Gauge-or-Thickness-Guide.pdf

This is a Metal Finish Gauge or Thickness Guide technical specification document for a Middle School Roof Replacement project in Michigan. The document establishes minimum material thickness requirements for metal components used in roofing applications, specifically for coping caps, flashing, and fascia elements. The guide provides specifications for four different exposed face dimensions: 10" to 15", 8" to 10", 6" to 8", and up to 6" faces. Three primary metal materials are specified with corresponding gauges: galvanized iron (ranging from 20 GA to 24 GA depending on face size), aluminum 3003-H14 sheet (ranging from .080" to .040"), and cold-rolled copper (20 OZ to 16 OZ). The document notes that brakes should be added to stiffen coping caps where applicable, particularly for smaller face dimensions.

The specification document does not contain information regarding pricing terms, contract award dates, bidder meeting dates, response deadlines, or other commercial terms. The guide functions as a technical reference standard to ensure material quality and durability for the roof replacement project. Contractors bidding on this project would be required to meet or exceed these minimum thickness specifications when selecting materials for the roofing system components.
