Metal composite material panels can be seen on the exterior of modern buildings around the world. The panels are durable, easy to fabricate and install, are low-maintenance, and budget-friendly. MCM panels are a popular choice for architects and general contractors. Composite materials have high dimensional stability and are able to keep their shape in different conditions. The demand for MCM panels continues to increase.
What is MCM?
Metal composite material is a type of cladding used to spruce up a building’s exterior, while providing a degree of thermal insulation and weather resistance. A variety of metals can be used for the outer ‘skin’ including aluminum, copper, stainless steel, zinc and titanium. Panels are formed by tightly bonding two metal sheets to a thermoplastic core.

Benefits of MCM
Metal composite material has many benefits for modern architectural design.
- MCM is sustainable. About 70% of an MCM by weight is recycled content. Most stock colors of coatings, paints, and finishes reflect heat and reduce energy use. The highly recyclable content can support LEED projects looking to qualify for an innovation credit.
- It has variety. Coatings for MCM can come in many finishes and colors, including multi-colored and custom. These include solids, metallics, decorative metals, shimmer effects, stone, and timber.
- The material is versatile. It bends and curves into various complex forms and shapes. These include many fabrication techniques such as bending, grooving, punching, cutting, rolling, and drilling.
- MCM is cost-competitive and affordable. This is due to advancements in manufacturing technology, improved fabricator efficiencies, and new installation techniques.
- MCM systems keep their curb appeal. The panels are durable and can withstand extreme weather. Their color and finish can last for decades.
- MCM helps save money. Panels can be installed much faster than alternative exterior products. The material is lighter than sheet metal, and less structural support is needed. Continuing improvements in paint finishes are also reducing ongoing maintenance costs.

Uses for MCM
Metal Composite Material has many different uses. In the construction industry, it is a key component of buildings, bridges, boat hulls, swimming pool panels, shower stalls, bathtubs and storage tanks. MCM is also good for interior design projects, including feature walls, partitions and ceilings.
MCM panels not only create beautiful facades, but also protect buildings from the elements. The exterior cladding can shield a structure from high winds, excessive rainfall, ice and snow. Many modern MCM panels contain fire-retardant chemistry that keeps flames from spreading. This is especially useful in high-rise buildings.
Composites Versus Traditional Materials
One advantage composites have over traditional materials is their high strength-to-weight ratio. Carbon fiber weighs about 25% as much as steel and 70% as much as aluminum. Composites are light, yet strong, and don’t rust. They are less costly to maintain and ensure long-term stability. Composites have opened up new design options and are now easier to produce. They are becoming a favored material in the auto and aerospace industries.
