Steel Cutting Services in Hamilton, ON

Steel cutting is one of the jobs CDS is called for most across Hamilton and all of Ontario, and it rarely arrives on its own. When a beam, column, plate, or a curtain of heavy rebar has to come out, our diamond blades and diamond wire cut through it cleanly — usually on the same job where we are already sawing concrete. Family-run since 1967, we have been cutting steel for as long as we have been cutting concrete.

What Steel Cutting Is

Steel cutting uses diamond-segmented blades and diamond wire to slice through structural and embedded metal without torch heat or heavy percussion. Where another contractor might reach for a cutting torch or a jackhammer, we make a precise, controlled cut that leaves the surrounding structure intact. That matters most when the steel is buried in concrete, sits next to finishes or live equipment, or has to be taken out in a specific sequence.

Our crews cut a lot of steel. In a typical week that includes:

• Structural steel — beams, columns, channels, and angle
• Heavy rebar and welded mesh embedded in slabs, walls, and footings
• Steel plate, embed plates, and base plates
• Dowels, anchors, and tie-ins left behind by earlier work
• Pipe, casing, and miscellaneous metal caught inside a cut line

How CDS Cuts Steel

Every job starts the same way it does for concrete: we scan before we cut. GPR and other locating tools tell us where the reinforcement, conduit, and embeds sit, so the blade meets steel on our terms rather than by surprise. Our diamond blades are workhorses — a properly specified blade will track through rebar and structural steel all day, and we match the blade or the wire to the metal, its thickness, and the space we have to work in.

For the heaviest sections — thick plate, bundled bar, or a steel-and-concrete composite member — we switch to diamond wire. Wire cuts have no practical depth limit and reach into places a blade cannot, which is why steel cutting and our diamond wire sawing service so often go together. The wire creates the opening or frees the section; it does not weld, fabricate, or replace anything — removal and demolition crews take it from there.

Equipment That Makes the Cut

The right tool depends on what the steel is doing and where it lives.

Diamond blades

Segmented diamond blades on hand saws, wall saws, and slab saws handle the majority of our steel cutting — rebar in a slab, embeds in a wall, plate on a landing. They are fast, accurate, and leave a square edge with no heat-affected zone in the surrounding metal.

Diamond wire

For oversized, heavily reinforced, or awkwardly placed steel, a diamond wire loop pulls through the section from almost any angle. It is how we take down composite columns and thick plate that a blade simply cannot reach.

The electric option for occupied buildings

When steel has to be cut inside a running plant, a hospital, a warehouse, or a tenanted building, we run electric-driven wire and blade equipment. Electric tools produce low emissions and less noise and dust than engine-driven or torch-based methods, so the cut is safe for occupied spaces and easier on everyone nearby. It is a small ESG advantage on the metal side of the work, and a large practical one when you cannot shut the building down.

Steel and Concrete on the Same Job

Most reinforced concrete is really a steel-and-concrete sandwich, so nearly every cut we make goes through both. That is the heart of our concrete cutting services — a saw line through a loaded slab or wall hits bar, mesh, and embeds as a matter of course, and the blade has to be ready for it. Treating steel as an afterthought is how other contractors end up with stalled cuts and torn edges. We plan for the metal from the first pass.

When the goal is to take a structure apart rather than just open it, steel cutting feeds directly into concrete demolition and concrete removal. We size and free members into pieces the removal crew can lift and haul, which keeps the site controlled and the demolition sequence predictable.

Typical Steel Cutting Jobs and Clients

Steel cutting shows up across industrial, commercial, and institutional work:

• Demolition and retrofit — cutting beams, columns, and embedded steel to open or dismantle a structure
• Industrial plants — trimming equipment bases, embed plates, and anchor bolts during line changes and relocations
• Structural modifications — creating openings through reinforced walls and floors for new stairs, shafts, or services
• General contractors and demolition firms — removing rebar and steel a torch cannot safely reach near finishes or flammables
• Municipal and infrastructure work — cutting reinforced sections on tanks, structures, and heavy civil elements

Why Contractors Call CDS for Steel Cutting

Cutting steel is routine here, not a special request. Contractors keep coming back because:

• Family-run since 1967 — the longest-running concrete and steel cutting company in Ontario
• $5 million liability insurance and full WSIB compliance — the paperwork is ready before we arrive on site
• Scan-before-cut as standard — no guessing where the steel, rebar, and services are
• Self-contained crews — our own saws, wire rigs, power, and water and slurry management
• Diamond blades that are genuine workhorses — steel is part of nearly every cut we make

Serving Hamilton and All of Ontario

Our shop is at 276 Ferrie St E in Hamilton, L8L 3T7, and our crews travel across the province from there. Whether the steel is in a Hamilton warehouse, a Toronto retrofit, or an industrial plant anywhere in Ontario, CDS mobilizes with the right blades, wire, and power to make the cut — cleanly, safely, and on schedule.

Frequently Asked Questions

Can CDS really cut structural steel and rebar, or just concrete?

Both, and usually together. Diamond blades and diamond wire cut structural steel, plate, beams, columns, and heavy rebar, and most of our concrete cutting goes straight through embedded steel anyway. Cutting steel is a routine, everyday part of what we do.

How is diamond steel cutting different from torch cutting?

A cutting torch uses heat and throws sparks and slag; a diamond blade or wire makes a cold, controlled mechanical cut. That means no open flame near finishes, insulation, or flammable materials, a cleaner edge, and no heat-affected zone in the surrounding steel — a real advantage inside occupied or sensitive buildings.

Can you cut steel inside an occupied building?

Yes. We run electric-driven blade and wire equipment for indoor work, which keeps emissions, noise, and dust low enough to cut in a live plant, warehouse, or tenanted space without shutting it down. We manage water and slurry so the work area stays clean and controlled.

What is the thickest steel you can cut?

With diamond wire there is no practical depth limit — we routinely cut thick plate, bundled rebar, and composite steel-and-concrete members that a blade cannot reach. For most beams, columns, and embeds a diamond blade is faster, so we match the method to the section.

Do you remove the steel after you cut it?

We cut and free the steel into manageable pieces; hauling and disposal are handled through our concrete removal and demolition services or by your own site crew. Our wire and wall saws create the opening and cut sections for removal — they do not fabricate or install new steel.

Cutting concrete and steel safely means controlling silica dust; the OSHA respirable crystalline silica standard sets the exposure limits we work within.
