What is a Metal Web Joist?
Metal web or Posi joist systems are a combination of timber chords and pressed metal webs which together form an ‘open-web’ joist. Their open web design allows for the installation of services such as pipework, cabling, mechanical heat recovery systems and other services to be passed through the metal webs without the need for notching or drilling. Posi Joists also reduce site wastage and are environmentally sustainable.
Where is a Metal Web Joist Typically used?
At DTE we manufacture both posi joists (floors) and posi rafters (roofs). To clear up any confusion regarding the two products, Tom has explained the different applications of each below:
Posi joists (floors) can be used in all types of buildings, from domestic dwellings to large apartment blocks or hotels. Due to the span capability of the product, they are often the first choice for architects and engineers.
Posi rafters (Roofs) are typically used for a roof application, either pitched or flat. The use of a Posi rafter varies hugely from usage on a domestic dwelling, all the way up to a new build school. As the product is so versatile, our design team can adjust end details, overhangs and web formation of the rafters to suit the customer’s requirements.
What is the difference between a metal web joist and an I-joist?
This is a question that our designers often get asked. A metal web joist can typically span greater distances than a I-joist, which allows us to cater for customers who have large, clear span requirements on their projects.
Customers will reap the benefits of a metal joist when they require services to run through the floor joist. At DTE we can adjust the web formation of the metal web joist to meet the customer’s exact requirements. Whereas with an I-Joist of comparative depth, the customer is limited to how big and how close together holes can be drilled to accommodate these services.
Frequently Asked Questions:
As Tom engages with customers daily, he often gets asked many technical questions regarding joists. The most common thing DTE’s customers ask him is whether services will fit through a specific size, and if the open web joist can span a certain distance. It’s satisfying for Tom and his team to let his customers know that we can adjust our products to suit the individual needs of the customer.
