Metal Web Joists

Truss Form designs and manufactures the posi-joist metal web joist system. Metal web joists are commonly known as posi-joists, easi-joists, space joists, or eco-joists.

These joists outperform sawn timber in span and dimensional stability. Furthermore, the added benefits of a greater bearing area and open web system make them easier to install for the carpenter, plumber and electrician, reducing your time and cost expenditure.
