Ultra-Clad™ KYNAR®/HYLAR® pre-finished steel is our premium grade in coil and sheet product and is the industry standard for commercial applications. This high performance product offers the ultimate resistance against weathering and fading and is backed by our 30 year non-prorated finish warranty. Featuring Dura Coat Product’s Durapon 70 full strength HYLAR 5000® paint finishes, Ultra-Clad is available in a wide variety of gauges and sizes and is stocked in 34 standard colors. All standard Ultra-Clad color formulations utilize Cool technology pigments and are Cool rate. Custom colors are also available upon request.

Silicon Modified Polyester

Dura Coat Products XT40S siliconized polyester (SMP) paint finishes offer a high quality, lower cost alternative to the full strength HYLAR 5000® paint finishes. This product has excellent weathering characteristics and is covered under our standard 30-year finish warranty. This finish is currently stocked in a selection of colors, identically matching our KYNAR/HYLAR colors and is able to be color matched to all standard or custom colors. All standard Ultra-Clad SMP color formulations utilize Cool technology pigments are Cool rated.

Polyester

Our polyester paint finish offers a cost efficient alternative to our high-end paint systems. This product is typically used for light gauge rainware, trim and flashing products or areas protected from direct weathering, such as soffits and interior applications. Custom color matching is available

Galvalume® Cold Rolled Sheet

What is Galvalume®?

Galvalume is an engineered coating consisting nominally of 55% Al, 43.5% Zn and 1.5% Silicon. It was developed to combine the galvanic protection of galvanized coatings with the barrier protection of aluminized coatings. The result is an economical, highly corrosive resistant coating with superb heat resistance and reflectivity.

Why use Galvalume?

Galvalume is ideal for applications which require superior corrosion performance (compared to G90 galvanized) or when high reflectivity and temperature oxidation resistance is needed. Galvalume resists discoloration when subjected to temperatures up to 600°F.

The excellent corrosion protection provided by the Galvalume coating allows CMG to warranty our product against perforation for 20 years and 6 months on AZ50 coated material and 25 years and 6 months on AZ55 coated material. Please contact your CMG representative for further details.

In addition to being corrosion resistant, the highly reflective surface of Galvalume sheet helps lower air conditioning cost during summer months. These qualities make Galvalume the ideal roofing material.

Current uses for Galvalume

Examples of applications currently utilizing Galvalume include:

  • Metal roofing and siding
  • Walk in refrigerator panels
  • Patio furniture
  • Doors or door frames
  • Grain storage bins
  • Farm machinery
  • Piping
  • Appliance brackets and panels
  • Ductwork
  • Chimney pipe
  • Exhaust system components
  • Heat shields

Unacceptable Applications

Not all applications are ideal for Galvalume. In some cases, CMG advises against the use of Galvalume or, at a minimum, taking appropriate measures to prevent corrosion. Examples of applications that may compromise the useful life of the product include:

  • Environments where there will be direct contact with lead, graphite, cement, copper, run off from copper flashing and/or piping, or treated lumber.
  • Severely corrosive environments such as repeated exposure to harsh chemicals, animal confinement buildings or contact with seawater.
  • Perforated or expanded metal sheet
  • Parts requiring right radius bends of less that 2T for sheet thickness of .030″ and under and bends less than 4T for sheet thickness above .030″
