ZTWY SANDWICH PANEL: A Trusted Manufacturer of High-Performance Metal Envelope Solutions for Modern Steel Structures

ZTWY SANDWICH PANEL has established itself as a reliable manufacturer of premium metal envelope materials that seamlessly integrate with steel structure systems. Specializing in insulated wall and roof panels, ZTWY ensures exceptional energy efficiency, fire resistance, and long-term durability even under extreme environmental conditions.



Among ZTWY’s key product lines are PUR (Polyurethane) insulated wall panels. These panels deliver superior thermal insulation, high fire resistance (Class B-s1), and outstanding dimensional stability. The closed-cell PUR core is highly resistant to moisture, making it suitable for both cold storage facilities and general building envelopes.

Additionally, ZTWY offers Rock Wool Sandwich Panels, renowned for their excellent fireproof rating, sound insulation properties, and sustainable profile. These panels are particularly ideal for projects with stringent fire safety requirements, such as industrial plants, power stations, and public buildings.



All ZTWY panels feature high-quality metal surfaces—typically color-coated galvanized steel or aluminum-magnesium-manganese alloy—providing robust weather resistance, aesthetic versatility, and corrosion protection. Customization in color, texture, and profile is available to meet diverse architectural demands.



With over two decades of industry expertise, ZTWY SANDWICH PANEL is recognized for its innovation, large-scale production capabilities, and successful execution of international projects. From standard industrial applications to high-end architectural facades, ZTWY continues to deliver tailored solutions that enhance modern steel structure construction.

In summary, as the construction industry increasingly embraces integrated, energy-efficient, and modular building systems, ZTWY’s metal envelope products—including PUR and Rock Wool insulated panels—provide both functional performance and design flexibility. These solutions help developers and contractors achieve sustainable, long-term value in their projects.
