See how UNUS works in 40 seconds

One simple, repeatable portal frame — standardised, pre-engineered and scaled to your building.

How it works

From field to frame in three steps

No drawings to commission, no waiting on quotes. The UNUS configurator turns a handful of choices into a complete, buildable structure — then our design team checks it for your site.

01

Size it & price it

Pick your span, length and doors above. The price appears instantly — no contact details, no waiting.

02

Request your quotation

Happy with the price? Send us your details and site location. We review your requirements and send a formal quotation with the full scope and terms.

03

Build it

Every configuration produces a complete parts list — coded, counted and cut to length, down to the bolts — ready to deliver as one kit.

The system

Standardised down to the hole positions

Every primary component has been standardised. Each column and rafter is manufactured with all the connection holes required for any position within the building, so identical components can be used throughout the frame. Standardised purlins, side rails, roof bracing and wall bracing further reduce complexity while maintaining structural performance.

Common members

One main column, one roof brace, one side brace, one purlin and one side rail — the same common members used throughout the building, so there is no sorting, no matching and far less to get wrong on site.

Flexible door positions

Side rails are positioned to allow personnel doors to be fitted anywhere down the sides or the gables. Positions remain subject to the approved bracing layout, and bracing is relocated, never omitted.

Ready for a roller shutter

Roller doors can be fitted in most bays in the gable or the sides — bracings can be moved if necessary.

Checked for your site

Every UNUS building is individually checked by our design team against the wind, snow and loading requirements for its location.

What's in the kit

Every member, counted and coded

A duo-pitch steel portal frame: identical frames at 6 m centres, tied together with standardised cold-rolled purlins, side rails and bracing. Nothing bespoke, nothing missing.

Portal columnsThe main verticals of every frame, at each side of the span.
Portal raftersSupplied as matched pairs, meeting at the ridge.
Roof purlinsDown both slopes at 1.8 m centres, one piece per bay.
Wall railsAround all four walls, first rail 250 mm from the floor.
Gable columnsCentred across the gables at 5 m gaps.
Side bracing“K” brace in the first bay and every 5th bay — can be moved to miss door openings.
Roof bracingIn the first bay and repeated every 5 bays.
Why Unus

Engineered once. Built any size.

Traditional steel buildings are re-engineered from scratch for every enquiry. The UNUS system takes the opposite approach: one proven design, standardised parts, scaled to your site — with the confidence of a bespoke design and the speed of a standardised system.

No bespoke fees

The engineering is already done. You pay for steel, not design.

Reduced lead times

Standard sections and repeatable details mean the kit leaves the yard sooner.

Nothing forgotten

We produce parts lists for every component — every bolt-ready member accounted for.

Grows with you

Select your span and length — extra braces are added automatically every 30 m. The same system carries a 12 m workshop or a 120 m storage unit.

One system. Unlimited possibilities.

Free to use, no sign-up. Price your building in seconds and request your confirmed quotation.

Beyond the standard range

Need modifications, or something entirely bespoke?

The UNUS range stays standard — that's what makes it fast. For modified buildings, mezzanines, crane gantries or fully bespoke structural steelwork, talk to our parent company North Lincs Structures: a complete steel fabrication business behind every UNUS building.
