Call Us Australian Rollforming Manufacturers produce a range of standard and custom formed steel void panels that are fitted over the concrete beams used in bridge construction to block off the void or trough in the beam when the concrete road slab is poured.
Australian Rollforming Manufacturers’ void panels provide a number of significant advantages and are a very attractive and cost-effective alternative to the traditional void covers manufactured from timber based materials.
High Strength: Australian Rollforming Manufacturers’ void panels combine high strength with low mass and have a significantly higher load carrying capacity than those manufactured from timber based materials.
Pre-cut to exact void width: Australian Rollforming Manufacturers’ void panels are pre-cut to the exact void width, therefore eliminating the need for any further cutting during installation.
Quicker, easier and safer to install: The installation of Australian Rollforming Manufacturers’ void panels is comparatively quick and easy – they are simply glued (liquid nails, sealant) into the recess in the concrete beam. This is made even easier and safer since this can be done while the beam is still in the mould and the scaffolding still in place.
Minimise wastage: Wastage on site and in storage is minimised. Australian Rollforming Manufacturers’ void panels maintain their shape and integrity when exposed to all climatic conditions; they do not swell or break when they become wet and are not subject to shrinkage.
Environmentally more sustainable: The traditional timber based void panels rely primarily on wood chips for their production and therefore have a far greater environmental impact than Australian Rollforming Manufacturers’ steel void panels.
Australian made: Australian Rollforming Manufacturers’ void panels are made in Australia, by Australians, using 100% Australian materials.
More cost-effective: As a result of Australian Rollforming Manufacturers’ void panels being quicker and easier to install, requiring less materials and labour, their overall installed costs are less than that of the alternative timber based panels.
