Manbarklak is an imported hardwood
Manbarklak is a common name applied to species in the genus Eschweilera. Other names include kakaralli machinmango, and mata-mata. About 80 species of this genus are distributed from eastern Brazil through the Amazon basin, to the Guianas, Trinidad, and Costa Rica.
The heartwood of most species is light, grayish, reddish brown, or brownish buff. The texture is fine and uniform, and the grain is typically straight. Manbarklak is a very hard and heavy wood (density of air-dried wood ranges from 768 to 1,185 kg/m3 (48 to 74 lb/ft3)) that is rated as fairly difficult to dry. Most species are difficult to work because of the high density and high silica content. Most species are highly resistant to attack by decay fungi. Also, most species have gained wide recognition for their high degree of resistance to marine borer attack. Resistance to dry-wood termite attack is variable depending on species.
Manbarklak is an ideal wood for marine and other heavy construction uses. It is also used for industrial flooring, mill equipment, railroad crossties, piles, and turnery.
