Quinn Precast hollowcore flooring units are machine cast concrete slabs, with tubular voids extending the full length of each slab, creating a light weight building unit, saving money on materials and transport costs.
All Quinn hollowcore products are produced to the highest quality standards and conform to current European, British and Irish standards. The design of the units is in accordance with EN 1168 and the characteristic strength at 28 day test is 50 N/mm2.
The precast hollowcore flooring system eliminates costly excavation, provision and compaction of infill and provides an immediate dry working platform.
Large open spaces can be created with minimum use of internal support and, with the excellent span/depth ratio, overall construction height can be minimised.
This flooring is suitable for both domestic and commercial buildings and is supplied is supplied in lengths to site requirements ranging in depths from 150mm to 400mm.
Alternative shapes and widths are available to order and the Technical by Quinn Team provides advice and guidance on floor plans for layouts, spans and loadings.
The Technical by Quinn Team can also prepare layout drawings with design details and support calculations to assist you with your construction project when selecting your precast products.
