美国采购需求：耐酸砖、耐火砖

I'm looking to procure basic refractory bricks with specific dimensions of 250mm in length, 125mm in width, and 65mm in thickness. Could you please provide details on the available options, including any variations in material composition or performance characteristics? Additionally, I'd like to know about pricing, minimum order quantities, lead times for delivery, and any certifications you might have. Your prompt response would be greatly appreciated, as I'm eager to move forward with this sourcing process. Thank you!
