Metal corrugated sheets represent an innovative and reliable solution for both small- and large-scale constructions across agricultural, industrial and civil sectors.

Their versatility, lightness and high level of customization make them a preferred choice over traditional methods, offering numerous benefits in terms of efficiency, cost-effectiveness, sustainability, durability and aesthetics.

Versatility of Application and Customisation

Metal roofing systems based on corrugated sheets can be adapted to a wide range of design requirements. They can be installed on structures made of different materials such as timber, hollow-core concrete slabs, steel structures or reinforced concrete.
The COPERALL LG range allows roof constructions with variable slopes, from a minimum of 7% up to 100%, and enables sheet customization through multiple forming processes: straight, curved, ridge or shed profiles. This flexibility makes it possible to create aesthetically pleasing and functional roofing systems tailored to every intended use, from agricultural to industrial, civil and commercial applications.

Fast and Easy Installation with Clear Economic Benefits

Metal corrugated sheets are lightweight and modular, making installation simple and quick.
Customisable lengths and manufacturing precision facilitate installation, reducing laying time as well as labour and equipment rental costs. Furthermore, the dry-fixing installation system eliminates the use of mortars or adhesives, ensuring a clean, safe and immediately serviceable installation, with clear efficiency and economic advantages.

High Fire Resistance and Safety

Corrugated metal sheets are non-combustible and ensure safety in both public and private applications.
Their low weight also contributes to reduced seismic loads by limiting structural stresses and improving the overall stability of the building. Compatibility with insulation systems also allows the creation of sandwich roof assemblies to enhance thermal and acoustic performance, adapting to complex geometries and innovative architectural designs.

Lightness and Sustainability

Metal corrugated sheets are lightweight — up to 10 times lighter than traditional clay tile roofing — and approximately 15% lighter than bituminous or polymeric membrane systems. This significantly reduces the load on supporting structures and simplifies refurbishment works.
They are also recyclable and sustainable materials, manufactured from natural metals such as steel, aluminium and copper, which can be recovered and reused at the end of their service life, reducing environmental impact.

High Safety Performance and Cost Savings

Fire reaction Class A1 and external fire performance Class BROOF (t1, t2, t3) ensure protection in compliance with the latest fire-prevention guidelines for photovoltaic systems. Their mechanical strength and ease of installation drastically reduce installation time and costs.
The COPERALL LG range combines quality and cost-efficiency, delivering long-lasting solutions that maintain protective performance while lowering maintenance expenses.

Aesthetics and Design Flexibility

Thanks to customised processing and the possibility of creating curved, ridge or shed roofs, metal corrugated sheets deliver high-impact architectural results, integrating perfectly with the surrounding environment and enhancing the visual value of the structure.

In summary, metal corrugated sheets represent a modern and versatile solution for roofing and wall cladding: lightweight, resistant, easy to install and environmentally friendly.
Choosing these sheets means investing in a system that combines efficiency, durability and sustainability — ideal for projects designed to last over time and comply with current regulations.
