What We Do

  • Abrasive / grit blasting of steel beams & columns

  • Surface preparation to SA2 / SA2.5

  • Remedial blasting following failed QA / NCRs

  • Internal columns, restricted access areas

  • Weekend & night working to suit programme constraints

All works are carried out with full RAMS, containment and clean‑down procedures suitable for occupied or live environments.

Specialists in Intumescent Preparation

We understand the requirements of intumescent coating systems and the importance of achieving the correct surface profile and cleanliness for successful application.

Our teams regularly work alongside:

  • Intumescent / passive fire protection contractors

  • Steelwork contractors

  • Principal contractors on commercial developments

We prepare steel correctly first time, reducing the risk of coating failure, delays or repeat NCRs.

Technical Capability

  • Surface preparation to ISO 8501‑1 SA2 / SA2.5

  • Elcometer surface profile testing

  • QA records & inspection documentation

  • Compatibility with major intumescent systems

  • CSCS‑certified operatives

  • Fully insured & site‑ready

QA documentation can be provided to support ITPs, fire engineer inspections and coating approvals.

Typical Scenarios We Support

  • Steel delivered late and needs urgent prep

  • Intumescent applicator cannot proceed due to surface condition

  • NCRs issued following inspection

  • Internal or awkward steel sections missed initially

  • Programme recovery requiring night or weekend works

If the steel needs prepping quickly and correctly, we can help.
