The type of rafters utilized is important when building strong and dependable roofs. Profile pipe rafter systems are a contemporary option that provide strength and adaptability. These structural components are made of aluminum or steel profile pipes and are intended to endure a range of weather and heavy loads.
There are various varieties of profile pipe rafters, each designed to meet specific structural and architectural requirements. Among the common variations are gambrel trusses, attic trusses, and triangle trusses. Regarding load-bearing capacity, span distances, and aesthetic options, each type has specific benefits.
The versatility of profile pipe rafters is one of their main advantages. They are appropriate for a variety of building designs because they can be tailored to fit various roof sizes and shapes. Profile pipe rafters can be designed to offer the best support for a variety of roof configurations, including custom pitched roofs and more intricate ones with curved or multi-pitched roofs.
Profile pipe rafters are superior to conventional timber rafters in a number of ways. Handling and installation are made easier by their high strength and tendency to weigh less. Their longevity is also guaranteed by their durability, which requires little upkeep over time.
Selecting the appropriate rafters is crucial for architects and builders to guarantee the longevity and structural soundness of a roof. Modern construction projects prefer profile pipe rafters because they offer a modern solution that combines strength, flexibility, and ease of installation.

Using the rafters from pipes
Generally speaking, metal rafters are employed in the construction of public and industrial structures. Hypermarkets, athletic complexes, workshops, and warehouses are a few examples.
Residential building roofs constructed on an individual basis hardly ever use metal. Costly, there are installation and transportation challenges. Indeed, and no requirement. It makes sense to use wood materials in this situation. But in private building, metal rafters (farms) are also given a special place. Utilize them to build different kinds of awnings, such as those for courtyards, pools, and cars (covered parking).
Among the benefits of metal farms are the following:
- high strength, which allows to withstand heavy loads;
- the ability to block large spans;
- the possibility of use on geometrically complex objects;
- durability.
The following are the drawbacks:
- large weight, when raising farms to a height, the use of special equipment is required;
- high price;
- Low resistance to high temperature, as a result of which, in case of fire, metal rafters (farms) sag and collapse in 15-30 minutes.
Profile pipe – our option
Metal farms are typically constructed from a variety of products and their combinations. Channels, corners, losers, etc. are a few examples. Profile pipes are another.
What makes a pipe good? Because of the high degree of streamlines in its contours, wind pressure is reduced. For tall objects that are subject to wind loads, this is crucial. In addition, profile pipes are easier to paint and have a higher corrosion resistance than other products because moisture (snow, hoarfrost, and water) does not accumulate on their walls. correspondingly more durable and elevated.
The profile pipes appear massive, but they are light because there is emptiness inside of them. This characteristic enables you to lessen the roof structure’s weight on the foundation and walls. However, in order to stop moisture from getting inside and causing corrosion, these cavities must be sealed off from the ends of the products.
Metal is rolled and processed on specialized machinery to create metal profile pipes. The pipe section that is obtained in this manner may be square, rectangular, or oval.
Typically, structural steel is used to make profile pipes. However, galvanized steel or aluminum alloys are occasionally utilized in the building of special purpose structures.
The brand of metal used, the product’s wall thickness, and the manufacturing process all affect the loads that the profile pipe can support.
The pipes range in length from 6 meters for small sections to 12 meters for larger sections. Minimum section sizes are 10 x 10 mm and 15 x 15 mm, with 1 mm and 1.5 mm for the wall thicknesses, respectively. Such cross-sectioned pipes are utilized for lightweight, small-scale constructions (like little canopies). An increase in section size and wall thickness causes the profiles’ weight and strength to increase. Pipes with maximum sections (300x300x12 mm and above) are therefore primarily used in industrial buildings.

The goal of this article is to provide readers with useful knowledge by explaining the various kinds of profile pipes that are frequently utilized and by looking at their special qualities and advantages in rafter construction. Discover how profile pipes can improve structural integrity and efficiency in roofing projects, whether you’re a builder looking into new materials or a homeowner planning a makeover for your roof."
Pipel farm structure
A farm is the basic building block of the rafter metal system; it is a level structure made up of multiple straight rods. The upper and lower belts are formed by the farm contour. There’s a grille made of racks and braces between them.
Straight profile pipes, or farm elements, can be connected to one another directly or via nodal styles. Use bolts, rivets, or welding to secure objects.
Standard-sized and constructed metal farms can be purchased already assembled or manually gathered from pipes. Independent manufacturing, however, necessitates a high level of professionalism as well as the capacity to accurately calculate and work with metal structures. Thus, buying pre-made farms that only need to be properly mounted is far more convenient for a private developer.
Farm structures
Metal farms can vary in terms of their design, function, and capacity to sense loads.
