Solid Source Trading, also known as Solid Source, was established in the year 2013 as sole proprietorship, founded by Engr. Antonio Manas Jr. For over 20 years, Engr. Manas has gained great experience in the construction industry and was able to develop urban-friendly, premium quality-serviced communities and mid-rise projects for several developers.  Through this journey, he saw the need and growth opportunity for gabion baskets in the Philippines. This gave birth to Solid Source Trading and the brand Solid Gabion was created.

Solid Source Trading continued to expand and became a familiar name in supplying high quality gabion cages to the growing construction industry. Aside from the head office in Metro Manila, Solid Source Trading has expanded to Isabela, Pangasinan, and Davao.

With the growing sales, market potential and the expansion plan of Solid Source, Solid Source Trading Corporation was incorporated in the year 2018. This gave way to the growth of the product line.
