Acid Resistant Bricks vs. Tiles
REBO acid resistant bricks and tiles both stop chemical damage because of their strong ceramic materials. However, bricks are very thick and heavy to support big industrial machines and extreme heat inside chemical storage tanks. Acid resistant tiles are much thinner and lighter, so people use them to protect laboratory floors, kitchen walls, and walkways from everyday acid spills.
| Feature | Acid Resistant Bricks | Acid Resistant Tiles |
|---|---|---|
| Main Series & Sizes | 230×113 Series | 150×75, 150×150, 200×200, 300×300, 600×300, 600×600 Series (mm) |
| Thickness Range | 15–65mm (Heavy-duty thick options) | 15/20/30mm (Standard thickness) |
| Primary Applications | Heavy industrial equipment interiors: Acid tanks, pickling pits, reaction vessels, tower linings, chimneys. | Large area flooring: Chemical factory workshops, galvanizing shop floors, battery rooms, warehouses. |
| Load & Impact Resistance | Ultra-high compressive strength | High load-bearing |
| Installation & Joints | Often requires staggered laying and skilled masonry for curved or complex vessel structures. | Laid flat on large surfaces, prioritizing anti-slip textures, aesthetic neatness, and easy cleaning. |