Upper and lower belts are the basic components of the farm. They draw out the circuit from above and below, creating a circuit. A belt is a rod made of one or more solutions that can be broken or straight.
The following are the farm belt contours as shown by the profile:
- with parallel belts (flat roof);
- trapezoidal;
- triangular;
- polygonal;
- segmented.
Farms with horizontal, or parallel, belts are the most basic type, consisting of a rectangular shape with uniformly long horizontal belts. includes a large number of the identical details found in the same length lattice. There is a single, cohesive design. This type of farm is used to construct flat roofs because its belt is horizontally exposed. Including for coatings on soft roofing.
A trapezoid (or two closed trapezes) is the shape of a trapezoidal construction. utilized when building roofs with a slight inclination. Stronger and more rigid farm nodes are their defining characteristics. Since the central section lacks long rods, the trapeziidal version is thought to use metal very sparingly.
Farms in triangles They are used to put together the gable roof (awning) rafter system, and they resemble triangles in shape. It is feasible to use on steep slopes regardless of the inclination angle. When putting together triangular farms, use a sophisticated device to precisely calculate and fix support nodes. An additional feature is the use of elongated rods in the central portion of the structure. The longer the rods, the colder the sides of the "triangle". This means that more pipe is needed during their manufacture.
Polygonal farms have intricate outlines that resemble an arched upper contour. possess greater strength; as a result, they are employed in large, hefty structures with long spans. You can save a significant amount of profile in polygonal farms because of the unique placement of the elements. but only in the case of substantial buildings. When selecting a polygonal option, light designs will not result in savings.
Segment farms are uncommon due to their intricacy. possess an arched shape, with the upper belt’s outline curved and semicircular. Because this outline replicates the diagram of the moments, the segment farm requires less metal. But once more, the intricacy of production linked to intricate construction nodes renders it highly unpopular.
Apart from the belts found in the farm’s design, a lattice is also included. This consists of a set of direct elements, such as braces and racks, arranged in a specific order between the belts to secure them together. The type of grate determines the farm’s strength, weight, appearance, and manufacturing complexity.
Common grate systems include the following ones:
- triangular;
- Satisfy;
- Sprengel;
- Cross;
- rhombic;
- Half -haired.
The components of the triangular grate system are displayed as repeated triangles. Ideal for farms with trapezoidal and parallel belts. There are two types of supporting braces in a structure: ascending and descending. The force from the points of the applied load to the support, the minimum number of nodes with the smallest path, and the minimum total grille length are the characteristics of the triangular system. In the grate, there are lengthy brackets that are used for compression. It is necessary to increase the amount of metal used in the calculation so that the brace design acquires the necessary stability. Almost the only drawback of triangle grilles is their increased profile consumption.
Salad lattice: a configuration with a lot of braces and few racks. The effort travels far, avoiding all of the grate’s lines and nodes, from the location of the applied load to the support. Braces should be able to stretch, and racks should be able to compress. The design necessitates the use of more profile because of the numerous long braces that are used. These lattices are employed in low farms that are meant to endure a lot of strain.
Sparengel grille: intricate and time-consuming to design. It is employed in tall triangular farms (4-5 m) intended for wide spans (20–24 m). You can shorten the compressed rods’ length because of where the elements are located in it.
Cross grill: racks are positioned in between the crosswise-installed brackets. Farmers that perceive a bilateral load use these lattices. This kind of load is typical of vertical bond farms of masts and towers, as well as horizontal bond farms of roofs of production buildings and bridges.
Two distinct systems are employed in semi-divided and rhombic lattice designs. They become more rigid as a result. Bridges, masts, and tower structures all use these kinds of lattices.
A strong and adaptable option for building rafters—essential components of roof frameworks—are profile pipes. These pipes are valued for their strength-to-weight ratio, which makes them perfect for supporting roof loads while remaining lightweight. They are usually made of materials like steel or aluminum. This feature lowers the building’s overall structural weight while also making installation simpler.
Profile pipes are used in a variety of rafter designs, each suited to a distinct set of structural and architectural requirements. King post, queen post, and Pratt truss designs are common; their load-bearing capacities and levels of complexity vary. Aesthetic preferences, local climate conditions, and roof span all influence the choice of rafter design.
A notable benefit of utilizing profile pipes for rafters is their ability to withstand weathering and corrosion. Over the course of the roof’s life, properly treated steel or aluminum pipes can endure harsh environmental conditions with little need for maintenance. This durability factor plays a critical role in lowering replacement and repair costs over time.
In conclusion, using profile pipes for rafters in roof construction offers a cutting-edge and effective solution. Through the utilization of their robustness, low weight, and resilience to external influences, builders can fabricate long-lasting, structurally sound roofs. Profile pipe rafters provide adaptability and dependability, satisfying the various requirements of contemporary construction projects, whether they are used in residential, commercial, or industrial contexts.
