Bossier City, La.-based McElroy Metal’s Cor-Ten AZP Raw is new to the company’s product line, offering the look of aged or weathered roofing and cladding.

Cor-Ten AZP Raw is a fluoropolymer coating system that uses cool pigment technology that McElroy Metal applies over Galvalume-coated steel sheet. It’s available in a variety of McElroy Metal standing-seam and through-fastened panel profiles. The look of aged or weathered roofing and wall cladding is growing in popularity and used in commercial, residential and industrial applications. Cor-Ten AZP Raw provides the appearance of rusted metal with the advantages of a highly reflective PVDF coating.

“We’re offering the appearance of weathered steel without having to wait for time and Mother Nature,” says Ken Gieseke, vice president of Marketing at McElroy Metal. “As soon as it’s installed, the weathered aesthetic is evident, attractive and durable. It’s sure to become a popular choice of architects and building owners seeking the look of weathered steel.”

In 2005, U.S. Steel introduced Cor-Ten AZP prepainted steel sheet to provide architects, building owners and homeowners with an enhanced performance product to its Cor-Ten steel. McElroy Metal offers the moderately weathered Cor-Ten AZP Raw, a carefully crafted and engineered system to provide any roofing or cladding project with the authentic look of timelessness.

Raw is produced by McElroy Metal in collaboration with Valspar and U.S. Steel.

Steel Sheet Meets Emissivity Requirements with Chromium-free Polymer Coating

U.S. Steel Corp. has expanded its Coated Steel Sheet family of products.

U.S. Steel Corp. has expanded its Coated Steel Sheet family of products.

U.S. Steel Corp. has added ACRYLUME E PLUS Coated Steel Sheet to its family of products. The new coated flat-rolled steel has a chromium-free clear emissive polymer coating and provides the quality and performance attributes inherent to ACRYLUME with improved thermal emittance.

ACRYLUME E PLUS offers the environmentally conscious metal building construction industry a chromium-free emissive acrylic coating on GALVALUME Coated Steel Sheet, which is designed to meet challenging solar reflectance and thermal emittance regulations. Prior to the introduction of this product, the emissivity requirements could only be met through pre-painted GALVALUME products. ACRYLUME E PLUS also meets numerous European Union environmental directives including Restriction of Hazardous Substances Directive (RoHS) and Registration, Evaluation, Authorization and Restriction of Chemical Substances (REACH).

The original ACRYLUME, which meets all current environmental guidelines in the United States, will continue to be available to customers for commonly used applications such as metal roofing and siding.

The new ACRYLUME E PLUS provides users with the same benefits as traditional ACRYLUME. ACRYLUME CF, ACRYLUME E PLUS minimizes staining and discoloration issues during storage, handling and installation. It does not require the application of lubricants prior to rollforming.
