Rope access NDT and surface inspection services

Professional Non-Destructive Testing Services

NDT is essential for detecting internal and surface-level defects in steel without damaging the structure. Our technicians use advanced tools and proven methods to identify cracks, corrosion, and weld flaws—before they become critical failures.

Our NDT techniques include:

  • Ultrasonic Testing (UT) for internal flaws

  • Magnetic Particle Testing (MT) for weld inspections

  • Penetrant Testing (PT) for surface cracks

  • Visual Testing (VT) by qualified inspectors

  • Borescope/endoscopic inspection in confined spaces

These inspections are critical for preventive maintenance, regulatory compliance, and asset life extension.

Steel Surface Coating Inspection Services

A coating is only as good as its application—and its condition over time. Gridinta performs detailed surface coating inspections to ensure your protective layers are intact, consistent, and within specification.

Steel surface coating inspection includes:

  • Coating thickness measurements

  • Adhesion and integrity testing

  • Surface preparation assessment

  • Corrosion mapping and analysis

  • Offshore and marine environment inspection

We help you verify steel coating performance and identify early signs of deterioration before damage occurs.

Choosing the Inspection Scope and Deliverables

The inspection method should follow the material, component geometry, suspected discontinuity and access available—not a generic test list. Gridinta's existing capabilities include visual testing, penetrant testing, magnetic-particle testing, ultrasonic testing and thickness measurement, together with steel-surface and coating checks. The final method or combination is agreed for the asset and inspection objective.

Reporting can be tailored to the project and may include inspected areas, method used, marked defect locations, readings, photographs and a summary of findings. The applicable procedure, acceptance criteria, reporting format and responsibility for engineering disposition should be confirmed before work starts.

For a quotation, share the asset type and location, material and dimensions, drawings or weld maps, inspection area and quantity, suspected damage, previous reports, required method, acceptance criteria, access conditions and preferred schedule. Surface condition, coating removal, temperature, geometry, isolations and safe access can limit method suitability or productivity.

Inspection can support onshore wind maintenance, offshore wind maintenance, industrial welding and fitting and rope access projects.

NDT and Steel Surface Coating Inspection: FAQ

What NDT and coating inspection services does Gridinta provide?
Gridinta provides non-destructive testing and steel surface coating inspection services for industrial structures where condition assessment must be carried out safely and accurately. The scope can include defect detection, coating checks, corrosion assessment, and inspection at height using rope access methods where needed.
What is non-destructive testing used for?
NDT is used to identify internal and surface-level defects without damaging the structure being inspected. It helps detect issues such as cracks, corrosion, weld flaws, and other early signs of deterioration before they develop into larger failures.
Which NDT methods can Gridinta support?
Depending on the scope, Gridinta can support methods such as Ultrasonic Testing (UT), Magnetic Particle Testing (MT), Penetrant Testing (PT), Visual Testing (VT), and borescope or endoscopic inspection in confined or hard-to-reach areas. The right method depends on the material, defect type, and inspection objective.
What does steel surface coating inspection include?
Steel surface coating inspection focuses on checking whether protective coatings are intact, consistent, and performing as intended. This can include coating thickness measurements, adhesion and integrity checks, surface preparation assessment, corrosion mapping, and environment-specific inspection where relevant.
Why is coating inspection important for steel structures?
Coatings protect steel against corrosion and environmental damage, but they degrade over time. Regular coating inspection helps identify weak points early, confirm whether the coating system is still performing, and support timely maintenance before structural damage develops.
Can you perform NDT and coating inspections at height?
Yes. Gridinta can perform these inspections at height using rope access where it is the most practical and controlled method. This helps reach difficult locations efficiently without unnecessary scaffolding or extended shutdown requirements.
Do you inspect both onshore and offshore structures?
Yes. Gridinta supports both onshore and offshore inspection work. The inspection approach is adapted to the structure, access conditions, environmental exposure, and the client’s maintenance or compliance requirements.
Can NDT help prevent failures and unplanned downtime?
Yes. NDT is widely used to identify hidden defects before they become critical. Early detection helps operators plan repairs, reduce risk, support compliance, and avoid unexpected downtime caused by undetected structural or weld-related problems.
Do you provide reports after inspections?
Yes. Inspection work is typically documented to support maintenance planning, compliance, and follow-up actions. Depending on the scope, reports may include findings, measurements, photo evidence, and recommendations for next steps.
How do we request an NDT or coating inspection quote?
Send your structure type, site location, inspection scope, target dates, and any known access restrictions or technical requirements. If you already have previous reports, drawings, or condition history, including them will help define the scope faster.
