Free Metal Education and Technical Resources Available on MCA’s Website

The Metal Construction Association (MCA) offers several new technical bulletins and white papers on its website. MCA continues to update its Education/Technical Resources section on the website, addressing practical and educational topics related to the metal construction industry, including working with metal roofing, insulated metal panels, metal composite materials, fasteners, fabricating, machinery operation and many others. All technical resources are available for download as a pdf document at no charge.

New resources include:

    The technical bulletin “Roof Covering Repair Requirements and the International Code” offers input on what types of metal roof repair materials are required on an existing roof and what code supporting language exists. The two-page document briefly outlines the relevant portions of the 2012 International Existing Building Code for those who have questions about repairing a roof within code.

    “Choosing Between Fire Retardant and Standard Core Metal Composite Material” is a six-page white paper that clarifies the allowable uses for standard and fire retardant MCM in accordance with the 2006-2012 editions of the International Building Code. Developed by MCA’s MCM Fabricator Council, the paper includes detailed diagrams on several standard MCM core installation options.

    The six-page technical white paper “Insulated Metal Panels and NFPA 285” provides information on testing IMPs in accordance with NFPA 285. Specific IMPs have been tested and meet the conditions of acceptance of NFPA 285. This paper provides background on how when the “basic” IMP panel system meets NFPA 285, minor variations in items can be allowed without retesting or an analysis.

    “Proper Tools for Fastening Metal Panels” is a two-page technical bulletin that is intended to be a guide to proper fastening of metal panels to wood or metal frame buildings. Several illustrations indicate how to properly tighten fasteners and recommended tools are discussed.

Arkema Presents Technical Paper about Environmentally Safer Coating Systems

Arkema Inc. presented a technical paper on a high-performance, environmentally safer coating system for optimizing the protection of artistic and historic metalwork at the SSPC 2014 Conference on Feb. 11. SSPC 2014, held in Lake Buena Vista, Fla., serves as an international forum at which contractors, consultants, inspectors, engineers, paint/equipment manufacturers, and structure/facility owners exchange the latest research and technologies in the coatings industry. The event’s GreenCOAT technical program emphasizes innovations, the latest advances in eco-conscious coating technology, and developments for complying with green regulations.

With decreasing maintenance budgets, caretakers of our outdoor monuments, sculptures, and high-value architectural metalwork face formidable preservation challenges. In response to this urgent issue, the conservation community is continuously searching for more durable, low-maintenance coatings that provide longer-lasting protection against corrosion and degradation. Equally important, these new coating systems need to be environmentally safe, as increasingly stringent restrictions on volatile organic compound (VOC) emissions and solvent use are limiting available materials that can be used.

In his presentation on the restoration of historical architectural tiffany metalwork at the Philadelphia Museum of Art, Dr. Kurt Wood, a principal scientist in Arkema’s Fluoropolymers R&D Division, explained how Kynar Aquatec PVDF emulsion technology meets the critical needs of the conservation and architectural communities for durable, low maintenance coatings that are safer for the environment. His presentation reviewed the results from accelerated and natural weathering studies, historic architectural metalwork applications at the Philadelphia Museum of Art and the Rodin Museum, and a study of the candidate coatings by a group of experienced metal conservators from across the country.

“Researchers at Arkema Inc. continually strive to optimize PVDF-acrylic hybrid materials for different protective coating applications,” says Dr. Wood. “Ultimately, it is hoped that this collaborative work will serve as a guide to conservators, caretakers, and preservation professionals in implementing new strategies for optimizing the protection of high-value artistic and historic metalwork.”

Metal Roof Tile Eliminates Additional Battens, Purlins or Decking

The Platinum 78 metal roof tile system

The Platinum 78 metal roof tile system

Patented in more than 50 countries, the Platinum 78 metal roof tile system now is available in the U.S. The line eliminates the need for additional battens, purlins or decking. The product can span rafters or trusses at significantly greater spacing without additional support. In new construction applications, a 34-truss structural design can be reduced to nine trusses. The product weighs 2 pounds per square foot and can be installed on slopes as low as 2:12. The product offers aesthetics, energy savings and acoustic performance.
