A COMPLETE BUILDING APPROACH
Think beyond the frame.
The framing is one part of the building. Plan the envelope, finishes, jobsite handling and service life together.
Use materials deliberately
Coordinate framing and the envelope early, then compare the full project scope rather than a single material price.
Plan for recycling
Steel offcuts can be collected for recycling. Confirm local recovery options and document the waste plan with your contractor.
Coordinate the envelope
Thermal breaks, insulation, air sealing and moisture control are part of a complete steel building assembly.
Design for the location
Specify coatings, connections and assemblies for local exposure, loads and maintenance requirements.
IRONSIDE BY MODUSTEEL
PROGRAM IN DEVELOPMENTA nearshore vision.
A coordinated building system.
IRONSIDE is ModuSteel's proposed manufacturing program in Bonao, Dominican Republic. The plan brings light-gauge steel framing, standing-seam roofing, windows and doors, and project kitting into a coordinated production and delivery workflow.
For developers: villas, repeatable homes, ADUs and workforce housing.
For builders: framing packages, panelization and coordinated shell components.
For project teams: BIM coordination, quality checks and logistics planned around the job.
Manufacturing illustration. The Bonao facility is proposed; production capacity and free-zone status depend on development and approvals.
