Common grades
- Hardox 400 — balanced hardness and weldability for rock and gravel.
- Hardox 450 — higher abrasion resistance for granite, basalt and iron ore.
- S355 structural plate — appropriate for GP buckets in non-abrasive soils only.
Fabrication quality
Heat-affected zones beside welds soften with poor WPS/PQR control. Floor plate should thicken toward the heel where load concentrates.
Importer verification
Request mill test certificates matching heat numbers. Third-party hardness testing on delivery catches AR plate substitution. Weight vs spec detects thin-floor lightweight buckets.
