Highland Refractory categorizes Acid Resistant Bricks based on raw material composition and acid resistance levels to adapt to diverse industrial corrosive environments, including Clay Acid Resistant Bricks (made from high-purity clay, suitable for weak to moderate acidic scenarios like chemical plant floor linings) and Siliceous Acid Resistant Bricks (with high silica content, ideal for strong acidic environments such as sulfuric acid storage tank linings); each type of Acid Resistant Brick is engineered to meet specific acid concentration and temperature requirements, ensuring reliable performance in targeted corrosive settings.
Highland’s Acid Resistant Brick stands out in corrosive industrial conditions with core strengths: it exhibits excellent resistance to a wide range of acids (including sulfuric, hydrochloric, and nitric acid), maintaining structural integrity even after long-term exposure; it has good wear resistance, preventing surface damage from mechanical friction in high-traffic areas like chemical plant walkways; it also features stable thermal performance, avoiding cracking under temperature fluctuations common in acid processing equipment—these advantages make the Acid Resistant Brick a trusted choice for protecting infrastructure from acid corrosion.
Acid Resistant Bricks are widely used across sectors that handle corrosive media: in the chemical industry, they line reaction vessels, acid storage tanks, and floor surfaces to prevent acid leakage and infrastructure damage; in the metallurgical industry, they protect pickling tanks used for metal surface treatment, resisting the corrosive effects of pickling solutions; in the pharmaceutical industry, they line clean rooms and process equipment where high-purity, acid-resistant surfaces are critical—each application leverages the Acid Resistant Brick’s ability to withstand harsh chemical environments, ensuring safe and stable production.
Acid Resistant Bricks (Highland) excel in corrosive environments, offering superior resistance to various acids (weak to strong) and reliable performance in chemical processing, pickling, and acid storage scenarios; High Alumina Bricks, by contrast, specialize in high-temperature stability, with strong load-bearing capacity at ultra-high temperatures (up to 1700℃) and excellent thermal shock resistance, making them ideal for furnace linings and high-heat structural components in steel, cement, and glass industries—each product targets distinct industrial needs, with the Acid Resistant Brick leading in acid corrosion protection while High Alumina Bricks dominate high-temperature structural applications.
Highland Refractory is a leading producer of high-quality Acid Resistant Bricks, backed by 30+ years of refractory expertise—we use high-purity raw materials (such as refined clay and silica), adopt advanced sintering technologies to enhance acid resistance, and implement strict quality control (testing acid corrosion rate, wear resistance, and thermal stability for every batch), ensuring each Acid Resistant Brick meets global industrial standards; we also hold ISO 9001/CE certifications, maintain an annual production capacity of 60,000 tons, and serve 1,500+ clients across Asia, Africa, Europe, and Australia, making us a reliable partner for Acid Resistant Brick needs.
Choosing Highland Refractory for your Acid Resistant Brick requirements means accessing tailored solutions and comprehensive support: we offer customization (adjusting the Acid Resistant Brick’s thickness, size, and acid resistance level to match your specific corrosive environment, such as strong acid storage vs. weak acid flooring), fast delivery (3–7 days for standard sizes in stock, 10–15 days for custom batches), and bulk discounts (5–10% off orders ≥ 500 pieces); we also provide free samples, detailed quality inspection reports, and 24/7 technical guidance (advising on installation and maintenance for acid-prone areas), ensuring your Acid Resistant Brick investment delivers long-term protection and value.
Zhengzhou Gaoyuan Refractory Co., Ltd., a trusted refractory manufacturer with over 30 years of experience in the refractory industry, offers factory direct sales, fast delivery within 3-7 days, and exclusive bulk purchase discounts to meet the high-temperature demands of the global petrochemical, steel, cement, and glass industries.

A: For standard Acid Resistant Bricks that we have in stock, you can expect to receive them within 3 - 7 days. If you've placed an order for customized Acid Resistant Bricks, which may need extra time for special production processes, it'll take about 10 - 15 days. For large - scale bulk orders, we'll work with you to determine a suitable delivery schedule based on your project's timeline.
A: Each Acid Resistant Brick is carefully wrapped in a layer of moisture - proof material to protect it from humidity during transit. Then, to prevent breakage, we place them in sturdy wooden crates. Inside the crates, the bricks are separated by shock - absorbent foam. The crates are reinforced with steel straps at the corners and clearly labeled with "Fragile" and handling instructions in multiple languages to ensure safe delivery.
A: Yes, we offer free samples of our standard Acid Resistant Bricks. You just need to cover the shipping cost to your address. If you're interested in custom - made samples, a small fee may apply, but this fee will be fully refunded when you place a large order with us.
A: We accept T/T (Telegraphic Transfer) and PayPal for payments. Similar to our other refractory products, we require full payment before we dispatch the Acid Resistant Bricks. However, we're always exploring more payment options to make it more convenient for our customers.
A: Absolutely. Every batch of Acid Resistant Bricks produced by Highland Refractory undergoes strict quality control. You'll receive a detailed quality inspection report that includes information about the raw materials used, the manufacturing process, and the results of various tests for acid resistance, wear resistance, and other important properties.
A: We take great care in packaging our Acid Resistant Bricks to minimize the risk of damage during shipping. But in the unlikely event that you receive any damaged bricks, please contact us immediately. We'll arrange for a replacement of the damaged items as soon as possible at no extra cost to you.
