Manufacturing · Structural Steel Fabricator Management Software

Piece marks, heat numbers, erection sequence and tonnage billing in one system.

Manage structural steel packages, detail drawing revisions and piece mark lists, with one numbered line per member. Mill test certificates are kept by heat, the mill’s cast number, alongside sawing, welding, shot blasting and zinc phosphate priming. Truck loading lists and the tonnage stage bill are produced from the same piece marks. Every column, rafter and purlin carries its revision and its heat. The shop builds from the current drawing, and site receives members in lift order.

  • Sections, plate grades and stage names entered as your shop uses them
  • Open packages, piece lists and vendor list migrated
  • Edits to stages and loading rules made by GullySystem staff when asked

Structural steel fabricators keep packages, piece mark lists, drawing revisions, mill certificates, fabrication stages and dispatch in Structural Steel Fabricator Management Software, which GullySystem configures for the shop. Each member carries its drawing revision, its heat and its place in the erection sequence. Cleats and bolt sets are counted out, and stage bills follow fabricated and delivered tonnage.

Where it breaks today

What goes wrong before the software.

Revisions reach the shop late

The engineer issues Revision C of a detail and it travels through two inboxes. Meanwhile the cutting list pinned beside the beam line still shows the old length. The saw keeps cutting.

Mill certificates are filed by heat, members are not

A certificate lists a heat, not a beam. When the client’s third-party inspector asks which mill certificate covers column C14, finding the answer eats an afternoon.

Piece lists live in several spreadsheets

The detailer, the buyer and the shop each keep a list of marks. They disagree on weights and quantities. Nobody trusts any of them when the detailer’s export arrives.

Trucks are loaded by what is ready

The yard loads finished members as they leave the line. The crane needs bay one first. It receives bay four. The erection gang stands idle beside a half-built frame.

Bolt sets are counted by eye

Cleats, stiffeners, base plates and high strength bolt sets are bagged by hand. A short count is found only when the erection crew cuts open the bag. The crane hire is already running.

Stage bills are argued weight by weight

Fabricated, delivered and invoiced tonnage come from three different sources. The client’s quantity surveyor asks for a weight sheet. Nobody has one.

How it runs

How the work flows through it, step by step.

  1. 1

    Package and drawings

    A building package is opened with its client, contract and general arrangement drawing set. Each shop drawing is stored with its revision letter and the date it was issued.

  2. 2

    Piece list and material

    Marks are listed with section, length and weight. The total steel by grade, such as S355 plate or beam and column sections, drives purchase orders to the stockist or rolling mill.

  3. 3

    Receipt and heat records

    Sections and plate arrive with mill test certificates. Each heat is booked in against its cast number, and the yard rack view shows which heats are on hand.

  4. 4

    Fabrication

    Marks pass through sawing, drilling on the beam line, fit up, welding and inspection. Each stage records who did it and when. Revisions flag marks already cut.

  5. 5

    Surface treatment

    Members go to shot blasting and priming, in house or at an outside yard, and return with coating thickness and paint batch recorded against each mark.

  6. 6

    Loading and billing

    Trucks are loaded to the erection sequence and the site’s receipt is compared with the delivery note. Stage bills are raised on the weights in the piece list.

Modules

What is inside.

Every module can be switched on, left out or changed to match how your team already works.

Packages and contracts

Open each building as a package with its client, drawing set, erection schedule and billing terms, and watch the progress of every bay from foundation to ridge.

Drawing register and revisions

Store shop drawings by revision letter. A new issue flags the marks it touches and shows whether any are already sawn, drilled or primed.

Piece mark list

Hold every mark with section, length, weight, bay and lift number, loaded from the detailer’s export file or entered by hand.

Material purchase and mill certificates

Raise orders for sections and plate against the package, book in each cast with its test certificate and see the offcuts and full lengths left on the rack.

Heat assignment to members

Assign cut pieces to a heat so that each beam or column opens its own mill certificate for an inspector, and a rejected heat leads to every member cut from it.

Fabrication stage board

Track every mark through sawing, drilling, fit up, welding, inspection and surface treatment, with a count of marks sitting at each stage.

Inspection and non conformance

Record dimensional checks, ultrasonic or magnetic particle weld tests and defects against the mark, with the corrective action and who closed it.

Outside processes

Track members sent for blasting, hot dip galvanising or painting, with date out, yard, coating specification and date returned.

