Wyder Engineered Timber Systems is a Distributor Partner of Steico. Steico I-Joists fulfil the demands from house builders for greater clear spans and better dimensional stability. I-joists have a high strength to weight ratio when compared to its equivalent solid timber section and they are up to 50% lighter meaning they are much easier to handle on site. With modern builds now requiring more pipes for plumbing and air conditioning the installation of services within intermediate floors can cause problems, leading to unnecessary deep floor build ups and increasing costs. Using Steico I-Joists you can drill access holes in the web without a reduction in the load bearing capacity of the beam, providing the holes adhere to the Steico hole charts, which are supplied to site for guidance.
