Metal Fabrication in Hamilton

In-house laser cutting — coming in 2027

From flat plate to finished welded assembly under one roof — delivered on time across the GTA and Southwestern Ontario.

One shop, drawing to finished assembly

Since 1999, RUMIX has fabricated custom metal parts for manufacturers in Hamilton, Toronto and Southwestern Ontario. Cutting, forming, welding, machining and assembly all happen in the same building — so your parts don’t bounce between suppliers, which is where most delays and quality problems start.

One-off prototypes, replacement parts and repeat production. With 300+ material profiles in stock and a team that averages 18 years of experience, we can usually start the day your order is approved. New to fabrication? Read how steel fabrication works — from drawing to finished part.

What we fabricate

Parts, weldments and assemblies

Cut parts & blanks

Profiles, gussets, brackets, base plates and flanges made from your DXF or drawing, deburred and ready to use or weld. In-house laser cutting is coming in 2027.

Formed & bent parts

Press-brake bending, roll forming and tube bending for enclosures, guards, channels, rolled sections and handrails.

Welded assemblies

Frames, skids, stands, platforms, hoppers and machine bases — welded, ground and finished to your specification.

Stainless & aluminum

Food-, pharma- and water-grade stainless with clean blended welds; lightweight 5052 and 6061 aluminum frames and covers.

Prototypes & one-offs

Single test pieces with no minimum order — then repeat production when you’re ready.

Reference data

Specify it right the first time

Quick reference for engineers and buyers. Pick a tab — we’ll confirm the best process and material for your part when we quote.

Cutting process comparison (typical industry values)
Process	Best thickness range	Kerf (cut width)	Edge quality	Best for
Fiber laser	Thin sheet up to approx. 1″ mild steel	0.1–0.4 mm	Very clean, minimal dross, small heat-affected zone	Detailed parts, small holes, sheet metal
Saw cutting	Bar, tube, structural shapes	1.5–3 mm	Square cut, may need deburr	Tube, angle, channel and beam cut to length

Values vary with machine, material and gas. Your part’s process and tolerances are confirmed at quote.

Standard sheet steel gauges (manufacturers’ standard gauge)
Gauge	Thickness (in)	Thickness (mm)	Typical use
10 ga	0.1345	3.42	Heavy guards, brackets, base plates
11 ga	0.1196	3.04	Machine frames, heavy enclosures
12 ga	0.1046	2.66	Equipment panels, structural brackets
14 ga	0.0747	1.90	Enclosures, covers, chutes
16 ga	0.0598	1.52	Light enclosures, ducting, panels
18 ga	0.0478	1.21	Light covers and trim

Stainless and aluminum gauges differ slightly — specify thickness in inches or millimetres to avoid confusion.

Material selection guide
Material	Key properties	Typical applications
Mild steel (A36 / 44W)	Strong, weldable, economical; min. yield approx. 36 ksi (250 MPa) for A36	Frames, bases, brackets, structural parts — painted or galvanized
Stainless 304 / 304L	Good general corrosion resistance; easy to clean	Food and beverage equipment, guards, enclosures, water systems
Stainless 316 / 316L	Added molybdenum for chloride and chemical resistance	Marine, chemical, pharmaceutical and wash-down areas
Aluminum 5052	Excellent formability and corrosion resistance	Bent covers, panels, tanks, marine parts
Aluminum 6061-T6	Structural strength (yield approx. 40 ksi / 276 MPa), machines well	Frames, fixtures, machined brackets

FAQ

Metal fabrication questions

What metals do you fabricate?

Mild/carbon steel, stainless steel (including 304 and 316) and aluminum. We keep more than 300 material profiles in stock — plate, sheet, tube, angle, channel and bar — so most jobs start without waiting on material.

Do you offer laser cutting?

In-house laser cutting is coming to our Hamilton shop in 2027. Until then, send us your drawing and we’ll tell you the best way to get your cut parts made and finished.

Is there a minimum order?

No. We have a no-minimum-order policy — order a single piece to test us, or a full production run.

What do you need to quote a fabrication job?

A drawing (PDF, DXF, DWG or STEP), the material and thickness, quantity and your required date. A sketch or photo of an existing part also works — our team can help develop the drawing.

Can you finish and assemble the parts too?

Yes. We grind and blend welds to your specified finish, machine features after welding, and assemble complete weldments and machines — so you get finished parts instead of managing several suppliers.

Send us your drawings.

Upload a drawing, sketch or photo and we’ll come back with a quote. No minimum order — one piece or a production run.
