Capabilities

Everything from a single stair rail to a full structural package

One shop, one crew, one point of contact. We detail it, cut it, weld it, coat it, and set it — so nothing gets lost between trades.

01

Structural Steel

Beams, columns, joists, and moment frames detailed in-house and erected to sequence. Mill certs on every heat.

02

Custom Fabrication

One-off brackets, equipment frames, hoppers, chutes, and weldments built from your prints or a napkin sketch.

03

Certified Welding

AWS D1.1 structural and D1.3 sheet. MIG, TIG, and stick on carbon, stainless, and aluminum.

04

CNC Plasma & Laser

Profiles cut to ±0.015" on plate up to 1¼". Nesting done in-house to keep drops and cost down.

05

Stairs & Handrail

Egress stairs, mezzanines, and architectural rail — code-compliant, shop-fit, and delivered ready to set.

06

Repair & Field Service

Breakdowns don't wait. Mobile rigs for on-site cutting, welding, and structural repair, including nights and weekends.

How We Work

Four steps, no surprises

01

Takeoff

Send prints or a sketch. We price from the drawing and flag anything that will bite you later.

02

Detailing

Shop drawings back for approval, typically inside a week. Nothing gets cut until you sign.

03

Fabrication

Cut, fit, weld, and coat under one roof. You get photos at fit-up, not excuses at delivery.

04

Delivery & Set

Trucked to sequence and set by our own crew. We're not done until it's plumb and signed off.

“We've had Ironline on six projects now. They're the only fabricator we don't have to chase — the steel shows up when they said, and it fits.”
