Epic Steel follows the national A.I.S.I. (American Iron and Steel Institute) specifications manual for tolerances in galvanized sheet metal.

All gauges conform to ASTM A792 and ASTM A653 Grade E (80,000 min. yield)/ or Grade D (50,000 min. yield) unless otherwise designated at time of order.

Application Details:

Minimum Slope Requirement: 3:12

Screw Application: #10 Wood grip fasteners are designed for use with dimensional lumber. #14 Wafer fasteners are designed for use with plywood sheeting, OSB and wafer wood (7/16” minimum thickness). #12 Tek screws are designed to be used with structural steel up to 3/16” in thickness.

Roof Application: Fasteners to be applied along the side of every rib and attached to each purlin, 2’ on center.  Please note that it is the responsibility of the builder to ensure that purlins are adequately spaced to meet specific engineering requirements.

EPIC Steel is neither partially nor solely responsible for improper installation or defects as a result of installation. Epic Steel recommends obtaining a color chip prior to placing an order. Please contact your Epic Steel representative to learn more.

This economical corrugated panel is perfect for interior and exterior applications. The 2 ½” Corrugated Panel has a single overlap system for vertical applications and a double overlap system for roofing applications. It is made in lightweight 28 gauge material, can be cut to length. The 2.5” corrugated is commonly used as a roofing application, as well as interior applications for garages, underneath patio’s, and custom design elements.

Attributes: Lightweight, Economical, Sleek design

  • 1 ½” Bearing Length
  • Load Span Tables Based on Working Stress
  • Flexural Design analysis according to AISI “Specification for the Design of Light Gauge Cold-Formed Steel Structural Members” May 1981
  • Continuous Span Loading applies to sheets continuous over 3 or more spans
  • Weight of sheet has not been allowed for when calculating live load and uplift.
  • Deflection (L/180) limiting live load based on deflection of span.
  • Metal thickness based on minimum ASTM specifications for allowable load calculations
  • Loads may be increased by ⅓ for wind loads

Areas of discontinuity are subject to higher spikes in wind pressure, therefore a different coefficient in wind pressure will need to be considered and multiplied by a factor of 1.5
Data from: 1994 UBC Table 16-F

Note: The load tables have been compiled for the design of steel roofing and siding used in conjunction with either wood or steel framed structures.  EPIC Steel assumes no responsibility, either expressed or implied, for its use.
