Vietnam's accelerating industrialization drives significant local demand for premium-grade silica bricks across multiple sectors
Hanoi's growing steel industry, anchored by major facilities in Hung Yen and Bac Ninh, relies on high-density silica bricks for coke ovens and electric arc furnaces. SK silica bricks withstand temperatures exceeding 1650°C with minimal deformation.
Vietnam's booming construction sector — fuelled by major infrastructure projects in and around Hanoi — demands consistent cement output. SK silica bricks provide superior thermal stability for rotary kilns and vertical shaft kilns used in cement and lime production.
With Vietnam's flat glass and container glass industries expanding to meet domestic and export demand, silica bricks are critical for regenerator chambers and glass-melting furnace crowns — applications where SK's products excel in longevity and consistent performance.
Industrial zones such as Nam Thang Long and Sai Dong in Hanoi host petrochemical and specialty chemical facilities that require high-purity silica brick linings for reactors, reformers, and cracking units operating under extreme thermal cycling conditions.
Vietnam's traditional and industrial ceramics manufacturers — particularly around Bat Trang, a historic ceramic village just 10 km from Hanoi — increasingly upgrade their kilns with advanced silica brick linings for improved energy efficiency and product quality.
Thermal power plants and combined heat-and-power (CHP) units supplying Hanoi's expanding energy grid require robust refractory lining solutions. SK silica bricks offer excellent resistance to thermal shock and chemical erosion in boiler and combustion chamber applications.
SK Refractories' quality is embedded in every aspect of operations, from raw material sourcing to production and delivery. We partner with trusted suppliers to secure premium-grade raw materials, leveraging advanced manufacturing processes — such as automated pressing and controlled sintering — to ensure consistency and reliability.
Our quality management system is certified to ISO 9001, reflecting our dedication to maintaining the highest standards of excellence. SK Refractories' main refractory products for industrial furnaces include zircon bricks, corundum bricks, mullite bricks, sillimanite bricks, silica bricks, magnesia bricks, low porosity fireclay blocks, insulation bricks, and more.
SK Refractories has an annual production capacity of 20,000+ tons. With scientific management, advanced technology and equipment, and a strict quality control process, SK Refractories ensures the highest quality of refractory bricks for industrial furnaces.

Vietnam's GDP growth of 6–7% per year continues to accelerate heavy industrial output. The Ministry of Industry and Trade projects Vietnam's steel production to exceed 30 million tons annually by 2030, directly increasing demand for premium refractory silica bricks across Hanoi and northern industrial provinces.
Vietnamese regulations increasingly target carbon reduction and energy savings. High-performance silica bricks with low thermal conductivity reduce furnace heat loss, cutting fuel consumption by up to 15%. This aligns with Vietnam's National Green Growth Strategy and makes SK bricks a future-ready investment.
Modern refractory silica bricks now feature SiO₂ content exceeding 96%, enhanced with micro-silica additions for improved density and resistance to alkali attack. SK Refractories continuously invests in R&D to deliver next-generation silica brick formulations suitable for Vietnam's harshest operating environments.
The China–Vietnam trade corridor has matured significantly, with reliable sea freight from Tianjin or Shanghai to Haiphong Port — just 120 km from Hanoi — enabling 7–12 day lead times. This makes sourcing from SK Refractories in Zhengzhou both cost-effective and logistically efficient for Hanoi-based projects.
Foreign direct investment into Hanoi's industrial parks — from Samsung, LG, Canon, Foxconn, and dozens of European manufacturers — creates a sustained pipeline of new factory builds and furnace installations. SK Refractories' ability to supply large-volume, custom-specification silica bricks positions it perfectly for these mega-projects.
Vietnam's refractory market is maturing beyond simple product purchasing toward full technical partnership. SK Refractories provides furnace lining design consultation, installation guidance, and performance tracking — giving Hanoi clients a competitive edge in furnace lifespan and operational efficiency.
SK Refractories is well known in domestic markets and abroad for the quality of its refractory bricks. The refractory materials produced by SK Refractories have been exported to more than 35 countries including America, Spain, Germany, Italy, Brazil, Belgium, India, Japan, Korea, and now increasingly to Vietnam and Southeast Asia.
The main products include Silica Brick, low porosity fireclay blocks, Sillimanite Brick, Corundum Brick, Zircon Brick, Mullite Brick, Insulating Bricks, refractory castables, and refractory mortar of related materials.
Every batch of silica bricks destined for Hanoi customers undergoes rigorous multi-stage inspection: raw material analysis, green body testing, post-firing dimensional checks, and third-party laboratory certification upon request — ensuring your furnace lining performs at the highest possible level.
