Choosing the right hydraulic shear is one of the most important equipment decisions a scrapyard operator can make. Buy too small and you create a processing bottleneck that limits your throughput and frustrates your team. Buy too large and you are paying for capacity you do not need, with higher running costs to match.
Getting the right size scrap metal shear from the outset saves money, reduces downtime, and keeps your operation running efficiently. At JMC Recycling, we have been helping scrap metal businesses find the right equipment since 1872, and the same core questions come up every time. This guide walks you through them.
Why does hydraulic shear size matter?
A hydraulic shear that is too small for your operation will struggle with heavier sections, wear its blades faster, and slow down your processing line. One that is oversized for your typical material will cost more to run, take up more space, and may be harder to justify on return on investment grounds.
Getting the size right means you process more scrap metal in less time, produce cleaner and more consistent cuts, and extend the working life of the machine. It also means your scrap is better prepared for transport and more attractive to steel mills, which directly affects the prices you can achieve.
According to the World Steel Association, every tonne of scrap used in steel production avoids the emission of 1.5 tonnes of CO2, making well-prepared scrap an increasingly valuable commodity.
What material are you cutting?
The starting point for any hydraulic shear sizing decision is the material you process most frequently. Different materials place very different demands on a scrap metal shear.
Light gauge material
Light gauge material such as thin-walled tube, small diameter rebar, and mixed light scrap requires relatively modest cutting force. A smaller hydraulic shear can handle this type of material efficiently and cost effectively.
Alligator shears are typically better suited to lighter sections such as rebar, pipe, and angle iron, while larger hydraulic shears handle heavier structural material
Medium sections
Medium sections including angle iron, box section, and general structural steel require more cutting force and a larger jaw opening to accommodate the material. This is the bread and butter of most scrap yards, and the majority of mid-range hydraulic shears are sized around it.
Heavy sections
Heavy sections such as thick-walled pipe, heavy steel beams, and large structural components require significant cutting force and a correspondingly larger machine. Attempting to cut heavy sections on an undersized scrap shear is one of the most common causes of premature blade wear and hydraulic system strain.
If your yard processes a wide mix of material types and sizes, it is worth sizing your hydraulic shear around the heaviest sections you regularly handle rather than the average, since those are the cuts that will push the machine hardest.
What levels of output does your scrapyard need?
Volume is the second key important thing to note. How much scrap metal do you need to process in a typical day, and how does that translate into cuts per hour?
The UK metal recycling sector processes approximately 11.5 million tonnes of ferrous and non-ferrous metals every year according to the BMRA, underlining the scale of demand for reliable, correctly sized processing equipment.
A smaller independent scrapyard processing modest volumes of mixed scrap has very different requirements to a large industrial recycling facility handling high volumes of ferrous and non-ferrous material every day. Output requirements determine not just the size of the hydraulic shear but also the duty cycle it needs to sustain.
It is worth thinking about your peak demand as well as your average. If your yard receives large deliveries of heavy scrap periodically, you need a scrap metal shear that can handle that surge without being pushed beyond its limits. A shear that is right sized for your average day may struggle when volumes spike.
It is also worth ensuring your equipment and site layout comply with your environmental permit conditions, which may include requirements around machinery placement and material handling.
What jaw opening do you need?
The jaw opening of a hydraulic shear determines the maximum section size it can accept. A machine with a jaw opening that is too small for your typical material will require pre-cutting or manual handling to reduce sections before they can be fed in, adding time, labour, and cost to your process.
When assessing jaw opening requirements, think about the longest and widest sections you regularly process, not just the most common ones. If demolition scrap or end-of-life structural steel is a regular part of your intake, you need a jaw opening that can accommodate those sections comfortably without additional preparation.
Does the size of your scrapyard affect which shear you choose?
Physical space is a practical constraint that is easy to overlook. Larger hydraulic shears require more floor space, higher clearance for loading, and adequate room for material infeed and outfeed.
Consider where the shear will sit in your yard layout and how material will flow to and from it. A machine that is technically the right size for your processing needs but does not fit comfortably in your available space will create operational problems that erode the efficiency gains it was supposed to deliver.
Fixed hydraulic shears are typically mounted in a permanent position and integrated into a processing line. If space is a genuine constraint, this may influence the size and type of scrap metal shear that is practical for your operation.
New vs. used hydraulic shears: which is right for your budget?
Once you have a clear picture of the size and capacity you need, the next question is whether to buy new or used. Both are viable options depending on your budget and operational requirements.
A new hydraulic shear gives you the latest hydraulic technology, a full manufacturer warranty, and the reassurance that the machine has not been subjected to previous wear. For operations where reliability and consistent performance are critical, new equipment can justify the higher price.
A quality used hydraulic shear, sourced from a reputable supplier, can offer excellent value. At JMC Recycling, all used scrap metal shears are inspected and serviced before sale to ensure they perform reliably. Used machines are subject to availability, so contact our team to find out what is currently in stock.
What ongoing support should you expect from your hydraulic shear supplier?
The size of the machine is only part of the decision. The support available for it matters just as much, particularly in a demanding scrapyard environment where downtime is costly.
When choosing a hydraulic shear for your scrapyard, consider the availability of spare parts, the accessibility of servicing support, and the track record of the supplier you are buying from. A machine that is the right size but difficult to get parts for can end up costing far more than a slightly more expensive machine with strong aftercare behind it.
At JMC Recycling, we offer comprehensive machine servicing and a wide range of spare parts for all the equipment we supply, helping you keep your hydraulic shear running at full capacity.
