Z450 is also available on request.
Roof purlin z purlin span table.
The tables also provide ultimate load capacities for gravity load wind uplift and for deflection limits of span 180 and span 150.
Steel z purlins and z girts are also available with other depths and flange widths.
By the standard the most used placement of purlin span for metal roof is five foot intervals.
Z and c20024 purlin span table single span span inward load outward load deflection.
Standard secondary framing consists of cold formed z shaped roof purlins and wall girts.
For 2x4s purlins the posts are spaced in 4 feet distance.

Purlins and girts are manufactured from high tensile steel for increased strength and reduced weight.
Z and c members are shop punched for simple field bolted connections.
Lapped span design capacity tables including continuous are based on a 15 lap.
Tables include simple continuous lapped and combination spans allowing a comprehensive range of spanning options.
This means that the final roof support system appears to be one unbroken purlin providing efficiency and durability.
Strong and lightweight our z purlins span upwards of 25 feet depending on the roof load and how spaced out the z purlins are.
Where span lengths are unequal eg reduced end spans each purlin should have 7 5 of each adjacent span added as the lap length on that spans side of the support.
If the space between posts is greater than 8 feet then brace is needed to avoid buckling.
C shaped wall girts may be used for framed openings and other special applications.
Offering robustness and flexibility z purlins are a traditional yet effective system of sheet support that are easier to install and handle than traditional timber.
Stramit generally recommends a lap length of 15 of the span.
Additionally z purlins can be nested together as a splice in roof construction.
Purlin load tables load tables provide unfactored gravity load capacities which are based on the lesser of the purlin working load capacity or as controlled by a deflection limit of span 180.
For 2x6s purlins the posts are spaced in 6 feet distance.
We manufacture any component from 1 2 steel subgirts to 12 section up to 10 gauge.
Z and c members are available in 8 10 or 12 inch depths.
