Short answer: Cast iron scrap in Abu Dhabi is bought as its own grade, separate from steel, because it is brittle and melts differently. Machine beds, plant engine blocks, pump casings, valve bodies, manhole covers and counterweights all qualify. The rate depends on how clean the castings are, what is still bolted to them, and their size.
Cast iron is the heaviest thing most plants own and the last thing anyone thinks to sell. A lathe bed sits behind the workshop for six years. A pump casing gets replaced and the old one goes on a pallet by the fence. Valve bodies collect in a container after every shutdown. When a site finally gets around to selling cast iron scrap in Abu Dhabi, the question is usually the same: is this just steel, and why does the buyer keep asking about it separately?
It is not steel, and the difference shows up in your rate. This article explains what counts as cast iron, why it is graded on its own, and how to get it ready so the load is worth what it should be.
Where cast iron turns up in a plant
Iron is cast when the part needs mass, stiffness and resistance to vibration more than it needs to bend. That gives you a fairly predictable list.
Heavy castings from machines and plant
- Machine beds and frames: lathes, milling machines, presses and grinders sit on cast iron beds because iron soaks up vibration.
- Engine blocks from plant: generator sets, fire pump engines and compressor drive engines. These are industrial engines, not car blocks, and many weigh well over a tonne.
- Pump casings and volutes: the outer shell of most centrifugal pumps used for water, cooling and process duty.
- Valve bodies: gate, globe and check valves on water and utility lines, often with brass or bronze trim inside.
- Gearbox housings, flywheels and motor end shields.
Civil and site castings
- Manhole covers, frames and gully gratings left over from utility and road works.
- Counterweights: forklift counterweights and the filler blocks in lift counterweight frames are usually solid cast iron.
- Old cast iron pipe and fittings from drainage replacement.
One note on manhole covers: sell only what is yours. Surplus stock from your own store, or covers removed under a contract that hands the old ones to you, is fine. Keep the paperwork that shows it, because we ask for it.
Why is cast iron its own grade and not mixed steel?
Cast iron carries far more carbon than steel, roughly two to four percent against well under one percent for most structural steel. That carbon is what makes it pour well into a mould, and it is also what makes it brittle. Hit a steel beam and it bends. Hit a cast iron bed hard enough and it cracks.
That matters in two places. First, at the melt. Foundries melt cast iron back into new castings, and steel mills can only take it in measured amounts because the extra carbon has to be dealt with in the furnace. So cast iron goes to a different buyer, or into a different charge, than the sorted steel we send back to UAE mills such as Emirates Steel (EMSTEEL), Arabian Gulf Steel Industries and Jindal SAW Gulf.
Second, at the yard. Because it breaks instead of bending, cast iron is prepared differently. You do not shear it, you break it. Oxy-fuel cutting, which works so well on steel, struggles on cast iron. A heavy casting mixed into a steel load either lowers the grade of the whole load or has to be picked out by hand, and that labour comes off somebody's rate.
Keeping cast iron in its own pile is the single easiest thing you can do for the price.
Grey iron or ductile iron: does it matter?
Most of what comes out of older plant is grey iron. Newer valve bodies, pipe and many manhole covers are ductile iron, also called nodular or SG iron. Painted, they look much the same.
| Feature | Grey iron | Ductile iron |
|---|---|---|
| Typical items | Machine beds, older pump casings, engine blocks, flywheels | Newer valve bodies, pressure pipe, manhole covers, some counterweights |
| How it breaks | Snaps cleanly, grey crystalline face | Bends a little first, then tears |
| Ease of breaking to size | Easy with a drop or breaker | Harder, takes more effort |
| How we grade it | Cast iron grade | Usually cast iron grade, sometimes kept apart in large clean lots |
For most loads you do not need to separate them. If you have a large, uniform batch of one type, for example a store full of ductile valve bodies of the same pattern, tell us. A clean single-type lot is easier to sell on and that shows in the quote.
How is cast iron scrap graded at our yard?
We look at three things: what else is attached, what is on or inside it, and how big each piece is.
Attachments, oil and other metals
A pump casing with the bronze impeller still inside, a motor still bolted to a gearbox, a valve body with brass trim: each of these is two or three metals in one piece. The cast iron is worth more once the non-ferrous parts come out, and the brass or bronze is worth more on its own. If your team can strip them, do it. If not, we can, but the rate reflects the work. Our guide to valve trim and other brass parts explains how those come off.
- Oil: engine blocks and gearbox housings must be drained. Used oil is hazardous waste in Abu Dhabi and goes to a licensed handler under the rules set by Tadweer, the emirate's waste authority, and the UAE Ministry of Climate Change and Environment.
- Grout and concrete: machine beds are often grouted to the floor. Concrete stuck to the base is dead weight that we cannot sell.
- Rubber linings and plastic: pump linings and seals come out before weighing where possible.
Size and breaking
Foundries take cast iron in pieces they can charge. A two-tonne lathe bed has to be broken before it is useful to them. We can do that in our yard, so you do not have to break it on site. What helps is knowing the sizes before we come, so the right truck turns up.
Cast iron borings and grinding swarf from machining are a different product again. They are covered in our article on turnings, borings and production offcuts.
Getting heavy castings off site
We run 8 trucks, two of them fitted with hiabs for heavy single pieces and two hydraulic skip trucks for loose castings like valve bodies and manhole covers. Our crew can cut away steel frames, unbolt and lift on your site. The hazard assessment and the working method are agreed with you before the truck arrives, under our ISO 45001 system.
If a casting is too heavy for a hiab, tell us early. Usually the answer is your own crane or forklift on the day, planned in advance rather than discovered at the gate. If the cast iron is still inside a whole machine you want gone, our page on selling complete machines for scrap covers that route.
Every load is weighed, and you get the weight, grade and rate on paper. The price we quote is the price we pay, with nothing quietly deducted at the weighbridge. We collect across Musaffah, ICAD and KIZAD.
What to send us for a quote
- Photos of the castings, with something in the frame for scale.
- A rough count and type: beds, blocks, pump casings, valves, covers, counterweights.
- Whether non-ferrous parts, oil or grout are still on them.
- Where they are on site, and whether a forklift or crane is available.

Common questions
Is cast iron scrap bought at the same rate as steel?
No. Cast iron is graded on its own because its high carbon content means it melts and sells differently from steel. Clean, separated cast iron is easier to place with foundries, which is why we quote it apart from your steel.
Do I need to remove the bronze impeller from a pump casing?
It helps but it is not required. A casing with the impeller removed grades as clean cast iron, and the bronze goes into its own higher grade. If it stays in, we strip it in our yard and the rate reflects that work.
Can you collect a machine bed that weighs several tonnes?
Often yes. Two of our trucks have hiabs for heavy single pieces, and our crew can unbolt and lift on site under an agreed method statement. For pieces beyond a hiab, we plan the lift with your crane or forklift before the day.
What do you need before collecting engine blocks?
They must be drained of oil and coolant. Used oil is hazardous waste in Abu Dhabi and must go to a licensed handler under Tadweer rules. Dry blocks can then be weighed and graded as cast iron.
Can we sell old manhole covers from a project?
Yes, if they belong to you, for example surplus stock or covers handed over under your contract. We ask for paperwork that shows where they came from. Covers from a public road without that are not something we take.
