I-Joist

These structurally engineered timber joists are used in many new homes. They are made from a web sandwiched between top and bottom flanges, which is glued, pressed and heat cured. The I-shaped cross- section gives them their name, but also means they can carry far heavier loads than a conventional timber joist of equivalent weight.

Crendon Timber Engineering offer James Jones JJI Joists from stock, which are available in a range of depths and thicknesses in lengths up to 14m and offer a very cost-effective alternative to solid timber for floor joists and flat roof members, eliminating the shrinkage, splitting, and warping common in traditional floors. For all projects Crendon provide:

• Trusses packaged to suit customer’s on-site programme.
• Clear drawings pack with each delivery.
• Labelled to site requirements to assist in site erection.
• A commitment to ensure safety on-site.
