Product Description

Experience the unbeatable benefits of our Sintered Porous Bricks, expertly engineered from high-grade coal gangue shale with an impressive porosity of 28% or more. Designed for superior performance, these bricks are adorned with countless small pores, making them the ultimate solution for load-bearing walls. Our rigorous production process aligns perfectly with the GB13544-2011 standard, guaranteeing bricks that offer outstanding resistance to high alkalinity, superior seismic durability, exceptional strength, unparalleled wear and compression resistance, a lightweight structure, and top-tier insulation. Our state-of-the-art high-hole design not only enhances efficiency but also cuts energy usage by a remarkable 45%. This results in a larger usable building area, faster construction times, and decreased mortar consumption. Astonishingly, when used for exterior walls, our sintered porous bricks negate the need for additional *** prevention or reinforcement. You can plaster directly onto the surface, significantly reducing project costs while ensuring a smooth, ***-free finish that lasts. Step into the future of architectural wall materials with our sintered porous bricks, the perfect choice for modern construction requirements.
