Galvanized Grille Standards

These codes and standards pertain to NFPA’s fire prevention codes, which evaluate and provide guidelines for equipment, materials, and safety solutions manufactured to suppress and prevent fires and the smoke that accompanies them. As with all of NFPA’s fire codes, they are revised every three to five years to remain current.

There are certain specifications that have been developed for hot-dip galvanizing in order to produce a high-quality coating. There are three main standards that govern the hot-dip galvanized steel, and a handful of supporting specifications that design engineers and fabricators should become familiar with to promote a high-quality coating and ensure their steel design is suitable for hot-dip ;The various standards that may apply to HDG rebar are shown in the box on page 64, HDG Rebar Standards, although ASTM A767 is the most common material specification in the U.S. Material galvanized to any of these standards might well be indistinguishable even to a trained observer, and the coatings might even be identical in metallurgical ;The duct gage tables are based on G-60 coated galvanized steel of lock forming grade conforming to ASTM Standards A653 and A924. Uncoated steel, prepainted steel, steel with metal coating such as aluminum or aluminum-zinc compounds, and stainless steel may be used if a minimum corresponding base metal thickness and material strength is provided.;Steel Standards. ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories ;D. Shop galvanized metalwork necessitating field welding which in any manner removes original galvanizing shall be restored by galvanizing repair in accordance with ASTM A780. E. Bolts and screws for attachment of galvanized items shall be galvanized in accordance with ASTM A153, or of compatible, non-corrodable material.;Galvanized metal containers are not considered safe for cooking or storage of food. The galvanizing process creates a coating to the metal that prohibits rust. This coating contains zinc, which can be toxic when consumed. Cooking utensils and storage containers are commonly not made of galvanized steel.

However, galvanized steel does not meet USDA food safe serving standards for acidic foods; like tomatoes, pickles, fish and fruit juices. Galvanized metal is not safe for cooking or storing food. Foods with low acidity do not react with the galvanized steel and, according to the USDA, are safe to serve on galvanized steel.;However, galvanized steel does not meet USDA food safe serving standards for acidic foods; like tomatoes, pickles, fish and fruit juices.

However, there are some exceptions to this standard (see thicker coatings below).;1.1 This specification covers grades of zinc alloys, commonly known as Continuous Galvanizing Grade (CGG) alloys that contain aluminum, or aluminum and lead and that are used in continuous hot-dip galvanizing of steel sheet. The compositions for CGG grades made from primary zinc are shown in Table 1.
