At Minera Roof Trusses we are always evolving to satisfy the requirements of an ever changing market whilst operating within a constantly developing industry. For over 40 years, we have been at the forefront of our market, both in terms of supplying professional products and providing our customers with the highest quality of service.
Alongside our Roof Trusses and Attic Trusses we also supply an eco-friendly engineered floor joist product: the Open Metal Web Floor Joists (also known as Posi-Joist | Ecojoist | Easi-Joist | Spacejoist).
This is a revolutionary new product. It is a fully engineered floor joist which has been designed with two major factors in mind:
With traditional floor joists, sizes of 225 x 50 or 225 x 75mm are used. With an Engineered Floor Joist - Open Metal Web Floor Joists (Posi-Joist | Ecojoist | Easi-Joist | Spacejoist), the only timber that is used is 97 x 47mm. The floor depth can still be 219mm deep, but the key difference is that the middle of the web is not made from timber, but actually consists of a V shape Metal Web. Thus reducing the amount of timber used in your project whilst also having the advantage of assisting trades when installing cabling and piping.
How can an engineered floor joist only use 97mm x 47mm timber and still work at 219mm deep?
The special V plate is made of high quality galvanised steel. Each joist is specially designed and engineered by our resident engineers to the correct loading for your project, for example, residential loading to office loading to flats loadings. Engineered Floor Joists - Open Metal Web Floor Joist (Posi-Joist | Ecojoist | Easi-Joist | Spacejoist) can be used in any of those conditions.
In addition you are not restricted to one type of decking. Floor material can range from Chipboard to plywood or concrete screed. If you supply our engineers with the information as to exactly what you wish to do with your floor then Minera Roof Trusses can design an Engineered Floor Joist - Open Metal Web Floor Joist (Posi-Joist | Ecojoist | Easi-Joist | Spacejoist) floor to suit your needs, Free of charge from our renowned Technical Support service.
Our engineered floor joists with the open metal web are also extremely trade friendly. They have been designed with the trades in mind, aiming to make the builders, electricians and plumbers job that bit easier.
The design shape of our Engineered Floor, the Open Metal Web Floor Joist (Posi-Joist | Ecojoist | Easi-Joist | Spacejoist) allows for the easy quick installation of ALL your services. No more drilling or notching to allow for all your pipes. Our Engineered Floor Joist with the open metal is shaped this way so that all your services; wiring for your lights, electrical plug sockets and home entertainment cabling, copper pipework or plastic pipework and vent ducting, can all be installed between the V Shaped Webs.
This also has the added benefit of a much quieter finish (drilling or notching a traditional floor joist weakens your joist and that is what will give you squeaks as your timber is deflecting more than it is allowed to.)
And with MHVR - Mechanical Ventilation & Heat Recovery becoming increasingly popular, the open metal web floor joist system (Posi-Joist | Ecojoist | Easi-Joist | Spacejoist) is becoming more and more popular and the number one choice over the I-Joist system.
