Welding Expertise Backed by Fire Protection Knowledge

Most welding contractors don't understand fire codes. Most fire protection contractors subcontract their welding. Delta does both in-house.

AWS

American Welding Society Certified

Our welders hold AWS certifications covering structural, pipe, and specialty welding applications. Certifications are current and documented for every project.

NFPA 13

Fire Sprinkler Pipe Welding Standard

NFPA 13 governs welded pipe connections in fire sprinkler systems. Delta's welders know these requirements directly — not from a manual, but from years of fire protection project experience.

AWS D1.1

Structural Welding Code

All structural steel welding follows AWS D1.1 — the standard for welded steel construction. Required for commercial building permits and structural inspections.

30+ Yrs

Fire Protection Industry Experience

Delta has been serving California commercial properties since 1990. That experience means our welding work is integrated with a deep understanding of fire protection requirements.

The Single-Vendor Advantage

When welding and fire protection come from the same contractor, you get faster projects, fewer coordination gaps, and a single point of accountability:

  • Fire sprinkler pipe welding and system installation on the same ticket
  • Security gate fabrication coordinated with access control installation
  • Iron works and fire escape compliance handled together
  • No markup on subcontracted welding — we do it ourselves
  • One licensed, insured contractor for the entire project scope
