Quarrying
Reliable steel for continuous extraction and crushing
Quarrying operations are defined by constant impact, abrasion, and heavy loads — from raw rock extraction to crushing, transport, and stockpiling. Equipment is exposed to intense wear, and any weakness leads to stoppages, repair costs, and productivity losses.
QUARD is built for this environment.
Its high hardness, excellent wear resistance, and dimensional versatility make it the material of choice for manufacturers of quarry machinery who need equipment that runs longer and requires less maintenance — even in the most abrasive conditions.
Why QUARD is the smart choice for quarrying equipment
QUARD helps quarrying professionals keep machines running — not in the workshop, but on site where they belong.
- Excellent wear resistance for high-friction materials
- Lighter structures that improve handling and reduce operating costs
- Reliable forming and welding for efficient assembly and repair
- Available in a full range of dimensions with precision rolling options
From extraction to crushing, QUARD delivers consistent performance under pressure — day after day.
Abrasive conditions demand a high-performance steel
Whether in limestone, granite, or basalt quarries, machine components are under constant attack from hard and sharp materials. QUARD provides the resistance needed for:
- Dump truck bodies and linings
- Hopper walls and feeder zones
- Jaw crusher liners and impact plates
- Conveyor chutes, loading buckets, and screen decks
Compared to traditional steels, QUARD allows:
- Longer service life, even under repeated impact
- Reduced weight, making equipment easier to handle and more fuel-efficient
- Lower maintenance frequency, with better reliability over time
Its workability also helps simplify processing in workshops, offering efficient welding, cutting, and bending even in high-thickness formats.
Design freedom with QUARD’s dimensional range
QUARD is available in a broad dimensional range to support robust quarry applications:
- Thickness: from 3.2 mm to 64 mm
- Hardness: up to 550 HB
- Suited for: static and mobile wear parts, protective linings, high-impact components
Thanks to wide plate widths up to 3,100 mm, manufacturers can reduce the number of welded seams, simplify assembly, and optimize nesting strategies — saving time and material.
Precision that pays off — with InThinity
In quarry equipment, plate consistency improves both fabrication and performance. With InThinity, QUARD and QUEND plates under 15 mm thickness come with:
- Tighter thickness tolerances than EN 10029
- Superior flatness, even in thicker gauges
- Reliable behavior in bending and forming
These properties reduce adjustment time in the workshop and allow users to exploit the full mechanical potential of QUARD in each component — from liner to frame.
Other applications
QUARD and QUEND prove their value well beyond quarrying, serving a wide spectrum of industries such as:
