## Program and solutions

- [Home](https://qsteelcad.com/en): Light gauge steel software: QSteelCAD builds wall panels and roofs from a DXF plan, checks rivet holes, lengths and clashes, and writes rollforming files.
- [Solutions](https://qsteelcad.com/en/solutions): Every step from plan to rollforming line lives in the same file. Moving from one solution to the next never means redrawing the model.
- [Create architecture from plan](https://qsteelcad.com/en/solutions/plan-to-architecture): Walls, doors and windows in a DXF plan are recognised; in three steps wall panels are built with studs, lintels and bracing.
- [Automatic roof](https://qsteelcad.com/en/solutions/automatic-roof): Builds hip, gable or mixed roofs with trusses, ceiling and roof panels in one window.
- [Production and CAM](https://qsteelcad.com/en/solutions/production-and-cam): Every profile is written with its length, holes and notches to the .bde file your rollforming machine reads.
- [Presentation and costing](https://qsteelcad.com/en/solutions/presentation-and-costing): Renders with cladding, rooms and furniture; quantities, cost, rivet and screw counts from the same model.
- [How to choose light gauge steel software: 10 questions before you buy](https://qsteelcad.com/en/blog/how-to-choose-light-gauge-steel-software) (2026-11-06): What 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.
- [What is the difference between general CAD and light gauge steel software?](https://qsteelcad.com/en/blog/general-cad-vs-light-gauge-steel-software) (2026-11-06): 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.
- [Frequently asked questions](https://qsteelcad.com/en/faq): Answers about QSteelCAD and light gauge steel: setup, plan to model, roofs, production, takeoff, licensing, Turkey's 2027 regulation and structural topics.
- [Release Notes](https://qsteelcad.com/en/release-notes): Every update is announced inside the program and keeps your licence, settings and projects.

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.
- [Galvanizing in light steel: 180 or 275 g/m² for each of the 81 provinces?](https://qsteelcad.com/en/blog/zinc-coating-by-province-turkey) (2026-11-06): 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.
- [Light steel panel rules 2027: 0.9 mm studs, 625 mm spacing and bridging](https://qsteelcad.com/en/blog/light-steel-panel-rules-2027) (2026-11-06): Section 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.
- [Light steel material rules 2027: 250 MPa, the DX grade ban and screw requirements](https://qsteelcad.com/en/blog/light-steel-material-rules-2027) (2026-11-06): After 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.

How high can you go with modules alone, and which rule applies in a hybrid building? A summary of Section 12 is in this article.

## Bracing systems

- [Light steel bracing systems: X, K, V and sheathed panels](https://qsteelcad.com/en/blog/topic/bracing-systems): X strap, K, V and sheathed panels: how they work and how to tell them apart.
- [Bracing systems in light steel: a guide to X, K, V and sheathed panels](https://qsteelcad.com/en/blog/light-steel-bracing-systems-guide) (2026-11-06): A 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.
- [What is X-strap bracing and how does it work in a light steel wall?](https://qsteelcad.com/en/blog/what-is-x-strap-bracing) (2026-11-06): 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.
- [What is K-bracing? Compression, node and end bearing in profile bracing](https://qsteelcad.com/en/blog/what-is-k-bracing) (2026-11-06): K-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.
- [Bracing, bridging, diaphragm, temporary prop: four look-alike duties](https://qsteelcad.com/en/blog/bracing-bridging-diaphragm-temporary-props) (2026-11-06): In 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

- [Load path and connections: how force reaches the foundation](https://qsteelcad.com/en/blog/topic/load-path-and-connections): The route force takes from diaphragm to foundation, and the connections that keep it intact.
- [Lateral load path in a light steel building: from roof to foundation, step by step](https://qsteelcad.com/en/blog/lateral-load-path-roof-to-foundation) (2026-11-06): Wind 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.
- [What is the difference between a hold-down and a shear anchor?](https://qsteelcad.com/en/blog/hold-down-vs-shear-anchor) (2026-11-06): 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.
- [Gusset plates and strap end connections: how does force pass into the frame?](https://qsteelcad.com/en/blog/gusset-plates-and-strap-end-connections) (2026-11-06): 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.
- [Floor and roof diaphragms: who delivers the load to the braced wall?](https://qsteelcad.com/en/blog/floor-and-roof-diaphragms) (2026-11-06): 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.
- [How doors, windows and services affect a braced panel](https://qsteelcad.com/en/blog/openings-services-and-braced-panels) (2026-11-06): A 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

- [Light steel production and erection: from factory to site](https://qsteelcad.com/en/blog/topic/production-and-erection): From drawing to production, from factory to site: the practical side of the work.
- [Light steel fabrication and erection checklist: how to use Table 10.1](https://qsteelcad.com/en/blog/fabrication-and-erection-checklist) (2026-11-06): The 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.
- [A temporary prop is not permanent bracing: how to keep the frame stable during erection](https://qsteelcad.com/en/blog/temporary-props-and-erection-stability) (2026-11-06): A 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?
- [Strap tension and tensioners: why does slack bracing cause problems?](https://qsteelcad.com/en/blog/strap-tension-and-tensioners) (2026-11-06): 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?
- [Why is saving bracing in CAD as a line between two points not enough?](https://qsteelcad.com/en/blog/modelling-bracing-in-cad) (2026-11-06): 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.

- [Diaphragm](https://qsteelcad.com/en/glossary#diaphragm): The in-plane action of a floor or roof that collects lateral force and delivers it to the lateral load-resisting walls.
- [Collector](https://qsteelcad.com/en/glossary#collector): A line that gathers diaphragm force into a lateral load-resisting panel or carries chord force.
- [Eccentricity](https://qsteelcad.com/en/glossary#eccentricity): A force acting away from a member's axis. With a strap on one face, the moment T·e goes into the stud design.
- [Net section](https://qsteelcad.com/en/glossary#net-section): The cross-section left after holes are taken out. Net section strength is checked at bracing connections.
- [Overstrength factor](https://qsteelcad.com/en/glossary#overstrength-factor): A TBDY factor that sizes the members and anchors connected to bracing for amplified forces.
- [Temporary prop](https://qsteelcad.com/en/glossary#temporary-prop): An inclined erection support that holds a panel until the permanent lateral system is complete. It is not permanent bracing.
