Solar Mounting Systems
Engineered steel for solar.
Cold-rolled steel profiles and complete mounting systems for utility & commercial solar — fixed-tilt and tracker. 60+ years of steel expertise behind every structure.
Who we are
We engineer, roll & deliver solar steel.
Y Solar is the solar arm of Yılmaz Sac Profil. We point six decades of cold-rolling and cold-forming expertise — running since 1962 — squarely at the renewable-energy structures the world is building now.
We bring the discipline of a precision steel mill to mounting systems: tight tolerances, consistent coatings, and lead times a project can plan around. From coil to delivered array — we own every step, under one roof.
Mounting Systems
Two systems, one discipline
Fixed-Tilt Systems
Driven steel piles carry rolled top-chords that hold modules at a fixed angle — fast to install, low maintenance, engineered to the site.
- Configuration
- 1V · 2V portrait
- Tilt range
- 10 – 35 deg
- Foundation
- Driven C / Sigma / W
- Terrain
- Slope tolerant
Pile-driven foundations
No concrete on most soils — drive the pile, align the row and build the table.
Pre-punched assembly
Bolted through in-line punched holes — no field drilling, faster and truer on site.
Zn-Al-Mg coated
Pre-coated steel keeps sheared and driven edges protected for the life of the plant.
No motors, no maintenance
A fixed array has nothing to drive, power or service — set the rows, bolt them down, and the structure simply stands and produces for the life of the plant.
Tracker Structures
More than steel supply — we engineer the structural package for your tracker platform: posts, bearing supports, rails and brackets, calculated to your site loads and rolled to spec.
- Architecture
- Horizontal single-axis
- Rotation
- +/- 60 deg typ.
- Scope
- Posts, rails, brackets
- Coating
- Zn-Al-Mg / HDG
Drilled & driven posts
High-section piles sized for tracker wind loads.
Bearing & damper supports
Formed, punched brackets to platform spec.
Module rails
Light, stiff rolled sections for the table.
Every system ships engineered
Static report (Eurocode / ASCE 7) · GA drawings & BOM · pull-out test · installation manual — from one plant in Kayseri.
Product Range
Four core profiles, one system
Driven piles and structural beams that build the whole array — plus any custom section you need.
Foundation Pile
C-Piles
The primary driven pile for ground-mount arrays. The lipped C-section gives high bending stiffness for its weight and an open face that takes rails and brackets anywhere along its length.
- Section
- Lipped C
- Thickness
- 2.0 – 6.0 mm
- Width
- ≤ 400 mm
- Coating
- Zn-Al-Mg / HDG
Foundation Pile
U-Piles
An open channel pile for lighter loads and compact ground frames. Economical where a full C-section isn't needed, with a clean open face for fast bracket and rail connections.
- Section
- Open U
- Thickness
- 2.0 – 6.0 mm
- Width
- ≤ 400 mm
- Coating
- Zn-Al-Mg / HDG
Foundation Pile
Sigma Piles
A stepped sigma section with a rolled-in stiffening rib — more bending capacity and grip for deeper embedment in softer ground, while staying light enough to drive fast.
- Section
- Stepped sigma
- Thickness
- 2.0 – 6.0 mm
- Width
- ≤ 400 mm
- Coating
- Zn-Al-Mg / HDG
Structural Beam
W-Beams
Wide-flange structural beams for top chords, rafters and main spans where a pile alone won't carry the load. Supplied plain or with custom slotting for fast, adjustable connections.
- Section
- Wide-flange
- Sizes
- W6 · W8 · W10 · W12
- Material
- Grade 50 – 65
- Coating
- Hot-dip galv.
Custom sections
Any profile you can draw, we can roll — because we build our own forming tooling, bespoke sections become repeatable production runs. Catalogue parts are just the start.
Coating Technology
Zn-Al-Mg outlasts galvanized.
Our profiles roll from steel pre-coated with a magnesium-alloyed zinc-aluminium layer. The magnesium builds a dense, stable protective film that dramatically slows corrosion — and actively re-heals exposed cut edges.
Salt-spray / chloride exposure · indicative, varies by environment
Self-healing cut edges
A zinc-magnesium film re-forms over sheared and drilled edges that galvanizing leaves exposed.
Chloride & ammonia resistant
Built for coastal, agricultural and high-humidity sites.
Longer service life
Thinner coating, longer protection — lower lifetime cost.
Pre-coated, then formed
Uniform coverage with no post-galvanizing bath required.
Engineering & Site Adaptation
Designed to the site
Every structure is verified against the real environment it will stand in. We engineer to Eurocode and EN 1090, then roll the exact sections the calculation calls for.
Wind
Site wind zone and gust loads drive section, gauge and pile embedment.
Snow
Ground snow load and drift checked across span and tilt.
Corrosion
Atmospheric class sets the coating — Zn-Al-Mg for harsh sites.
Seismic
Connection detailing for ground acceleration where required.
Soil & terrain
Pull-out tests size the pile to the ground it's driven into.
Tolerance
Pre-punched holes keep the array true across long rows.
One calculation per project
No generic load tables — every plant gets its own static report, sized to its wind zone, snow load, soil class and seismic demand, then matched to the exact rolled sections.
Technical Reference
Sections & specs
Indicative ranges — final sections are sized to each project's load calculation.
