Heavy-duty machinery for producing durable frames, chassis components and wear parts for agricultural equipment and trailers.
Agricultural and trailer fabrication demands robust, repeatable processes for working with thick materials, large sections and structural assemblies. Whether you’re manufacturing trailer chassis, drawbars, agricultural attachments, Hardox wear parts or heavy brackets, you need machinery that can handle big sections, high loads and long production runs.
This page outlines the key challenges in agricultural and trailer manufacturing and the machinery best suited to improving productivity, accuracy and long-term reliability.

Challenges in Agricultural & Trailer Fabrication
Workshops in this sector typically face:
-
cutting thick plate, Hardox and other high-strength steels
-
processing large RHS/SHS, beams, angle and channel
-
handling long chassis rails, drawbars and frames
-
producing repeatable structural components at volume
-
drilling heavy plates and large fabrications accurately
-
forming heavy-gauge components with consistent bending
-
rolling large sheets for tanks, trailers and agricultural equipment
-
maintaining throughput whilst ensuring strong, reliable joints
Robust, high-capacity machinery is essential to keep production efficient and safe.
Materials & Profiles Commonly
Used in Agricultural & Trailer Manufacturing
Fabricators regularly work with:
-
mild steel and heavy-gauge plate
-
high-strength and wear-resistant steels (e.g. Hardox)
-
RHS/SHS box section and CHS tube
-
angle, channel and I-beam sections
-
flat bar and structural strip
-
sheet metal for guards, covers and side panels
-
components needing both structural strength and good fit-up
Your machinery must cope with both precise fabrication and large-scale structural work.
How Modern Machinery Supports Agricultural & Trailer Manufacturing
CNC Plasma Cutters
CNC plasma systems are a cornerstone of heavy fabrication, especially for:
-
thick plate cutting
-
Hardox and wear-plate components
-
digger bucket profiles and wear strips
-
heavy brackets and reinforcement plates
-
agricultural implement parts
They offer fast, cost-effective cutting of heavy and wear-resistant steels where high strength is essential.
Flatbed Fibre Lasers
Flatbed lasers are ideal for:
-
brackets and mounting plates
-
gussets and stiffeners
-
hitch plates and coupling components
-
guards, covers and panel work
They deliver accurate, clean edges that improve weld fit-up and reduce rework.
Tube & Section Lasers
Tube and section lasers are ideal for cutting:
-
chassis rails and cross members
-
box-section frames
-
structural supports and linkages
-
precisely mitred drawbar components
-
cut-outs and slots in RHS/SHS and CHS
They deliver clean, accurate cuts on RHS, SHS, CHS, angle and channel, reducing manual prep and improving assembly speed.
Press Brakes
Press brakes, especially high tonnage models are used extensively to form:
-
structural brackets
-
hinge and mounting plates
-
folded sections for frames
-
reinforcement pieces
-
folded components for trailer bodies and agricultural attachments
CNC press brakes provide repeatable, accurate bending on heavy and medium plate.
Tube Benders
Tube benders support the fabrication of:
-
curved drawbar and frame elements
-
protective hoops and guards
-
hydraulic and mechanical linkage tubes
-
custom tubular components for agricultural machines
They provide consistent, low-distortion bends across various tube sizes.
Sheet Rolls
Large capacity sheet rolls are crucial for:
-
rolling heavy plate into cylinders or cones
-
slurry tank sections
-
trailer sides and curved bodies
-
agricultural tankers and hoppers
-
structural rolled shells and heavy covers
They deliver controlled forming of large-diameter, thick material components.
Lathes
Lathes are used to produce:
-
bushings and spacers
-
pins and shafts
-
axle components
-
turned fittings for hinges and couplings
Turned parts are critical in pivot points, linkages and running gear.
Mills
Milling machines support:
-
machined faces and mounting surfaces
-
precision slots and pockets
-
custom brackets and fixtures
-
machined details on plates and blocks
They ensure accurate fit between fabricated and machined components.
Bandsaws
Bandsaws provide reliable cutting for:
-
beams, box section, angle and channel
-
solid bar and billets for machined components
-
preparing stock for welding or machining
-
cutting material to length efficiently
They are essential for handling heavy structural profiles and feedstock.
Pillar Drills
Pillar drills are ideal for:
-
drilling bracket holes
-
preparing mounting points
-
tapping and countersinking
-
repetitive drilling on plates and components
A dependable machine for repeat hole-making in heavy and medium sections.
Radial Arm Drills
Radial arm drills are especially valuable for:
-
drilling large or heavy plates that are difficult to move
-
drilling into large frames, beams or assemblies
-
accurately spacing holes across bigger components
-
working on awkward or oversized fabrications
The extended reach allows drilling operations across a broad area without constant repositioning.
Steelworkers
Steelworkers provide fast, versatile processing for:
-
punching accurate holes and slots in flat bar, angle and plate
-
shearing and cropping bar, box section and angle
-
notching plate and section materials
-
preparing components for welding or bolted assembly
They combine multiple fabrication functions into one compact, efficient machine, making them invaluable for workshops handling repetitive structural tasks and varied everyday fabrication work.
