Heavy Scrap Recycling Solutions: Define the Processing Route by Size and Form

On this page, heavy scrap mainly refers to scrap metal that is oversized, excessively long, large in cross-section, thick in structure, heavy as an individual piece, or irregular in shape, making it difficult to transfer, feed into equipment, or prepare as furnace charge.

Here, “heavy” describes the condition of the scrap in terms of size, cross-section, individual-piece structure, and processing difficulty. It does not refer to a single fixed steel scrap trade grade. Heavy steel scrap is one typical case, but it should not be directly equated with specific international scrap grades such as HMS.

Heavy Scrap Recycling Solutions: Define the Processing Route by Size and Form

The main problem with this type of scrap is usually not low bulk density. More often, its original length, cross-sectional dimensions, or overall form does not meet the requirements for transport, equipment feeding, or the next process.

For this reason, heavy scrap processing is not about making the material as small as possible. The first step is to answer two questions:

What exactly makes the current scrap unsuitable for the next process?
Which dimensional factor needs to be changed, and to what extent?

If the material already meets transport and downstream requirements, there is no need to add unnecessary mechanical processing. If its length, cross-section, or overall dimensions are unsuitable, the next step is to determine—based on material, form, and target size—whether it can be sheared directly or requires pretreatment first.

TITAN evaluates the material, length, cross-sectional shape and dimensions, individual-piece structure and weight, throughput, and downstream requirements to determine whether the scrap is suitable for direct mechanical shearing and to discuss the corresponding size-adjustment route.

What to Confirm for Different Heavy Scrap Conditions

Identify the Dimensional Factor Limiting the Next Process

Heavy scrap is not a single material with a fixed set of dimensions. Two pieces of scrap that both appear large may face completely different processing problems because of differences in length, cross-section, or overall form.

Before defining the processing route, confirm the material, overall dimensions, cross-sectional shape and dimensions, individual-piece structure, and the material specifications accepted by the next process.

Long Heavy Scrap

Long sections, tubes, beams, and other elongated structural pieces may not have an especially large cross-section, but their length can affect handling within the yard, vehicle loading, or feeding into downstream equipment.

The first issue is whether the material is too long for the next stage. Processing decisions should not be based on individual piece weight alone.

Scrap material
Original length
Cross-sectional shape and dimensions
Whether individual pieces are bent, bundled, or otherwise irregular
Target length permitted for transport or the next process

Heavy Scrap with Large Cross-Sections, Thick Walls, or Solid Sections

Some scrap may not be particularly long but may have a large diameter, side length, wall thickness, or overall cross-section.

Two pieces of similar length can require very different processing conditions if their cross-sectional structure and dimensions differ.

For this reason, suitability for a particular mechanical shearing method cannot be determined by length or weight alone.

Scrap material
Whether the section is solid or hollow
Cross-sectional shape
Actual diameter, side length, width, thickness, or other cross-sectional dimensions
Material specifications accepted by the next process

Oversized or Irregular Heavy Scrap

Large structural components, dismantled industrial metal parts, and other irregular heavy scrap may be limited primarily by their overall form rather than by a single length or cross-sectional dimension.

These materials may combine large overall dimensions, multiple protruding sections, or a feeding orientation that is difficult to control.

For this type of scrap, the first question is whether it can enter the downstream size-adjustment stage directly.

If the original structure exceeds the allowable feeding or processing range of the equipment, dismantling, pre-cutting, or other necessary pretreatment may be required first.

Maximum overall dimensions
Individual-piece structure and shape
Whether protruding sections interfere with feeding
Whether the material can be handled safely and fed into the process stably
Target condition required by the next process

Heavy Scrap That Already Meets Transport or Downstream Requirements

Not every large or heavy piece of scrap needs further size reduction.

If the material can already be handled and transported safely, and its current dimensions meet the requirements of downstream equipment, furnace-charge preparation, or other recycling stages, it can proceed directly to the next process.

Further processing should depend on whether the current dimensions actually create a transport, feeding, or downstream-use problem—not simply on the fact that the material is classified as heavy scrap.

Check actual need

Different Heavy Scrap Conditions Require Different Processing Routes

Define the Target Size First, Then Determine Whether Direct Shearing Is Feasible

The purpose of heavy scrap processing is not to produce a single standard size for every material. It is to resolve the dimensional factor that actually prevents efficient transport, feeding, or furnace-charge preparation.

Shearing can reduce long, large, or heavy scrap to dimensions better suited to downstream operations, but whether a particular material can be sheared directly still depends on its material, cross-section, and overall structure.

Long Heavy Scrap: Reduce Length to the Required Target Within the Applicable Range

If the main issue with long sections, tubes, beams, or other elongated scrap is excessive length, and the material, cross-section, and overall condition are suitable for mechanical shearing, the scrap can be shortened to the required length.

The target length should be determined by transport, feeding, or furnace-charge requirements—not by an objective of producing the shortest possible scrap.

