The Metl-Span striated wall panel is an attractive and economical alternative to typical flat wall panels. The exterior face is lightly profiled with narrow longitudinal striations and exhibits a virtual flat appearance from a short distance away. The wall panel is an exceptional value combining the aesthetics of a flat wall panel and high insulation ratings of a polyurethane core.
Note: Not intended for exterior walls on cold storage buildings.

Superior Insulating Value across the entire wall and roof area is assured with Metl-Span striated panels. The advanced polyurethane core provides enhanced insulation values that significantly lower heating and cooling costs.
One-Piece Construction process assures rapid completion of the wall and roof system. Factory fabricated composite panels are attached directly to the supporting structure and multiple steps to construct the insulated wall and roof are eliminated. Faster building completion means reduced construction and interim financing costs.
Lightweight yet Structurally Strong panels weigh only 2 ½ to 3 ½ pounds per square foot but are structurally strong enough for long spans that can significantly reduce costs for frame support.
Impermeable Faces & Built-in Thermal Breaks ensure the highest insulating values are maintained for the life of the building. Panels are manufactured with impermeable faces and when installed the insulation is completely encapsulated by metal trim that creates an impermeable membrane on all sides of the panel. The aged “R” values are comparable to the initial “R” values many years after the building’s original completion. Assured thermal values mean lower heating and cooling costs.
Class 1 Polyurethane Foam meets the requirements of the major model building codes for many types of construction. Unlike panels with expanded polystyrene cores they will not produce a self-propagating fire. Local building codes may require automatic fire suppression systems for most installations.
Concealed Attachment with clips and fasteners at the side joint of the panel offers a clean high profile appearance. No more barn like metal building looks.
Metl-Span striated wall panels are lightweight, yet very strong and durable attributing to reduced costs for erection and structural support.

|ARCHITECTURAL WALL PANEL ALLOWABLE CONNECTION LOAD WITH SIDE JOINT CLIP ONLY (PSF)|
|THICKNESS||PANEL SPAN (FT)|
- Based on CF-24, CF-30 and CF-36 panel with 22 ga. Flat exterior face & 26 ga. Light Mesa interior face (min Fy=33 ksi).
- Panel clips are fastened to min. 14 gage steel with (2) 1/4″-14 SDS Tek 3 at interior supports and (1) 1/4″-14 SDS Tek 3 at end supports. For 12 gage or thicker steel, #12-24 SDS and 1/4″-14 SDS Tek 5 may be used. In lieu of self-drilling screws, self-tapping screws may be used.
- Allowable loads based on panel stress, connection strength and deflection design criteria are derived from ASTM E72 structural testing.
- The allowable inward or outward loads is the smallest load calculated with a factor of safety of 2.5 for bending stress, 3.0 for shear stresses, 2.0 for connection and deflection limitation of L/180.
- The structural capacity of the supports are not considered and must be examined independently.
- Consult Metl-Span for recommendations on panel profile and gage suitable for thermal stresses.
