A box corner is a node with 5 or 6 outlets in a cube shape that lets you join trusses in several planes at once — horizontally and vertically. It's needed for 3D structures: full portals with vertical supports, cube frameworks, ground-support structures where trusses go both up and sideways. It's one of the most important nodes for complex stages. Box corners are bulkier and pricier than flat corner blocks. For simple horizontal frames they aren't needed. We'll advise how many and which box corners your structure needs.

How much do aluminium corners cost?

The price depends on type and size: simple 2-way corners are more affordable, T and cross 3/4-way ones pricier due to more complex geometry, and box corners with 5–6 outlets and adjustable ones the most expensive. The truss cross-section size (290/390 mm), brand and connection system also matter. Corners are usually added to a main truss order. For rental companies and institutions, Prozorro tenders and bank transfer are possible. Check current prices and availability with a manager, as the range is updated. Send the truss system and structure layout and we'll calculate the corners needed for the budget.

Is there delivery and instalments?

Yes. We deliver across Ukraine via Nova Poshta; consultation and pickup are in Kyiv (Olzhycha St 15, Dorohozhychi metro). Corners are convenient to add to a truss and connector order. Instalments are available via PrivatBank and monobank — up to 12 payments. For rental companies, cultural institutions and business we work with Prozorro tenders and bank transfer with VAT. We'll help with compatible corner selection and technical data for structural calculation. We'll advise a convenient payment and delivery option for your order. Tel. +380 (73) 060 01 01.

Aluminium Corners with Discount

Q: What are aluminium truss corners?

Aluminium truss corners (corner blocks) are elements of a truss system that join truss sections at an angle and let you build more complex structures from straight spans: frames, portals, grids and 3D frameworks. Instead of joining trusses only in a line, a corner sets a turn or branch in the required direction. They come in two-way (90° turn), three-way (T-shaped), four-way (cross) and box types with 5–6 outlets for 3D structures. Corners belong to the same system and size as the trusses (for example 290 mm). These are critical load-bearing nodes, so compatibility and calculation matter. We'll advise corners for your truss and structure.

Q: What corner types are there?

By number of directions: 2-way — a corner block with two outlets (usually a 90° turn), for frames and span turns; 3-way — T-shaped, to branch a third truss; 4-way — cross, to intersect two spans and build grids; box corners — 5–6 outlets, for 3D structures, portal corners and frameworks. Separately there are adjustable (book) corners with a variable hinged angle for non-standard turns. The shape and number of outlets determine which structures you can assemble. We'll advise the right corner type for your layout.

Q: How to choose a corner for my truss?

A corner must belong to the same system as your trusses: match the cross-section size (for example 290 or 390 mm), tube diameter, connection type (conical spigot or bolt) and usually the brand. A Global Truss corner for the F34 system joins trusses of the same series but not necessarily another maker without checking. First identify the system and size of your trusses, then the required geometry (2/3/4-way or box). If unsure, send the make and size of your trusses and the structure you're building, and we'll pick compatible corners. We'll advise geometry and compatibility for your system.

Q: What is an adjustable (book) corner?

An adjustable, or book, corner is a hinged corner block whose angle between two directions can be changed rather than fixed at 90°. It lets you join trusses at an arbitrary angle for non-standard turns, angled frames and curved-looking structures. Such corners are useful for design stages, arches and unusual installations. Because of the moving joint, they need special attention to locking and load calculation. For regular rectangular portals, fixed 2-way corners are enough. We'll advise whether you need an adjustable corner or a fixed one will do.

Q: Do corners hold the same load as the truss?

Corners are critical structural nodes, and they often determine the real strength of the whole assembly, since loads concentrate at turns and joints. Makers state allowable loads for corners separately, and they may differ from a straight truss section's load. So when designing a structure, calculation accounts for the nodes, not just the straight spans. Since structures often carry weight over people, calculation and assembly should be done by rigging specialists. We'll provide corner technical data for calculation. Don't cut corners on load-bearing nodes.

Aluminium truss corners — joining trusses at an angle

Aluminium truss corners (corner blocks) are elements of a truss system that join truss sections at an angle and turn straight spans into more complex structures: frames, portals, grids and 3D frameworks. By number of directions they come as 2-way (90°), T-shaped 3-way, cross 4-way and box corners with 5–6 outlets for 3D structures. Corners belong to the same system and size as the trusses (290/390 mm). At SoundsGood you'll find Global Truss, Prolyte, Duratruss, Milos and other brands, certified aluminium, official warranty, delivery across Ukraine and Prozorro tenders. We'll advise corners for your truss and structure.

🆚 Corner types by connection

The number of directions and shape determine which structures you can assemble. Here's a guide.

Type	Outlets	Shape	Use
2-way	2	90° angle	Span turn, frame
3-way (T)	3	T shape	Truss branch
4-way (cross)	4	Cross	Intersection, grids
Box	5–6	Cube	3D structures, portals

🔍 What to look for when choosing

🔗 Truss compatibility

The corner must match the trusses by size (290/390 mm), tube diameter, system (spigot/bolt) and usually the brand.

📐 Connection type

The number of directions (2/3/4) and the angle set the structure geometry. For 3D use box corners, for non-standard angles — adjustable ones.

🧊 Plane

Flat corners join trusses in one plane (horizontal frames), box corners in several at once (3D frameworks).

⚖️ Load & certification

Corners are critical load-bearing nodes; go by the maker's data and trust calculation and assembly to rigging specialists.
