Flexospan provides standard, even-profileC purlins and C girtsas well as custom profiles and punching patterns. We manufacture any component from 1/2" steel subgirts
to 12" section up to 10 gauge. Steel c purlins and c girtsare also available with other depths and flange widths.Contact Flexospan
for information onpurlin and girtstructural steel dimensions. Steel
wall girts androof purlins are manufactured
and sold onsite.
Roof purlins are used to support metal roofing panels. Wall girts are
used for the fastening of metal siding. They are available in stainless steel or galvanized, and can be prime painted and/or
coated in ZAM.
In this section you'll find sample calculations for determining wind and snow loads as well asC purlin and C girtweighttables.
Wind load (lbs/sq ft) x .75 x girt spacing (ft) x wind coefficient (typically
1.1) = Allowable load/linear foot of girt
20 psf x .75 x 5 Ft x 1.1 = 82.5 plf
Live (snow) Load
(load on purlin)
Snow load (lbs/sq ft) x purlin spacing (ft) = allowable load/linear foot of
purlin
20 psf x 5 ft = 100 plf
Note: These
sample calculations are basic. Many different variables can affect loading. For example, drift loading, building height, geographic
location, etc. Please contact Flexospan if special conditions exist.
