STRUCTURAL STEEL
FABRICATION

JCSI provides structural steel fabrication for demanding commercial, industrial, utility, and infrastructure projects. Project-specific structural and miscellaneous steel packages coordinated from approved drawings through fabrication and delivery.

VISION
FABRICATION
THE COMPLETE STEEL PROCESS

FROM VISION
TO VERTICAL

Connecting the vision behind the structure with the realities of building it.

FIELD INTELLIGENCE
VERTICAL
FABRICATION BUILT AROUND THE PROJECT

ONE FABRICATION PLAN.
MULTIPLE WAYS TO BUILD IT.

Fabrication decisions begin with the structure, the site, and the realities of installation. Scroll through the fabrication capabilities JCSI coordinates across offsite, field, and hybrid project environments.

FABRICATION STORY 04 Integrated Structural & Envelope Systems
01 — STRUCTURAL SYSTEMS

Structural Steel & Building Systems

Primary structural framing and building-system components coordinated around the approved project information, fabrication requirements, transportation plan, and final installation.

  • Beams, columns, trusses and joists
  • Bracing, frames and connection assemblies
  • Mezzanines and supporting structural components
  • PEMB and integrated building systems

02 — ACCESS & SUPPORT

Miscellaneous Metals, Stairs & Access

Project-specific fabricated components that connect structural systems with the practical requirements of access, support, protection, and movement through the completed building.

  • Steel stairs, handrails and guardrails
  • Ladders, platforms and gates
  • Lintels, embeds and equipment supports
  • Angles, frames and specialty miscellaneous metals

03 — LIGHT-GAUGE SYSTEMS

Light-Gauge & Cold-Formed Steel

Framing systems fabricated and assembled around actual building geometry, openings, transitions, and the conditions encountered within new construction and existing structures.

  • Exterior and interior wall framing
  • Headers, jambs and framed openings
  • Transitions and building-envelope support
  • Field-built project-specific assemblies

04 — INTEGRATED SYSTEMS

Integrated Structural & Envelope Systems

The Fall River Water Department project shows how primary steel, secondary framing, field installation, and exterior-envelope work advance as one coordinated construction sequence.

  • Primary structural-steel erection
  • Secondary and light-gauge framing systems
  • Field installation and system integration
  • Exterior-envelope framing and cladding progress
