Industrial Mineral Supply to Istanbul: Turkey's Largest Market
With a population exceeding sixteen million, massive construction projects, a deep-rooted industrial infrastructure, and continuously growing infrastructure investments, Istanbul is the city with the most intensive industrial mineral consumption in Turkey. From quartz sand, silica sand, and filter sand to epoxy aggregate, from foundry sand to artificial turf field sand, simultaneous demand comes from all 39 districts of Istanbul for almost every product group. The amount of building materials consumed in a single day exceeds the annual consumption of many provinces. Say Quartz serves this giant market, just a few hours away from its production facilities in Tekirdağ Çorlu, with a daily production capacity of 5,000 tons.
European Side Industrial Corridor: Foundry and Sandblasting
Industrial zones extending along the Beylikdüzü, Esenyurt, and Büyükçekmece line on Istanbul's European side are areas where metal processing and foundry sectors are concentrated. In these facilities, silica sand is consumed as the primary raw material in molding and core-making. Say Quartz's silica sands in 7 different granulometries — from fine-grained precision casting to coarse-grained heavy metal casting — respond to the diverse needs of manufacturers in this region. The fire resistance and thermal stability of silica sand are the parameters that directly determine casting quality.
Sandblasting and surface preparation operations are performed intensively at industrial facilities in Avcılar and Küçükçekmece. Silica sand is regularly ordered for surface preparation operations across a wide range from steel construction workshops to automotive sub-industry establishments. Silivri, as a district where logistics centers and large-scale production facilities are located, also generates demand for both foundry and sandblasting sand. Sandblasting sand is also used in the maintenance of metal equipment at agricultural and livestock facilities in Çatalca.
Mega Projects and Construction Chemicals
Istanbul's continuously ongoing urban renewal process creates enormous demand for quartz sand-based construction chemicals. Urban renewal projects in Bağcılar, Esenler, Gaziosmanpaşa, and Sultangazi; new residential areas in Başakşehir, Arnavutköy, and Sancaktepe; renovation works in Bahçelievler, Bakırköy, and Güngören — in all these projects, quartz sand is used in grout fillers, facade moldings, exterior cladding, and plaster additives. The performance of construction chemicals — water resistance, bonding strength, elasticity — is directly related to the grain size and purity of the quartz sand used.
Say Quartz's quartz sands in 12 different grain sizes, ranging from 100 microns to 32 millimeters, adapt to every type of formulation needed by building materials manufacturers. Building materials production facilities in Bayrampaşa and Kağıthane are among the important buyers of these products. Building materials wholesalers in Zeytinburnu are important distribution points that serve construction projects across Istanbul.
Growth and Construction on the Asian Side
The Pendik, Kartal, and Tuzla line forms the industrial and commercial axis on Istanbul's Asian side. While shipyards and ship maintenance facilities in Tuzla consume sandblasting sand, construction projects in Pendik and Kartal continuously generate demand for quartz sand-based construction chemicals. Ataşehir's rapid development toward becoming a financial center and Ümraniye's commercial space projects are important consumption points for epoxy aggregate used in epoxy floor coating applications. Epoxy floors preferred in premium commercial spaces offer high performance in both aesthetics and durability.
Çekmeköy, Sultanbeyli, and Sancaktepe are extremely active in terms of residential construction as Istanbul's rapidly growing eastern districts. In new residential areas in these regions, demand for quartz sand for construction chemicals is growing year by year. Maltepe contains both demand groups with both residential and commercial real estate projects. In historic fabric renovation projects in Üsküdar and Kadıköy, sensitive applications requiring special construction chemicals are involved.
Drinking Water Treatment Infrastructure
The drinking water needs of Istanbul's enormous population are met by large-scale treatment facilities. In these facilities, Say Quartz's filter sands produced in 11 different types play a critical role in safely transferring water to the network. Filter sands in different sizes from 0.4 millimeters to 32 millimeters are present at every step of multi-stage treatment processes. Regular maintenance and material renewal of filter beds is essential for maintaining water quality standards.
Water collection basins in districts such as Beykoz and Sarıyer surrounded by forested areas feed Istanbul's natural water resources. Including the rural water networks in Şile, filter sands, hydroanthracite, activated carbon, and garnet filter products are regularly supplied across Istanbul. In addition to large-capacity treatment facilities, water treatment units within residential complexes, hotels, and industrial facilities are also filter sand consumption points.
Rail Systems and Traction Sand
Istanbul's continuously expanding metro, tram, and suburban train network makes it the city with the most intensive traction sand consumption. Traction sand applied to rails in rainy weather and on inclined routes is a fundamental material that improves braking safety. Tram and metro lines passing through Fatih, Beyoğlu, Şişli, and Üsküdar, rail system routes connected to Eyüpsultan and Kadıköy — all require regular traction sand use. Including the Marmaray line, Istanbul's rail transportation network consumes high quantities of traction sand annually.
Sports Facilities and Recreation Areas
Each of Istanbul's 39 districts has numerous artificial turf facilities. Hundreds of artificial turf fields in high-population districts such as Bağcılar, Esenyurt, Pendik, and Ümraniye are filled with specially granulated artificial turf field sand. The round grain structure of artificial turf field sand is the primary factor that determines fill performance among synthetic grass and player comfort. Playground sand used in children's playgrounds is produced conforming to hygiene and safety standards; from Adalar to Arnavutköy, there is demand for this product in every park in Istanbul.
Epoxy aggregate is a coating raw material preferred in Istanbul's luxury residential projects, hotel floors, shopping center common areas, and industrial facility floors. Epoxy floor applications are becoming more widespread in premium commercial areas in Beşiktaş, Şişli, Kadıköy, and Bakırköy. Decorative epoxy coating applications are also seen on restaurant and cafe floors in Beyoğlu.
