Looking for high-quality galvanized steel tubes? You’ve come to the right place. We supply galvanized tubes in various diameters and lengths, perfect for safety railings, handrail systems, industrial furniture, and construction projects. All tubes are available cut to size and ready for your next project.
Galvanized steel tubes
Our galvanized steel tubes are the standard choice for key clamp constructions. The tubes are strong, durable, and suitable for both light and heavy-duty applications. We offer five different diameters, all available cut to your required size — up to a maximum length of 640 cm.
For cost-efficient shipping, we recommend keeping tube lengths below 300 cm. If your project requires longer tubes, please contact us for advice on minimizing shipping costs.
Each tube is hot-dip galvanized, providing long-lasting protection against corrosion and weather conditions. This makes our tubes ideal for both indoor and outdoor use, especially for railing systems exposed to the elements.
Galvanized tubes for safety railings
Galvanized steel tubes are the preferred choice for handrails, guardrails, and safety barriers in both commercial and industrial environments. The 42.4 mm and 48.3 mm diameters are most commonly used for handrail fittings and comply with standard railing dimensions. Their strength and corrosion resistance ensure long-term stability and low maintenance.
Our range of key clamps allows you to build custom handrails and guardrails quickly, without welding. Whether for stairs, platforms, mezzanines, or public areas, these tubes form the foundation of a safe and professional-looking railing system.
Tube clamps and fittings
To complete your construction, combine our galvanized tubes with our full range of key clamps. These fittings make it easy to build strong, stable, and customizable structures. Whether you’re creating a frame, rack, railing, or canopy - the right key clamps will securely connect your tubes in place.

The benefits of galvanized tubes
Galvanized steel tubes are exceptionally strong, impact-resistant, and built to last. The zinc coating applied during the galvanization process protects the tube from rust and external damage, ensuring durability even in demanding environments. These tubes are perfect for long spans, load-bearing structures, and outdoor constructions such as canopies, railings, and fencing systems.
Industrial furniture made with galvanized tubes
Galvanized tubes are also popular in furniture design, including racks, tables, coat stands, and shelving systems. Their robust, metallic look perfectly complements today’s industrial interior trend. Combine our key clamps with custom-cut tubes to create stylish and sturdy pieces of furniture.
The tube diameter plays an important role in the final appearance. For example, 42.4 mm tubes are perfect for solid tables or heavy-duty frames, while 26.9 mm tubes create a more minimalistic design ideal for smaller furniture.
