英国采购需求：隔断/壁板

I'm currently looking for high-quality cement boards in various thicknesses. Specifically, I'm interested in options that are 6mm thick, as well as those available in both 18mm and 22mm. Could you please provide detailed information on your products? I'm eager to know about the specifications, pricing, and any bulk order discounts you might offer. Your prompt response would be greatly appreciated as I'm looking to finalize my supplier soon. Thank you!
