Beam properties

The beams are pre-fabricated in specially designed moulds and are ready to be installed within 7 days. Properties include:

• Cast in Innovative system utilising reinforcing steel
• Concrete cube strength: 50MPa three weeks after moulding
• Dimensions: height = 200mm, weight  = 35kg per metre
• Deflection (6.2m beam only) : 1000kg load, no deflection.
• Deflection (6.2m beam and 60mm slab): 3800kg load, 15mm deflection
• Tested for compliance with SABS0160 and SABS 0100

Beams ready for installation

Polystyrene properties

The polystyrene void fillers are manufactured from EPS to fit the space created by the 620mm beam spacing and 200mm beam height. Other properties include:

• Thermal resistance “R” value: >3.7
• Fire: classified as B / B1 / 2 / H&V.  Suitable for use in all industrial , residential and commercial buildings as an under-roof and side cladding insulation material.
• Moisture: non-hygroscopic and not affected by moisture.
• General: not affected by bacteria, mould or fungi and have no nutrient value for insects, birds or vermin. They will remain effective as an insulant for the life of the building.
• The polystyrene used is manufactured from recycled waste polysytrene

Installation of polystyrene void fillers

Wire mesh is placed over the installed beams and polystyrene void fillers. Concrete is then placed onto the mesh to form a monolithic slab structure. The properties of the materials used in a standard installation are:

• Mesh: grid 193 with 5.5mm wire
• Slab thickness: 60mm
• Concrete cube strength: 25MPa (28 days)

This standard has been found to meet the needs of most customers however the specifications can be changed to meet any variance in engineering requirements.
