We roll steel profiles to your drawing — weather strip, C and hat sections, gutters, purlins — for bus and coach body builders, fabricators and OEMs. Send a section and we will quote the tooling, the rate per metre, and a first-off sample.

Profile range

Sections we roll every week

These run on existing tooling, so lead times are short and there is no development cost. Anything outside the range, we make the tool for.

PK-01Weather stripGI / SS

Weather strip

Glazing and door channel with inturned lips that grip the rubber beading and shed water clear of the joint.

Drawing & specs

PK-02C sectionGI / CRCA

C section

The workhorse channel. Body framing, pillars, floor bearers and any run that needs stiffness without weight.

Drawing & specs

PK-03Hat sectionGI / CRCA

Hat section

Flanges sit flat on the panel and rivet or spot-weld straight down. Roof sticks, cant rails, floor and side stiffeners.

Drawing & specs

PK-04GutterGI / Alu

Gutter

Roof drip rail with a return lip, so rain runs to the downpipe instead of down the window line and into the body.

Drawing & specs

PK-05Z sectionGI

Z section

Purlins and rails that lap end to end over a support, so long runs carry more with fewer joints.

Send a DXF, a PDF or a sample of the old part. We develop the flower, cut the rolls and run a first-off for your approval.

How it works

In-house tooling

The tool is the hard part

Anyone can bend metal. Getting a section to hold its dimension down a 6-metre length, without twist, edge wave or springback, is decided before the coil is loaded — in the flower pattern and the roll design. We do that work ourselves, which is why we can change a section without waiting on an outside tool room.

  • Profile development. Developed width, bend allowance and pass count worked out from your section, not guessed.
  • Rolls cut and hardened in-house. New tooling in [2–3 weeks], and corrections in days rather than months.
  • First-off before production. You check the sample against your drawing and sign it off. Only then do we run the order.
  • Your tooling stays yours. Stored here, logged against your part number, ready for the repeat order.

Custom roll forming

Continuous cold forming from coil, on lines set up for the gauges bus body work actually uses.

Tool & die room

Roll design, machining and hardening under our own roof, so a change to your section is our problem to solve.

Cut to length

Flying cut-off on the line. You get the lengths your jig needs instead of stock bars your team has to trim.

Punching & notching

Holes, slots and end notches punched in line to your drawing, so the part arrives ready to fix.

Material sourcing

GI, CRCA, stainless and aluminium coil bought to spec, with mill test certificates when you need them.

Inspection

Section, length and hole position checked against the approved first-off, batch by batch.

How a job runs

Drawing to dispatch

Five steps, in this order, every time. You are asked to approve once — at the first-off — and nothing goes into production until you do.

  1. Step 01

    Send the section

    A DXF, a PDF, a marked-up sketch, or the old part in a courier bag. Any of them is enough to start.

  2. Step 02

    Flower & tooling

    We develop the flower pattern, fix the pass count and cut the rolls. You get tooling cost and rate per metre before anything is machined.

  3. Step 03

    First-off sample

    We run a trial length and send it with a dimension report. You check it against your drawing and approve.

  4. Step 04

    Production

    Rolled, cut to length, punched and notched to the approved sample, checked batch by batch.

  5. Step 05

    Dispatch

    Bundled with edge protection and scheduled against your build plan, so sections land when the line needs them.

Who we supply

Built around bus bodies, useful well beyond them

Bus and coach work sets our tolerances and our gauges. Everything else we roll benefits from the same tooling discipline.

Bus & coach body building

Our home trade. Framing, glazing and roof sections that arrive matched to your jig.

Weather strip · Gutter · Hat · C section

Commercial vehicles & trailers

Load body framing, floor bearers and side rails in gauges that take the hammering.

C section · Z section · Angle

Solar mounting

Purlins and rails for module structures, pre-punched so the site crew only has to bolt.

Z section · Hat · C section

Storage racking

Uprights and beams rolled to repeat dimensions, batch after batch.

C section · U channel · Custom

Pre-engineered buildings

Roof and wall purlins in long lengths, lapped Z or plain C to your structural drawing.

Z section · C section

Panel & cold room systems

Edge profiles and trims where the section has to be clean enough to seal against.

Next step

Send us a section

A drawing, a photo of the old part, or just the dimensions written down. We come back with tooling cost, rate per metre and a lead time — normally within one working day.
