This study assessed the Force-At-Yield properties of three commercially available and ubiquitous samples of medium-density fibreboard (MDF) brands in Nigerian commercial sector to provide technical guidance for material selection in support of sustainable economic development to forestall the prevailing gratuitous financial loss arising from failures resulting from the use of inappropriate Medium-Density FibreBoard (MDF) brands. Four replica tests for Force-At-Yield per brand took place according to testometric testing machine requirement while conforming to ASTM D1037 standard and the average of aggregate also presented. Chats on the characteristics of the Force-At-Yield of the brands resulted through computer program using the generated data. One-Way ANOVA on the results revealed significant differences in force-at-yield among the three MDF brands (F(2, 9) =3,518,673.77, p < 0.001). Tukey’s HSD test at (p < 0.001) revealed a significant difference for each pairwise comparison. SGK Nordic exhibited the highest mean force-at-yield (296.58N), followed by Richard Russel (291.73N) and then MDF Hokusan with the mean value (27.53N). The coefficients of variation ranged from 0.051% to 0.620%, indicating excellent measurement precision. Cohen’s d values ranged from 30.18 to 1643.78, demonstrating extremely large differences between the MDF brands. These findings indicate that the force-at-yield performance of commercial MDF brands in Nigerian economy varies substantially, SGK Nordic exhibiting highest resistance to yielding under the test conditions. Biomedical, Mechanical, Civil, Materials, Production, Metallurgical, Mechatronics, Chemical engineers and construction companies as baseline should value this innovative technical knowledge for sustainable applications in developments of their designs especially in medically non-invasive supportive devices and in construction applications. Force-at-Yield characteristics of other engineered wood products types that have not been investigated warrant further research to provide a more comprehensive understanding of their performance characteristics.
