Abstract. This research investigated the extent of supply chain activities and the challenges of construction hardware enterprises in Bacolod City, focusing on supplier management, procurement, inventory management, logistics, and transportation. Driven by a scarcity of local studies on supply chain activities in small to medium construction hardware enterprises, the study utilized a descriptive-correlational research design. The researcher developed a questionnaire that underwent validity and reliability tests and was distributed to two hundred twelve randomly selected participants. The data collected were examined using mean, standard deviation, Kruskal-Wallis U, Mann-Whitney U, ANOVA, t-test, and Spearman's rho. The findings indicated a high extent of supply chain activities. Conversely, the level of challenges was found to be low. Additionally, the results showed a significant difference in the extent of supply chain activities when grouped by form of organization and capitalization (p < .05). However, no significant difference was noted when grouped by length of operations (p > .05). On the level of challenges, the results demonstrated no significant difference when grouped by form of organization, capitalization, or length of operations (p > .05). Furthermore, the study found no significant relationship between the extent of supply chain activities and the level of challenges (Spearman’s rho, p > .05). The results imply that supply chain activities are effectively implemented and challenges are generally manageable. Based on the study's findings, strategies for enhancing the supply chain processes were proposed, especially for those with limited capital or small companies. These strategies carry practical implications for improving operational efficiency, supplier coordination, and logistical planning in the sector.
