The Fastensol 3550mm Silver Rail is the core structural component of the Fastensol mounting system, forming the horizontal support onto which solar panels are clamped. Manufactured from aluminium, it is supported by roof hooks at intervals of no more than 1.2m, with a pair of rails run horizontally per row of panels — spaced at roughly three-quarters of the panel height apart.
The rail is suitable for both pitched and flat roofs, and is compatible with tiled, slate, and sheet metal roof coverings via the appropriate roof hooks. Panels are laid across the rails and secured using end and mid clamps, and multiple lengths of rail can be joined using rail splice kits for longer rows.

Core Structural Rail
Forms the horizontal support structure for each row of panels, with a pair of rails run per row and clamped panels laid across them.
Hook-Supported Every 1.2m
Supported by roof hooks at intervals of no more than 1.2m, giving a well-distributed load path from the panels through to the roof structure.
Cladding Versatility
Compatible with tiled, slate, and sheet metal roof coverings via the appropriate roof hooks, with other roof mount types also available.
Extendable & Cuttable
Multiple lengths can be joined using rail splice kits for long rows, and the rail can be cut to length on site with a hacksaw or grinder.
High Wind & Slope Rating
Rated for roof slopes of up to 60 degrees, wind loads up to 60m/s, and snow loads of 2.0kN/m², suitable for buildings up to 20m in height.

Good to Know: For each row of panels, install a pair of rails horizontally, spaced at roughly three-quarters of the panel height apart, with roof hook supports at no more than 1.2m intervals.
What is the Fastensol Silver Rail used for?
It is the core mounting rail of the Fastensol system. A pair of rails is fitted horizontally per row of panels, supported by roof hooks, with panels laid across and clamped in place using end and mid clamps.
How far apart should the roof hooks be spaced?
Roof hooks should support the rail at intervals of no more than 1.2m to ensure adequate structural support along its length.
Can the rail be cut to length on site?
Yes. The rail can be cut to length using a hacksaw or grinder, allowing it to be sized to fit the specific roof and panel layout.
How do I join multiple lengths of rail for a longer row?
Use the manufacturer's rail splice kits, which connect two lengths of rail end to end to create a continuous run for longer rows.
What roof types is this rail suitable for?
It is suitable for both pitched and flat roofs, and is compatible with tiled, slate, and sheet metal roof coverings when used with the appropriate roof hooks.
