using an oil-based paint/stain preparations due to its high timber density, as water-based products have minimal penetration for long-term coating durability. Compared to other hardwoods tested Porta Cumaru demonstrated near-zero tannin bleed. However Porta recommends cleaning of timber prior to installation and a suitable sealer to protect the timber and minimise any potential run off of natural resins onto surrounding surfaces.

Porta Cumaru is ideal for applications where a durable timber is needed such as decking, cladding, pergolas, boardwalks, street furniture and marina applications.