Loose items and bolt sets

List cleats, stiffeners, base plates and high strength bolt sets per connection, count them at the yard gate and note shortages reported from site.

Loading plan and delivery notes

Plan low-bed trailers by erection sequence, print the delivery note with mark numbers and weights, and record the site’s receipt.

Tonnage stage bills

Raise bills from fabricated and delivered tonnage with the weight sheet attached, then follow retention held and balances still due.

Solutions inside

The business modules it is built from.

Each one is also available on its own, or inside a system built for you.

  • Project Document Management

    Shop drawings are held by revision letter and issue date, so a new issue shows which marks it changes and whether they are already cut.

  • Bill of Materials

    Every mark lists its section, length and weight, and the totals by grade and size drive the plate and sections to be ordered.

  • Purchase Order Management

    Orders for sections and plate are raised against a package and tracked until the cast arrives with its test certificate.

  • Batch and Serial Tracking

    A heat number is attached to each cut piece, so a beam opens its own certificate and a rejected cast leads to every member.

  • Work Order Management

    Each mark moves through sawing, fit up, welding and inspection as a work order, with the welder and date at every stage.

  • Quality Control

    Dimensional checks and ultrasonic weld tests are recorded against the mark, and a defect stays open until a named person closes it.

  • Job Work Management

    Members sent for blasting, hot dip galvanising or painting are tracked as job work, with the yard, the coating specification and the return date.

  • Invoice Management

    Stage bills are raised on the fabricated or delivered weight in the piece list, with the weight sheet kept behind each invoice.

Services

How we would put it in.

Setup, data migration, integrations and anything built on top.

Who uses it

One system, each person sees their part.

For owners

See tonnes fabricated and delivered by package, revisions waiting for acknowledgement, and stage bills raised against what the client has paid.

For project managers

Watch each package by bay, release shop drawings to the floor and keep the site’s delivery request beside what the yard has ready to ship.

For the detailing and planning desk

Load piece lists, issue revision letters and see which marks they hit before the band saw has touched any steel.

For shop and yard supervisors

Mark pieces through each stage, assign heats from the rack and load trailers to the lift sequence the site engineer asked for.

For quality staff

Record weld inspections, match mill certificates to members and close non conformance reports with a named owner against each.

Honest answer

When it is not the right choice.

Made to fit

Adapted to your business before it goes live.

You are not handed a login and left to it. The product is set up around your records, your people and the tools you already use.

Sections and grades

Your section list, plate grades and weight tables are entered first, so tonnage is calculated the way you quote it, down to the last gusset.

Fabrication stages

The stages a mark passes through, and any hold points before blasting or priming, are set to your shop’s own sequence.

Piece list import

A layout for the export from your detailing package is agreed during setup, so marks load without retyping a single line.

Packages and balances migrated

Packages still running, the vendor list and stage bills awaiting payment are imported from the sheets you use today.

Hosted by GullySystem

The system runs on our servers, and the office, the yard and the site engineer open the same piece list from any browser.

Common questions

Questions owners ask before a demo.

Does it replace our detailing package?

No. The detailer draws and produces the lists. This system holds the marks, revisions, heats and dispatch plan that follow from them. It never redraws a connection.

What happens when a drawing revision arrives after cutting?

Affected marks are flagged with their stage. The supervisor sees which are already sawn or primed and decides what to rework or scrap.

Can an inspector see the certificate for a single beam?

Yes, once cut pieces have been assigned to heats. The member’s record opens the mill certificate, and the same heat lists every other member cut from it.

How are trucks planned for the crane?

Each mark has a bay and lift number. The loading plan sorts by those numbers, and the trailer’s list shows what is missing from the sequence.

Are loose items handled?

Yes. Cleats, base plates and bolt sets are listed per connection. Each bag or crate has a number. The site’s receipt is checked against it.

Can it handle work done by outside blasting and painting yards?

Yes. Members go out with a note of the coating system, are tracked while away and are booked back with the coating thickness recorded.

How is tonnage worked out for billing?

Weights come from the piece list and the section tables you enter. Fabricated and delivered tonnage are kept apart, so each stage bill states which it is based on.

Can we move open packages across?

Yes. The planning desk imports piece lists, drawing registers and unpaid stage bills, then compares weights with the old sheets before the first live package.

Who owns our drawing and piece data?

You do. Before work begins, the quotation states the file format in which a package’s records can be exported.
