âš¡ Direct Answer: What Are Construction Equipment Sheet Metal Guards?
Construction equipment sheet metal guards are heavy-duty protective structural fabrications—including excavator engine hoods, radiator side cowlings, hydraulic cylinder rock shields, and heavy pump mounting brackets. Fabricated from 3.0mm to 8.0mm high-strength structural steel (Q355B, S355JR, or Hardox), they feature full-penetration robotic MIG welds, automated SA 2.5 steel grit blasting, and heavy-build anti-corrosive polyurethane coating capable of withstanding rock impacts and severe quarry environments.
Heavy-Duty Construction Metal Fabrication Standards
| Component Category | Structural Steel Grade | Manufacturing Process Standard |
|---|---|---|
| Engine Hoods & Cowlings | 2.5mm – 4.0mm Q355B / Strenx | Multi-radius bump bending on 300-ton press brake with acoustic damping insulation tabs. |
| Hydraulic Cylinder Guards | 5.0mm – 8.0mm Hardox 450 / Wear Steel | High-energy fiber laser cutting with chamfered weld prep; resists boulder impacts. |
| Pump Mounting Sub-Frames | 6.0mm – 12.0mm Heavy Structural Plate | Full robotic MIG welding on 3D Demmeler fixtures; stress-relieved and post-machined pads. |

Frequently Asked Questions on Heavy Guards
How do you prevent paint chips and rust on heavy construction equipment guards?
We shot-blast all welded structures to ISO 8501-1 SA 2.5 to strip mill scale, apply a 60 μm zinc-rich epoxy primer, and topcoat with a high-build polyurethane enamel providing superior stone-chip impact resistance.