Heavy Scrap with Large Cross-Sections, Thick Walls, or Solid Sections: Confirm Whether It Falls Within the Processing Range

For heavy scrap with large cross-sections, thick walls, or solid sections, first determine whether the material falls within the processing range of the relevant equipment based on its material, cross-sectional shape, and actual cross-sectional dimensions.

If the material is suitable for direct mechanical shearing, it can be processed to the required target size.

If the cross-section, material, or overall structure exceeds the allowable feeding or shearing range of the equipment, direct processing should not be assumed. Appropriate pretreatment or another size-reduction method should be considered first.

→ Confirm material, cross-sectional shape, and dimensions

→ Within the direct processing range: shear to the target size

→ Outside the direct processing range: use appropriate pretreatment or another size-reduction method

Specific equipment size and model selection should only be confirmed after the processing route has been defined and actual material data are available.

Oversized or Irregular Heavy Scrap: First Determine Whether It Can Enter the Process Safely and Stably

For large structural components or complex-shaped heavy scrap, the limiting factor may not be a single cross-section. The overall geometry may prevent the material from entering the equipment directly.

If protruding structures, overall dimensions, or shape interfere with handling and feeding, first determine whether dismantling, pre-cutting, or other pretreatment is required.

The purpose of pretreatment is to convert the original large scrap piece into a condition that can safely and stably enter the next processing stage. It is not intended to create an additional fixed process step.

Material Already Meeting Downstream Requirements: No Further Size Reduction Is Needed

Heavy scrap does not automatically require shearing.

If the current material can already be handled, transported, and fed into the next process normally, and its dimensions meet downstream requirements, there is no reason to continue processing simply to obtain “smaller scrap”.

Additional size reduction only makes sense when it solves an actual transport, feeding, or furnace-charge preparation problem.

Processing Principle

When defining a heavy scrap processing route, answer three questions first:

Which factor is currently creating the dimensional problem?

Length, cross-section, or overall form?

What size does the next process actually require?

Can the current material be processed directly within the allowable equipment range?

Once these conditions are clear, the route can be defined as direct mechanical shearing, necessary pretreatment followed by size adjustment, or no additional processing.

Heavy Scrap Processing Before Downstream Recycling

From Original Heavy Scrap to the Size Required by the Next Process

The processing route should be built around the target size rather than assuming that every heavy scrap stream must pass through the same equipment.

Decision 01Does the current condition already meet the requirements?

Yes

Decision 02Is the material suitable for direct mechanical shearing?

Suitable

Shear to the required size

Not suitable for direct processing

Necessary dismantling, pre-cutting, or other pretreatment

Reassess the downstream size-adjustment method

Transfer, further processing, furnace-charge preparation, or other recycling stages

Not every heavy scrap project requires all of these steps, and equipment combinations such as shearing → shredding → baling should not be treated as a fixed process route.

TITAN is mainly involved in the size-reduction stage where heavy scrap is suitable for mechanical shearing. Oversized structures beyond the applicable equipment range, specialised dismantling and cutting, and downstream melting should be handled according to the actual project requirements.

FAQ

Are Heavy Scrap, Heavy Steel Scrap, and HMS the Same Thing?

No.

On this page, heavy scrap describes the processing condition of scrap metal in terms of size, length, cross-section, individual-piece structure, and overall form.

Heavy steel scrap further limits the concept to heavy scrap made of steel.

HMS (Heavy Melting Steel) belongs to a specific international steel scrap trading grade system with its own classification and trading requirements.

A batch of scrap should therefore not be called HMS simply because it is large or requires shearing.

Can Direct Shearing Be Determined by Individual Piece Weight Alone?

No.

Individual piece weight does not fully represent the actual shearing conditions.

Material, original length, cross-sectional shape, cross-sectional dimensions, solid or hollow structure, maximum overall dimensions, and target size must also be considered.

Two pieces with the same weight can require completely different processing conditions if their cross-sections and structures differ.

Can Large Structural Components Be Fed Directly into a Scrap Metal Shear?

Not necessarily.

Large or irregular structural components may exceed the allowable equipment range because of their overall dimensions, protruding structures, cross-section, or feeding condition.

In such cases, first determine whether dismantling, pre-cutting, or other pretreatment is required before deciding whether mechanical shearing is suitable.

Suitability cannot be judged solely from the rated shearing force of the equipment.

Is Shorter Always Better When Shearing Heavy Scrap?

No.

The purpose of size adjustment is to make the material suitable for transport, equipment feeding, furnace-charge preparation, or another downstream process.

Once the target size meets downstream requirements, there is normally no reason to continue shearing the material into shorter pieces.

The target size should be defined first, followed by only the amount of size reduction actually required.

Must Heavy Scrap Be Shredded or Baled After Shearing?

Not necessarily.

Shearing, shredding, and baling solve different processing problems. There is no fixed requirement for them to be used sequentially.

If the sheared material already meets transport, feeding, or furnace-charge requirements, it can proceed directly to the next process.

Additional stages are only required when a clear downstream need remains for further size reduction, volume reduction, or another form of processing.
