Program and solutions
QSteelCAD's four main jobs, choosing software, questions and releases.
- HomeLight gauge steel software: QSteelCAD builds wall panels and roofs from a DXF plan, checks rivet holes, lengths and clashes, and writes rollforming files.
/en - SolutionsEvery step from plan to rollforming line lives in the same file. Moving from one solution to the next never means redrawing the model.
/en/solutions - Create architecture from planWalls, doors and windows in a DXF plan are recognised; in three steps wall panels are built with studs, lintels and bracing.
/en/solutions/plan-to-architecture - Automatic roofBuilds hip, gable or mixed roofs with trusses, ceiling and roof panels in one window.
/en/solutions/automatic-roof - Production and CAMEvery profile is written with its length, holes and notches to the .bde file your rollforming machine reads.
/en/solutions/production-and-cam - Presentation and costingRenders with cladding, rooms and furniture; quantities, cost, rivet and screw counts from the same model.
/en/solutions/presentation-and-costing - How to choose light gauge steel software: 10 questions before you buyWhat decides light gauge steel software is not the screenshots but how many manual hand-offs stay between your plan and your machine. A checklist, what to do in a demo and which claims to question.
/en/blog/how-to-choose-light-gauge-steel-software - What is the difference between general CAD and light gauge steel software?General purpose CAD knows lines; light gauge steel software knows profiles. The difference is not on screen but in how much information is carried by hand from drawing to production.

/en/blog/topic/regulations - Turkey's light steel regulation takes effect on 1 January 2027: what changes?The regulation published on 17 May 2026 brings the design, calculation and construction principles of light steel buildings into a single text. We compared its annex with Chapter 10 of the Turkish Building Earthquake Code 2018 (TBDY 2018); here is what manufacturers and designers need to know.
/en/blog/turkey-light-steel-regulation-2027 - Galvanizing in light steel: 180 or 275 g/m² for each of the 81 provinces?The 2027 light steel regulation sets the zinc coating amount province by province. Which class is your site in, when is the province table not enough, and how is a cut surface repaired? The full table is in this article.
/en/blog/zinc-coating-by-province-turkey - Light steel panel rules 2027: 0.9 mm studs, 625 mm spacing and bridgingSection 6 of the regulation concerns everyone who produces panels directly. From stud section to bridging screws, from cabinet loads to the 10.5 metre limit, we have collected all the panel rules in one article.
/en/blog/light-steel-panel-rules-2027 - Light steel material rules 2027: 250 MPa, the DX grade ban and screw requirementsAfter 1 January 2027, which sheet can you use, in what thickness, with which screws? We read Sections 2 and 3 of the regulation from the point of view of buying coil.
/en/blog/light-steel-material-rules-2027 - TBDY 2018 Chapter 10: braced panel rules, clause by clauseWhat does the light steel chapter of the Turkish Building Earthquake Code ask for in braced panels? We read every clause, from classification and net section checks to bridging and diaphragms, with its meaning on site.
/en/blog/tbdy-2018-chapter-10-braced-panels - Light steel floor rules 2027: deflection table, 8 Hz and web stiffenersA floor is now calculated not only for strength but also for deflection and vibration.

Bracing systems
X strap, K, V and sheathed panels: how they work and how to tell them apart.
- Light steel bracing systems: X, K, V and sheathed panelsX strap, K, V and sheathed panels: how they work and how to tell them apart.
/en/blog/topic/bracing-systems - Bracing systems in light steel: a guide to X, K, V and sheathed panelsA light steel building resists lateral load in one of two ways: braced panels or sheathed panels. This guide explains how each system works, how they differ, and what the Turkish rules require.
/en/blog/light-steel-bracing-systems-guide - What is X-strap bracing and how does it work in a light steel wall?Two flat steel straps hold a wall panel against lateral load. But the two straps do not work at the same time, and you cannot read a strap correctly without knowing where the force goes.
/en/blog/what-is-x-strap-bracing - What is K-bracing? Compression, node and end bearing in profile bracingK-bracing is not like a strap: it is expected to carry compression too. So the calculation rests on section buckling, the node and how the profile end bears.
/en/blog/what-is-k-bracing - Bracing, bridging, diaphragm, temporary prop: four look-alike dutiesIn a light steel structure, not every inclined or horizontal member is a lateral load system. Confusing the duties of four similar members gets the wrong part removed or trusted in the wrong place.

Load path and connections
The route force takes from diaphragm to foundation, and the connections that keep it intact.
- Load path and connections: how force reaches the foundationThe route force takes from diaphragm to foundation, and the connections that keep it intact.
/en/blog/topic/load-path-and-connections - Lateral load path in a light steel building: from roof to foundation, step by stepWind and earthquake force follows an unbroken path through the building. Bracing is only one link in it; to see where the chain breaks, you have to follow the links one by one.
/en/blog/lateral-load-path-roof-to-foundation - What is the difference between a hold-down and a shear anchor?Both sit at the base of the panel and both fix to concrete, but they resist different forces. One stops the panel lifting, the other stops it sliding; neither replaces the other.
/en/blog/hold-down-vs-shear-anchor - Gusset plates and strap end connections: how does force pass into the frame?A brace is only as strong as its connection. If the gusset, the screw group and the net section do not work together, the joint fails before the strap yields. That is why the end connection has to be read interface by interface.
/en/blog/gusset-plates-and-strap-end-connections - Floor and roof diaphragms: who delivers the load to the braced wall?A strong braced wall is useless if nothing delivers the load to it. The diaphragm is the horizontal plate that does this job, working together with its sheathing, joists, tracks and screws.
/en/blog/floor-and-roof-diaphragms - How doors, windows and services affect a braced panelA brace that misses the opening does not satisfy every condition. An opening changes the usable length of the panel, its chord studs and its anchors; service holes come with their own rules.

