Stormshield Xt-40, Energy Star® Rated, Silicone Modified Polyester
Available Material Type
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.
Minimum Slope Requirement: 11/2:12
Screw Application: [detail_p title="Roof Application"]Fastener Spacing: 24″ and 36″, refer to engineering specifications for proper clip spacing and substrate specifications.
Roof Application: Fasteners to be applied along side every rib and attached to each purlin, 2’ to 5’ 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.
A sturdy commercial grade product that can free-span between purlins up to 5 feet. The PBR panel has a full under lap purlin leg and a five-degree over bend on the overlap creating an anti-siphon groove for a waterproof system at low slopes. This Panel is made standard in 26 gauge, can be cut to length, and is available in 1-2 day’s.
Attributes: Low Slope Requirements, Fast Turnaround, Large Free-Span potential.
- 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
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.
Simple Span: gives load specifications on a single length panel fastened at either end of the panel (essentially free spanning the length in question).
Continuous Span: gives load specifications on a single panel with at least 3 additional fastenings between either end of the panels. Load limits are given in Lbs. per Sq.Ft.
”Wind: 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
