Renewables fabrication

The steel under every kind of clean power.

Tracker parts and access for solar; fixtures, tower internals and nacelle frames for wind; and the steel for hydro, geothermal, hydrogen, storage, marine energy and carbon capture, made to your drawings in our own works.

Renewable energy

Built for a pipeline of sites.

Renewables is repeat work at scale: the same part, bracket or platform, thousands of times, every one fitting like the first. That is what our lasers, punching and robotic welding are for.

We work with developers, turbine makers and integrators including Adani Renewables, Adani New Industries, Suzlon Energy, Kee Safety (UK), Sterling Renewables and Zetwerk. The design and the equipment are theirs; the steel is ours.

Solar, wind and storage, connected.

Around the solar blocks, which are the developer’s, sit our inverter skids; batteries and a hydrogen module sit beside the substation that exports it all; turbines turn to the east, with the factory that builds them. Hover any steel to see what it is; click to open its page.

How the sector works

From the sun and the wind to the grid.

Power is made from the sun, the wind, water, the earth’s heat, biomass and the sea; it is stored in batteries or turned into green hydrogen, and exported through substations, while carbon capture cleans up what remains. Every stage stands on fabricated steel. This is where ours goes.

  1. Solar 01 Solar parks & rooftops Tracker parts, rooftop safety and access.

    The modules and their mounting structures are the developer’s. We supply parts into them: tube connector preassemblies and slew drive seats for trackers, base plates for rooftop lifelines and handrails, walkways and stairs between arrays, and inverter skids.

    5 products
  2. Wind 02 Wind, onshore and offshore Towers, nacelles, foundations and their factories.

    Towers carry platforms and ladders inside; nacelles have a steel skeleton under the casing; offshore, turbines stand on monopiles, transition pieces and tripods.

    8 products
  3. Hydropower 03 Hydropower Intakes, penstocks, gates and powerhouses.

    Water enters through trash racks, drops down steel penstocks on ring girders to the turbines, and is controlled at the spillway by radial gates.

    4 products
  4. Geothermal & Biomass 04 Geothermal & biomass Wellheads, exchangers and fuel handling.

    Geothermal plants draw steam from wellheads through heat exchangers; biomass plants store pellets in silos and burn them in boilers. Both need access and support steel.

    4 products
  5. Hydrogen & Storage 05 Hydrogen & storage Electrolysers, hydrogen tanks and batteries.

    Green hydrogen is made in electrolysers and held in pressure vessels; batteries sit in containers on skids, under canopies, beside EV chargers.

    4 products
  6. Tidal, Wave & Ocean 06 Tidal, wave & ocean thermal Energy from the sea.

    Tidal turbines stand on seabed frames; wave devices anchor on tripods; ocean thermal plants run on large heat exchangers.

    3 products
  7. Carbon Capture 07 Carbon capture Capture units, pipelines and storage.

    CO2 is captured in absorber columns inside steel structures, compressed and carried on pipe racks and supports to storage.

    3 products
  8. Grid & Access 08 Grid & access Substations, and safe access everywhere.

    Everything connects to the grid through substations on steel gantries, and every roof, tower and plant needs walkways, stairs and guardrails.

Where our steel goes.

Solar parks & rooftops: tracker parts, rooftop safety and access

The modules and their mounting structures are the developer’s. We supply parts into them: tube connector preassemblies and slew drive seats for trackers, base plates for rooftop lifelines and handrails, walkways and stairs between arrays, and inverter skids.

Wind, onshore and offshore: towers, nacelles, foundations and their factories

Towers carry platforms and ladders inside; nacelles have a steel skeleton under the casing; offshore, turbines stand on monopiles, transition pieces and tripods.

Hydropower: intakes, penstocks, gates and powerhouses

Water enters through trash racks, drops down steel penstocks on ring girders to the turbines, and is controlled at the spillway by radial gates.

Geothermal & biomass: wellheads, exchangers and fuel handling

Geothermal plants draw steam from wellheads through heat exchangers; biomass plants store pellets in silos and burn them in boilers. Both need access and support steel.

Hydrogen & storage: electrolysers, hydrogen tanks and batteries

Green hydrogen is made in electrolysers and held in pressure vessels; batteries sit in containers on skids, under canopies, beside EV chargers.

Tidal, wave & ocean thermal: energy from the sea

Tidal turbines stand on seabed frames; wave devices anchor on tripods; ocean thermal plants run on large heat exchangers.

Carbon capture: capture units, pipelines and storage

How we work

Repeat parts, identical.

Scope can start at your drawing and finish bundled for the site. Open any stage for what it covers.

Talk to an engineer
Design to your drawings

We fabricate to the developer’s or designer’s drawings, and check them with you before steel is cut.

Cutting & punching

Fibre lasers up to 20 kW, CNC punching and a robotic beam cutting cell, so repeat parts are identical.

Forming

Press brakes up to 600 T and 8 m, and plate rolls to 40 mm, for brackets, door frames and rings.

Welding

Robotic and certified manual welding to EN ISO 3834-3 and EN 1090.

Finish

Blast, prime and paint in house; galvanised finishes on request.

Bundled for site

Parts marked and bundled by row or tower, in the order the site installs them.
