ASTM A787
Standard Specification for Electric-Resistance-Welded Metallic-Coated Carbon Steel Mechanical Tubing
What it measures
Covers welded, metallic-coated steel tubing used as a mechanical member.
Why it matters for a panel envelope
It is the tubing the panel's steel is made from. The specification gives the typical framing member as 2 in × 1 in tubular galvanized steel, varying with the architectural and engineering specification for the project.
Guardian Shield™
The specification requires the light gauge galvanized steel integrated into the EPS to meet ASTM A787-05, with a typical framing member of 2 in × 1 in tubular galvanized steel.
