Length of straps according to customer requirements.

Tensioning system Tension is set by a composite / Super duplex ratchet, using a torque wrench tool

Tension is set by a double-bolt tensioner

Tension is set by a single-bolt tensioner

Minimum breaking load 16 kN 30/50/75/100/125/200 kN 30/50/75/100/125/200/350 kN

Optional Can be delivered with pneumatic/hydraulic/electrical installation tools, which secure a fast, quick and even tensioning of the strap. Tape material is supplied in reels, so the required length of strap can be cut-off-in-situ.

Tensioners can be supplied in Super Duplex; Stainless steel, Coated steel and galvanized steel, depending on the application for the strap. Double bolt tensioner is smaller in dimension, compared with a single bolt tensioner, as there are 2 bolts carrying.

Tensioners can be supplied in Super Duplex; Stainless steel, Coated steel and galvanized steel, depending on the application for the strap. A single bolt tensioner is easy to tension and will ensure a more even load distribu-tion on the strap.

One Material- various applications

Roblon straps with high strength, no corrosion and various dimensions can be used for many different applications, such as elevating, deploying, strapping, securing, hanging up, fastening – or perhaps you have an entirely different job for the Roblon straps.

Floating elementsThe example underneath shows Multi straps used to secure a floating element to a bridge deck in a pleasure boat harbour.

Securing pipes to the subsea foundationTypically used to be attached to concrete gravity anchors and large span supports for tie-in spool stabilization.

No corrosion and resistant to chemicalsRoblon straps are made from high performance fibers and coated with a jacket material – and thus the straps do not corrode – compared to steel straps.

The straps are gentle to any surface below the strap – No sharp edges.

When used subsea the expected lifetime of the straps is minimum 30 years.

High strengthRoblon straps can be supplied in various strengths according to customer requirements, from 3 tons up to more than 500 tons.

Roblon supplies straps, suitable for a wide range of applications and to be used under different conditions.

We will always be able to supply you with a strap suitable for your specific requirements.

Low weight – and still high strengthCompared to steel straps, you can get the same strength with a Roblon strap – but at a much lower weight.

Compared to high-strength steel grades, the strength of the Roblon straps is up to 10 times stronger per weight unit.

Safe to useNo personal protection equipment (PPE) required.No sharp edges.

Easy to installRoblon straps are easy to install in no time – even under water and with simple handtools.
