Writing Section 07 62 00: materials, standards and design constraints

How to name a metal, read a thickness in its own unit, ask for a finish and warranty, call for ES-1 edge testing, state movement and piece length, and check the result against what a shop can make.

You will be able to: Write Part 2 and the performance clauses so only one thing can be supplied: name each metal by designation and year, give thickness in the metal's own unit, ask for the finish and warranty, and state the wind test, the movement and the piece length.

Slide 1 of 12

Name the standard, year and title

UFGS lists each reference by organization, designation, date and title, for example SMACNA 1793 (2012) Architectural Sheet Metal Manual, 7th Edition.

Gelfand cites ASTM A 525 and ASTM A 93 with no year, so a reader cannot tell which edition is meant.

A designation with its year, and the title, says which document is meant.

Videos for this lesson

What this video shows: A 59-second clip of a coping pull-off under the ES-1 RE-3 method; its description quotes SPRI's opinion that ES-1 testing should be done on systems as manufactured by a given fabricator.

Video: ANSI/SPRI ES-1 Coping Pull Off - RE-3 Test by National ES Testing Service Tunney, on YouTube. Chosen from the video's published description.

Glossary

Gauge: A sheet-metal thickness number: a higher gauge number is a thinner sheet. The same number is a different thickness in galvanized and stainless steel, so a spec names the metal with its gauge.
ES-1: ANSI/SPRI/FM 4435/ES-1, the test standard for edge systems used with low-slope roofing. The 2022 edition tests copings and roof edge systems under simulated wind load.
Delta E: The color-change unit UFGS uses for finish fading. Its warranty counts fading of more than 5 Delta E as deterioration.
Expansion joint: A joint in a run of metal that lets it move with temperature. Each specification states its own maximum spacing: UFGS 32 feet for aluminum, Gelfand runs over 26 feet, University of Houston 10 feet.
