| description | Hornbeam wood (Carpinus betulus) is a native species from Iran and covers 33% of the commercial volume of Iranian woods. Surface quality of solid wood products is one of the most important properties influencing further manufacturing processes such as finishing or strength of adhesive joint. Wood surface roughness is affected by growth condition. The objective of this study was to evaluate effect of altitude index (400 m, 800 m and 1200 m) on the surface roughness of sanded hornbeam wood (C. Betulus). Surface characteristics of sanded specimens of hornbeam wood were made employing a stylus profilmeter. Average roughness (Ra), mean peak-to-valley height (Rz), root-mean square deviation of the profile (Rq), core roughness depth (Rk), reduced peak height (Rpk), and reduced valley depth (Rvk) roughness parameters were used to determine surface characteristics of the test pieces. Significant statistical differences were found among altitude indexes in reduced valley depth parameter and wood oven-dried density, but not for the other variables. This variable did not have significantly effect on other surface roughness parameters in hornbeam wood. The low altitude had a rougher surface than intermediate and high altitudes. There is no relationship between surface roughness parameter and wood oven-dried density. |

La especie Carpinus betulus (‘hornbeam’) es una especie nativa de Irán y cubre 33% del volumen comercial de las maderas de este país. La calidad de la superficie de productos de madera sólida de ‘hornbeam’ es una de sus propiedades más importantes, que afecta los procesos de manufactura tales como acabados o resistencia de las uniones con adhesivos. La rugosidad de la superficie de la madera se ve afectada por las condiciones de crecimiento del árbol. El objetivo de este estudio fue evaluar el efecto del índice de altitud (400 m, 800 m y 1200 m) en la rugosidad de la superficie de madera de ‘hornbeam’ lijada. Las características de la superficie de muestras de madera de ‘hornbeam’ lijadas se midieron con un equipo llamado medidor de perfiles de contacto “Contact stylus profilmeter” PGK. Las características de la superficie de las muestras medidas fueron: rugosidad promedio (Ra), altura promedio cresta a valle (Rz), desviación media de los cuadrados medios de la rugosidad (Rq), profundidad de la rugosidad del núcleo (Rk), altura de la cresta reducida (Rpk) y profundidad del valle reducida (Rvk). Se encontraron diferencias estadísticas significativas entre los índices de altitud para la variable profundidad de valle reducida y para la densidad de la madera secada en estufa, pero no para el resto de las variables. Esta variable no tuvo un efecto significativo en los parámetros de rugosidad de la madera de ‘hornbeam’. La madera de altitudes bajas tuvo una superficie más rugosa que las altitudes intermedia y alta. No hay relación entre la rugosidad y la densidad de la madera secada en estufa.
