The connectionLX-02

Bolted ball-node construction.

Seven parts and no site welding. Pull the slider to take one joint apart; the labels identify each part.

100%

One axis. Ball bore, bolt, sleeve, cone and tube are concentric on the member axis in both states.

Sleeve reads as a rectangle. A hex prism seen side-on, with the two hex edges shown as lines. It sits between the ball's milled face and the cone.

Pin is radial. It goes through the sleeve wall into the slot in the bolt shank, so turning the sleeve turns the bolt into the ball.

Bolt head inside the cone. The shank passes out through the cone's small end. The thread runs into the ball.

V ring behind the weld. Backing ring inside the tube end. The cone-to-tube girth weld is the only weld, done in our shop.

ASSEMBLY LOGICThe bolt and cone are fitted before the girth weld. On site the fitter turns the hex sleeve, the pin drives the bolt into the ball, and the sleeve ends up clamped between the ball face and the cone.

GeometryLX-03

The grid takes the shape of the building.

A space frame is a method, not a shape. Pick a form and drag it round. The connection logic is identical; only the geometry changes.

Selecting the systemLX-04

Size your roof in ten seconds.

Set the building footprint. You get a first-pass depth, grid module and steel range, and an honest answer on whether a space frame makes sense.

Clear span (width)40m

Building length60m

Application

First pass for a uniformly loaded double-layer grid on four-side support, depth ≈ span / 20. Two-side support, heavy suspended loads, cantilevers and free-form all change it. Steel on a 20 to 30 kg/m² planning basis. Illustrative only; not structural design, a quantity take-off or a quotation.

INDICATIVE ONLYAll parameters shown are indicative. Final shape, depth and steel weight can only be determined after full structural design.

ApplicationsLX-05

Where the system is used.

Anywhere the floor has to stay open: hangars, halls, domes, stockpiles and transit roofs.

Double-layer space frame roof over a hangar — **Hangars and assembly halls**Clear-span maintenance and storage, 30 – 80 m

Curved space frame roof over a transit hall — **Transit and terminal halls**Long-span roofs over live passenger floors

Indoor sports hall under a space frame — **Sports hall**Column-free playing area

Flat space frame roof over an indoor recreation hall — **Indoor recreation**Long span over an insulated envelope

Cylindrical space frame shell over a stockpile — **Stockpile and bulk storage**Long-span shells over coal yards and silos

Glazed lattice dome under construction — **Domes and glazed roofs**Lattice shells carrying glass, 15 – 70 m

ManufacturingLX-07

Members are manufactured in Pakistan, on our own line.

From raw tube to a finished, tagged member in six steps, with length held to the cut list rather than to a fitter's mark.

CNC plasma cutting and bevelling line — 01Cut and bevel
CHS cut to the exact length on the cut list and bevelled for the weld.

Cone-head positioning machine — 02Position the cones
Cones set on both ends and tack-welded, with the bolt fitted inside.

Automatic dual-head girth welding — 03Girth weld
Both ends welded at once by an automatic dual-head machine, to AWS D1.1.

Coated members on the finishing line — 04Surface treatment
Blast-cleaned and coated or galvanised to the project specification.

CNC machining of a ball node — 05Node machining
Threaded bores cut on computed axes, so the grid closes on site.

Finished members, capped and tagged — 06Tag, pack, dispatch
Every member marked to its grid position and packed by erection zone.

Materials and standardsLX-09

Specified to American standards.

Material specifications and certificates are reviewed for each project. Alternative grades require the structural engineer’s approval; matching labels alone do not establish equivalence.

Draft specification references for engineering review. Listed certifications and their scope must be verified before publication.

Criterion	Pre-engineered portal frame	Bolted space frame
Structural action	Planar frames spanning one direction	3D grid, load shared both ways
Economic clear span	Efficient to roughly 30 m	Efficient from ~20 m to beyond 100 m
Internal columns	Often needed on wide buildings	Not required within the grid
Self-weight	Baseline	Roughly 30% lighter at large span
Site connections	Field welding common at secondary work	Bolted at every node
Roof geometry	Gable or duo-pitch	Flat, vaulted, domed, saddled, free-form
Redundancy	Loss of a member can form a mechanism	Multiple load paths
Heavy crane loads	Well suited	Needs dedicated crane columns

A portal frame is the better answer below roughly 20 to 30 m on a simple plan with heavy crane duty. SEED supplies both, so the advice is not tied to one product.

Member sizes are not published. Diameter, wall thickness and node size are outputs of the structural analysis for each project, issued on the stamped drawings.
