Horizon Wall Panels

Mesa Smooth panels are produced with a standard Mesa profiled smooth steel face. These panels are an economical option for industrial and commercial walls, with added strength from a double Mesa profile for long panel lengths.

Highlights

Thin and light weight for ease of use or transport; cuts easily with common aviation snips
31-Gauge thickness, recommended for roof slopes of 3/12 pitch or greater
Corrugated panels will not rot, mildew or warp and can form an effective pesticide-free barrier against termites and other insects
Non-combustible; resistance to fire increases your security and may result in lower insurance premiums
Corrugated panels are a good choice for the environment; after a long service life corrugated panels are still 100% recyclable
21-1/2 in. roof coverage or 24 in. siding coverage
Galvanized steel is a low-maintenance product that is known for durability
Panel is unpainted

Table Notes:

Allowable loads were derived from tests conducted in accordance with ASTM E1592 and ASTM E72.
Allowable loads are calculated with a factor of safety of 2.0 for bending and shear.
Connection strengths reflect a standard fastener pattern – (@) 1/4” – 14 self drilling screw into minimum 14ga substrate. Other substrates must be designed separately. 2” wall panel utilize a flat clip. All other thicknesses utilize an angle clip.
Fastener capacity is based on manufacturer pullout/pullover data and are calculated with a safety factor of 3.0.
Allowable loads assume a minimum bearing of 2”.
Thermal Effects were not considered in analysis.
The structural capacity of the supporting members were not considered.
Bending/Shear and Deflection for 5” and 6” panels based on 4” capacity.
