Mobile welding & on-site fabrication
On-site welding and field fabrication services for commercial and industrial projects, supporting repairs, modifications, and structural work directly at your facility across Toronto and the GTA.

Mobile welding and on-site steel fabrication play a critical role in commercial and industrial projects across Ontario, where structures, equipment, and safety systems often require modification, repair, or integration on-site. These services allow structural steel work to be completed without dismantling existing installations or transporting oversized components, helping maintain project schedules and operational continuity.
On-site fabrication is commonly used for structural adjustments, equipment supports, safety railings, stairs, and custom steel elements that must align precisely with existing conditions. Certified mobile welding crews work in accordance with Ontario Building Code (OBC), OH&S regulations, and CSA standards, ensuring that all field-installed steel components meet safety, quality, and compliance requirements for commercial facilities.
Field services & on-site solutions
Mobile welding and on-site fabrication services focused on integrating, modifying, and repairing steel components directly within active commercial and industrial environments.
Field welding for adjustments, reinforcements, and alterations to existing steel structures without dismantling or relocation.
On-site fabrication and installation of custom supports, brackets, and connection plates to match real-world site conditions.
Mobile fabrication and welding of handrails, guardrails, and protective barriers where shop-fabricated systems are not feasible.
On-site welding for stair adjustments, landings, transitions, and access components integrated into existing structures.
Repair of cracked welds, damaged steel members, and load-bearing components identified during inspections or renovations.
Precision field fabrication to connect new steel elements to legacy structures, machinery, or building frameworks.
Materials & Styles
Materials and welding methods selected for on-site work must accommodate variable site conditions, access limitations, and integration with existing steel.
Material | On-Site Welding Method | Typical Field Applications |
|---|---|---|
Carbon Steel | Stick (SMAW), MIG | Structural modifications, equipment supports, and reinforcements |
Stainless Steel | TIG, MIG | Food-grade structures, handrails, and clean environments |
Aluminum | TIG, MIG | Lightweight frames, brackets, and access components |
Galvanized Steel | Stick (with prep) | Repairs to guards, railings, and exterior structures |
Mixed Materials | Process-specific | Integration with existing steel and machinery |
Key considerations
Mobile welding and on-site fabrication require careful coordination with engineering requirements and active job sites.
Field welds and connections must maintain original load paths and structural performance.
Work is performed in operational environments requiring controlled access, hot-work permits, and safety coordination.
All on-site welding aligns with Ontario Building Code (OBC), OH&S regulations, and applicable CSA standards.
Precision measurements and alignment are critical when integrating new steel into existing structures.
