Four Waves Roof Sandwich Panel
Thermal insulation: The material has excellent thermal insulation performance.
Lightness: It helps reduce the load on the building structure and lower construction costs.
Durability: It has high compressive strength and can withstand wind and snow loads.
Corrosion resistance: The steel plates are galvanized or coated with other chemical protective coatings to prevent algae growth.
Aesthetics: The corrugated roof steel plates have a unique appearance and a wide range of color options, which can enhance the beauty of the building.
Product Introduction
Four-wave roof sandwich panel is a kind of panel commonly used in building roofs. It consists of two layers of metal panels and insulation materials in the middle to form a "sandwich" structure. The surface is in four waves. It is widely used in various types of buildings due to its advantages such as insulation, high strength, lightness and waterproofness.
The panel is usually galvanized steel plate, aluminum plate or stainless steel plate, which is corrosion-resistant. It is widely used in the roofs and walls of large-span buildings such as industrial plants, warehouses, gymnasiums, etc.

Features
Wave design
There are four waves on the surface, which enhance the structural strength and drainage performance.
The wave design can also improve the load-bearing capacity of the board, which is suitable for large-span buildings.
Sandwich structure
It consists of two layers of metal panels and intermediate insulation materials.
The panels are usually galvanized steel plates, aluminum plates or stainless steel plates, and the core materials are usually polyurethane (PU), polystyrene (EPS) or rock wool.
Thermal insulation
The core material has good thermal insulation performance, effectively isolates heat and improves building energy efficiency.
Lightweight and high strength
Light weight, easy to transport and install.
The wave design enhances the strength and wind and earthquake resistance of the board.
Project Cases
Sandwich panels are widely used across industries, enhancing industrial construction, factory buildings, transportation, cold storage, and healthcare. They ensure durability, energy efficiency, and hygienic environments in projects like Jidong Intelligent Manufacturing New City, Qingzhou High-Speed Railway Station, Gold and Silver Valley Industrial Park, International Fresh Cold Chain Park, Hailier Pharmaceutical, and Boxing People's Hospital.
Flow Chart of Polyurethane
This diagram illustrates the polyurethane production process. It begins with unwinding, film covering, and pressing for shaping. Next, spraying, preheating, and foaming give the material its polyurethane properties. The material is then guided, cut to size, cooled for stabilization, and finally unloaded and packaged.
Our Factory
The various production lines within the factory work closely together, the distance between parts and components from one workshop to another is short, and the material flow is fast, which reduces the logistics cost of the production process and avoids additional costs caused by multiple loading and unloading.
Service
We provide support throughout the entire purchasing process. We offer on-site installation and consultation, extended warranties and replacement services to ensure a seamless and worry-free experience.
