About us progroup


TS STEEL ENTERPRISE CO., LTD, and it’s affiliated companies started establishing in the 1970s. We started up from manufacturing motorcycle parts, gratings, as well as refrigerator shelving trays. Not long after, we had the opportunity to supply the shelving trays to Thailand’s top leading domestic refrigerator company. Consequently, this business has expanded to manufacturing and supplying shelves, racks, displays, and furniture to many different establishments. We currently supply shelvings to convenience stores, supermarts, outlets, bookstores, mall shops, warehouses, and more. Progroup has a team of professionals ready to serve you. We attend to every process; from the initial discussion, consultation, design, production process, delivery and installation, even up to the after-sales service. In the last 3 consecutive years, we garnered a sales volume of more than 300 Million baht/year.
