Your Corrugated Sandwich Panel Solution
Corrugated Sandwich Panel with corrugated structure is composed of high-strength metal panels and high-efficiency insulating core (PU, PIR, or EPS), which is suitable for industrial plants, warehouses, and buildings with large roofs and walls. The corrugated design makes the panels stronger and more load-bearing, allowing them to span larger spans, which reduces the number of supporting structures and therefore the cost of steel. The insulation core provides consistent heat retention, which helps reduce the building’s energy consumption.
The panels are pre-fabricated and designed for quick installation, which can significantly reduce construction time, labor costs, and construction risk. Pupanel offers material selection, production processes, and customization to the thicknesses, lengths, and finishes you need for your project.

Corrugated Design Makes Roofs More Stable
The corrugated structure of Corrugated Sandwich Panels increases their flexural rigidity and load-bearing capacity. For large-span roofs, the number of steel supports can be reduced, thereby lowering material costs and construction complexity. For example, for a factory building with a span of 12 meters, the use of corrugated sandwich panels reduces the number of support beams by about 20% compared to ordinary flat panels, and the construction time can be shortened by about 15%.
Integrated Insulating Core Saves Energy Costs
PU, PIR, or EPS cores built into the panels provide efficient thermal insulation and keep the room temperature stable. In cold rooms or factories, indoor temperature fluctuations can be controlled to ±2°C, reducing air-conditioning or heating loads. In cold rooms, for example, using PIR corrugated panels can reduce energy consumption by about 10-15% per year, saving US$3-5 per square meter. The panels are better insulated than traditional walls and can be constructed faster, allowing large enclosures to be completed quickly.
Wind and Water Resistance for Longer Service Life
The corrugated design and high-strength metal panels increase the resistance of roofs and walls to wind and water pressure and accelerate rainwater drainage, reducing water pooling and leakage. Tests have shown that roofs with corrugated panels remain stable at wind speeds of up to 35 m/s, and water ponding is about 30% lower than that of ordinary flat panels, reducing maintenance costs. Combined with weather-resistant metal panels and long-lasting coatings, roofs and walls have a service life of more than 20 years, providing a reliable, long-term building envelope for factories, warehouses, and cold stores.

EPS cores are lightweight, low-cost, and suitable for general plant and warehouses.
Rock Wool and Glass Wool are both fireproof and soundproof, suitable for public buildings or clean rooms.
The choice of core material should be based on building use, span, fire rating, and acoustic requirements to ensure performance meets requirements and costs are controlled.
Corrugated sandwich panels can span 6-12 meters and have a load-carrying capacity in accordance with ASTM C393 and EN 14509. Using large spans reduces steel bracing by about 15-20%, lowering material costs and construction complexity.
Corrugated Sandwich Panels should be secured at the seams and bracing locations per the design drawings, and sealed for waterproofing. The installation order is typically roof first, then wall, to ensure even support. Pupanel provides installation instructions and on-site technical support to improve construction efficiency.
Corrugated sandwich panels comply with ASTM C393, EN 14509, CE, and ISO standards, and are suitable for industrial plants and public buildings, as well as cold-chain and clean-room facilities, with PIR or rockwool cores that can achieve fire ratings of B1-A2. The use of these panels eliminates the need for secondary certification and ensures project compliance.
Corrugated Sandwich Panels are lightweight and can be up to 12 meters long, making them easy to handle and reducing on-site labor. During transport, the panels should be stacked vertically along the corrugation direction and secured to prevent deformation or scratches, ensuring stable performance upon arrival.
What Is a Corrugated Sandwich Panel?
A corrugated sandwich panel is a construction material made of a high-strength metal panel and a heat-insulating core. It differs from standard flat sandwich panels by having a corrugated surface, which increases load-bearing capacity and improves drainage. Corrugated sandwich panels are commonly used in industrial plants, warehouses, cold storage, clean rooms, and on the roofs and walls of commercial buildings.
Principle of Corrugated Sandwich Panel
Corrugated Structure
The corrugation shape enhances the panel’s bending resistance and load-bearing capacity. It can be understood that the corrugation is like the arch structure of a bridge, which spreads the weight over the whole panel so that the same thickness of the panel is stronger. The bending stiffness of corrugated sheets is 20-30% higher than that of flat sheets, enabling roof or wall spans of 6-12 meters, reducing the need for structural steel support and lowering material costs. The grooves in the corrugated sheet direct rainwater quickly to the drainage outlets, reducing water accumulation and leakage and improving the roof’s durability. The corrugated structure also keeps the panels stable in windy conditions, making them ideal for industrial plants and large warehouses.
Core Material
The core of corrugated sandwich panels is the insulation material, commonly PU, PIR, EPS, rock wool, or glass wool. The core material provides thermal insulation, fire protection, and sound insulation. It can keep the indoor temperature stable and reduce cooling and heating energy consumption, for example, using PIR core material of cold storage, each square meter can save 3-5 U.S. dollars per year in energy costs. PIR and rock wool fire rating up to B1-A2, meet the fire requirements of industrial factories and public buildings. Rock and glass wool also reduce noise and are suitable for clean rooms or office areas.
Pupanel has a sophisticated production line and strict quality control, with complete production and inspection records for each panel. With 20 years of experience in industrial building materials, we can provide customized solutions to meet the needs of different projects.
