Extruded fibre-reinforced concrete spacers

FRANK’s range of extruded fibre-reinforced concrete spacers ensures that the specified concrete cover to the reinforcement for structures and structural elements is achieved, both before and during concreting. These spacers help to guarantee the durability of all structures.

Spacers made of fibre concrete have an optimum material compatibility with in-situ concrete. FRANK spacers are produced in various grades with strength and durability properties to match most site and precast concrete applications. The outstanding material properties of fibre-reinforced concrete include:

• High compressive strength, accurate dimensional tolerances, no deformation with temperature fluctuations, excellent physical and chemical resistance
• Excellent bond with concrete, no hairline cracks between the spacer and concrete, suitable for impermeable concrete
• Fire resistant to the highest requirements specified in EN13501-1:2002 - Class 1A
• The performance of FRANK spacers meets all international standards

FRANK’s wide range of  single spacers and bar spacers offers the ideal spacer for any application. We manufacture extruded fibre-reinforced concrete special spacers with special dimensions, shapes and colour upon request. From support profiles for internal formwork in bridge building to finely detailed spacers, we can offer numerous technically ideal solutions.

Spacers are used e.g. for precasting plants, for drinking water reservoirs, for tunnel constructions or for exposed concrete surfaces.

FRANK extruded fibre-reinforced concrete spacers have been awarded the KOMO attestation with product certificate according to the Dutch assessment guideline BRL2817. This certificate confirms that the manufacture of extruded fibre concrete spacers by FRANK is in full conformity with the requirements of Dutch construction and environmental legislation for construction materials.

KOMO certification requires proof that the production quality system meets the strict requirements of criteria 73/06. This regulation requires that all aspects of the process including test systems inspection, dosing and mixing equipment, incoming-lot control of raw materials, concrete production and final product inspection as well as all aspects of quality control are complied with.

NL-BSB product certification issued in conformity with the Dutch assessment guideline requires that all construction products fulfil the Dutch legal requirements with regard to environmental hygiene. FRANK extruded fibre concrete products have been certified as meeting all requirements for concrete products which are designed for outside use.

Certification not only includes spacers but also permanent edging formwork and shutter panels made of fibre reinforced concrete. Permanent formwork is used as formwork for precast elements (balconies, slabs, etc.) and twin-wall construction. Shutter panels are used as floor-edge forms and as a covering for joints in insitu construction.
