Product Description

Discover the unparalleled advantages of our Sintered Porous Bricks, meticulously crafted from premium coal gangue shale and boasting a porosity of 28% or higher. Engineered for excellence, these bricks feature numerous small pores, making them the perfect choice for load-bearing walls. Our production process adheres rigorously to the GB13544-2011 standard, ensuring you receive bricks that excel in high alkalinity resistance, seismic durability, superior strength, wear and compression resistance, lightweight properties, and exceptional insulation. Our innovative high-hole design not only boosts efficiency but also slashes energy usage by an impressive 45%. This translates to a larger usable building area, accelerated construction speeds, and reduced mortar consumption. Remarkably, for exterior walls, our sintered porous bricks eliminate the need for additional *** prevention or reinforcement measures. Simply plaster directly onto the surface to cut project costs while maintaining a smooth, ***-free finish over time. Embrace the future of architectural wall materials with sintered porous bricks, the most ideal choice for contemporary construction needs.
