Galvanized Structural Steel Specification

Astm a108 standard specification for steel bar carbon and alloy cold finished astm a123 a123m standard specification for zinc hot dip galvanized coatings on iron and steel products astm a143 a143m standard practice for safeguarding against embrittlement of hot dip galvanized structural steel products and procedure.

Galvanized structural steel specification.

The material categories covered in the specification include structural steel and plate strips and bars pipes and tubing and wires. There are three main specifications astm a123 a153 and a767 governing the coating thickness adherence and finish for hot dip galvanized steel and a handful of supporting specifications referenced in these specifications. The specification astm a123 a123m covers individual steel pieces as well as assemblies of various classes of material. Allied flo coat tube.

The specifications for the three most common types of galvanized tube and pipe are detailed below. Astm a123 a123m specification for zinc hot dip galvanized coatings on iron and steel products covers individual steel pieces as well as assemblies of various classes of material. Standard specification for steel structural tubing cold formed welded carbon zinc coated galvanized by the hot dip process a1063 a1063m 20 standard specification for steel sheet twin roll cast zinc coated galvanized by the hot dip process. Cold formed high frequency welded and hot dip galvanized.

A fabrication can have more than one material category such as a frame assembly. The six material categories covered in astm a123 a123m include structural shapes strip and bar plate pipe and tubing wire and reinforcing bar. 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. There are certain specifications that have been developed for hot dip galvanizing in order to produce a high quality coating.
