On Site Welding are bespoke metal fabrications built by The Grate Guys to the exact drawing, load, and site. The Grate Guys treats each Hamilton on site welding job as its own scope — the site, the load, and the finish, assessed first and completed on site.

What drives on site welding in Hamilton (City of Hamilton) is primary steel production, steel fabrication and metal processing, heavy manufacturing, advanced manufacturing, port and logistics, healthcare and life sciences. The work concentrates around Bayfront industrial sector (Stelco/ArcelorMittal Dofasco lands), Hamilton Port / Pier 25 lands, Glanbrook Business Park, Red Hill Business Park, Ancaster Business Park. Much of the demand tracks Hamilton's industrial corridors near operations like ArcelorMittal Dofasco, Stelco, Port of Hamilton tenants, National Steel Car (rail cars), Hamilton Health Sciences and McMaster, numerous metal-processing and machine shops — heavy commercial and institutional sites, no two with the same spec.
Because Hamilton spans primary steel production, steel fabrication and metal processing, heavy manufacturing, advanced manufacturing, port and logistics, healthcare and life sciences, on site welding is never one-size: The Grate Guys fits the method to the building type, age, and use on every job.
As Canada's steel capital, Hamilton hosts ArcelorMittal Dofasco and Stelco on the bayfront plus National Steel Car building rail cars, supported by hundreds of fabrication and machine shops; corrosive harbour air and aging mills create constant demand for galvanized platforms, handrails and structural repair. Each Hamilton job is scoped around exactly those conditions, so nothing about the building or the neighbourhood is treated as a generic case.
What shapes a Hamilton job is deep local steel supply chain lowers material lead times, heavy-industrial corrosion environment near the bay favours hot-dip galvanizing, aging mid-century plants drive structural-steel repair and platform retrofits. The Grate Guys sets the gauge, material, and finish for those exact conditions on every Hamilton job, working to the measured opening rather than a regional default.
