Steel

Maxalúme (Galvalume® - AZ50/AZ55) is a special type of galvanized steel made with an aluminum and zinc coating. It provides an ideal combination of corrosion resistance and durability. Available in acrylic-coated, 70% PVDF (Kynar 500®), SMP and Tedlar® PVF film finishes.

MagnaGuard™ (ZM150) is an aluminum-zinc alloy coated steel with the added strength of magnesium. Offering advanced corrosion and heat resistance to salt spray and humidity, this unique product is a great choice for coastal projects. Available coated with 70% PVDF (Kynar 500®)

​

Maxalume and MagnaGuard panels easily outperform regular galvanized steel in atmospheric corrosion and wind resistance tests. They also enhance fire protection and offer superior reflectivity and emissivity qualities, helping to reduce energy usage and related costs.

Aluminum

Aluminum is the lightest metal roofing material available. It is extremely resistant to corrosion from saltwater spray making it a smart choice in coastal environments. Aluminum naturally reflects light and remits heat keeping the building underneath cooler.  The excellent malleability of aluminum also makes it the metal of choice for more complex roofing profiles or designs. Available in painted 70% PVDF (Kynar 500®) and Tedlar® PVF film finishes.

Copper

We manufacture our CopperMax roofing panels using Revere Copper, the world’s leader in copper milling for over 200 years. This premium American-made copper is known for its beauty, superior surface quality and exacting physical properties. It is weather, wind and fire resistant, easy to install and virtually maintenance free. One of the most durable and long-lasting of roofing materials, copper roofs have been known to last for generations, aging gracefully with a striking greenish-blue patina.

PAINT COATINGS
70% PVDF formulated with Kynar 500®

Polyvinylidene fluoride (PVDF) is a fluoropolymer resin that when combined with the hardness of acrylic delivers a durable, high-performing coating system that withstands the test of weather and time. Kynar 500® or Hylar® 5000S based PVDF resins are the preferred choice of coating formulators thanks to their high resistance to extended UV exposure. Providing superior durability, color stability and stain resistance compared with SMP, premium PVDF finishes provide improved performance against water, humidity and high temperatures, oxygen and other atmospheric pollutants. Decades of testing demonstrate that PVDF offers peak performance when it makes up 70% of the overall metal panel coating. When comparing PVDF finishes, beware of less expensive formulations that contain only 50% PVDF, as performance drops off considerably. EMF proudly offers only premium 70% PVDF coatings formulated with Kynar 500® resins in dozens of premium and metallic colors. Custom colors are also available.

WeatherXL™ (SMP)

Silicone Modified Polyesters (SMP) coatings use a blend of polyester and silicon intermediates and offer a more economical option compared with PVDF. Long-lasting polyesters offer durability, particularly in the resistance to UV degradation and polymerized silicone improves gloss retention and reduces fading due to chalking. SMP coatings offer a harder finish making them more resistant to rough handling; however, this also makes them less flexible than other coatings which can lead to tiny fractures during roll-forming of panels. SMP finishes vary greatly in quality with the most important difference being pigment type. Extreme Metal uses WeatherXL™ SMP coatings from Sherwin Williams®  formulated using ceramic and inorganic pigments. Ceramic pigments, similar to those used in PVDF coatings, offer superior color stability, chalk and fade resistance, and better gloss retention over other SMP coatings. Standard and custom colors available.
