Life safety is the mantra of National Fire Protection Association (NFPA) 101 which is embraced by all in the fire protection industry. The approach to life safety has disseminated now into steel protection. Hot dipped galvanized members are being used more frequently in commercial buildings which require hourly ratings for fire protection.

Life safety is the mantra of National Fire Protection Association (NFPA) 101 which is embraced by all in the fire protection industry. The approach to life safety has disseminated now into steel protection. Hot dipped galvanized members are being used more frequently in commercial buildings which require hourly ratings for fire protection. Preparing hot dipped galvanizing that have been protected in accordance with ASTM A123 “Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products” for primer application require certain surface preparation techniques that will not compromise the galvanized layer yet allow the primer to bond to ensure a compatible surface for the intumescent fire resistive material (IFRM). The thickness of the water-based IFRM was determined by the massivity of the steel member.

Inspecting Hot-Dip Galvanized Steel

Product Number: 41216-960-SG
Author: Bernardo Duran
Publication Date: 2016
$20.00

Engineers, architects, DOTs, and other specifiers use hot dip galvanizing to provide corrosion protection to steel and iron in many industries, including transportation and highway, parking garages, bridges, structural, agricultural, petrochemical, and original equipment manufacturing. To ensure continued corrosion protection and structural integrity in these industries, it is necessary to properly inspect the galvanizing.

Lessons Learned for Painting Over Hot-Dip Galvanizing

Product Number: 51217-048-SG
Author: Kevin Irving
Publication Date: 2017
$20.00

This paper provides an introduction to the hot-dip galvanization process as an effective and important coating option and the necessary surface preparation steps for successful painting over hot-drip galvanized steel, also known as a duplex system. Proper practices and procedures must be used to prepare new and weathered zinc-coated surfaces on after-fabrication steel products for painting to improve the bond of paint to the zinc surface and provide long-term protection against corrosion.

Hot dip galvanizing steel articles after fabrication is one of the most widely used methods to provide corrosion protection. As a final step in the process, the hot dip galvanized coating is inspected for compliance with specifications. Correct measurement techniques and accurate interpretation of the results are necessary to provide an acceptable hot dip galvanized coating.
