What Is Joist Reinforcement?
Joist reinforcement involves strengthening or modifying an existing structural joist when the original member requires additional capacity or changes are needed for an approved building modification. The process may involve adding engineered reinforcement components, structural steel members, plates, angles, or other specified materials to an existing joist system.
Joist reinforcement is commonly associated with:
- Additional loading requirements
- Commercial building upgrades
- Rooftop equipment installations
- Mechanical retrofits
- Industrial facility modifications
- Changes to existing structural configurations
Because structural joists vary in design, size, configuration, and capacity, reinforcement work must be completed according to the applicable project drawings and engineering specifications. Our role is to provide professional field welding, fabrication, and installation support for the approved reinforcement scope.

Every project has different structural requirements. Minhas Mobile Welding works from the project information, drawings, and specifications provided by the contractor or project team.
OWSJ Reinforcement and Open Web Steel Joist Modifications
OWSJ, or Open Web Steel Joist, is a widely used structural system in commercial and industrial buildings.
Open Web Steel Joists are commonly found in:
- Warehouses
- Manufacturing facilities
- Distribution centres
- Commercial buildings
- Retail properties
- Schools and institutional buildings
- Industrial facilities
- Large-span roof structures
An OWSJ system uses an open web configuration that can provide efficient support across longer spans while allowing space for mechanical, electrical, and building services.
When additional loads or modifications are introduced, an existing Open Web Steel Joist may require evaluation and project-specific reinforcement.
Minhas Mobile Welding provides field welding support for OWSJ reinforcement projects based on approved engineering drawings and specifications.
When Is OWSJ Reinforcement Required?
Open Web Steel Joist reinforcement may be considered when changes to a building introduce new loads or alter the original structural conditions.
Common project situations include:
New Rooftop HVAC Units
A replacement HVAC unit may be heavier or positioned differently than the original equipment.
The project may require structural modifications or reinforcement based on the new equipment load and approved engineering design.
Rooftop Units and RTUs
Commercial rooftop units can introduce concentrated loads at specific locations.
When existing joists were not originally designed for the revised conditions, reinforcement details may be required as part of the project.
Mechanical Equipment Upgrades
New exhaust systems, ventilation equipment, mechanical units, and other building systems can change the loading requirements of an existing structure.
Additional Roof Loads
Changes to roofing systems, equipment, suspended components, or other additions may introduce loads that were not included in the original structural design.
Solar Equipment and Building Upgrades
Solar installations and other rooftop improvements may require a review of the existing structural system before installation.
New Openings for Building Services
Commercial renovations may require openings or modifications for:
- Ductwork
- Mechanical systems
- Ventilation
- Flues
- Building services
Structural modifications should follow the project’s approved engineering requirements.
Joist Girder Reinforcement
Joist Girders are structural members designed to support other joists and transfer loads to supporting columns or structural framing.
Because Joist Girders play a significant role in the overall structural system, modifications and reinforcement require careful project-specific planning.
Minhas Mobile Welding can provide field welding and fabrication support for approved Joist Girder reinforcement or modification projects.
Depending on the project requirements, our team can assist with:
- On-site structural welding
