The idea behind our KLEMP system is to produce fast and hassle-free pipe connections.
The fittings we developed ensure versatility, allowing you to build any structure.
A fastening screw with a hex key socket provides a secure and strong connection to the pipe. Stainless steel screws are also available on request.
Steel and aluminum pipes are commonly used as a structural element, and like all elements, they need to be connected.
What then is the first method that comes to your mind? Welding, right? However, before you opt for this solution....
Explore KLEMP fittings, which allow you to build all kinds of steel and aluminum pipe structures without the need for welding, specialised personnel, professional equipment or long lead times.
The KLEMP fitting system is your partner for the construction of safe balustrades, handrails, railings and many other structures both in industry and for private use. We supply pipes up to 300 cm in length, so making larger structures won't be a problem.
We have up to 600 distinct variants of fittings available. 75 types with 8 different diameters and 3 coating options. Such a wide assortment guarantees that you will find a fitting that is suitable for your structure and that you will complete the construction without using any specialised tools.
KLEMP fittings are TÜV approved, which means you can be sure of their of safety and durability. Also, they are made of hot-dip galvanised cast iron, which makes them highly corrosion- resistant and durable.
You install and remove KLEMP pipe fittings with an allen wrench.

KLEMP.
Steel and aluminum pipes have been used as a construction element for many years. They are durable, have no sharp edges and are readily available anywhere in the world. The problem with using steel and aluminum tubing to build various structures is the issue of connections. Threaded pipe must be delivered to the job site in a precisely defined size and offers virtually no flexibility in installation. Welding requires skilled personnel, is a complicated and time-consuming process, and requires specialized equipment.
From simple protection of platforms or walkways in workplaces to safe railings in the harsh environment of harbor quays, bridges or canals. The KLEMP pipe connection system offers complete solutions that allow you to carry out such projects.
From simple protection of platforms or walkways at workplaces to safe railings in the harsh environment of harbor quays, bridges or canals. The KLEMP pipe connection system offers complete solutions that allow you to carry out such projects.
Central to the design principles of the KLEMP system is the principle of realizing a quick and easy connection of pipes. Our connectors provide the versatility to build any design. The KLEMP system consists of cast iron, galvanized connectors. We have developed a wide range of connectors in six different sizes. The hexagon socket clamping screw provides a secure and tight connection to the pipe. Stainless steel screws are available upon request.
KLEMP pipe couplings are easy to assemble and disassemble with an Allen wrench, reusable.
The pipe couplings are fixed with a hexagon socket screw. In this way, any desired design can be perfectly realized, whether it is complex or rather simple - the possibilities are almost unlimited, as the choice of different types of pipe connections means that almost anything is possible, whether you are working with aluminum or galvanized steel pipes, as long as the correct diameter is maintained.
Thanks to the simple design, our connectors allow for very quick assembly, which significantly reduces labor costs.

Each tube description provides outer tube diameter. In addition, another value provided for a given dimension (e.g. 42x2, 42x3) determines the thickness of the outer wall of the tube. The tube diameter reflects the outer diameter. The associated tubefittings have the same tube diameter in the product name, therefore you always know whether you have the correct size of a connector for your tube. The inner diameter of the fittings is slightly bigger, so you can easily slide them over the tubes.
Shipment of oversized loads, i.e. exceeding 120-140 cm, is associated with high transport costs that we incur on the delivery of our products. We sell goods to all EU countries, which in the case of such loads is often associated with a large distance and a non-standard size of the packaging. Weight is another criterion important especially in the case of the purchase of heavier tubes (steel). However, the most important factor affecting the cost of shipping in this case is the length of the load.
No. Due to the already assumed tolerance for cutting (2-3 mm), the adopted length possible to order was rounded to full cm
The very depth to which a tube goes in the connector depends on the tube connector used and its diameter.
The tube usually goes inside the fitting at the depth of at least 2 to 3 cm.
Usable dimensions can be found in the technical illustration of each tube connector.
The diameter of the tube provided first indicates the outer dimension, followed by the sign "x" after which stands the thickness of the tube wall.
Our steel tubes are hot-dip galvanized. This means that the steel tubes are coated with a layer of zinc, which makes them resistant to corrosion. The tubefittings are made of cast iron and are fully galvanized. As a result, they are also suitable for external use.
Tubes made of steel are stronger and stiffer. For this reason, steel tubes are often used for structures that are exposed to heavy loads and characterized by larger spans. Due to their industrial nature and resistance to scratches, steel tubes are also often used in the manufacture of furniture. Their disadvantage as compared to aluminum tubes is that steel is much heavier. Aluminium tubes are often used for advertising structures. This is to avoid adding up unnecessary load.
An aluminum tube, compared to a steel tube, is more susceptible to bending over long intervals. According to our calculations, the maximum distance between two supports (for a wall frame) or two supports (for a freestanding frame) is 150 cm. It is worth noting that steel is much heavier than aluminum. The actual weight per meter can be found in the product description. If you need additional strength calculations, we recommend consulting a constructional engineer or scaffolding specialist.
All tubes are suitable for external and internal use.
Galvanized tubes were covered with a protective layer against atmospheric factors using hot-dip galvanizing.
Aluminium tubes (black) are naturally suitable for external use as they get covered with a protective layer as soon as they come into contact with oxygen.
Black steel tubes are protected from the weather conditions by a black UV-resistant coating.
In the course of time corrosion may occur in damaged places and at the edges of the cuts.
Rust does not affect the strength of the structure and can usually be removed.
For galvanized steel tubes and raw aluminum tubes, the maximum length is 600 cm. Black tubes - 300 cm.
You can order the tubes in maximum length of 300 cm through the shopping cart at our store. If you need longer tubes, please contact us by e-mail.
We cut the tubes to the desired length. Tubes can be cut starting at a length of 5 cm. We do not charge any costs for cutting the tubes. You can select the desired length on the product page and the price will instantly show up.
The diameter of the tube you need depends on the structure, the span and the weight that the structure is to support. Tables are often made of tubes with a diameter of 42.4 mm. Coat hangers, stair railings, clothes hangers and cabinets have diameters of 26.9 mm and 33.7 mm. For large projects such as canopies and pergolas, diameters of 42.4 mm or 48.3 mm are often used. Click here for a full overview.
Our tubes are stable and made of durable material. Thanks to their high quality, our tubes are resistant to damage. However, minor scratches may appear on the external surface of the tubes.
Galvanized steel tubes are resistant to scratches and impacts, and thanks to their sturdy look, any possible scratches will not be noticeable. Aluminum is prone to scratches and can be more easily damaged due to the softness of the material. The black tubes are covered with an impact-resistant coating. Despite the coating, we recommend careful handling of the tubes as the coating is sensitive to scratches, especially with sharp objects.
