Fast, accurate beam specification for residential and commercial projects.

Radiata Pine can be specified in H1.2, H3.2 and H5 for in-ground posts.

Specify two structural grades in glulam: PL8 & PL12 providing size options depending on the space available for the beam. PLX20 is also available for specification for a range of situations.

Caters for variances in roof height caused by product type, thickness of ceiling plasterboard or additions such as solar panels. You can also allow for the extra high wind zone recently added to the Building Code.

Software includes deflection and capacity ratios. Shift a point load to exactly where it will be on the beam and The Prolam Specifier will adjust the results to suit. Also defines the long-term deflection a beam will settle out at.

I use your products a lot. I find the Specifier easy to use and being able to get a PS1 certificate for the products is great.

We have used the Prolam Specifier for numerous projects. This is a vital tool for an architect and is a factor in the selection of glulam timber products we specify for the homes we design.

The ease of using the Prolam program makes specifying a

Prolam specifier is free, easy to follow, comes with the PS1 which is a very smart way to allow switching any other beams to Prolam beams.
