In June 2023, we shipped 100mm×1000mm Z-type joint rock wool wall panels to Brazil, with a total quantity of 4 containers (approximately 2,400 square meters). The product features 100kg/m³ rock wool core density and 0.5mm-thick white-gray color steel sheets on both sides. Designed for indoor partition walls and external wall cladding, these panels offer excellent fire resistance, thermal insulation, and heat preservation performance. Our products have received high praise from the customer, and a long-term cooperation contract has been established.
