Pitched Roof Mounting System

Solaracks pitched roof solar mounting systems cover corrugated and trapezoidal metal sheet, standing-seam roofs (Kliplok 700, Kliplok 406, Kalzip and locked seams), clay and concrete tile, and bitumen shingle. Each system uses 3–6 components in AL6005-T5 anodized aluminium with SS304 / A2-70 stainless fasteners, with L-foot, hanger-bolt, tile-hook, seam-clamp and railless attachment options. Every order is sized to site wind and snow load under ASCE 7-22 or AS/NZS 1170.2 (tested basis up to 70 m/s), SGS pull-tested, and covered by a 12-year warranty on a 25-year design life.

Systems by roof covering

Corrugated and trapezoidal metal sheet

L-foot rail mounts (SR-R5) and hanger-bolt mounts (SR-R9) fix through the sheet into the purlin or rafter, carrying the array on the structure rather than the skin. Self-tapped tilt triangles (SR-R6) lift modules to a working angle on low-slope roofs. The railless RUL bracket (SR-R2) replaces the L-foot-plus-rail chain for framed modules on trapezoidal sheet, sandwich panel and standing seam.

Standing seam and Kliplok

Claw seam clamps grip the folded seam directly — no penetration, no leak path (SR-R3). The railed version carries an H-profile rail across Kliplok roofs so module rows can bridge seams (SR-R4); the railless clamp mount seats module clamps directly on seam clamps with only three components (SR-R10); and the clamp triangle adds tilt on a seam roof with zero penetration (SR-R7).

Clay and concrete tile

Stainless steel roof hooks sit under the tile and carry rails and clamps — a fastening that suits nearly all tile coverings, including terracotta (SR-R8). A stainless trapezoidal bracket hook seats over the rib and fixes through the flank for light-profile roofs.

Bitumen shingle

An asphalt shingle flashing sheet with purpose-drilled L-feet, rails and clamps forms a sealed load path through the shingle layer.

Materials and corrosion protection

Rails, L-feet, clamps and brackets are AL6005-T5 anodized aluminium, available in clear or black anodizing; roof hooks, hanger bolts and fasteners are SS304 / A2-70 stainless steel. For ISO 9223 C4–C5 coastal and industrial sites, fastener grade and roof-screw coating are specified per project: coated roof screws have passed 1,000 hours of neutral salt spray, and the AL6005-T5 / A2-70 combination achieved a class 10 rating in SGS CASS salt-spray testing. How protection levels are selected site by site is set out in the ISO 9223 corrosion class guide and the Corrosion Protection Guide (PDF).

Wind and snow design basis

Rail profile (S, M or L), attachment spacing and module layout are derived from the site's wind speed and snow load under ASCE 7-22 or AS/NZS 1170.2; the tested basis extends to 70 m/s. Each project receives a stamped preliminary design and quotation within 24 business hours, with span tables and, on request, a full load calculation report for permitting. Roof slope limits are listed on each product page; the maximum roof pitch guide explains parallel versus orthogonal mounting.

Packing and delivery

Modular parts ship pre-assembled where the design allows, and every shipment is checked against its packing list with part labels and a load plan before dispatch, so an installer can break a container down by roof section. Mid clamps, end clamps, L-feet and grounding parts are interchangeable across the rail-based systems, which keeps a distributor's stock list short. Packing and labels can carry your brand under the OEM / ODM program.

Frequently asked questions

Which system suits a standing seam or Kliplok roof?

SR-R3 (rail on claw clamps), SR-R4 (H-profile rail for Kliplok) or SR-R10 (railless clamp mount). All three grip the seam without penetrating the sheet; profiles cover Kliplok 700, Kliplok 406, Kalzip and locked seams.

What wind speed are the pitched roof systems designed for?

Each order is sized to the site's design wind speed under ASCE 7-22 or AS/NZS 1170.2. The tested basis extends to 70 m/s; rail profile and attachment spacing change with the wind pressure and module size.

Can the systems be used on coastal C4–C5 sites?

Yes. Fastener grade and roof-screw coating are specified per site: coated screws are rated to 1,000 hours of neutral salt spray, and the AL6005-T5 aluminium with A2-70 stainless fasteners achieved a class 10 rating in SGS CASS testing.

What is needed for a quotation?

Roof type and covering profile, module size, site location, wind and snow load, roof slope and a layout or drawing. Solaracks returns the system, material grade, layout and packing approach within 24 business hours.
