6 FAQs about [Specifications for punching holes in photovoltaic panel purlins]

What is a purlin through hole clamp?

Bottom access, Purlin Through Hole clamps are Type 304 Stainless steel for higher strength and durability. The clamp allows for direct PV module mounting to purlins and other structural members. The patented pre-assembled clamps eliminate handling small parts on the job site and provide for a faster installation.

What size bridging is required for a purlin roof?

Alternative hole sizes, shapes and centres are possible, subject to enquiry. Stramit recommends that bridging be installed such that the maximum unbraced length is 20 x D (where D is the purlin web height), or 4000mm whichever is the least. In addition to enhancing purlin performance this requirement assists with the erection of roof sheeting.

What is the bolt strength of a roof purlin?

The bolt strength grade (4.6 or 8.8) should be specified by the design engineer to conform with the Stramit® Purlins, Girts & Bridging – Product Technical Manual. Loads to be suspended from roof purlins must be accounted for in design. No allowance is included in the capacity tables.

How do you dimension a purlin?

The preferred method of dimensioning is hole centre to hole centre rather than referenced from one end. An overall purlin length is also desirable to provide a data entry dimension check. Stramit normally supply purlins and girts punched to conventional AISC hole centres.

Why do large purlins require large bridging systems?

Large purlins require large bridging systems due to the larger spans and heavier loads encountered. These bridging components are conventional in nature but on a much larger scale. Generally the bridging channel is a C150 section firmly bolted to end plates to suit the particular purlin concerned.

How do you bolt a purlin roof?

Purlin laps must be bolted in the top web hole and the lower flange holes at both ends of the lap. Bolting only the web of lapped purlins does not provide full structural integrity and excessive loads can be placed on the roofing screws that penetrate both purlin thickness in the lap region.
