In 2013, Engr. Antonio Manas, Jr. founded Solid Source Trading, operating as Solid Source, as a sole proprietorship. With 20+ years in construction, he successfully developed premium serviced communities and mid-rise projects. Recognizing the demand for gabion baskets in the Philippines, he launched Solid.ph, expanding to Isabela, Pangasinan and Davao alongside the head office in Metro Manila.

Solid.ph, a reputable name in gabion cage supply, expanded its product line to sheet piles, foldable containers, and portalets due to growing sales and market potential. Serving projects nationwide, Solid.ph prioritizes unparalleled customer service, fostering strong business relationships with each client.
