ABOUT US
More Than 20 Years of
Glass & Aluminum
ESJ Glass and Aluminum Supply began in Tanjay City, Negros Oriental, with two people and a small line of glass and aluminum products. Today we supply, fabricate and install for homes, businesses and public buildings across the province and beyond.
OUR STORY
From a Tanjay Shop to
Four Offices
ESJ Glass and Aluminum Supply was founded in Tanjay City as a sole proprietorship with 100% Filipino capital, two personnel and an initial line of glass and aluminum products.
Over more than two decades it has grown into a trusted provider for residential and commercial buildings, government infrastructure and industrial facilities. To reach more customers we opened branches in Dumaguete City, Kabankalan City and, most recently, Sibulan.
On February 23, 2019 the business was incorporated as Salfra Pentagon Corporation — a private, family-owned, 100% Filipino company that continues to trade as ESJ Glass and Aluminum Supply.
