KrampeHarex fibres

Flexible all-rounders for innovative construction.

From steel fibres through glass fibres to fibres made of plastic – the KrampeHarex product range is as diverse as the construction and planning projects of general contractors and engineers.
The supply situation never gets particularly tight, because we have been drawing our own wire ever since 2003, enabling us to control the entire value chain from the feedstock through to the finished fibres.

This also enables us to guarantee consistently high quality for all steel grades and fibre geometries. Specialist fibres, such as KrampeFibrin polypropylene fibres, comply with special requirements such as fire resistance ratings F60 and F90. No matter what your construction project comprises and what requirements you have to meet, we’ll work with you to find the ideal fibre solution.

Applications

Industrial floors

High quality, low maintenance and long service life: Steel fibre reinforced concrete floors with KrampeHarex fibres.

To Industrial floors

View of a long, empty tunnel with concrete walls and railway tracks down the center, illuminated by soft lighting.

Tunnel construction

Sprayed concrete, in-situ concrete, tubbing segments: KrampeHarex fibres provide fast and cost-effective reinforcement including fire protection.

To Tunnel construction

Modern building with a perforated metal facade, illuminated at dusk, surrounded by a landscaped area.

UHPC

Ultra high-strength concrete with KrampeHarex fibres is used to create exceptionally thin but extremely stable components.

To UHPC

$Glowing components made of refractory concrete with fibres in an industrial high-temperature environment$

Refractory concrete

KrampeHarex steel and stainless steel fibres increase resistance to heat and prevent high temperature corrosion.

To Refractory concrete

Concrete slabs stacked vertically against a blue sky, creating a narrow pathway between them.

Precast elements

KrampeHarex fibres are the ideal reinforcement for pipes, shafts, tubbings, precast basements and other precast elements.

To Precast elements

Dark mineral tunnel with irregular rock walls and an illuminated tunnel floor leading toward the tunnel entrance.

Mining

Reinforce mines quickly and easily with steel fibre reinforced concrete: KrampeHarex fibres ensure maximum safety.

To Mining

Aerial view of a highway interchange with multiple roadways and a roundabout surrounded by forests and grassland.

Traffic areas

Less effort, maximum safety and a durable surface - this is what steel fibre reinforced concrete ensures in traffic route construction.

To Traffic areas

Close-up view of two metal heads on a safe with banknotes visible in the background.

Security technology

Extremely impact-resistant and with high resistance to dynamic loads: safes and ATMs made of steel fibre reinforced concrete.

To Security technology

Close-up of a concrete building under construction, showcasing exposed floors and rebar framework.

Residential construction

KrampeHarex fibres made of steel, synthetic and glass enable time-saving, cost-effective construction with high long-term stability.

Know why

every fibre is a promise

From industrial floors that are driven on by vehicles with hard tyres and heavy loads, through tunnels that have to withstand extreme loads and blast furnaces that are exposed to great heat, to structurally relevant assemblies in silo constructions – KrampeHarex fibres enable concrete structures to comply with the most stringent requirements for safety, stability, wear and fire resistance.

With innovative solutions, outstanding quality management and our KrampeHarexPlus philosophy, we guarantee that customers located in more than 50 different countries are satisfied with what we give them. Even when it’s necessary to meet demanding deadlines and deliver large quantities of fibres within the shortest possible time.

State of the art

We meet the building standards of the DAfStb and DBV (German Society for Concrete and Construction Technology) as well as international standards.

Optimum concrete characteristics

Our fibres optimise contraction and post-cracking behaviour, distances between joints, fire resistance, etc.

Combined solutions

We exploit the synergies of different types of reinforcement and find the best solution for every application.

Sustainability

We produce with 100% green electricity and highly efficient technologies. According to our EPD, this makes our fibres extremely low in emissions, as well as up to 84% recyclable.
