Structural Hollow Section: 5 Non-Standard Uses

Structural Hollow Section is one of the most versatile metal products, combining geometric precision, high strength, and ease of processing. In modern construction and design, it has long gone beyond classic applications in frames, floorings, and fences.

What is a Structural Hollow Section?

A Structural Hollow Section is a hollow metal steel pipe with a square, rectangular, or oval cross-section. Square and rectangular profile pipes are typically manufactured according to standards such as EN 10219.

A feature of such pipes is that the main load in the structure falls on their walls, not on the internal space. Thanks to this, a profile pipe can withstand loads similar to solid elements but has significantly less weight. And lower weight means a lower total cost of the future metal structure.

Production is carried out by welding hot-rolled or cold-rolled steel sheets.

For most tasks — from creating a greenhouse frame at a summer cottage to welding a rack in a garage — classic standard welded structural hollow section is ideal. This is the most common and affordable option, which is easily cut and welded even at home.

Architects, designers, and engineers are increasingly using profile pipe as a material for creativity — due to its ability to form complex structures with clear geometry while maintaining low weight and high stability.

1. Architectural Facade Grilles and Sun Protection Systems

Modern buildings with large glazing areas require not only aesthetic but also functional solutions for sun protection. That is why profile pipes are actively used to create Screen systems and facade modules that:

• form a dynamic visual effect;


• protect premises from overheating;


• reduce air conditioning costs;


• hide technical elements of the facade;


• emphasize the corporate style of the building.

Advantages of Structural Hollow Section in facade systems

• Lightness with high rigidity.


• Arbitrariness of form: vertical, horizontal, diagonal elements.


• Possibility of creating "living" facades with a variable angle of lamella rotation.


• High resistance to wind loads.

Important advice: Since facade elements are constantly exposed to rain, snow, and sun, regular metal will quickly begin to rust and spoil the appearance of the building with red streaks. For outdoor decorative structures, we strongly recommend using galvanized structural hollow section. Factory zinc coating reliably protects the metal from corrosion for decades, and you will not have to repaint the facade annually.

Trends for 2024–2026

• parallel sun protection lamellae of different sizes;


• perforated elements combined with pipes;


• metal building envelopes with illumination;


• "pixel" facades formed from short pipe sections.

2. Loft Furniture and Interior Structures

The fashion for metal in the interior is not only preserved but also expanding. Profile pipe is the ideal material for creating modern furniture that combines strength, conciseness, and style.

Based on profile pipe, the following are manufactured:

• frames for tables and work surfaces;


• bar counters;


• open wardrobes and storage systems;


• decorative partitions;


• hanging shelves;


• modular furniture structures.

Advantages of profile pipe for furniture

• You can create both massive industrial structures and light minimalist forms.


• Powder coating allows you to get any style — from matte black to bright accent colors.


• Combines perfectly with wood, stone, glass, concrete.

For manufacturing furniture, a thick wall is not needed, as the loads here are much lower than in construction. Excess weight will make a table or shelf inconvenient. Loft furniture makers usually choose standard welded structural hollow section with a wall thickness of 1.2 – 2 mm. It is light, welds perfectly with a semi-automatic machine, and after cleaning the seams, it is ideal for powder coating.

Latest Novelties

• transformer furniture;


• complex geometric shelves;


• interactive structures with illumination;


• modular open space interiors.

3. Mobile Modular Structures

In the 21st century, temporary structures have ceased to be something secondary — they must be strong, stylish, and quick to assemble. Profile pipe ideally meets these requirements.

Where it is applied:

• exhibition stands;


• pavilions for events;


• mobile stages;


• mobile advertising structures;


• modular public spaces.

Advantages of profile pipe in mobile objects

• possibility of multiple assembly and disassembly without loss of rigidity;


• low weight, which simplifies transportation;


• minimum number of fasteners;


• clear geometric shapes and accuracy of element fitting.

When the key factor is assembly speed and structure budget, the best choice becomes regular welded structural hollow section of medium sizes (for example, 40x40 or 60x40). It provides the necessary frame rigidity for an exhibition stand or a mobile coffee shop, remaining affordable.

Modularity has become one of the key trends in construction of the future, and profile pipe is the main material for such solutions.

4. Designer Canopies, Pergolas, and Small Architectural Forms (SAFs)

When building canopies and SAFs, it is important to combine aesthetics and engineering. Profile pipe allows creating structures of any complexity and shape.

Where used:

• park canopies;


• pergolas and gazebos;


• bus stop complexes;


• entrances to public buildings;


• small architectural forms for recreation areas.

Advantages of profile pipe for SAFs

• Lightness of construction — minimum load on the foundation.


• Resistance to natural conditions.


• Visual neatness and conciseness.


• Flexibility in choosing the shape — from rectilinear structures to complex curved elements.

As in the case of facades, the main enemy of gazebos and canopies is moisture. Using ordinary metal will require careful priming and painting in several layers, and subsequently — regular renewal of the coating. To ensure your pergola or canopy serves long without unnecessary trouble, choose galvanized hollow section for all outdoor frames. This is an investment in the durability of your recreation area.

Popular Styles

• hi-tech;


• minimalism;


• Japanese restrained design;


• modern landscape urbanism.

5. Decorative Exterior Elements: Art, Illumination, Installations

Profile pipe is increasingly used as part of artistic and decorative objects that become central elements of urban space.

Where applied:

• art installations and sculptures;


• structures for LED illumination;


• decorative elements of landscape design;


• designer fences;


• geometric "skeletons" in public parks.

Advantages for artistic solutions

• thin but strong elements can be created;


• the pipe holds its shape well;


• amenable to cutting, bending, perforation;


• makes it possible to create spatial figures without massiveness.

If you are creating a complex sculpture where the perfect geometry of every millimeter, the absence of a visible visible weld seam, and increased bending strength are important (for example, in thin tall structures), pay attention to seamless hollow section. It is more expensive than regular pipe but ensures impeccable appearance and reliability for premium designer objects.

Conclusion

Today, profile pipe is not just a structural material. It is an instrument of architectural freedom that allows:

• creating individual facade solutions;


• forming a modern interior;


• building mobile modular structures;


• making urban spaces more functional and aesthetic;


• realizing bold design and artistic ideas.

It combines high strength, precision, and architectural expressiveness, therefore it continues to expand its areas of application in modern construction and design.