Production and erection
From drawing to production, from factory to site: the practical side of the work.
- Light steel production and erection: from factory to siteFrom drawing to production, from factory to site: the practical side of the work.
/en/blog/topic/production-and-erection - Light steel fabrication and erection checklist: how to use Table 10.1The 2027 light steel regulation ties site inspection to a list with eight headings. We set out the items in plain language, wrote down what to add for bracing, and showed where in the factory the list should be filled in.
/en/blog/fabrication-and-erection-checklist - A temporary prop is not permanent bracing: how to keep the frame stable during erectionA building must stand at every stage of erection, not only as finished. The 2027 light steel regulation makes temporary stability a separate heading for the first time. What does a prop do, and when is it removed?
/en/blog/temporary-props-and-erection-stability - Strap tension and tensioners: why does slack bracing cause problems?The regulation says it in one sentence: strap bracing connections are made taut. A slack strap engages late once load arrives, and the wall moves more than expected. How is tension achieved, and when is it checked?
/en/blog/strap-tension-and-tensioners - Why is saving bracing in CAD as a line between two points not enough?The same X drawing can be a strap or a profile, a permanent system or a temporary prop. If the model does not carry that difference, the drawing looks right while production and checking go the wrong way.

Glossary terms
Short definitions of light gauge steel and rollforming terms.
- Load pathThe sequence of members and connections a force passes through from where it acts to the ground. If one link is missing the system is not complete.
- Braced panelA light steel wall panel that resists lateral load with bracing members. TBDY 2018 classes this system as Limited Ductility Level.
- Sheathed panelA light steel wall panel that resists lateral load with sheathing fixed by screws. For sheathing to count as structural, stud spacing is at most 625 mm.
- X strap bracingTwo flat steel straps fixed corner to corner on a panel face. It works in tension only; when the load reverses, the other strap takes over.
- K bracingA K-shaped layout of C-profile diagonals inside a panel bay. It carries tension and compression and needs buckling and node checks.
- Chord studThe stud at the end of a load-bearing panel segment. It carries tension and compression from bracing or sheathing and connects to the anchor.
- BridgingA horizontal member fixed between studs to shorten their buckling length. It holds the stud; it does not carry the building's lateral load.
- Hold-downA connection that transfers tension in the chord stud at a panel end to the structure below.
- Shear anchorA connection that transfers horizontal force at the panel base to the foundation. The number comes from the shear force to be transferred.
- Gusset plateA corner plate that spreads the force of a bracing member into studs and tracks.
- DiaphragmThe in-plane action of a floor or roof that collects lateral force and delivers it to the lateral load-resisting walls.
- CollectorA line that gathers diaphragm force into a lateral load-resisting panel or carries chord force.
- EccentricityA force acting away from a member's axis. With a strap on one face, the moment T·e goes into the stud design.
- Net sectionThe cross-section left after holes are taken out. Net section strength is checked at bracing connections.
- Overstrength factorA TBDY factor that sizes the members and anchors connected to bracing for amplified forces.
- Temporary propAn inclined erection support that holds a panel until the permanent lateral system is complete. It is not permanent bracing.
- Strap tensionerAn erection part used to fix strap bracing under tension.
- Light gauge steelA building system made of profiles cold-formed from thin steel sheet. Wall, roof and floor structures are built from these profiles.
- RollformingA production line where steel strip passes through successive rollers and takes the shape of a profile. Stations along the line punch holes, notch, flatten and finally cut the profile.
- .bde fileThe production file a rollforming line reads. Each line describes one profile: its name, length and operation positions. QSteelCAD writes one .bde and one CSV per section.
- Machine profileThe setting that defines which operations a rollforming line can perform. QSteelCAD ships with Rollform-80, 90, 140, 200 and 300; operations a profile doesn't support never reach the line.
- StationA unit on a rollforming line that performs one operation. In QSteelCAD, stations H, F, N, S, S2 and S3 switch on or off per machine profile.
- PanelA wall, roof or ceiling section made of profiles, produced and then assembled on site. QSteelCAD builds panels from a DXF plan.
- StudA vertical load-bearing profile in a wall panel. It has a lipped C section and forms the main structure of the panel.
- TrackThe unlipped U profile that connects the studs at the bottom and top of a wall panel.
- LintelThe horizontal member above a door or window opening. It transfers the load from above to the studs on either side of the opening.
- Corner bracingDiagonal members added at wall panel corners. In QSteelCAD you choose None, Zigzag or K; bracing adds wall steel, and its adequacy is for the project engineer to approve.
- TrussThe framed member that carries the roof. In QSteelCAD, Automatic roof places trusses by spacing and shows how many you will get before creating them.
- Girder trussA truss that carries other trusses at a junction. QSteelCAD flags these joints as needing an engineer's approval.
- Hip roofA roof that slopes on all four sides. In Automatic roof the end type can be half truss or cut truss.
- Gable roofA roof that slopes on two sides. It is one of the shapes Automatic roof builds.
- NotchA cut in a profile's web or flange for a connection. Written in the n: field of a .bde line.
- FlattenAn area of a profile flattened for a connection. Written in the f: field of a .bde line.
- SwageAn operation that narrows a profile's section. Written in the w: field of a .bde line.
- Service holeA small or large hole in a profile for services. Written in the s: and l: fields of a .bde line.
- DXFA file format for moving CAD drawings between programs. QSteelCAD reads DXF plans; it does not read DWG, so the file must be saved as DXF.
- TakeoffThe list of material quantities in a building. QSteelCAD calculates it from net area, waste rate and unit price, and never invents a price for a material without one.
