Company Information

Page 1

We are a joint corporation between Makitech Co., Ltd. and Heartful International Co., Ltd. Makitech is a conglomerate which comprises of conveyor, solar system, LED, grating and nursing care business. Heartful engages in grating production, welding and have an overseas global import-export business network. Our steel grating and galvanization production facilities are all new and management is run by Japanese to ensure high quality control. Our products are used for construction, road, plant, shipyard, incinerators as well as end-users. Steel gratings are highly consumed in infrastructure works in Vietnam and Asian countries. We export steel grating to Japan, Oceania, North America and Middle East countries.
