Steel construction connections

BeamClamp®, BoxBolt® and FloorFix® - safe connection of steel profiles

Tested connection systems for steel structures, used for joining overlapping profiles, securing structural elements, and installing floor and platform panels. No welding, drilling or weakening of the existing structure required.

Choose the right connection system

Each system solves a different installation challenge — below you will find three steel connection options available in our range.

BeamClamp®

Clamps for joining overlapping steel profiles, including flanges, angles and channels. Available as individual components or complete sets with bolts, nuts and positioning plates.

BoxBolt®

Tested structural fasteners for one-sided connections of hollow sections — rectangular, square and circular. Ideal where access to the structure is only possible from one side.

FloorFix®

Cam clamps for securing floor and platform panels to load-bearing profiles. Installed from above, without drilling, riveting or welding.

Why choose BeamClamp®, BoxBolt® and FloorFix® connections?

All three systems share the same philosophy — safe, repeatable and fully calculable connections for steel structures, without compromising their structural integrity.

Installation without welding and drilling

No welding or drilling

Connect steel profiles without hot work or weakening the structure by drilling holes.

Fast, repeatable installation

Fast, repeatable installation

Installation requires no specialist tools or skills — a spanner, Allen key or torque wrench is sufficient.

Finishes suited to different working environments: electro-galvanised, hot-dip galvanised and stainless steel.

Easy adjustment and disassembly

Easy adjustment and disassembly

Unlike welded connections, the connection can be loosened, adjusted or dismantled when required.

BeamClamp® - clamps for joining steel profiles

BeamClamp® clamps are a range of structural products designed for joining steel profiles on site. They require no welding or drilling.

They are available as individual components or as complete connection sets consisting of clamps, bolts, nuts and positioning plates.

The system is available in a wide range of variants — from clamps for flat and sloping flanges, through self-adjusting and adjustable clamps, to solutions for heavy-duty loads.

BoxBolt® - fasteners for hollow sections

BoxBolt® fasteners are a fully tested and certified solution for connecting elements to steel profiles where access is limited. The system is suitable for joining rectangular, square and circular hollow sections.

The anchor bolt features a hexagonal head for installation with a standard spanner — after drilling the hole, simply insert the anchor and tighten it to the required torque to achieve a durable and repeatable connection.

The anchors are available in seven diameters and three lengths, with electro-galvanised, hot-dip galvanised or stainless steel finishes.

FloorFix® - clamps for floor and platform panels

The FloorFix® clamp is designed for secure and stable attachment of floor and platform panels to load-bearing profiles.

The cam mechanism enables fast and precise tightening of the clamps using an Allen key, while installation is carried out entirely from above, without the need for access underneath the floor.

The clamps accommodate load-bearing profiles from 3 to 25 mm thick. They are hot-dip galvanised and TÜV certified for vibration resistance in industrial applications.

Frequently asked questions

Are BeamClamp clamps better than welding?

BeamClamp clamps eliminate hot work and the associated fire risk, while installation is fast and requires no special tools or skills. Unlike welding, the clamped connection can be loosened and adjusted at any time, and its load capacity is predetermined and confirmed by testing.

Do I need an engineer's approval to use BeamClamp clamps?

The appropriate clamps can be selected using the tables available in the product catalogue, and a separate design or engineer's approval is not required. However, since the connection must always be considered together with the load-bearing capacity of the entire structure, we recommend consulting a structural engineer.

Can I remove or reuse a BoxBolt anchor?

A BoxBolt anchor can be easily removed — after loosening the core bolt, the cone separates and the body can be removed from the hole. Reusing a dismantled anchor will not provide the declared connection parameters; however, the same hole can be used to install a new BoxBolt anchor.

Can BoxBolt anchors be used in concrete?

No, BoxBolt anchors are designed exclusively for connections between steel profiles (tubular, square, rectangular and circular) and must not be used in concrete.

What is the difference between FloorFix and FloorFix HT clamps?

Both clamps are designed for installing floor panels onto load-bearing profiles without requiring access from underneath. The HT version has an increased installation range (tolerance of +/- 6 mm) and can be used with thicker load-bearing profiles, from 3 to 25 mm thick.

Are FloorFix clamps suitable for vibrating machinery?

Yes, both FloorFix and FloorFix HT clamps have TÜV certificates confirming their resistance to increased vibration and can be successfully used with production machinery, presses and in heavy industry.

Contact us for a quote

The selection of BeamClamp®, BoxBolt® and FloorFix® connections depends on the type and dimensions of the profiles, so each quotation is prepared individually. Briefly describe the type of steel connections required and the quantity, and we will select the appropriate components and prepare an offer.

We also provide technical support with connection design and the selection of installation components.
