ISO 3834-2:2021 CERTIFIED

CERTIFIED INTEGRITY

Structure is everything. We hold the ISO 3834-2:2021 certification from TÜV Rheinland for comprehensive quality requirements in fusion welding. This ensures every bucket, grapple, and coupler meets rigorous international standards for structural safety and load-bearing consistency.

GENUINE SSAB STEEL

Hardox Wear Plate

We use Hardox 450 and 500 for high-wear zones. As a member of the Hardox In My Body program, we guarantee genuine material with superior abrasion resistance.

Strenx Performance Steel

Strenx 700 and 900 structural steel allows us to reduce attachment weight while increasing lifting capacity and fuel efficiency.

Digital Traceability

From the steel mill to your site. We maintain full material traceability with Material Test Certificates (MTC 3.1) available for every serial number.

ENGINEERED FOR UPTIME

1

Design & Simulation

Every prototype undergoes Finite Element Method (FEM) analysis to identify stress points before a single sheet of steel is cut.

2

Precision Cutting

CNC laser and plasma cutting ensures tight tolerances, ensuring perfect joint fit-up for superior weld penetration.

3

Certified Welding

Welders qualified to ISO 9606 perform fusion welding under the supervision of our ISO 3834-2 responsible welding coordinators.

4

Finishing

Industrial shot blasting and premium coating systems protect your investment from corrosion in harsh field conditions.

RIGOROUS VERIFICATION

  • Ultrasonic Testing (UT) of critical full-penetration welds
  • Magnetic Particle Inspection (MPI) for surface cracks
  • 100% Dimensional Check of mounting points
  • Hardness testing to verify heat-affected zones (HAZ)
