Access for Services

One of the major benefits of using open web joists is that they are designed to easily accommodate services and utilities within the floor void area without the need for any cutting, notching or drilling. This should NEVER be undertaken without the joist manufacturer’s approval. Joist depths may be varied to suit particular duct requirements.

The product delivers ease of access for services, allowing wiring, plumbing and ducting to be accommodated under the floor without the need to cut or drill holes in the joist. With the increasing specification of Mechanical Ventilation and Heat Recovery (MVHR) Systems adding to the services occupying the floor zone, metal web joists look set to continue growing in popularity for many years to come.
