Mill Components & Assemblies
- Core Equipment
Mill components we work on every day
New. Rebuilt. Engineered. Assembled.
New. Rebuilt. Engineered. Assembled.
Edger housings, side trimmers, screwdowns, AGC beams, drive spindles, coil cars, equalizing beams — the large engineered components and assemblies that hold a hot strip or cold mill together. Built new, reverse-engineered, or rebuilt to OEM and beyond.
- Our Approach
The components you call about when something big has failed.
When an edger housing cracks, an AGC beam fails, or a coil car drops a coil, you are not calling around for catalog parts. You are calling for engineering, for capacity, and for someone who can actually build the thing — to print, to a reverse-engineered drawing, or to an upgraded design that solves the failure that just took your line down.
Mill Components & Assemblies is the work Mull Group is built for. Large structural components, engineered assemblies, and the heavy iron that holds a mill together. Our 100,000-pound machining capacity, in-house bronze foundry, weld and stress-relief shop, and full mechanical engineering team are the exact stack of capabilities this work demands. No subcontracting. No four-vendor handoff. One PO, one shop, one delivery date.
We work on hot mill and cold mill components across integrated steel, mini-mills, and finishing operations. From a single replacement spindle to a complete edger housing rebuild with new bronze, new bushings, stress-relieved welds, and machined-to-print final assembly — the scope can be one part or the whole package.
- Three Ways We Deliver
Build it new. Engineer it smarter.
Build New

- In-house bronze components and bushings
- Full traceability and test documentation
Engineer & Upgrade
- Reverse engineering from sample, scan, or teardown
- Capacity upgrade redesign
- Root-cause failure analysis
- Production drawings and BOMs
Rebuild & Refurb
- Magnetic particle / dye penetrant inspection
- Weld repair plus stress-relief in-house
- Bushing replacement with cast bronze
- Complete reassembly and documentation
- Specifications

- Our Offering Includes
Mill components. we work on every day.
01 Hot Mill Components Hot Mill
Engineered components for hot strip mills, plate mills, and roughing/finishing stands. Heavy structural and dynamic equipment that handles the highest loads on a steel mill.
02 Cold Mill & Finishing Components Cold Mill
Engineered components for cold rolling mills, tandem mills, processing lines, and finishing operations. Precision and tension-control equipment for high-quality strip production.
03 Cranes, Lifting & Handling Hot & Cold Mill
Crane components, lifting devices, and material handling equipment that support coil and slab movement throughout integrated mill operations.
04 Caster & Steelmaking Components Caster · BOF · LMF
Continuous caster components, runout equipment, and steelmaking support equipment for integrated producers and mini-mills.
05 Mill Frames & Structural Assemblies Hot & Cold Mill
Heavy structural assemblies, frames, and rail systems — the backbone steel that holds the mill together. Built or rebuilt with weld, stress-relief, and machining all under our roof.
06 Coke Oven & Blast Furnace Support Integrated Steel
Components and assemblies for coke ovens, blast furnaces, sintering plants, and other integrated-mill upstream operations.
